Quick Start
Power
To power the unit, connect the included 9V DC power supply to the jack labeled DC 9V on the back
panel. When running a 3
rd
party power supply, the Spectrum requires an isolated 9V DC power
source with a minimum of 165mA and a center-negative plug.
Warning: Using a non-Source Audio supply, especially an unregulated supply, could damage the unit.
Please be very cautious when using 3
rd
-party power supplies.
Guitar/Audio Connections
Using standard ¼” mono cables, connect your guitar, bass, or other instrument to the INPUT 1 jack
and your amp (or the next audio device in the signal chain) to the OUTPUT 1 jack. When running a
stereo rig, also use Input and Output 2.
Once the power and audio connections have been made, the Spectrum is ready to play.
