19 AUX SEND This controls the overall output level at the AUX SEND jack, of the mix of signals
derived from the AUX controls on the input channels.
20 TO AMP This is the master volume control for the built-in stereo 2x300W power amplifier. The
LEFT & RIGHT FADERS, or the MON FADER (depending on the selection made on
the L-R/MON switch below) must be raised to allow this control to work.
21 L-R/MON This button is for selecting whether the left and right busses or the MON buss are
routed to the built-in amplifier.
22 L-R/MON This button is for selecting whether the left and right busses or the MON buss are
routed to the PHONES socket.
23 PHONES This is the output volume control for the headphones.
24 PHONES socket. For stereo headphones. 0.25" stereo jack wired Sleeve = Ground, Ring =
Right, Tip = Left. The headphone amplifier is designed to cater for headphones with a
minimum impedance of 400 ohms.
NOTE : The LED bargraphs are connected to the main (left/right) outputs of the mixer section
and are calibrated to indicate an output level of 0dBu (.775V) when the first red LED is
illuminated.
The amplifier section gives maximum output with an input signal of 0dBu (.775V), so
when the "To Amp" control is turned fully clockwise, red LEDS are accompanied
by distortion at the speaker outputs.
When the "To Amp" control is set below 10, there is no direct relationship between the
bargraphs and the amplifier output.
