1. Passive Input jack- If your bass guitar has passive circuitry, connect it to the Model
5000/7000 here. This standard 1/4� unbalanced jack provides a high impedance (100 k Ohms)
input sensitivity of 20 millivolts.
2. Active Input jack- If your bass guitar has active circuitry,* connect it to the Model 5000/7000
here. This standard 1/4� unbalanced jack provides a high impedance (100 k Ohms) input sensi-
tivity of 60 millivolts.
3. Pre-Amp A (Tube) control - This determines the amount of preamplification being provided
by special circuitry which simulates the sound of a classic tube amplifier (this circuitry actually
includes a real tube!). Note that when both Pre-Amp knobs are used at equal settings, the
amplifier will be twice as loud as when only one is used. Avoid setting both Pre-Amp knobs
on maximum (O10�), since the result will almost always be undesirable distortion.
4. Pre-Amp B (Solid State) control - This determines the amount of preamplification being
provided by special circuitry which simulates the sound of a solid state amplifier. Note that when
both Pre-Amp knobs are used at equal settings, the amplifier will be twice as loud as when only
one is used. Avoid setting both Pre-Amp knobs on maximum (O10�), since the result will almost
always be undesirable distortion.
5. Compression LED- Provides a visual indicator of the status of the compression circuitry.
When lit steadily green (for example, when the Compression knob [see #6 below] is set to OOff�),
no compression is being applied. When unlit, compression is being applied to the incoming sig-
nal at a ratio of approximately 2:1. When flashing red, the compression ratio is approaching
infinity (limiting is being applied to peak signals). When lit steadily red, the entire signal is being
limited. This LED Ofollows� the incoming signal, changing continuously as different amounts of
compression and/or limiting are being applied. For more information, see the OAbout
Compression� section on page 11 of this manual.
6. Compression control - This determines the amount of compression (peak signal reduction)
by simultaneously adjusting both threshold and compression ratio (which ranges from 2:1 to
infinity [limiting]). At the fully counterclockwise OOff� position, the circuitry is bypassed and no
compression is applied (the knob clicks when set to the OOff� position). As the knob is raised
clockwise (at settings from O1� to O �) increasing amounts of compression are applied. For more
information, see the OAbout Compression� section on page 11 of this manual.
* Bass guitars that have active circuitry normally require a battery for the circuitry to be func-
tional.
