Linking lets you gang the preamp, processing and
routing of an odd/even mono channel pair for stereo
operation. All parameters including the preamp,
processing and routing are linked. Pan becomes a
width control when linked. Some parameters can be
removed from the link using the buttons:
Preamp – Gain/48V, Polarity
Dynamics (Compressor and Gate) - Side Chains
Main mix – Fader/Mute, Pan
Touch Apply to accept your changes.
Gate
The Noise Gate can be switched in to dynamically turn
off the audio when it drops below a certain level. For
example, to reduce resonant decay of a kick drum or
floor tom, or hiss of a noisy keyboard.
Use the In key to switch the Gate in or out. This is
similar to inserting an outboard rack mounted device
into the Insert socket on an analogue console channel.
Set Depth for how much signal reduction you want
when the gate closes. 20dB is a typical setting. Sound
check the instrument and reduce Threshold to shut off
as much of the tail of the signal as you want. The GR
indicator lights and red screen meter shows the
amount of reduction when the gate is closed.
Hold sets how long the gate remains open after
dropping below the threshold. Attack sets how fast the
gate opens when the signal rises above the threshold.
Release sets how fast it closes when dropping below
the threshold. Experiment with these controls to
achieve smooth operation without a pumping effect.
HPF
The High Pass Filter is used to reduce unwanted low
frequency sounds such as vocal popping, wind noise
and stage rumble.
Switch the HPF in using the In key. Use the panel
rotary or screen button and rotary to sweep the cut-off
frequency until you have reduced the unwanted
sound. The filter has a 12dB slope and can be swept
from 20Hz to 2kHz. The violet screen curve shows the
resulting frequency response.
PEQ (parametric equaliser)
The Parametric Equaliser allows tonal adjustment of
the channel sound. It splits the 20Hz to 20kHz audio
frequency range into 4 bands:
LF (low frequency)
LM (low mid frequency)
HM (high mid frequency)
HF (high frequency)
Each provides 3 parameters that can be adjusted:
Gain – Boost or cut frequencies by up to 15dB. Centre
0dB is flat response (no affect).
Gate active
GR = Gain Reduction
