INPUT GAIN - SIGNAL LEVEL INDICATION
Set the INPUT GAIN control of channel 2 in the same way as for CHANNEL 1.
This control also has a PULL switch built into it to turn on the digital effects for this channel
( PULL REV ).
GRAPHIC EQUALISATION
The five bands of graphic equalisation offered have their centre frequencies chosen specifically to
suit acoustic instruments and may be used to adjust the overall sound of the amplifier.
Avoid extreme settings on any slider as these are unlikely to give useful results. Also avoid
boosting the 100Hz slider too much as this will tend to increase the chances of low frequency
feedback.
POWER LED
This LED indicates when the amplifier is connected to the mains supply and switched on.
DIGITAL EFFECTS
The 16 bit Digital effects board built into the TRACE ACOUSTIC amplifiers uses a 16 way rotary
PROGRAM switch for selection of the 12 reverb and the 4 delay settings, and a LEVEL control to
adjust the depth or amount of reverb added to the signal.
Reverb is assignable to each channel by means of the PULL REVERB switch on the INPUT GAIN
controls of both channels.
The digital effects selectable with the 16 way rotary switch are as follows:-
( these are different to those available on the previous models )

A lower noise unit with a better selection of effects has been used in these second generation
TRACE ACOUSTIC AMPLIFIERS.
NOTCH FILTER ( ANTI FEEDBACK )
All models in the TRACE ACOUSTIC series include a NOTCH FILTER that can be switched IN and
OUT. This is included as an anti-feedback device to allow amplification of an acoustic instrument
( particularly acoustic guitar ) without trouble from feedback caused by the resonance of the body
of the instrument.
