The 333 is a summing and distribution module for Eurorack modular systems.

It consists of three identical sections—red, yellow, and green—each featuring a three-input summing amplifier with three independently buffered outputs.

Directly derived from the CGM creative mixer series, the sum section is DC coupled, allowing the summing of control voltages as well as audio signals.

With extremely low tolerance in both the sum and output sections, it is also suitable for summing quantized voltages like those from the quantized outputs of the SAPEL.

If CVs or audio signals are particularly strong, the 6dB attenuator can help reduce the incoming signals by exactly 50%.

The red and yellow outputs are also normalized to the first jack socket of the yellow and green inputs: this way, the module can also function as a 1-to-9 buffered multiple.
