LjunggrenAudio RYO ​Vertmix:
a 3-channel attenuvering mixer in 6hp .


Vertmix is out of production, new version coming but we don't know when.
It will have surface mounted resistors and ceramic capacitors in 0805 size. The rest of the components will be thru hole.

- 3-channel attenuverting high precision mixer/attenuator/inverter.
- Works as 3 channel mixer, 1 attenuvertor + 2 channel mixer or 3 attenuvertors.
- All analogue circuitry.
- Hi-fidelity signal chain with low noise opamps.
- High impedance inputs and buffered outputs.
- Slim 6HP footprint.
- Compact 35mm Depth (with power cable attached).
- Low power draw: 22mA+12V / 22mA -12V /no +5V required.
- Works for audio as well as CV.
- Fast responding CV inputs allow for complex modulation and modulating with audio signals.
- Sum mix output.
