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

Trimmer 8 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 8 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.
