The CUBE Street II does not have a built-in wireless microphone receiver. To use a wireless microphone system, connect the output jack of the wireless receiver to the MIC/INSTRUMENT jack on the CUBE Street II.
Check the following point before connecting:
The MIC/INSTRUMENT jack has two input level settings. Set the [SELECT] switch to match the output level of the wireless receiver: MIC setting (-40 dBu) or INST setting (-20 dBu).
