11. DSP MODE: Use this control to select one of the eight built-in digital effects. A listing of the effects is
printed below the control knob. A brief description of these effects is shown on page 3 of this manual.
12: DSP LEVEL: Use this control to adjust the output level of the digital effect: in its fully counter-
clockwise position the signal will be “dry” (without any effect). As you rotate the control clockwise the
amount of effect increases.
13. CD INPUT LEVEL: Use this control to adjust the input level of the signal from the CD Input jacks
(#14).
14. CD INPUT JACKS: Use these jacks to connect the output of a CD player, tape deck or drum
machine to the amplifier. The jacks are internally summed to create a mono signal.
15. HEADPHONES: Use these jacks to connect one or two pairs of stereo headphones to the ampli-
fier. Each Headphones jack monitors the signal from both Channel A and Channel B. The internal
speaker is disconnected when the Headphone jacks are used.
16. ELECTRONIC TUNER: The electronic tuner is active whenever the amplifier is turned on, pro-
viding constant, “real-time” tuning. The bottom row of LEDs indicate which note (string) is being
tuned. The top row of LEDs provides directional queues to facilitate quick and precise tuning of your
instrument. The indicated note (string) is properly tuned when only the center LED is illuminated.
17. LED: This LED illuminates when the amplifier is on.
18: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of
the switch depressed).
