This section is primarily used for controlling the volume of a signal and sending elsewhere to be mixed through to the front-of-house speakers.

Pan control Like a balance control on your hifi, this determines the left and right balance of the signal sent to the groups and main mix. On/Off (sometimes known as mute) This button turns the channel on or off With this muted, the channel sends no signal to the main mix, groups or auxiliaries. Fader This control determines the volume of the signal sent to the mix and groups. Mix/Groups buttons These determine where you send the signal after it has been affected by the fader. If you have the channel on, make sure you remember to press the mix button, otherwise the signal won’t be sent to the main mix and you won’t hear anything! PFL pre-fade-listen (sometimes known as SOLO) This button shows you the level before the fader, and allows you to set the correct gain level. Pressing the PFL button displays the level on a series of level LEDs on the desk, but doesn’t affect any other part of the desk. It also doesn’t matter if the channel is switched off, PFLing still works. See How to set the correct gain
