Normal and High inputs are provided for connection of bass guitars. High output basses, either Active or Passive should be
connected via the High socket. Low output basses should be connected using the normal input. High output basses may also
be placed in the Normal input if pre-amp overloading is desired.
This control is used to set the level of gain present in the pre-amp. The higher the level of gain, the more the signal will clip
producing distortion. The Gain control should be used in conjunction with the Volume control to produce the desired signal
characteristics.
Engages and disengages the on-board compressor, this compresses the input-signal giving a punchier sound. In association with
the compressor are two LEDs, one indicating that the compressor is engaged and one indicating the compressor is active. The
amount of compression is controlled by the Gain control. The higher the setting the more compression. With most guitars
compression will begin at about 5-6 on the control. It is possible to have the compressor engaged but it only be active during
certain periods of playing - typically the most dynamic sections.
