(8) Main Master Volume Control
This control determines the overall level that is sent to the internal
amplification and to the Main Output socket.(19)
(9) Mon (PHONES) Master Volume Control
This control determines the overall level that is sent to the Monitor
Output (Mon Output) and Phones socket.
(10) Phantom 48V switch
This switch turns the 48v phantom power On/Off for the 3 pin XLR
sockets on channels 1-4. When the switch is turned On the red LED
will illuminate.
48V phantom power is used to power condenser microphones and DI
boxes.
NB! To avoid possible damage to your loudspeakers,
make sure that the Main and Monitor Master Volume
controls are turned down fully before switching on the
48V phantom power.
(11) Graphic Equaliser
The Graphic Equaliser is divided into 7 frequency bands. Each frequency
band can be used to either ‘cut’ or ‘boost’ the Main Output signal by up
to 10dB.
The Graphic Equaliser is very useful for compensating for poor room
acoustics or improving the performance of your loudspeakers.
(12) To Main/To Mon switch (GigRac 600 only)
This switch determines which signal path is sent to the Graphic Equaliser.
Normally the Graphic Equaliser operates on the Main Mix output path
(To Main) but it might be desirable for some applications to have the
Graphic Equaliser assigned to the Mon Mix output path.
