5. LCD: This blue LED backlit display shows the names of presets and TAgS, as well as listing
parameters as well as MIDI activity (indicated by a note) and audio output levels (L / R meters) are
displayed on the LCD.
6. Main Function Buttons: These eight buttons provide control the main functions of MuseBox
and let you control and program the sounds or effects in the MuseBox. The buttons are described in
detail in the next section.
7. Front Panel Input Gain Controls: This control sets the input gain of the front panel
microphone/instrument input, with the top one controlling input "A," and the bottom one controlling
input "B." These gain controls do not affect the line level inputs on the back; they only control the
front panel input gain settings.
Note: Before connecting either an instrument or microphone to the front panel inputs, turn the
GAIN control all the way counter-clockwise to its minimum setting to prevent overload or feedback
audio signals that could damage speakers.
8. Front Panel Input Led Level Indicators: These three LEDs show you the level of the inputs
(both front and rear). The green LED indicates signal presence (-40dB and above); the amber LED
shows levels above -7dB; and the red LED indicates the onset of clipping (-1dB). For best fidelity,
your input should trigger the green and yellow LEDs regularly and very rarely, if ever, trigger the
red LED. If the red LED stays lit on a regular basis, your input level is too high and you should turn
the gain control counter-clockwise until the red light is no longer lit.
9. Phantom Power Switch and Indicator LED: When this switch is depressed, the 48VDC
Phantom Power is applied to the Microphone jack to power condenser-type microphones. When the
Phantom Power is active, the red LED above the switch will illuminate.
NOTE: You should reduce the output level of MuseBox or reduce the input gain of any amplifiers
attached to the MuseBox outputs when turning on and off the phantom power, as it can cause a
slight audio pop or thump to occur in the audio outputs.
10. Front Panel Microphone/Guitar/Bass Inputs (A and B): These two high-grade
combination microphone/instrument input jacks feature a high impedance guitar preamp on the
1/4" jack section in the middle of the jack, and a balanced, low-impedance input (with optional
phantom power ... see #9) for dynamic or condenser microphones. The top input is Input A; the
bottom is input B. When selecting PLAY presets, the default input for your guitar is Input A on top,
and the default input for your microphone is B on bottom.
