The “out” position defeats the Chorus. NOTE: The Chorus effect must be activated to be controlled via remote footswitch. CHANNEL SELECT SWITCH (5) Allows selection of the Lead or Normal channel. The “in” position of the switch selects the Lead channel and the “out” position selects Normal. NOTE: Channel selection may also be accomplished by the remote footswitch. If the remote selection is desired the channel switch must be in the “in” (Lead) position. LOW, MID, & HIGH EQ (6) Passive tone controls that regulate the low, mid and high frequencies, respectively. S UPERSAT®/PULL GAIN (7) A transistor simulation of tube distortion (soft clipping). To activate the SuperSat effect, Lead channel must be activated. Pull Gain switch boosts overall system gain. Pull to activate. POST GAIN (8) Controls the overall volume level of the Lead channel. The final level adjustment should be made after the desired sound has been achieved. BOTTOM (9) An active tone control (shelving type ±15 dB) that varies the low frequency boost or cut. NOTE: This control is not functional on the Normal channel. BODY (10) An active tone control (peak/notch, ±15 dB) that varies the mid frequency boost or cut. NOTE: This control is not functional on the Normal channel. EDGE (11) An active tone control (shelving type, ±15 dB) that varies the high frequency boost or cut. NOTE: This control is not functional on the Normal channel. REVERB (12) Controls the overall reverb level. RATE CONTROL (13) Controls the sweep rate (frequency) of the chorus effect. DEPTH CONTROL (14) Controls the depth (intensity) of the chorus effect. POWER LED (15) Illuminates when AC power is being supplied to the amp. 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. 17 LINE CORD (120V PRODUCTS ONLY) (17) For your safety, we have incorporated a 3-wire line (mains) cablc with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with the proper grounded receptacles. PREAMP OUT MIX 2 (18) The Preamp Output can be used to route the amplified signal to a mixing console, tape recorder, etc. connect the Preamp Output, using a shielded cable, to an input of the tape recorder, mixer, outboard power amplifier, etc. This patch does not affect the operation of the amplifier. NOTE: When only the preamp out mix 2 jack is used, the mixed chorus effect is present at this point. (Combination of dry and chorused signals) When both preamp out jacks are engaged, only the chorused signal appears at this point. STEREO HEADPHONE JACK (19) Provided for use with any stereo headset. One channel of the headphones will deliver signals processed by the chorus circuit. The other side will deliver only “dry” (unprocessed) signals. Use of a monaural headset is not recommended. PREAMP OUT DRY 1 (20) The preamp output can be used to route the amplified signal to a mixing console, tape recorder, etc. Connect the preamp output, using a shielded cable, to an input of the tape recorder, mixer, outboard power amplifier, etc. This patch does not affect the operation of the amplifier. NOTE: The dry (unchorused) signal is always present at this point even when both preamp out jacks are en- gaged. This jack should be used for normal preamp out patching when the chorus effect is not desired. REMOTE SWITCH (21) Provided for connection of the optional remote footswitch (#5996). The footswitch is used to select the Lead or Normal channels and defeat reverb and the chorus effect.
