This control regulates the first amplification stage and controls the gain
of the first stage in the overall system. The compressor automatically
tracks the input level and follows the gain. This is a fixed-threshold type
compressor. You control the compressor threshold by setting the gain
higher or lower; depending on how much compression effect you want.
The compressor is also provided with a bypass switch to defeat the
compressor operation if desired. For most instruments, you should set
the control between 9:00 and 3:00 to match your instrument and playing
style to the amplifier.
-12dB PAD Main Channel
Some of the dual battery powered bass guitars have unusually high
output levels. If you own one of these basses, it may be necessary to
engage the -12dB pad in order to properly match correct signal levels
with this unit. The pad is engaged by pushing in the pad switch. This will
reduce the input signal level by approximately –12dB.
ACTIVE LIGHT and COMPRESSOR ON/OFF SWITCH Main channel
The compressor on/off switch engages and disengages the compressor.
Pushing in the compressor switch activates the compressor. The light
indicates the best spot to operate the amplifier. When the compressor is
engaged, the light indicates compressor operation. When the
compressor is bypassed, it indicates the sweet spot for operating the
amplifier.
ENHANCE CONTROL Main Channel
This is a great sounding feature, seldom found on amplifiers in this price
range. The enhance control is a complex tone pre-shaping curve that is
set up to optimize your bass sound. It is designed to boost the low
frequencies and upper midrange, while at the same time reducing the
lower midrange frequencies. The enhance control is a quick and easy
way to a quality bass tone. To try it out, set all the other tone controls to
flat. Then rotate the enhance control between 9:00 and 11:00 for the full
effect. This range is typically the best area for operation. The enhance
