1. INPUT: The signal output from an
instrument (active or passive) may be
connected to this 1/4" Input by means
of a shielded instrument cable.
2. –15 dB PAD: Press this switch in to
reduce the input signal by 15 dB and
compensate for higher output sources.
This attenuation is suited for use with
basses that have active electronics or
high-output pickups. Use this Pad if
you notice that the peak LED [3] comes
on regularly. It will reduce the chance
of over-driving the preamplier stage,
and allow more usable range and ne
adjustment of the Gain control.
3. PEAK LED: This red warning LED
will come on if the input signal is too
high, the Gain control is set too high,
or there is too much boost from the
Bass, Midrange and Treble controls. If
it comes on regularly, even when these
controls are low, try engaging the –15
dB Pad [2].
4. GAIN: This varies the amount of signal
driving the preamplier. If a small
clockwise rotation from minimum
leads to overloading and the peak LED
illuminating, try engaging the –15 dB
Pad. This will give more usable range
with the Gain control.
5. BASS: Use this to adjust the low
frequency level of the amplier. This
provides up to 14 dB of boost, or –12
dB of cut, at 40 Hz. The low frequency
output is attest at the center position.
6. MIDRANGE: Use this to adjust the
midrange frequency level of the
amplier. This provides up to 5 dB of
boost, or –13 dB of cut, at 500 Hz. The
midrange frequency output is at at
the center position. Rotate the control
counter-clockwise for a “contoured”
sound (more distant, less midrange
output) or clockwise for a sound which
really cuts through.
