Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 230V power, or vice versa.
Mono Input Channel
Each mono channel comes with a XLR Mic input (
1
) and a balanced Line input on 1/4” jack (
2
). Phantom
powering is switch able from the panel (
34
). The trim circuit has a wide range from +10dB to +60dB,
obviating the need for mic / line switching. The crucial operating input level +4 dBu and –10 dBV are clearly
and accurately marked (
4
).
1. Input Level Setting
Mic Channel input level is determined by the TRIM control (
4
). In addition to Master Mix metering, a channel
PEAK LED (
11
) illuminates, when a channel is going into overload. These LEDs take their cue from post-
EQ. This level sampling is particularly useful when using extreme EQ settings.
2. Equalizer
All mono input channels are fitted with 3-band EQ, plus a switch able Low Cut filter for eliminating unwanted
subsonics. The upper (
5
) and lower (
7
) shelving controls have their frequencies fixed at 12 Khz and 80 Hz
respectively. The Mid range control (
6
) has a peaking response, with Q fixed at 2 octaves, frequency at 2.5
Khz. All 3 bands have up to 15 dB of cut and boost, with a centre detent for “OFF”. The Low Cut filter (
3
),
slope at 18 dB/oct., -3 dB at 75 Hz, is ideally suited for reducing floor rumble, breathing noises and popping,
woolly bottom end, etc.
3. Aux Sends
Both Aux Sends
(8
&
9)
are mono and post-EQ. Aux Send 1 (
8
) is set pre-fader, while Aux Send 2 (
9
) is
post-fader.
Aux 2 can be made pre-fader on mono channels Aux 2, see “Modification” for more details.
4. Fading and Panning
GAIN to the Master Mix bus is ultimately determined by the Channel Volume control (
13
).
Channel Pan (
10
) positions the output of the channel in the stereo field. Its constant-power design ensures
there are no level discrepancies whether a signal is hard-panned, centre-stage or somewhere in between.
Such pinpoint accuracy will be a revelation, if you have been working on consoles with lower quality circuits.
5. PFL
Depress switch (
12
). The MONO channel signal can be level to the switch (
17
), its origin of the
HEADPHONE / CONTROL ROOM.
