MAKING CONNECTIONS/APPLYING POWER
To connect the TRIO pedal:
1. Turn down the guitar amplifier’s master volume control. If connecting to a PA system, bring the fader of the
mixer channel to which you will be connecting the TRIO all the way down.
2. Make all audio connections to the TRIO as shown in 'Connection Diagrams' on page 7.
3. Connect the appropriate Harman power adapter (included) to the Power Adapter Input jack and connect
the other end to an available AC outlet.
4. Strum your guitar and gradually increase your amplifier’s master volume control until the desired level is
achieved. If connecting to a PA system, while strumming slowly, bring up the fader on the mixer channel to
which you have connected the TRIO. Consult your mixer manufacturer's documentation for recommended
channel gain and fader setup information.
