1.0 dB INPUT: The signal output from a passive instrument may be connected to this 1/4" input by means of a shielded instrument cable.

2.-15 dB INPUT: The signal output from an active instrument may be connected to this 1/4” input by means of a shielded instrument cable.

3.GAIN: This control adjusts the basic level of signal in the preamp.

4.ULTRA HI: This switch, when engaged, enhances the amount of high frequency output by 9 dB at 8 kHz.

5.ULTRA LO: This switch, when engaged, enhances the amount of low-end output by 2 dB at 40 Hz and -10 dB cut at 500 Hz.

6.BASS: Use this to adjust the low frequency level of the amplifier. This provides up to 12 dB of boost, or 12 dB of cut at 40 Hz. The low frequency output is flat at the center position.

7.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 the selected frequency [8]. 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.

8.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.

9.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.

10.MASTER: Use this to control the overall output level. It affects the speaker outputs and the preamp output. Use it wisely, and turn it down when making connections or trying something new.

11.STANDBY/POWER/FAULT INDICATOR LED: This is a multi-function LED. In Standby mode, it glows red. In the On mode (when the high voltage comes on) it glows green. If it does not turn green in the On mode, there is no high voltage present and the unit needs to be serviced. If the amp detects a fault in the power tube circuit, the high voltage is turned off and the LED flashes between red and green. This usually indicates a bad power tube. The amp will remain in this condition until the unit is turned off.
