1. VOLUME: This control sends the signal volume from the preamp to the power
amplifier. Turning the knob clockwise increases volume.
2. BASS INPUT: Plug your bass in here. Input impedance is 1 meg ohm.
3. POWER INDICATOR: When your amp is on, this L.E.D. will glow. The Bass 400 x 2
uses an L.E.D. instead of a normal bulb because L.E.D.'s last up to 10 times longer.
4. POWER LEVEL INDICATORS: These L.E.D.'s show the amount of power being
demanded from the power amp, The bottom orange L.E.D. indicates 3 db below rated
power. The bottom red L.E.D shows 3 db past the rated power.
Sustained operation in the top red L.E.D. region can cause severe damage to speaker
systems due to the high level of distortion.
5. GRAPHIC EQUILIZER: This is an active equalizer system that provides 15 db of
boost and cut (total range is 30 db) per band. Each band of the E.Q. is independent. You
can vary the individual bands as much as you want without affecting the range of the
E.Q. controls.
By combining the graphic equalizer with the low contour switch, it is possible to achieve
30 db of gain boost at very low frequencies. Because the power amp is easily capable of
providing very low frequencies there is a potential threat to damaging speaker systems
through cone over-excursion.
