ADDAC814 6x6 Stereo Matrix Mixer

ADDAC System

6x6 stereo matrix mixer, DC-coupled, expandable to larger configurations. Each knob controls the volume at one matrix crosspoint routing a stereo input to a stereo output. All left input channels are normalled to the right inputs. Ships as two modules: ADDAC814A (Jacks) and ADDAC814B (Master Controls).293

Capabilities 3

DC Coupleddc-coupled
All circuitry is DC-coupled; can mix audio or CV signals at all inputs and outputs.293
Matrix Feedback Diagonalmatrix-feedback-diagonal
Crosspoints 1A, 2B, 3C, 4D, 5E, 6F (cream-colored on the panel) are the diagonals. Wiring Output N back into Input N externally creates a feedback loop scaled by that crosspoint.293
Matrix Mixermatrix-mixer
6×6 stereo (12 mono in / 12 mono out) with 36 stereo crosspoint knobs. Per-jack Synth/Line jumpers on the rear of the ADDAC814B master controls module.293

Jacks 24 (12 in / 12 out)
