[. . . ] Depressing the switch to its "in" position reduces the level of the input signal by 10 dB. INPUT JACK (2) This input will accept signals from all types of bass pickups. LOW CUT SWITCH -- CLEAN CHANNEL (8) Passive low frequency roll-off filter that is activated when the button is in the "in" position. [. . . ] the impedance switch selects the total impedance plugged into the amplifier. IMPEDANCE SELECTOR SWITCH (32) Used to select the impedance of the total load plugged into the speaker jacks of the amplifier. Front panel Channel Select and Channel Combine switches must be in the "out" position for footswitch to function properly. xLR JACK (34) A transformer balanced 600 ohm XLR jack is provided for direct patching of the amplifier to recording or sound reinforcement consoles. GROUND LIFT SWITCH (35) Provided to lift the XLR jack ground when hum loops are encountered when patching the amplifier to mixing consoles. Next, connect the output of the device to the Power Amp Input (highquality, shielded cables must be used for these connections). The Preamp Output can also be used to route the line level signal to a mixing console, tape recorder, etc. connect the Preamp Output , using a shielded cable , to an input of the tape recorder , mixer , etc. Note: The Preamp Output level is approximately 1 volt RMS and is of relatively low impedance (600 ohms). Any effects device used in this effects loop must be capable of receiving 1 volt input and providing 1 volt output in order to properly drive the power amp.

Clean Channel Settings: Pre Gain: 5 Low: 5 Mid: 5 Mid Shift: 600 Hz High: 5 Low Cut: Out Low Boost: Out High Boost: out Crunch Channel Settings: Pre Gain: 5 Low: 5 Mid: 5 High: 5 Low Boost: Out High Boost: Out Due to our efforts for constant improvements, features and specifications listed herein are subject to change without notice. In order to thoroughly understand the unit's functions, please study this diagram carefully. Note: Channel Combine Switch may be set in the "in" position to mix the distortion sound with the clean sound. Tone settings given are general and will vary according to the type of guitar, gauge type of the strings, the type of pickup, and even the type of pick. Personal preference, playing style, and type of music greatly contribute to desired tonality. La position « out » sélectionne le canal « clean ».
