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 -

It contains three separate voltage controlled band pass filters. Each filter has it's own LFO (triangle waveform) with LED display and adjustable frequency and amplitude. Instead of the internal LFO an external control voltage may be used to control the filter frequency. 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. The frequency control range of the bandpass filters is about 40Hz...6kHz, the frequency range of the LFO's is about 0.02Hz...20Hz (= 1 min ... 1\/20 sec per cycle).\u003cbr\u003e\u003cbr\u003e Each of the three filters can used also as a 12dB low pass (with resonance control) instead of band pass.

request several functions of don buchla's  265\/266 (sou) modules that cannot be realized with existing a-100 modules. many functions of 265 and 266 sou can be realized with existing a-100 modules.

generated in different ways.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe \"quantized random voltages\" section has available 2 cv outputs: \"n+1 states\" and \"2n states\". n is 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 trimming potentiometer is available on the pc board that enables the user to select other voltage steps for the output in question.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eeven the \"stored random voltages\" section has 2 stepped cv outputs available: one with even voltage distribution of the max. 256 output states and second one with adjustable voltage distribution probability. the distribution probability is adjusted by a manual control (man d) and an external control voltage cvd with attenuator. with the control set fully counterclockwise most of the random voltages will be low magnitude but even medium and high magnitude voltages may appear but with smaller probability. as the control is turned to the right (or a positive control voltage appears at the cvd input) the distribution moves through medium to high magnitude voltage probability. the symbol at the lower jack socket shows this coherence graphically. the voltage range is 0...+5v for both outputs of the \"stored random voltages\" section. for each output a trimming potentiometer is available on the pc board that enables the user to select another voltage range for the output in question.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe a-149-1 can be extended by 8 random digital voltages with the a-149-2 digital random voltages

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 in.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ethe generation of the \"stored random voltages\" is similar but with different resistor values and more shift register outputs. in addition the random voltage is processed by a non-linear clipping unit with adjustable offset that allows to modify the distribution probability of the voltage levels appearing at the lower output.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eeven though the module is intended to generate slowly varying control voltages clock frequencies up to moderate audio range (about

This VCO's frequency range is about eight octaves (ca. 15Hz ... 8kHz). It can produce four waveforms simultaneously: rectangle, sawtooth, triangle, and sine wave (triangle and sine shapes are not perfect, see remark below). The output levels are typically 8Vpp for saw and rectangle, and 10Vpp for triangle and sine. 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 tune knob range is about +\/-1 semitone for older modules. Since about middle of 2015 the value has been increased to about+\/- 1\/2 octave.

The module is made of these sub-units:\u003cbr\u003e\u003cbr\u003e VCLFO: voltage controlled low frequency oscillator\u003cbr\u003e\u003cbr\u003e VCA: voltage controlled amplifier, switchable to voltage controlled polarizer\u003cbr\u003e\u003cbr\u003e VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato\/tremolo)\u003cbr\u003e\u003cbr\u003eLFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset\/Sync input. Triangle\/Sine and Rectangle are displayed by means of dual-color LEDs (probably red\/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.The CV control can be switched to attenuator or polarizer (\"CV Mode\" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the center position. In the center position CV has no effect and right from the center the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per periode) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the \"LFO CV\" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 \"Dummy\". JP7 has no function and is used only for \"parking\" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.\u003cbr\u003e\u003cbr\u003eVCA: This is a linear VCA that can be switched to \"normal\" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer (\"VCA Mode\" switch). In the \"normal\" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).\u003cbr\u003e\u003cbr\u003eThe VCA of the A-147-2 has three sockets available: \"In\" (signal input), \"Out\" (signal output) and \"CV\" (control voltage input). The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the \"VCA In\" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the \"VCA In\" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator\/attenuator A-183-2).\u003cbr\u003e\u003cbr\u003eAttack\/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter \"Delay\" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage (\"Delay CV\" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a unicolor LED (probably orange) and available at the \"Delay Out\" socket.\u003cbr\u003e\u003cbr\u003eThe manual Delay control ranges - without external \"Delay CV\" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the \"Delay CV\" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO) !\u003cbr\u003e\u003cbr\u003eThe Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the \"Delay Reset\" sockets resets the Delay output voltage to 0 V. \"Delay Out\" is normalled to the VCA CV input by means of the switching contact of the \"VCA CV\" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB\/Midi-to-CV\/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA. But the Delay sub-unit can be used also independently from the LFO and VCA, e.g. as a voltage controlled waveshaper or for other applications where a linear increasing signal with voltage controlled steepness is required.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications: \u003c\/strong\u003e\u003cbr\u003e Output level Triangle, Sine and Rectangle: about -4...+4V (symmetrical)\u003cbr\u003e Output level sawtooth: about 0...+8V (positive only)\u003cbr\u003e Frequency range without external CV: about 0,005Hz (about 3 minutes) ... 200Hz\u003cbr\u003e Frequency range in ultra low mode or external CV: about 1 hour period ... about 1kHz\u003cbr\u003e Trigger level for LFO Reset\/Delay Reset: about min. 6 Vpp (AC coupled, i.e. the voltage difference is essential)\u003cbr\u003e VCA CV\/amplification: 0....+5V for amplification 0...+1 (in VCA mode), 0...+5V for amplification -0,5...+0,5 (in polarizer mode)\u003cbr\u003e Delay range: about 5ms ... about 2 minutes\u003cbr\u003e\u003cbr\u003eWidth: 8 TE \/ 8 HP \/ 40.3 mm\u003cbr\u003eDepth: 55 mm (measured from the rear side of the front panel)\u003cbr\u003eCurrent: +60mA (+12V) \/ -40mA (-12V)\u003c\/p\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":8884422967343,"sku":"","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5199\/7743\/products\/a-147-2.jpg?v=1582834550"},{"product_id":"a-180-2v","title":"Doepfer - A-180-2V","description":"\u003cp\u003e\u003cb\u003eManufacturer Description\u003c\/b\u003e:\u003c\/p\u003e\n\u003cp\u003eModules A-180-1 and A-180-2 are simple multi-connectors.
