Auxes 1 & 2
Each of these controls sends a signal to an auxiliary bus. The signal is
sourced pre-fade which means that the level is independent of, and un-
affected by the fader. Auxes 1 & 2 are primarily used for foldback moni-
toring purposes, as the fader does not affect the level.
These sends are affected by the Mute switch, so muting the channel will
also mute the Aux sends.
The control varies the signal level to the bus from off (fully attenuated)
to +6dB, with unity gain at the arrow.
There are master level controls for all of the Aux outputs situated in
the master section of the mixer.
Auxes 3 & 4
The source for Aux sends 3 & 4 is post-fader. They are also muted by
the Mute switch. Auxes 3 & 4 are primarily used for effects sends.
Jumper Link Options.
There are optional positions for fitting link wires on the mono input
channel circuit boards to change Auxes 1 & 2 to be post fade and
Auxes 3 & 4 to be pre-fade sources.
These are not easy to get to however, and involve taking out the chan-
nels from the mixer to access. We will try to improve this with future
updates to the circuit board.
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 ste-
reo outputs.
PFL Switch
The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL
bus and subsequently to the headphones and the main left & right me-
ters. Used for checking the audio signal before raising the fader or un-
muting the channel.
Mute Switch
This mutes or cuts the signal to the main L-R bus and the Auxes. A
rectangular LED illuminates to show the Mute switch is pressed.
L-R Routing Switch
The L-R switch connects the post-fade signal to the main L-R
mix bus via the pan control. 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.
MONO INPUT CHANNEL
Signal & High level indicators
The Signal LED illuminates dimly at a threshold of –14dB 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 HI signal LED illuminates when the signal just after the EQ IN
switch is within 5dB of clipping.
