MID EQ (6) A passive tone control that adjusts mid frequencies. SHIFT (7) Shifts and selects the frequencies at which the Mid control operates. HIGH EQ (8) An active tone control (peak/notch type, +/- 15 dB) that varies the high frequency range. PRESENCE (ACTIVE) (9) An active tone control (+I5 dB) that varies the extreme high frequency range. 0 to +15 boost (increase). SENSITIVITY (10) Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired sound has been achieved. EFFECTS PATCH 1 (11) Provided for connecting external effects devices into the signal path. To patch an effects device, connect the send jack to the input of the device. Connect the output of the device to the return jack. High-quality shielded cables should be used for these connections. EFFECTS PATCH 2 (12) Provided for connecting external effects devices into the signal path. To patch an effects device, connect the send jack to the input of the device. Connect the output of the device to the return jack. High-quality shielded cables should be used for these connections. REVERB (13) Reverberation is an echo effect. Rotate clockwise to increase the effect. Remote footswitch can control On/Off. PILOT LIGHT LED (14) Illuminates when AC power is being supplied to the amp. GROUND SWITCH (15) Three position rocker-type switch which, in most applications, should be operated in its center or zero position. There may be some situations when audible hum and/or noise will come from the loudspeaker. If this situation arises, position the ground switch to either positive or negative (+ or -) or until the noise is minimized. NOTE: Should the noise problem continue, consult your Authorized Peavey Dealer, the Peavey Factory, or a qualified service technician. THE GROUND SWITCH IS NOT FUNCTIONAL ON 220/240 VOLT MODELS. POWER SWITCH (16) Depress the switch to the “On” position. The red pilot light (LED) will illuminate indicating power is being supplied to the unit.
