This switch turns the 48v phantom power On/Off for the 3 pin XLR

48V phantom power is used to power condenser microphones and DI
boxes.

make sure that the Main and Monitor Master Volume
controls are turned down fully before switching on the
48V phantom power.
(13) Graphic Equalisers
The Graphic Equalisers are divided into 7 frequency bands. Each frequency
band can be used to either ‘ cut ’ or ‘ boost ’ the Main Output signal by up
to 10dB. One is in the main (stereo) path, the other is in the monitor
path.
They are very useful for compensating for poor room acoustics or
improving the performance of your loudspeakers.
