2nd Version of our 4ch Stereo Mixer is here!

(check the older version here)
This mixer can be used as a summing box for a variety of signal types. It can take up to 4 stereo signals and combine them into a single stereo output, plus a mono out (sum L + R).
It features high-impedance TRS inputs that can be driven by instruments (guitar, bass etc) or line level signals as well. The circuit makes use of low distortion, low noise op amps and each input has a volume knob that goes from mute up to +6dB gain.
Two outputs are available: One is a full stereo (TRS) output and the other is a mono-AUX (TS) output which offers the mono sum for the stereo signals (L+R). The TRS and the TS outputs are totally independent and can be used simultaneously.
Two additions have been made in comparison to the previous version:
- Inputs 2 & 3 are equipped with Stereo/Mono selection switches in order to help you expand a mono signal to stereo. This way you can connect a mono (TS) jack to these inputs and have the mono signal appear in both L & R channels in the output.
- Inputs 2 & 3 are equipped with Stereo/Mono selection switches in order to help you expand a mono signal to stereo. This way you can connect a mono (TS) jack to these inputs and have the mono signal appear in both L & R channels in the output.
- Inputs 3 & 4 are equipped with Phase Reverse switches to help you avoid any phasing problems when mixing signals and also to give you more options to experiment.
The mixer works with standard pedal power supplies. Voltage range: 9-24 V. Using voltage higher than 9V will give you more headroom. The mixer is always on when power is connected (external LED is lit when ON)
