BAL positions the channel signal within the stereo image or between L-R and
the groups when the routing switches are selected. The centre position is
detented for quick resetting.
MUTE switches the signal off when pressed regardless of fader position.
Muted channels are indicated by red LEDs. The meter continues to indicate
pre-fader channel activity.
A 4 LED CHANNEL METER shows signal activity. The green SIG LED
indicates signals greater than -20dBu, yellow ‘0’ and ‘+6’ represents normal
operating level, and red PEAK warns of potential overload 5dB before clipping.
Set the channel signal so that the meter averages between ‘0’ and ‘+6’. Back
the gain off if the red peak LED flashes.
Pressing PFL lets you listen to the channel pre-fader signal on headphones
without interrupting the main console outputs. The signal level is shown on the
L-R bargraph meters. In this way each sound can be correctly lined up and
checked at any time.
L-R, 1-2, 3-4 routing switches feed the channel signal to L-R mix and groups
1-2, 3-4. Use the pan control to route to individual groups, ie left to route to L,
1, 3 and right to route to R, 2, 4. In this way subgroups may be set up in mono
or stereo to feed the main L-R mix.
A 100mm FADER provides +10dB boost above the normal ‘0’ operating level.
All post-fade aux send levels are dependent on the level of the fader.
