A-149-2 is an extension module for A-149-1. It makes available 8 digital random voltages (i.e. only low/high states like a gate signal). The outputs are controlled by the “Quantized Random Voltages” section of the assigned A-149-1 and correspond to the 8 digital outputs of the shift register that is used to generate the Quantized Random Voltages (for detailes please refer to the A-149-1description). As the alteration of the A-149-2 outputs is clock controlled by the Clk In of the “Quantized Random Voltages” section of the A-149-1 the A-149-2 can be used to create random rhythmical sequences.
The A-149-2 requires the A-149-1 and has to be mounted directly to the left or right of the A-149-1 as an internal ribbon cable connection has to be established between A-149-1 and A-149-2.

A very detailed description of the functions of the random voltages and their application can be found in Allen Strange’s excellent book “Electronic music – systems, techniques and controls” from page 82 (refer to A-100 Further Reading).
