Description

Manufacturer Description:

Module a-189-1 is the first derivative of the universal ad/da module. it offers several voltage controlled algorithmic functions like voltage controlled bit crunching, bit shifting (with/without carry over), bit exchange, rectifying, absolute value and calculating operations like addition, subtraction, multiplication or division.

the module has two control units both with manual control and cv input with attenuator:

one for the algorithmic function according to the selected mode (e.g. number of shifted bits): bc and bc cv
and one for the sampling rate (sr and sr cv).

the signal input is equipped with an attenuator. as the module is dc coupled even control voltages can be processed.

the mode (e.g. bit crunching, bit shifting, bit exchange) is selected by a 16-position rotary switch:

switch position	function	remark
1	bit crushing	bc controls the number of bits (bit reduction)
2	and	signal and bc
3	or	signal or bc
4	xor	signal xor bc
5	bit shift right	bc controls the number of bit shifts
6	bit shift left	bc controls the number of bit shifts
7	multiplication	signal x bc
8	compare & complement	if signal > bc then output = bit complement of the input signal, otherwise unchanged
9	compare & absolute	if signal > bc then output = absolute value of the input signal, otherwise unchanged
10	addition	output = signal + bc (with overflow/clipping)
11	addition with bc swap	same as 10 but with nibble swap of bc (nibble = half byte, i.e. four bits)
12	short delay 1 with dynamic normalization	bc controls the length of the delay memory
13	short delay 2	same as 12 but different length/feedback
14	short delay 3	same as 12 but different length/feedback
15	short delay 4	same as 12 but different length/feedback
16	four stages fir filter	bc controls the filter coefficient

this module has a maximum current draw of 50ma. it requires 8 hp/te worth of space to fit in a eurorack frame.
