Change like these:
- Input: XLR * 2
- three stops switch: high gain – low gain – Mono/Mono
- Output: the left channel 3-pin XLR will be the Mono/Mono output, the right channel output will shut down when working in Mono/Mono mode.
- need two units for Mono/Mono mode.
- work same as a normal Formula S, single end stereo amp with XLR input
