A compact eight channel level control for both audio and DC-coupled control voltages for integration with SwitchMix™ or standalone use.

The Trimmer is much more than just a buffered attenuator. Each channel may be precisely calibrated between -10dB (÷3) to +10dB (x3) gain so that prior signal or CV losses may be compensated. Trimmer 8 may be inserted into the DB25 input or output connections of SwitchMix™ and may also incorporate phase inverting switches and/or a mixture of connectors with normalling.


Trimmer 2005EJ with polarity switching.


Trimmer has balanced or unbalanced compatible inputs and outputs, extending its use beyond synthesizer patching to other audio routing applications. It is suitable for interfacing DAW sound cards to a synthesizer and may be used for balanced to unbalanced or unbalanced to balanced conversions with level change.
