40. Assign to Main Button
When the “Assign to Main” button is engaged, the USB/2T
Return and Alternative 3-4 signals can be selected by using the
corresponding buttons, and are, intern, sent to the Main L-R
and Control Room mixing buses via the Control Room / Submix
control. This can come in handy when you want play a CD during
intermission in a live show, as this allows users to send the signals
from the USB interface, 2T RTN and/or ALT 3-4 to the main left
and right outputs. If you have the Main L-R or AUX 1 buttons on
the Control Room Source section engaged, the corresponding
signals will not be sent to the control room and headphones output
by the use of this button.
41. Control Room / Submix Control
This control is used to adjust the audio level of the Control
Room feed, which is sent to both the Control Room outputs (for
monitoring, acting as side fill or other purposes) and Phones
outputs (to be used in conjunction with headphones for monitoring
purposes). It also acts as the “Submix” control, which allows the
user to adjust the level of the signals selected by the Control Room
Source when the Assign to Main button is engaged.
42. Main Level Fader
This 60mm fader is final level control for the main left and right
audio feed, sent to the Main L and R output.
43. Level Meter
The stereo 8-segment level meter gives an accurate indication of
when audio levels of the selected Control Room source(s) reach
certain levels. It is suggested for the maximum use of audio to
set the various levels controls so that the Peak LEDs flash only
occasionally (and perhaps it is better if you ensure the level stays
around a pinch below that).
44. +48 Indicator
The +48 Indicator illuminates whenever the Phantom Power
switch is activated.
45. Power Indicator
The Power Indicator will light up when the power of the mixer
is on.
