QUICK START
TURN ON THE AMP
Check the MASTER volume, GAIN and channel VOLUME potentiometers are completely closed or the MUTE is
activated.
Connect the power cable to mains and switch on the amp.
If a ground noise (hum at 50-60Hz) occurs, ip the ground lift switch (GND LIFT) on the rear panel.
CONNECTIONS
Connect a microphones to the XLR or instruments to the ¼”jack sockets. Remember to activate the P24 phantom
power on the XLR when using condenser microphones and DYN P48 contact microphones or the 10V on the
¼”jacks when using STAT pickups or other electrostatic microphones.
LEVELS SET UP
Playing (or singing) loud, turn the GAIN up until the OL red LED starts to blink, from there turn it back down a
little. Now open the MASTER between 0% and 50% nally adjust CHANNEL VOLUME as needed.
OTHER FEATURES
Once the levels are properly set, you can shape your sound with the EQ and the WARM lter (on ch. 1) or cut
the selectable 150 Hz or 240 Hz with the RESON notch lter (on ch.2) and set the amount of REVERB you want
on each channel and its return on the MASTER. The LOW CUT button will high pass the signal to the speaker.
EXTERNAL EFFECTS
You can connect external effect on the MASTER (affecting both channels) using a Y-cable: connect the stereo
jack to the INSERT socket and the two mono jacks to the input and output of the external pedal.
