This send can be pre-fade and used in the same way as Aux Sends 1 & 2 for Foldback or as a Monitor feed, but
for Effects it is more appropriate for the Aux Send to fade up and down with the fader (POST-FADE). A Master
Section AUX3 PRE switch allows you to switch all channel Aux 3 sends from pre- to post-fade across the whole
mixer as required. The send is fed from a mono sum of the channel Left and Right signals.
AUX SENDS 4-8
These are always POST-FADE and would normally be used to drive effects processing units which are fed back
into the mixer and which must fade out with the input channel.
Aux 4 is derived from a mono sum of Left and Right, while the 5/6 STE knob feeds the channel signal via the BAL
control (see below) as a stereo pair to either Aux outputs 5 & 6 or, with the 7-8 switch pressed, to Aux outputs 7
& 8. This is particularly useful to feed the growing number of stereo effects units now available.
BALANCE
This control sets the amount of the channel signal feeding the Right and Left MIX outputs, 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 mix. Unity gain is provided by the control in the centre-detented position.
ON Switch
The ON switch enables all post-fade outputs from the channel when pressed.
PFL
When the latching PFL switch is pressed, the pre-fade signal is fed to the headphones or monitor outputs, replacing
the selected source (either Mix or Tape Return). The PFL/AFL LED on the Master section illuminates to warn that
the headphones, monitor outputs and right PPM meter are now responding to the PFL/AFL selection. This is a
useful way of listening to any one or more signals without interrupting the main mix, for adjusting signal quality or
simply to check that it is there! You would also use the PFL switch to check the input level as explained under
‘Initial Setting Up’.
FADER
MASTER SECTION - AUXILIARY MASTERS
AUX 3 PRE
The input channels provide both Pre- and Post-Fade AUX 3 sends which may be selected desk-wide on the Master
Section. Press the AUX 3 PRE switch to make all of the AUX 3 Sends on the channel strips PRE-FADE. This
means that they will all be unaffected by the position of the channel faders or the ON switches, making them ideal
for FOLDBACK or MONITORING. Since this button affects all the channels on the mixer, its importance is
highlighted by a mauve cap colour.
When the switch is released the AUX 3 Sends are all POST-FADE, and will fade up and down with the channel
faders. This is more suitable for effects sends which need to fade out with the associated source.
MASTER LEVEL
Each of the Auxiliary Send busses is provided with a rotary master level control. Aux 1-4 are individual controls,
while Aux 5/6 and Aux 7/8 are stereo pairs. A MONO switch is provided to turn Aux 7/8 into summed mono outputs
if a greater number of mono sends is required. Note that in this instance the position of the channel PAN and BAL
controls may affect the Aux 7/8 output level.
