3. Pre-Amp A (Tube Emulation) control - This determines the amount of pre- amplification 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. -

10. Master Volume control - This is the overall volume control. For best sig- nal-to-noise ratio, keep the output of your bass at or near maximum and adjust the amp’s Master Volume to the desired level. 11. Power LED - Lights whenever the Model 2500 is powered on. -

Model 2500. Make sure the voltage rating is correctly set before powering up the amplifier! Fuse ratings are 10 amp for 115 vac and 6.2 amp for 230 vac. For information on how to change the voltage rating, see Appendix B on page 14. - Page 9 Guided Tour - 2500 Rear Panel 5. Effect Send jack - Use this 1/4” unbalanced jack to send low impedance (100 ohm) signal from the Model 2500 to a professional outboard effects processor such as a reverb, echo, chorus, flanger, or harmonizer device.* Output level is approximately 0 dB to +4 dB and is post-EQ and post-compression but unaffected by the setting of the Master Volume control.

“Active” input; if not, connect it to the “Passive” input). On the front panel of the Model 2500, set the Master volume control to “0” (fully counterclockwise) and set both Pre-Amp A (Tube Emulation) and B (Solid State) knobs to “5” (the twelve o’clock position). Set the Compression knob to its “Off” position (fully counterclockwise—you’ll hear a click) and set both Contour knobs to their center... -

“10” position since this setting will almost always result in undesirable distortion. 8. When you have settled on a Pre-Amp balance, the next step is to adjust the two Contour (bass and treble equalizer) controls to taste. For more information, see the “About Equalization”... -
Page 12: About Equalization
EQ controls allow you to alter a sound by boosting or attenuating specific frequency areas—they operate much like the bass and treble controls on your hi-fi amp, but with much greater precision. The Model 2500 provides you with two different means for equalizing your bass sound: •... -

EQ controls in the form of its tonal set- tings—this can be particularly effective in instruments that have active circuitry. Also, try various EQ settings with different Pre-Amp blends and with and without Compression. For more information, see the “About Compression”... -
Page 14: About Compression
About Compression The dynamic range of a sound is the difference between its loudest and soft- est points. For example, as you play your bass, you’ll probably find that some notes (for example, notes played on the upper frets of the lowest string) are considerably louder than others. -
