PAN
The pan control adjusts how the signal from the mono input channel is
shared between the left and right buses and subsequently the main stereo
outputs, similarly to pairs of Groups. Set to the mid position, equal amounts
of signal are fed to left and right, with pan set to L, none is sent to the Right
bus.
PFL Switch
The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL bus
and subsequently to the headphones and the main L R meters. Used for
checking the audio signal before raising the fader or un-muting the channel.
15
Mute Switch
This mutes or cuts the signal to the buses and the Direct Out. A rectangular
LED illuminates to show the Mute switch is pressed.
14
Routing Switches
The routing switches connect the post-fade signal to the mix buses via the
pan control for the main LR bus and the group buses. For minimum noise
from the mix bus summing amplifier, leave the switches in their up positions
if the channel signal is not required on the bus.

The Signal LED illuminates dimly at a threshold of –16dB nominal level and
gets brighter with higher level signal. The source for the signal & peak LED’s
is just after the EQ IN switch.
The PK! LED illuminates when the signal just after the EQ IN switch is
within 5dB of clipping.

Fader
The 100mm fader affects the level of the channel signal to the left & right,
mono and group buses and Auxes 5 & 6. Also Auxes 3 & 4 if switched to
post-fade. There is 10dB of gain at the top and the unity gain position is
marked by “0”.
