ATTACK:
Activates a fast attack compressor circuit. This is auto triggered by the output section, and prevent distortion
at high output levels.
When the amplifier is set for a high gain and high output volume; noise, hum and acoustic feedback
may become apparent. When selected (Pressed in) the noise reduction circuit is activated when playing ceases, greatly
reducing the unwanted noise. Note this is designed to be used at high gain and volme levels, use at low levels can
cause unwanted noise and result in premature signal cut off.
Illuminates when amplifier is switched on.
Indicates the strength of signal present in the pre-amplifier. If an ORANGE LED is
displayed the level of signal should be increased by means of the Pre-amp gains, using the appropriate gain controls. If
a GREEN LED is displayed the signal is at its optimum level. If a RED LED is displayed then the level present is too
high and should be adjusted accordingly.
Adjusts the level of gain for the FET (solid state) section of the pre amp. This control is only active if the
FET pre amp selector is assigned or if both pre amp modes are selected simultaneously
Controls the HIGH level frequency content of the amplifier.
Allows for the connection of an instrument using either XLR connectors of
Jacks
Pad switch for selecting between ACTIVE and PASSIVE input sources.
Switches the on board compressor on.
Controls the output level of the compressor when the compressor is switched on.
Controls the compression range and the length of sustain. Turning the control clockwise increases the level
of sustain.
Controls the envelope of the signal. Turning the control clockwise emphasizes the attack.
