Output; Main Bargraph Meter; Direct Input - Focusrite MixMaster Mode D'emploi

- selects the higher frequency range (10 times the panel marking). With the X10 switch
x10
pressed in, parametric control is available from 1kHz to 10kHz. With the X10 switch in the
'out' position, parametric control is available from 100Hz to 1kHz.
- The Q control defines the width of the band of frequencies to be cut or boosted. Q is
Q
variable from 0.4 to 1.5 allowing broad or very fine frequency control. A low Q value affects a
relatively broad range of frequencies, a high Q value (knob turned clockwise) affects a relatively
narrow band of frequencies.
- the HF control gives 10dB boost or cut at a choice of 10, 14 or
HF / FREQUENCY
20kHz as selected by the FREQUENCY switch. For more gentle control of the brightness of
the mix the TILT setting selects a 2dB/octave slope.
O/L - gives warning of excessive signal levels at the output of the Equaliser.
- switches the Equaliser into the signal path when pressed. The switch illuminates to show
IN
that the Equaliser is active. Toggling this switch allows A/B comparison of the EQ'd/non-
EQ'd signal.

OUTPUT

- gives 3dB L/R trim to allow subtle correction of stereo imbalance (this
BALANCE
control is essential to optimise the effect of the Width control). BALANCE is only active
when the IMAGE IN switch is pressed.
- allows the apparent width of the stereo image to be increased to make the sound
WIDTH
seem more spacious, or to be reduced to give a tighter image. WIDTH is only active when the
IMAGE IN switch is pressed. Signals may be isolated from this section by being routed into the
MixMaster after the width control circuit, using the Direct Input - see "Direct Input" section
below. The width control works by analysing the difference between the right and left signals
and then amplifying the difference (width enhanced) or reducing this difference (width
reduced).
- activates the BALANCE and WIDTH controls when pressed. The switch
IMAGE IN
illuminates to show that the IMAGE controls (Balance and Width) are active.
OUTPUT TRIM - gives ±6dB of trim to optimise the output level to various recorders.
Adjust so that peaks in the signal are reaching '0' on the output meters with only occasional
limiting shown by blinking of the top Limiter Meter LEDs.
- switches the Expander, Compressor, EQ and Image sections out of
EFFECT BYPASS
circuit when pressed. This switch does not affect the operation of the Limiter (see below).
- activates the multiband limiter, which has a fixed threshold matched to the
LIMITER IN
input of the optional Digital Output. The Limiter is designed to operate just before the
overload threshold on the meters. The switch illuminates to show that the Limiter is active.
MAIN BARGRAPH METERS
- when pressed, switches the bargraph meters and the phase meter to read the
I/P switch
input of the unit. With the switch in the 'out' position, the meters monitor the output signal,
after the limiter but before the optional Digital Output.
- a 180º meter monitors phase coherence - important to avoid unexpected
PHASE meter
nulling if the signal is to be reproduced in mono.
OUTPUT LEVEL METERS - 16 segment LED bargraphs monitor the output signal,
or the input signal if the I/P switch is pressed. The far right LED (O/L) acts as an overload
indicator to warn of excessive levels which might result in severe distortion, particularly when
feeding external digital equipment or the optional Digital Output.

DIRECT INPUT

Two rear panel jacks are provided to allow a separate external signal to be mixed into the final
output, before the Limiter but after the Image section to add, for instance, a vocal or kick drum
in the centre with different processing. A mono source may be plugged into the
RIGHT/MONO jack to be automatically fed to both sides if required.
