MONITOR SENDS

These controls route the input channel signal to any one or more Monitor busses and the associated Monitor Outputs, allowing a number of unique monitor mixes to be created. The sends are arranged as a group of mono sends (1-8) and two stereo pairs (9/10 & 11/12). Each group of sends is normally POST-FADE, POST-EQ but may be switched to PRE-FADE, POST-EQ by pressing the corresponding PRE switch. All sends are muted when the MUTE switch (9) is pressed. Sends 9-12 are arranged as two stereo pairs, with a send level control and a PAN control to position the channel signal in the stereo image. With the PAN control centered, the signal is fed equally to both sends in the pair. You get most control when the input Sensitivity is set up correctly, giving maximum travel on the send controls. See the `Setting Up & Troubleshooting’ section on page 8 for help in setting a suitable signal level.

MUTE

All monitor sends are disabled when the MUTE switch is down, and the associated amber LED illuminates to show that the switch is pressed.

FADER

The FADER provides overall level control of any Monitor Sends which are selected as post-fade. You get most control when the input Sensitivity is set up correctly, giving full travel on the fader. See the `Setting Up & Troubleshooting’ section on page 8 for help in setting a suitable signal level.

SIGNAL LED

This green LED illuminates to show that a signal with a level greater than -20dB is present in the channel.

PFL/PEAK

When the latching PFL switch is pressed, the pre-fade, post-EQ signal is fed to the headphones and engineer’s wedge outputs, replacing the selected wedge source and illuminating the SOLO/PFL LED on the Master section to show that a PFL is active. The adjacent red LED lights to identify the selected channel. This is a useful way of listening to any required input signal without interrupting any of the monitor sends, for making adjustments or tracing problems.

When the PFL switch is released the LED serves as a PEAK indicator which illuminates approximately 4dB before clipping to give warning of a possible overload. The signal is sampled at two points in the EQ section and at the Insert Send.
