1. PoWEr
To power the unit, insert 4 AA batteries (included) or connect a
Source Audio SA150 9 Volt DC power supply to the 9V DC jack
Note: Power supply must be REGULATED , minimum 200mA, and use a
negative tip plug. Use of a non-Source Audio power supply may cause
damage and void the warranty.
2. GUItAr/AUDIo ConnECtIons
Next, plug your guitar (or other instrument) into the jack labeled
GUITAR IN (B) via a standard ¼-inch cable. Connect your amp (or
other audio device) to the GUITAR OUT (C) jack, again with a standard
¼-inch cable. Both input and output are mono signals.
Note: The unit will not power up until a MONO ¼-inch plug is inserted into
the guitar input. This is to conserve power when the unit is running on bat-
teries. Don't forget to unplug the cable from the input when the unit is not in
use—otherwise the batteries will continue to drain.
3. sEnsor In (optional)
To use your Multiwave Distortion with a Hot Hand sensor: Connect
the sensor to the SENSOR IN (D) jack and follow any instructions
supplied with the sensor. The sensor input works with both wired and
wireless sensors.
