Mono mode allows you to drive the left speaker by one power amplifier and the right speaker by another power amplifier.
Power Amplifiers must be controlled by a product in pre-amp (variable output) mode. Otherwise you risk maximum volume output which may damage your speakers.
Unbalanced connection in mono mode
1.The diagram below shows how to drive a pair of MXW70's connected to a MXN10 using an unbalanced connection.
2. In the Mono mode, only 8ohm is supported and the red terminal of the “Right” is the negative output.
3. Turn on the Pre-Amp mode in the StreamMagic app, to ensure the volume increases/decreases in sync.
4. Set the Mode switch in Mono mode and ensure that the unbalanced switch has been selected.
