Catalyst Audio - Model 106 6-Channel Mixer


Catalyst Audio’s Model 106 is based on the mixer of Buchla’s 100 series. The module features six input channels with level potentiometers and four (sub) outputs. Thanks to its transistor circuitry and low headroom, the Model 106 has a very distinctive sound. High input levels lead to warm, nonlinear distortion. However, signals are never getting destroyed. Rather, the module adds some beefy analog flavor.



Model 106 comes equipped with six inputs. Each channel features a level potentiometer, high settings lead to nonlinear distortion. On the output side, there are four connectors. In detail, two sub outputs for channel one to three and four to six as well as two main outs with reversed polarity are available.
Hint: With daisy-chaining two channels via the sub-outputs or creating feedback loops, you can push the nonlinear distortion even further. The sound will always stay friendly and musical, though.

All modules of the Catalyst Audio 100 series were A/B tested with an original 100 series system. The analog circuits feature a discrete, transistor based design. Hand-picked components guarantee high performance, durability and excellent sound. Audio and CV levels have been adjusted to be compatible with the Eurorack standard. Op-amps were used for this task. The components can be removed from the signal flow via jumpers.
