Guided Tour - VX2510 & VX2515 Front Panel
1. Passive Input jack - If your bass guitar has passive circuitry, connect it
to the Model 2500 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 2500 here. This standard, 1/4” unbalanced jack provides a high
impedance (100 k Ohms) input sensitivity of 60 millivolts.
3. Pre-Amp A (Tube Emulation) control - This determines the amount of
preamplification being provided by special circuitry which delivers the sound
of a classic tube 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 (“10”), since the result will
almost always be undesirable distortion.
4. Pre-Amp B (Solid State) control - This determines the amount of pream-
plification being provided by special circuitry which delivers 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 (“10”), since the result will almost
always be undesirable distortion.
* Bass guitars that have active circuitry normally require a battery for the cir-
cuitry to be functional.
