A sound desk is a piece of equipment which blends and controls the volume on a number of input signals, routing the resultant mix to the required destination.
Please click on an area of the desk to find out more about it.

Mono channel inputs
Each row allows the control of a single mono input, enabling the signal to be passed to other parts areas on the desk. Most large desks have around 24 sets, allowing the input of 24 mono signals.

Stereo channel inputs
Each row is exactly the same as a mono channel input but they accept stereo signals which are then distributed to the rest of the desk in the same manner. Most desks have around 2 sets, allowing the input of 2 stereo signals.

Subgroups
By grouping a number of signals together, their volume can be controlled on one fader, enabling easier control of the sound.

Mix output
This is the main output of the desk, where signals are mixed into two channels that can then be outputted via the main output faders.
