GAIN TRIM
This control is used to adjust the input
gain and affects both the XLR and the
RCA inputs. The input gain can be
adjusted by +/- 15dB. This allows a wide
rage of program sources to be set up with
optimum gain structure. With the gain trim
in the centre position, the boost/cut is set
to 0dB. See the block diagram on page 10
for details of the gain structure.
2
LEVEL
Controls the level of the input signal.

INPUT STATUS LEDS
Each input has an LED status indicator.
The LED is green when there is signal
present and red if the signal is
approaching clip. If the LED begins to light
red this would indicate the internal signal
level is 6dB before clip. Note that the front
panel level control is post status LED and
as such, the status LED is NOT affected
by the level control. If an input channel is
clipping use the gain control to adjust
the correct amount of input level.

CHANNEL TONE CONTROLS
Each input has a 2 band EQ.
Bass – +/-12dB 100Hz shelving
Treble – +/-12dB 10kHz shelving

signal. Note: The Mic/Line switches only
affect the XLR input.
