switch allows a post-fader signal to be sent to the HEADPHONE OUTPUT (42) and the
AFL/PFL LEVEL DISPLAY (45). A yellow LED above the switch indicates AFL (post-fader)
engagement.
(47) L & R MASTER FADERS
These controls determine the level of the signal sent to the LEFT and RIGHT outputs
respectively. As with all faders, the optimum setting is at unity gain (0).
(48) POWER LED
This green LED will illuminate when power is applied to the RQ 4300, indicating the unit is on.

(49) L, R, MONO INSERT
These 1/4" stereo (TRS) jacks, provided on the LEFT, RIGHT and MONO channels, allow an
external device to be inserted into the signal path, pre-MASTER FADER. The tip carries the
signal being sent and the ring is the signal return. A switch in the jack connects the send to
the return if no plug is inserted. The signal must be returned to this jack when this feature is
used. Failure to return the signal will result in no output.
(50) L, R, MONO UNBAL (UNBALANCED OUTPUT)
These 1/4" jacks allow output of an unbalanced signal and are provided for the LEFT, RIGHT
and MONO channels.
(51) L, R, MONO BAL (BALANCED OUTPUT)
These XLR connectors allow output of a balanced signal and are also provided for the LEFT,
RIGHT and MONO channels. The unbalanced and balanced outputs can be used
simultaneously, but both output levels are controlled by the corresponding MASTER FADER.
(52) RETURN INPUTS
These 1/4" balanced (TRS) high-impedance inputs can be used as stereo or individual
returns. Designed for effects return, they can also be used as additional stereo inputs. The
MONO/LEFT input provides signal to both inputs if no connector is attached to the RIGHT
jack. The tip is the positive input for both balanced and unbalanced use.
