LIVE CONNECTION EXAMPLE The diagram shown below is a possible connection scheme for a live application. Connect instruments and microphones to the appropriate input jacks. If condenser microphones requiring phantom power are being used, press the Phantom Power switch in. Aux 2 is used as a monitor output because the signal is taken before the channel fader - this is typically a monitor send. Aux 1 may be connected to a signal processor as shown on page 4.
