Created page with "Settings that can be controlled directly: - Gain - Pad - Phantom - Stage 16 LEDs ## Devices - The following devices are located in `/sys/bus/devices`. - The `_en` extension..."

New page

Settings that can be controlled directly:
- Gain
- Pad
- Phantom
- Stage 16 LEDs

## Devices

- The following devices are located in `/sys/bus/devices`.
- The `_en` extension represents "enable".

**(\*)** Each directory controls a bank of 4 channels. The directory 0 or 4: Ch 8-5, 1 or 5: Ch 4-1, 2: Ch 12-9 3: Ch 16-13). E.g., `spi1` channel #1 == `spi1.1/ch3_*`. **NOTE:** Changing file values directly will not be reflected in the VENUE UI.

## Discovery

Dumps the values of the IO board devices in /sys/bus/spi/devices.
