whenever the amplifier is turned on, providing constant, “real-time” tuning. The bottom row of LEDs indicate which note (string) is being tuned. The top row of LEDs provides direc- tional queues to facilitate quick and precise tuning of your instrument. The indicated note (string) is properly tuned when only the center LED is illuminated.

16:EXTENSION SPEAKER: Use this jack to connect the amplifier to an external speak- er. The internal speaker is disconnected when this jack is used. The impedance of the external speaker must be 4 ohms or greater.

WARNING: Do not attempt to use headphones in the Speaker jack! Permanent hearing damage could result!

17:FOOTSWITCH: Use this jack to connect the 1/4” stereo plug on the cable of a two-but- ton footswitch (such as the Crate CFP2). This allows you to remotely switch between the Clean and Solo channels and turn the DSP function on and off.

18:POWER CORD: The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements stated on the bottom panel. Do not attempt to defeat the safety ground connection.
