the stereo return fader and MUTE button have no effect on the level. In AFL
mode, the full stereo signal is heard. In this case, both the stereo return fader
and MUTE button will affect the signal heard.
M – Pressing the M (MUTE) button mutes the stereo return. This will mute the
return’s feed to the subgroups, the L-R Master output, Aux. sends 5 and 6 and
any AFL monitoring. The exception is PFL monitoring, which remains active. An
adjacent red LED illuminates to confi rm that MUTE is applied.
Fader – a 100 mm plastic conductive fader with a red knob adjusts the overall
stereo return level. The pre-fade stereo return signal may be metered at the top
of the strips, provided the RET/AUX button is set to RET.

LINE IN – A rear panel input (‘LINE INPUT’) to the L-R Master is provided; this
is useful for connecting a CD player, laptop or similar for pre-show music, and
avoids the use of a stereo channel or return for a source not used during the
show. The LINE IN control sets the level of this input.
MONO – pressing the MONO button sums the left and right legs of the L-R
Master output. The left and right outputs will have the same signal. An adjacent
green LED illuminates to warn that MONO has been selected.
Meters – a dual, 10-segment LED bargraph meter indicates the level of the L-R
Master output. The metering point is post-fade, but pre-mute. It is also post the
MONO button. Note the bottom LED is labelled SIG, and illuminates at a signal
level of approx. -36 dBu. The LEDs are colour-coded as follows:
yellow: -24 dBu to +12 dBu
red: +18 dBu
green: SIG
PFL – pressing the PFL button routes the L-R Master signal to the internal
PFL/AFL system so that it may be monitored on local speakers or headphones
connected at the MON OUT or HEADPHONES connectors respectively. The
signal continues to route normally while the PFL button is pressed. An adjacent
green LED illuminates to confi rm that PFL/AFL is active.
Monitoring of the L-R Master output may be either pre-fade (PFL) or after-fade
(AFL); the mode is selected globally from the Master section (see “AFL Mode
on page 29). In PFL mode, the signal heard is a mono sum of the L and R
legs, and the master fader and MUTE button have no effect on the level. In AFL
mode, the full stereo signal is heard; the channel fader setting will affect the
level of the signal heard, but the MUTE button will have no effect.
M – Pressing the M (MUTE) button mutes the L-R Master output. An adjacent
red LED illuminates to confi rm that MUTE is applied.
Fader – a 100 mm plastic conductive fader with a black knob adjusts the L-R
Master output level.
