7-Channel Amplifier-Attenuator

Low-noise AC-coupled Attenuation or Amplification up to 40dB for Hexaphonic or Polyphonic Processing


The 7-Channel Amplifier-Attenuator can be ordered with one of three gain options: 20 dB, 30 dB, 40 dB.
Gain controls allow you to adjust the gain from zero to full-scale in the amplified string outputs.
Typical application is for Roland GK guitar signals, with the individual hex pickup signals processed by the top 6-channel group and the passive pickup amplified by the 7th channel.
Ideal for multi-channel guitar or bass single-string processing.


  • Precision metal-film resistors for close channel gain matching.
  • Low-noise audio op-amps for optimal AC performance.
  • Selectable gain range (1x or 10x, 30x, 100x) for output on back of the module.
  • Adjustable gain or attenuation to zero within each selected gain range.
  • Pairs well with 13-Pin Input Breakout, Nexus Breakout, Hex VU Meter, Hex Fuzz, Hex VCF, Hex VCA, 13-pin Output Breakout.
