F ront Panel Overview
A. INPUT JACK
Input connection for your guitar.
B. TRIM
Sets the input signal level for proper analog�to�digital conversion. Adjust TRIM so that most of the green LEDs stay on at normal playing levels and the red LED flashes occasionally while playing at peak intensity. This knob is not preset programmable nor motorized.
C. GAIN
Adjusts the distortion level and contributes to overall amplifier loudness. Use VOLUME {D} to compensate for any undesired volume level change resulting from a GAIN level change.
D. VOLUME
Adjusts the post�distortion signal level and contributes to overall amp loudness. Use in conjunction with GAIN {C} to normalize volume differences between presets. Several knobs affect the overall loudness of the amplifier:
Knob TRIM GAIN VOLUME MASTER Function Supply proper signal level to DSP Adjust distortion level Equalize level differences between presets Global volume and maximum level governing Preset Programmable NO YES YES NO MIDI Controllable NO YES YES YES Expression Pedal Controllable NO YES YES YES
E. TREBLE / MIDDLE / BASS
Adjusts tone in the high�, mid�, and low�frequency ranges respectively.
F. PRESENCE
Adjusts tone in the ultra-high frequency range after the distortion circuitry for a crisp tone sparkle.
G. REVERB
Adjusts the level of the active Reverb. Enter AMP edit mode to select Reverb types and edit Reverb parameters (see page 14).
H. MASTER VOLUME
Controls the overall loudness of the amplifier globally, independent of any preset. MASTER VOLUME is not preset programmable, although it is motorized so that it can be controlled remotely by expression pedal or MIDI. Remote operation of MASTER VOLUME is limited to a maximum value defined by where the MASTER VOLUME is set manually on the front panel. Set the MASTER VOLUME knob to the desired maximum level and motorized control will be confined to the range below that boundary.
