MIDRANGE: Use this to adjust the midrange frequency level of the amplifier. This provides up to 10 dB of boost, or 20 dB of cut at 800 Hz. The midrange frequency output is flat at the center position. Rotate the control counter clockwise for a “contoured” sound (more distant, less midrange output) or clockwise for a sound which really cuts through.
FREQUENCY: This control allows you to select the center frequency for the midrange control, giving you a choice of five “voices” for the midrange. The numbers correspond to the following center frequencies: 1=220 Hz, 2=450 Hz, 3=800 Hz, 4=1.6 kHz, 5=3 kHz.
TREBLE: Use this to adjust the high frequency level of the amplifier. This provides up to 15 dB of boost, or 20 dB of cut at 4 kHz. The high frequency output is flat at the center position.
FX MIX: This control varies the mix between the direct (dry) signal and the effects (wet) when the effects loop is used. Full counterclockwise results in all direct signal (no effect) and full clockwise adds all effect with no direct signal. The fully clockwise position is equivalent to a series effects loop and should be used with such devices as limiters and equalizers.

MASTER: Use this to control the overall output level. It affects the speaker outputs and headphones output. Use it wisely, and turn it down when making connections, putting on headphones, or trying something new.
PHONES: Use this 1/4” TRS stereo output to connect your headphones. The output here is the line-level signal reaching the amplifier. The signal to the power amp is killed when headphones are connected. You do not need to disconnect the speaker cables from the speaker cabinet (but you could, if so desired). Before putting on headphones, make sure the master control is turned down. This will reduce the chance of hearing damage due to loud volumes.
POWER LED: This LED illuminates when the power is on.
POWER SWITCH: Use this switch to turn the overall system power on or off. Press the top of the switch to turn on the power. Press the bottom of this switch to put the amp into standby mode. It will not function, but the circuits are still live. To remove AC power, either turn off the AC mains supply, or unplug the power cord from the speaker and the AC mains supply.
