PAD - Attenuates the input signal by 30dB. It affects both the XLR and jack inputs.
Press this switch when the input signal is too high with the GAIN control backed off.
GAIN - Use this control with the PAD switch to adjust the channel input sensitivity to
match the connected source (-60 to +10dBu) to the console operating level (0dBu).
Press the PFL switch to check that the signal reads an average ‘0’ on the meters.
100Hz LO-CUT FILTER - Attenuates frequencies below 100Hz to reduce low
frequency source noise such as microphone proximity popping, stage noise and
transport rumble. It can also be used to clean up sounds which do not have much
bass content, such as vocals and cymbals.
EQUALISER - This provides separate, simultaneous control of 4 frequency bands.
Each band may boost or cut by up to +/- 15dB. The centre flat position is detented for
quick resetting.
The HF and LF bands have a shelving response which means that all frequencies
beyond the turning point frequency are affected, HF = 12kHz, LF = 60Hz. Use HF to
add sparkle or to reduce source hiss. Use LF to add punch to the bass instruments.
Used with the LO-CUT filter you can tailor the low frequency response exactly as you
require.
The two swept mid frequency bands have a peak/dip (bell shaped) response which
means that the maximum boost or cut occurs at the selected (centre) frequency. The
centre frequency can be swept over a wide range. MF1 = 500Hz to 15kHz, MF2 =
35Hz to 1kHz. Use the mids to add warmth or presence to the sound or to notch out
problem resonances which can result in feedback.
EQ IN - Press to switch the EQ into the signal path.
AUXILIARY SENDS - You can set up to 6 separately balanced mixes using the aux
send controls. Up to +6dB of additional boost is available.
Aux 1 - 4 and Aux 5 - 6 can be used as either MONITOR SENDS to the performers or
as EFFECTS SENDS to external signal processing equipment. The output can be
monitored using the aux send master AFL system. MONITOR SENDS are normally
set pre-fader (PRE) and EFFECTS SENDS normally post-fader (POST). When set to
POST, the amount of channel signal in the monitor mix is dependent on the channel
fader level. Pre-fade aux sends are post-EQ, post-ON as standard (can be
reconfigured pre-EQ or pre-ON by setting internal links).
PAN - Positions the channel signal within the stereo image, L (odd groups) and R
(even groups). The centre position (mono image) is detented for quick resetting.
ON - This turns the channel signal on or off.
PEAK - The red LED illuminates when the signal is within 5dB of clipping. Should this
occur turn back the GAIN control to reduce the signal level. This LED also half
illuminates when a PFL switch is pressed.
PFL - Press PFL (Pre Fade Listen) to listen to the pre-fade signal on headphones or
local monitor without affecting the main outputs. The signal level is shown on the L
and R bargraph meters.
L-R, 1-2, 3-4 ROUTING SWITCHES - These switches route the channel signal to L-R
master and groups 1-2, 3-4. Use the pan control to route to individual groups, i.e. left
to L, 1 or 3, or right to R, 2 or 4.
+48V PHANTOM POWER - This is switched individually for channels 1-4, global for
channels 5-10 on the rear panel. Phantom power may be switched off altogether with
global +48V switch located on the front panel near the headphone socket.
Channel fader - 100mm smooth action fader controls the overall channel level. All
post fade aux send levels are dependent on the level of the channel fader.
