the buchla module 292. the term \"low pass gate\" was created by don buchla and stands for a module that can be switched between low pass and vca. the control (manually and via external cv) is responsible for frequency in the low pass mode and for loudness in the vca mode. additionally a combined mode lp+vca is available. in this mode the sound becomes more dull as the loudness decreases.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ein contrast to the buchla design the a-101-2 offers attenuators for both cv and audio input, a manual resonance control and two

filter that can be switched to vca or a combination of low pass and vca. the controlling elements for frequency (lp mode) resp. amplitude (vca mode) are so-called vactrols. vactrols are known for their smooth sound behaviour.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe frequency (in the lp mode) resp. the amplitude (in the vca mode) is controlled manually (f\/a) and by the

and is adjustable all the way up to self-oscillation. resonance and consequently self-oscillation may vary with the filter frequency because of vactrol tolerances. due to the circuit the resonance has a little bit an influence on the audio level (increasing resonance = increasing audio level). to obtain the original buchla sound the resonance control simply has to be set fully

opto fets are very similar to vactrols but use light depending field effect transistors (fets) instead of light depending resistors (ldrs). a opto fet is a combination of a light depending fet and a led (light emitting diode) both put into a small light-proof case. the advantage compared to vactrols is the much faster response of opto fets compared to ldrs. this allows much faster attack\/decay times and even fm effects. the disadvantage compared to vactrols is that the fet behaves as a normal ohm resistor only for small levels. with higher levels the fet begins to distort. apart from this

original ms20 included two filters: a 12 db lowpass and a 6db high pass filter connected in series both with a very special design (the ms20 highpass if very often described as 12db high pass, but this is not true). during our researches we found a way to use the same circuit simultaneously as lowpass and highpass for 2 different audio signals (a bit similar to the a-101-1 steiner vactrol filter that has even different audio inputs available, but with the special ms20 circuit). for this two separate audio inputs for lowpass (lp) and highpass (hp) with separate level controls are available. the sockets are normalled, i.e. the signal applied to the lp input is available for the hp input too provided that no plug is inserted into the hp input socket. the level control of the hp input is realized as a polarized input. this means that the signal can be added with the same polarity (+ range) or opposite polarity (- range) compared to the lp input. this feature enables notch (+) and bandpass (-) filter functions too. from our point of view this is the most flexible solution that enables e.g. these functions:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* lowpass: the audio signal is fed to the lp input, hp level control is set to zero, lp level control is set to the desired level\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* highpass: the audio signal is fed to the

polarizer control)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* lowpass\/highpass mix with one audio signal: the audio signal is fed to the lp input, lp and hp level controls are set to the

range of the hp level control) and no or little distortion only one obtains ~ a notch filter (the \"~\" indicates that the notch is far from beeing perfect, the attenuation in the passband is not as good as for other filters of the a-100 system)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* special setting 2: if the level controls for lp and hp are set in a way that both levels are identical with the opposite polarity (i.e. - range of the hp level control) and no or little distortion only one obtains ~ a bandpass filter (the \"~\" indicates that even the bandpass is far from beeing perfect, there is a significant feedthrough of frequencies below and above the center frequency.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* remark for settings 1 and 2: the original ms20 circuit was not planned for notch or bandpass applications. the ~notch and ~bandpass filters should be treated as a free bonus and have the disadvantages mentioned above. the reason is that the lowpass has a 12db\/octave slope and the highpass 6db\/octave. this leads to phase relations that do not allow a \"perfect\" bandpass and notch simply by adding\/subtracting signals as for other filter designs (for insiders: there remains always a 90 degree phase shift). for better notches and bandpasses other a-100 filters should be used - or two a-106-1 patched in series (bandpass) or parallel (notch) with suitable frequency settings.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e* lowpass and highpass with two different audio signals: the two audio signals are fed to the lp input resp. hp input, the level controls for lp and hp are set to the desired levels. for the +\/- control of the hp input it is essential in this case if the two input signals are phase correlated (e.g. two different outputs of the same vco or vco output and a frequency divided signal derived from this vco) or there is no fixed phase correlation between the two signals (e.g. two different vcos). in the first case the the - and + range of the hp control leads to different filter results. in the second case there is no difference if the + or - range of the hp control is used.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethis design allows even some very special functions: it is e.g. possible to adjust the controls so that the lp signal does not distort but the hp share does (or the other way round) - alternatively with the same or opposite polarity compared to the lp signal. for this the lp level has to be set to a small value so that the signal does not distort. the hp level control has to be set to a higher value (in the + or - range) so that the hp share will distort.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe variety of controls allows a lot of functions that are not available for any other filter we know.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eduring the a-106-1 development we found also that it might be useful to add controls not available in the original ms20 filters. in the original circuit the filter output level is limited to about +\/- 0.7v by two antiparallel diodes across the output\/resonance amplifier. by chance we discovered that removing one or both diodes leads to noticeable different behaviour of the filter. moreover we added two rotary controls cl+ and cl- to adjust the effect of each limiting diode (from original ms20 behaviour, i.e. fully active limiting diodes, to no limiting effect). the independent control for each diode allows asymmetrical limiting\/amplification that causes a completely new and sometimes very strange behaviour. one of the main effects of the asymmetrical limiting is that in self-oscillation the filter does not generate a sine wave but short pulses if only one of the limiting diodes is activated. another effect is that a higher output of the filter can be obtained (limited to about +\/- 0.7v for the original ms20 circuit). in addition dirty noise effects appear at certain combinations of the control settings for resonance, cl+, cl- and input level. the controls cl+, cl-, resonance, lp level and hp level have be looked at always in a common context: if the input levels are small the cl+ and cl- controls will have no effect as the signal does not distort at all. increasing the resonance also increases the audio level and the cl+\/cl- controls may now have an effect without changing the input level! same applies if the resonance control remains unchanged but the input level is increases. now the cl+ or cl- control will have an effect as the level reaches the clipping thresholds. increasing the audio level does also may suppress the resonance if distortion becomes extreme. the \"teamwork\" of the five controls is very complex and has to be learned by doing and hearing\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe audio inputs are very sensitive to allow even extrem

feedback loop. this allows to insert other a-100 modules into the resonance circuit. the standard application is to insert a vca for voltage controlled resonance. but even other modules - e.g. waveshaper, divider, phaser, distortion, pll, wave multiplier, spring reverb, ring modulator, frequency shifter ony any other audio processing module - can be inserted to obtain sounds you have never heard before.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eon top of this the module is equipped with two frequency cv inputs. one is carried out as a polarizer. this means that effect of the external cv (e.g. envelope from an adsr a-140 or a-141) to the filter frequency is positive (+ range) or negative (- range). especially when the filter is moved from lp to hp it might be useful to invert the polarity of the envelope cv. we also have to mention that the frequency response if far from 1v\/oct but rather non-linear.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eto obtain the filter section of the original ms20 two a-106-1 have to be patched in series (one in lp mode, the other in hp

academic sense: the control scale is non-linear. with self-oscillation all sorts of waveforms except sine are generated. with high distortion and resonance settings a lot of roaring\/rattling\/noise or other unpredictible sounds may appear. high distortion\/level may \"kill\" the resonance at certain settings. the filter has a significant control voltage feedthrough. the \"bandpass\" is not a real band pass as a considerable share of all frequencies passes through. the notch filter does attenuate only about 50% at the center frequency - and many more. but the a-106-1 has a lot of character - much more than any other filter of the a-100. it is a very strange and awesome filter - somehow exactly the contrast to the a-108, which is a very smooth, warm and predictable filter. the a-106-1 is definitely not the right choice for \"moogish\" and \"civilized\" sounds but for extreme, exceptional and experimental sounds - this is why we call the module \"x-filter\" to avoid troubles with the korg company who is the owner of the term \"ms20\". if you want to know more technical details please look at the a-101-1 technical details. in this document the basics of the a-101-1 (steiner) and a-106-1 (ms20) filters are described.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eincluded options: for the hp input control can be chosen if the polarizer is active or if a normal attenuator is available. for some applications it might be useful to have the level controls of lp and lp work in the same way (e.g. to obtain the same level for both inputs). with a jumper on the pc board the type of hp level control can be chosen. the cl+ and cl- parameters are prepared to be controlled by external vactrols. two pin headers are used to establish a connection to the universal vactrol module that is still under development. this will allow voltage control of the cl+ and cl- parameter.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eapplication

The frequency or pitch of the VCO is determined by the position of the octave (Range) switch and tuning (Tune) knob, and by the voltage present at the CV inputs. Frequency modulation (FM) of the VCO is therefore a possibility. Footage (the octave of the fundamental) is set by the Range control in five steps, and Fine tuning controlled by the Tune knob.

The term \"quadrature\" means in this connection that the oscillator outputs sine and cosine waveforms simultaneously. The term \"Thru-Zero\" means that even \"negative\" frequencies are generated. But this a bit a misleading term as negative frequencies do not really exist. \"Negative\" means in this connection simply that the sine\/cosine waves will stop when the linear control voltage reaches 0V and continue with the opposite direction as the linear control voltage becomes negative and vice versa.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe module has two control sections: linear and a exponential. The exponential section consists of the XTune control, the 1V\/Oct input and the XFM input with the corresponding attenuator XFM. The exponential control voltage is the sum of these three voltages. The linear section consists of the LFrq control and the LFM input with the corresponding attenuator LFM. The linear control voltage is the sum of these two voltages. A dual color LED is used to display the polarity of the linear control voltage (red = positive, yellow = negative). The pitch of the sine\/cosine outputs is determined by the control voltages of both sections. The linear section is used to control the pitch in a linear manner. When the LFrq control (LFrq means Linear Frequency Control) is fully CW the module works like a normal Quadrature VCO (e.g. like the A-143-9) and the LED lights red (red = positive). The pitch is then controlled by the exponential section with the manual Tune control XTune and the exponential frequency control inputs 1V\/Oct and XFM. 1V\/Oct is used to control the pitch by a 1V\/Oct CV source (e.g. sequencer or Midi\/USB-to-CV interface). XFM is used to apply an exponential frequency modulation with adjustable depth (e.g. from an LFO or another VCO). As the LFrq control is turned counterclockwise starting from the fully CW position the frequency is lowered in a linear manner until the sine\/cosine waves (nearly) stops at the center position of LFrq (provided that no LFM signal is present). As the LFrq control is moved from the center towards the CCW position the wave starts again but into reverse direction and the LED turns yellow. When the fully CCW position of LFrq is reached the module works again like a normal Quadrature VCO. But much more exciting is the usage of the LFM input to modify the linear control voltage by an external control voltage (typically another sine VCO like a second A-110-4 - but even normal VCOs can be used). Linear modulation by another oscillator using the thru zero feature generates audio spectra than cannot be obtained from an oscillator without the thru zero function. The reason is that a \"normal\" VCO will simply stop as the linear control voltage becomes zero or negative. But a thru zero VCO will start again with \"negative\" frequencies as the the linear control voltage becomes negative.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe main advantage of the A-110-4 compared to other Thru Zero VCOs is that the design uses a sine\/cosine core.

In this case the external voltage is fed into the external CV jack (with integrated switch to turn off the LFO signal) and the amplitude control of the LFO affects the level of the external CV signal. Each filter is equipped with the following controls: LFO frequency, LFO\/external CV amplitude, filter frequency, filter resonance and filter amplitude. In addition to the mix output for all three filters each filter has a separate audio output. The original audio signal can be added to the triple filter mix signal with a separate control. All of the 3 filters share a common audio input with attenuator. The filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds - if desired.

contrast to frequency multiplication e.g. with the pll a-196). the a-137 works as a kind of \"inverse low pass filter\", i.e. it adds a lot of harmonics to a signal that contains none or only a few harmonics (e.g. sine or triangle waveform). in contrast to that a low pass filter (e.g. a-120) removes harmonics from a signal that contains a lot of harmonics (e.g. saw or rectangle waveform). consequently the best results are obtained in combination with input signals poor in harmonics (e.g. sine or triangle). the a-137 can be used with signals rich in harmonics too (e.g. saw) but the

manual and ext. cv) the upper and lower clipping levels of the wave folder units are controlled. the harmonics parameter (manual and ext. cv) adds some harmonic content by sharpening the waveform edges and adding overshoot peaks. it works a little bit like the resonance control of a vcf. the module is fully dc coupled, i.e. even control signal can be processed with the modules.\u003cbr\u003e\u003cbr\u003e as it is a little bit difficult to describe the parameters only by words we have some pictures and audio examples available that explain the function of the module

module are altered. the signal is processed by a vca and 4 so-called wave folding stages. from the parameters folding level and symmetry the upper and folding level is derived for each stage. at the clipping levels the signal is \"folded back\", i.e. the direction is inverted or the signal is \"reflected\" at the clipping line. the working principle of the first folding stage. as the module contains 4 folding stages up to 8 foldings are possible (4 at the upper and 4 at the lower clipping level).\u003cbr\u003e\u003cbr\u003e the incoming signal of each stage is folded back as soon as the signal level goes beyond the upper clipping level resp. is folded up as soon is goes below the lower clipping level (a-136 users will know this function, indeed the a-137 includes 4 stages similar to a-136 but with some fixed settings). as mentioned above upper and lower clipping level are controlled by the folding level and symmetry controls (both manual and cv controlled). from our point of view these parameters are easier to use than upper and lower clipping level. the internal upper and lower clipping levels are derived by adding resp. subtracting the folding level and symmetry voltages. the vca setting (multiples control) defines the number of wave multiplications or foldings as the multiplications depend upon the level that appears at the folding stages. smaller levels lead to less multiples, higher levels cause more multiples as the folded output signal of the preceeding stage has sufficient level for a subsequent folding in the next stage.\u003cbr\u003e\u003cbr\u003e the harmonics control sharpens the waveform slopes and adds some overshoot at the edges - a little bit like the resonance control of a filter. internally the harmonics feature is realized by an additional

relation between both signals one obtains a phase shifted sawtooth. the left picture shows the incoming sawtooth wave on top. the two horizontal dashed lines (blue and orange) indicate two different

four shifted signals and in addition four rectangle outputs. a corresponding breakout module with eight sockets is in the planning stage and will be released provided that there are sufficient

an integer number in the range 1...6 that can be adjusted with the manual control (man n) and an external control voltage cvn with attenuator. whenever the rising edge of the input clock signal (clk in) appears a new random voltage is generated at the n+1 resp. 2n output. the n+1 output is capable to generate n+1 different voltage levels (or states), the 2n output up to 2n different states. if for example n is set to 4 the n+1 output generates up to 5, the 2n output 16 different states. the voltage steps of the 2n output are adjusted to 1\/12 v in the factory. consequently exact semitones can be obtained in combination with a vco. the voltage steps of the n+1 output are adjusted to 1.0 v in the factory corresponding to octave intervals in combination with a vco. for each output a

digital pseudo random generators that work with shift registers and digital feedback via exor gates (the same principle as used in the digital noise module a-117). the digital output voltages of the shift registers are added up with resistors to obtain variable stepped analog voltages. for the n+1 output all resistors have the same value, the 2n output uses resistors in ratios of 1:2:4:8:16:32. consequently the n+1 output has less different states available than the 2n output. in addition the digital shift register outputs are gated dependent on the current n voltage (sum of manual control + external cv) by which the number of possible states can be reduced. in contrast to the a-117 the shift registers are not clocked by an internal oscillator but by the external clock input clk

The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. The multiplied clock signal is available at the socket Clock Out. According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. With 0V CV no clock output is generated. This state is indicated by \"all LEDs off\". With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. Nine LEDs are used to show the currently selected multiplying factor. In addition two LEDs are used to display the incoming and outgoing clock signal.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eA manual control is used to adjust the clock multiplication factor manually without the need of an external control voltage. The voltage generated by this control (\"Manual\") is normalled to the CV In socket. As long as no plug is inserted into the CV In socket the clock multiplication factor is adjusted by means of the manual control knob and displayed by the LEDs. For dynamic applications (like the ratcheting function described below) the manually generated CV is overwritten by the external CV which has to be fed into the CV In socket.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe module can be used for all kind of clock multiplying applications. One important example is the generation of so-called ratcheting sequences. The band Tangerine Dream is famous for this kind of sequences. A normal sequencer generates only one gate signal per step. A ratcheting sequence may have also more than one gate pulses per step. This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eTechnical note: Due to the nature of clock multiplying it takes a few input clock pulses until the clock output is stable. One has to average a few input clock pulses to generate the multiplied clock output signal. Even when the input clock frequency changes it will take a few cycles until the output clock signal is correct as the module cannot forsee the future of the clock input signal. The generated clock output signal is derived from the last few cycles of the clock input signal. Consequently the module should be driven only by a clock signal with constant or slowly changing frequency.\u003c\/span\u003e\u003c\/p\u003e","brand":"Doepfer","offers":[{"title":"Default

- A-196: Phase Locked Loop (PLL)","description":"\u003cp\u003e\u003cstrong\u003eManufacturer Description\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003eModule a-196 contains a so-called phase locked loop (pll). the basic pll system is shown in the sketch at the bottom of this page. a pll consists of three parts: voltage-controlled oscillator (vco), phase comparator (pc), and low-pass filter (lpf). all parts are normally connected to form a closed-loop frequency-feedback system.\u003cbr\u003e\u003cbr\u003e this is how a pll works: the output of the internal vco (linear cv control, rectangle output) is compared with an external signal (e.g. the rectangle output of a a-110 vco) in the so-called phase comparator (pc). the output of the phase comparator is a digital signal (low\/high\/tristate) that indicates if the frequency resp. phase difference of the two input signals is negative, zero or positive. the output of the phase comparator is processed by a low pass filter (lpf) to generate a smooth voltage that is used to control the frequency of the internal vco. the 3 units vco, pc and lpf form a feedback loop that works like this: the control voltage (output of the lpf) increases as long as the external frequency is higher than the frequency of the internal vco und stops increasing when both frequencies become identical. the control voltage decreases as long as the external frequency is lower than the frequency of the internal vco und stops decreasing when both frequencies become identical.\u003cbr\u003e\u003cbr\u003e but there are some stumbling blocks: different types of phase comparators with advantages and disadvantages an be made. some phase comparators e.g. even lock at harmonics, i.e. if the two frequencies to be compared are integer multiples. but for some applications this can be used to create interesting effects. the a-196 contains 3 different types of phase comparators: pc1 is a simple exclusive or, that even locks at harmonics. pc2 is a so-called rs flipflop and pc3 a more complex digital memory network. the user can select one of the three phase comparators with a 3-position switch. when pc2 is used a led displays the \"locked\" state, i.e. when the frequency of the internal vco is identical to the external frequency.\u003cbr\u003e\u003cbr\u003e special attention has to be directed to the frequency of the lpf. to obtain a smooth control voltage for the vco the frequency of the lpf has to be much smaller than the lowest frequency of the internal or external audio signal. otherwise the frequency of the internal vco will jitter or wobble around the correct frequency. but for special effects this frequency jitter can be used intentionally. example: frequencies in the range 50hz...1khz have to be processed with the pll. therefore the frequency of the lpf has to be about 10hz or even less. such a low frequency of the lpf causes a noticeable slew of the internal vco. when the frequency of the external signal jumps e.g. between 500hz and 1khz it takes about 0.1 second until the internal vco reaches the new frequency (like portamento). so one has to find a compromise between frequency jitter and portamento. but these remarks are valid only for the \"ideal\" working pll. as the a-196 is used in a musical enviroment the \"problems\" and disadvantages with jitter and slew time lead to additional musical applications like portamento effects, wobbling frequencies or harmonic locking according to the type of frequency comparator and time constant of the pll low pass filter. instead of the internal manually controlled low pass filter the voltage controlled slew limiter a-171 can be used to obtain voltage control of this parameter. normal audio filters (e.g. a-120, a-121) cannot be used for this job as the minimum frequency is to high (down to a few hz or even less necessary) and the signal has to be dc coupled due to the low frequencies. audio filters are normally ac coupled.\u003cbr\u003e\u003cbr\u003e another very important application of a pll is frequency multiplication in combination with an external frequency divider. for this the output of the pll-vco is processed through an external frequency divider (e.g. a-163, a-160, a-161, a-115) before it is fed to in1 of the phase comparator. in this case the frequency of the pll-vco will be a multiple of the master frequency. e.g if the the a-163 is used and adjusted to dividing factor 5 the frequency of the pll-vco will be 5 times the frequency of the master vco. consequently frequency division (a-163) leads to frequency multiplication with the pll circuit. in combination with the pll low pass frequency several effects can be realized (frequency multiplication with portamento or wobbling). the frequency multiplication can even be used to drive a graphic vco. if your graphic vco e.g. has 8 steps (e.g. a-155) and you use a frequency divider with factor 8 in the pll feedback the output of the graphic vco has the same frequency as the master vco. another application is the generation of pseudo-harmonics (not real harmonics as only rectangle waves are available) or clock generation for switched-capacitor filters.\u003cbr\u003e\u003cbr\u003e the pll components are available as separate building blocks in the a-196 module. the standard pll patch is realized by means of normalized sockets. but it is also possible to use each component separately. e.g. the vco can be used as a simple vco with linear control input and rectangle output. for this an external voltage has to be fed into the cv input socket. the vco has two controls: offset and range (switch). as the vco has a linear control input the frequency will go down to zero (i.e. the vco stops) if the input cv is 0v. the offset control is used to adjust the lowest frequency (i.e. the frequency for cv = 0v). the range switch is used to switch between 3 frequency ranges. the position of the switch defines the max. available frequency (detailed specifications will follow).\u003cbr\u003e\u003cbr\u003e for other treatments of the phase comparator output (e.g. with an external voltage controlled filter or any other processing module) the output of the phase comparator is available. same applies to the lpf output and input 1 of the phase comparator.\u003cbr\u003e\u003cbr\u003e it has to be pointed out that the a-196 is a very experimental module and its functions cannot be described straight forward as for other modules. rather the user should try out the possibilities by trial and error.\u003cbr\u003e\u003cbr\u003e applications: frequency multiplication, special sound effects, generation of clock signals for graphic vco (high speed vco, e.g. for a-155 as graphic vco), clocked audio delays or switched-capacitor filter.\u003cbr\u003e best results are obtained with pc2 and high range of the a-196 vco. the lowpass control of the a-196 is used to adjust the glide time resp. the frequency jitter. the frequency divider module a-163 is used to adjust the frequency multiplication (manually or by means of a control voltage).\u003cbr\u003e\u003cbr\u003e some parameters are changed during the sequency manually (e.g. pulsewidth of rectangle output vcoa, lowpass frequency of the pll).\u003cbr\u003e\u003cbr\u003e this module has a maximum current draw of 30ma. it requires 8 te\/hp
