Full Description

The user manual for the Optomix, containing technical data and instructions for use, can be accessed here.

Controls & I/Os

• Channel 1 Signal Input: Direct-coupled signal input capable of accepting audio or control signals. Range of up to 10Vpp
• Channel 1 Damp CV Input: CV input for the channel's damping parameter, now capable of accepting audio or control signals. Normalized to +8V so that with nothing patched, the channel 1 damp combo pot operates as a manual control for the parameter. Range 0V - 8V
• Channel 1 Control Input: Direct-coupled, highly sensitive CV input for the channels vactrol VCA. Normalized to +8V so that with nothing patched, the channel 1 control combo pot operates as a level control for the offset. Range 0V - 8V
• Channel 1 Damp Combo Pot: Unipolar attenuator for the damp CV input. With nothing patched to the damp CV input, operates as a manual control for the damp parameter
• Channel 1 Combo Pot: Unipolar attenuator for the control signal input. With nothing patched to the channel 1 control signal input, operates as a level control for the offset
• Channel 1 Signal Out: Output of the signal applied to the channel 2 input, as processed by the LPG. 10Vpp (depending upon settings and source material)
• Channel 1 Strike Input: Gate input for striking or plucking the vactol. Expects 8V gate
• Channel 2 Signal Input: Direct-coupled signal input capable of accepting audio or control signals. Range of up to 10Vpp
• Channel 2 Control Signal Input: Direct-coupled, highly sensitive CV input for channel 2's vactrol VCA. Normalized to +8V so that with nothing patched, the channel 2 combo pot operates as a manual control for the offset. Range 0V - 8V
• Channel 2 Damp CV Input: Input for channel 2's damp parameter, now capable of receiving audio or control signals. Normalized to +8V so that with nothing patched, the channel 2 damp combo pot operates as a manual control for the parameter. Range 0V - 8V
• Channel 2 Damp Combo Pot: Unipolar attenuator for the channel 2 damp CV input, with nothing patched to the channel 2 damp CV input, operates as a manual control for the parameter
• Channel 2 Control Combo Pot: Unipolar attenuator for channel 2 control signal input. With nothing patched to the channel 2 control signal input, operates as a manual level control for the offset
• Channel 2 Signal Output: Direct-coupled output of the signal applied to the channel 2 input, as processed by the LPG. 10Vpp (depending upon gate settings and source material)
• Channel 2 Strike Input: Gate input for striking or plucking the channel 2 control vactrol. Expects 8V gate
• Auxillary Input: Direct-coupled signal input to the Sum circuit, allowing for the chaining of multiple Optomix and modDemix units to create larger mixes. Capable of accepting audio or control signals up to 10Vpp
• Sum Out: The sum or mix of all signals processed by the Optomix is output at this jack. 10Vpp (depending upon settings and source material)

Features

• Damp circuit updated to accept audio as well as CV, allowing for patching side-chain compression
• Strike input allows use of gate signal to trigger low-pass gate circuit, plucking or striking the vactrol
• Damp and Strike parameters combine to allow for easy programming of percussive sounds (sharp attack with voltage-controlled decay
• Normalization of a positive offset to the channel inputs allows for level-shifting of CV, envelope generator, and even subtle non-symmetrical clipping of signals
• Summing stage with an auxillary input allows for chaining of multiple units creating larger mixes
• Direct coupled, process audio or control signals
• Utilizes 4 vactrols
• Pairs perfectly with modDemix and MATHS modules
