HEADPHONES / LOCAL MONITOR and 2-TRACK
The Console Monitor System
The engineer is able to listen to any channel, mix or
matrix signal using stereo headphones and an
amplifier/speaker system connected to the local
monitor output. In addition the C output provides an
engineers wedge monitor feed when the console is
configured for on-stage monitor operation. All have
independent level control. The headphones are
plugged into the right of the meterpod.
The source is selected as either the 2-track input,
main LR mix, main C mix, or LR combined with C
for listening to a 3 output LCR system using the
stereo monitor. Pressing any console PFL or AFL
switch overrides this selection with a priority well
suited to live sound applications. The selected
source can be listened to in mono or stereo. All
monitor outputs automatically dim by 20dB when
the TALK switch is pressed. The main C LED and
VU meters automatically switch to monitor any
selected PFL or AFL source.
2TRK SOURCE Press this switch to listen to the
2-track input in the headphones, local, and
engineers wedge monitors. The signal is fed in
mono to the engineers wedge. This lets you check
the output of a stereo recorder. This selection
overrides any selected LR and C monitor source
until released. It is itself overridden by P/AFL. The
2TRK source is not sent to the meters.
LR SOURCE Press this switch to listen to the
main post-fade LR output in stereo. It is overridden
by the 2TRK and P/AFL selections.
C SOURCE Press this switch to listen to the main
C (centre) output in mono. As with LR it is
overridden by the 2TRK and P/AFL selections.
LCR Press LR and C together to monitor a 3
output LCR system in stereo. This mixes the C
signal equally into L and R.
MONO Press this switch to listen to the selected
monitor source in mono. This only affects the
monitor outputs. It is useful to check for mono
signal compatibility. If the signal drops in level or
loses quality when monoed then there may be a
problem with phasing between left and right.
LOCAL MONITOR LEVEL Adjusts the stereo
local monitor output level.
PHONES LEVEL Adjusts the level of the monitor
signal in the stereo headphones.
WARNING
: To prevent damage to
your hearing start with the headphones level set
to minimum. Avoid continued high listening
levels in the headphones or any other earpiece.
2-TRACK Output
The 2-track output is sourced from the main LR mix.
The factory default setting is post master LR faders.
If you want to source pre-fader then replug the
internal jumper links on the LR MIX circuit board as
shown below. For stereo recording from a three
channel LCR mix, or by creating a new balance
from the groups, use the MATRIX outputs instead.
