STEREO RETURNS

			There are four Stereo Returns, which have similar controls but different routing
			configurations to provide the maximum flexibility. Each Return has an
			unbalanced stereo input on 3-pole ’A’ gauge (TRS) jacks. If a mono source is
			to be used, plugging into the Left jack automatically feeds the signal equally to
	2		both sides of the Return.
		1	LEVEL
	1		The LEVEL control sets the overall signal level, and enough gain is available to
			match both +4dBu and -10dBV sources. Rotation clockwise increases the gain
	3		of the input.
	4	2	AUXILIARY SENDS
			Each Return may access Aux 1 (Pre-fade) and one of the post-fade sends.
1	1		Returns A & C feed to Aux 3 and Returns B & D feed to Aux 4. The controls
			should be turned fully anticlockwise when not in use.
4	4
		3 BALANCE
			This control sets the amount of the channel signal feeding the pairs of Groups
			or Mix, allowing you to balance the source in the stereo image. When the control
			is turned fully right or left you feed only that side of the signal to the destination
			selected by the Routing switch (see below).
		4 PFL
	5		When the PFL (Pre-Fade-Listen) switch is pressed a mono sum of the pre-fade
			signal is fed to the headphones or monitor output, replacing the selected source.
			The PFL LED on the Master section illuminates to warn that the headphones,
			monitor and right bargraph meter are now responding to the PFL/AFL selection.

5 ROUTING

This switch selects either a pair of Groups (switch released) or Mix (switch pressed) as the destination for the Stereo Return signal after it has passed through the BAL control. Returns A & B route to Groups 1 & 2, and Returns C & D route to Groups 3 & 4. The left return signal feeds the odd-numbered Group or Mix Left, while the right return signal feeds the even-numbered Group or Mix Right.
