A-127 Break Out Module

This expansion module offers the following additional functions to the A-127:  notch filter for each sub-unit,  separate outputs for lowpass, highpass, bandpass and notch for each sub-unit and separate audio input with attenuator for each sub-unit


The breakout module allows the separate use of each of the three A-127 filters. In addition the filters can be patched parallel or serial. Especially the serial connection of three notches generates very complex phasing-like structures. For parallel filter connection the existing mixer of the main module may be used or an external mixer. For serial connection the filters are patched in the desired sequence at the breakout module. A jumper is used to define the filter type for each sub-unit for the mix unit of the main module.


NOTE: The breakout module can be used without modification only in combination with the new version of the A-127 (pcb printing "Version 4"). Only the new version has the expansion connector available, that is required to connect the breakout module without soldering.

Older versions of the A-127 (versions 1, 2 and 3) require soldering.
