the performer's Cue mix for overdubbing
which requires the ability to combine the
already recorded tracks with the new
material. By monitoring the recorders
outputs while in the Sync mode, you will
have both the new and pre-recorded
material available for independent Cue mix.
When checking the overdub, the Cue
system will now be fed all of the recorded
tracks at relatively the same mix levels that
occurred during the recording.
d.
Ll NE - Selects the Channel's line input.
The Ll NE position is very useful as a way
to return submixes or effects into the AUX
system.
Each of these position can be used for various
reasons, and this ability to select the signal
source can be extremely beneficial during
complex mixing situations.
eiNSERTion Jack
This
1
/4" Phone jack is actually two connectors
in one. The jack is a stereo "break" design and
is wired in a standard TIP-RING-SLEEVE
configuration. The channel's signal, or SEND,
is wired to the connectors TIP contact. The
INSERT or RECEIVE, which allows outside
signals back into the channel path, is wired
to the RING (middle) contact. The shield
connection for both signals is the SLEEVE.
The jack contains a mechanical switch, or break,
which opens, or "breaks", the normal contact
between the TIP and RING portions, whenever a
plug is inserted into the jack. This mechanical
switching technique is called "normalling". A
connector is "normalled" if it provides the signal
to be disconnected when a plug is inserted, but

This jack is located on the rear panel just above
the MIC IN connector.

E FFECT Send Control
The EFFECT control is similar to the AUX
controls, except it cannot be switched to receive
signals from various points. The EFFECT signal
is always derived post-FADER and ON.
e Channel Assign Switches
The five push-button switches allow the
se­
lection of each of the four PROGRAM busses
independently plus the STEREO MASTER
busses. Any combination of busses can be
selected simultaneously. The switches receive
their signal after the channel PAN control,
with the PROGRAM
1 &
3 and the STEREO
LEFT busses receiving the output from the PAN
LEFT, while PROGRAMS
2 &
4 and STEREO
RIGHT receiving the output of PAN RIGHT.

0 PAN Control
As described above, the PAN (short for "pano­
rama") control acts
as
a left-to-right balance
device for "placing" the channels signal in the
stereo spectrum. Placing the PAN control in the
center or
1 2 o'clock position sends the signal to
both the left and right busses equally.
