 Gain
Adjusts the sensitivity of the electronically balanced XLR input, from +15dBu to +60dB.
48V Phantom Power
Applies 48V phantom power to the input XLR.
-20dB Pad
Reduces the input sensitivity of the XLR by 20dB, to allow line level signals to be connected via the XLR.
Line Switch
Selects a separate high-impedance input via 1/4" jack on
the rear panel. This signal replaces the XLR signal and is attenuated by 20dB.
Peak
Illuminates when the internal signal reaches 3dB below clipping level, monitored at two points, pre and post the
EQ.
Phase
Reverses the phase of the selected input.
Hi-Pass Filter
The switchable 12dB/octave variable high-pass filter can be varied from 30-400Hz for effective removal of unwanted low frequency content.
EQ Section
The EQ section is four band, with shelving sweep high and
low frequency
sections, and swept high-mid and low-mid bands. The frequency
ranges are 1.2kHz-20kHz (HF), 750Hz-13kHz (High Mid), 75Hz-1.3kHz
(Low Mid) and 30Hz-550Hz (LF) with 15dB cut/boost available at any
frequency. The Q is fixed on the two mid bands at 1.5.
Balanced Insert Point
Separate jacks provide a pre-EQ balanced send and return,
at a nominal level of 0dBu.
Direct Output
A Direct Output on balanced 1/4" jack is source-selected
by the DIR PST switch. The function of the switch when up and
down can be selected by 2 internal PCB jumpers:
Aux Sends
There are 10 aux sends, which can be used either as FX sends
in FOH use, or monitor mixes for monitoring.
Aux 9&10 can be switched
to work as a stereo pair, with separate level and pan for use as an
in-ear send,
using the adjacent STE switch.
Each send has a maximum gain
of +6dB. The auxes can be switched pre- or post-fader by the
adjacent PRE switches, which are in pairs for aux 1-4 and aux 9,10 and
as one group for
aux 9-12.
The pre-fade signal for all auxes is normally post-EQ
but can be switched to pre-EQ using the AUX PREQ switch (both feeds
follow the channel mute).
Subgroup Routing
In addition to the 10 aux sends, 8 busses are provided for
audio subgrouping. Routing is via 4 paired buttons, with the channel
pan pot
controlling the signal split between odd and even groups.
Mix Bus Routing and Pan Controls
The signal is sent to the stereo mix bus and the mono (C)
bus using the MIX and C switches.
The PAN control, which gives 3dB centre drop, operates on
the STE bus and group bus signals. The C bus is always fed directly with
the post-
fader signal at unity gain, unless LCR panning is engaged.
LCR Panning
The LCR switch changes the mode of the Pan pot from normal
left-right panning with a 3dB centre drop, to 3-way LCR panning, requiring
both the C bus and LR stereo mix bus to be routed, and the pan pot
panning from left to C, C to right. When the pot is physically centred,
there is no output from the left and right mix bus outputs.
SOLO
 The SOLO button provides a PFL feed to the engineer’s
headphones or monitors, or triggers a destructive solo in place, depending
on the mode selection at the master section.
The SOLO button can also
be activated remotely from a VCA solo when assigned to a VCA group, giving
stereo AFL. Intercancel or additive soloing is possible, with or without
input priority, and solos can be cleared with a single button press at the master
section.
The SOLO button also features automatic momentary operation,
by pressing and holding for more than 0.5 seconds.
MUTE
The MUTE switch mutes the signal to all busses, including pre-fade aux sends.
The mute can also be activated by the mute group system, an SIP mute signal or a VCA mute signal. It is also possible to activate
the mute by sending a MIDI note message into the console’s
MIDI
Input. The same MIDI messages are transmitted when the mute switch is manually pressed.
A preview mode allows editing and checking of mute groups without disturbing the audio passing through the desk, and mutes can be set ‘Safe’.
VCA Assignment
Each channel can be assigned to any combination of 8 VCA
subgroups, using the SOLO button on each channel, in conjunction with the VCA master SOLO switches in VCA Assign mode.
Once assigned to a VCA group, the channel’s fader level,
mute and solo button come under the control of the VCA master controls,
but can still be operated locally. Assignments are displayed
on the 8 LEDs next to each channel fader.
LED Input Metering
Every channel is fitted with a 12-segment LED bargraph meter, positioned next to each fader for maximum visibility and giving immediate graphic indication of incoming signals
at the output of the EQ.
