How to Bridge the Zen v4

[Super_BQ]

Greetings,

Is there a particular way to bridge 2 zen v4 PCB for double the power in single ended? I would like to make this modification between balanced XLR to single ended bridge by a flick of a switch.

I originally installed a switch thinking that I would need to switch between XLR balanced (1 channel) to RCA single ended (2 channel). But really, all connections in single ended stereo can be kept the same with 2 PCBs while for balanced, you connect the speakers to the different polarity (on the speaker posts). - no switch required. However, it's not dummy proof as one could try to hook both RCA & XLR at the same time
