8.2.3. STEREO CHANNEL LINE IN
Stereo inputs ST1 and ST2 feed channel 15, and ST3 and ST4 feed channel 16 respectively, or can
be routed directly to LR. These inputs use TRS jacks. ST1, 3 are unbalanced, ST2, 4 are balanced.
Unbalanced inputs automatically connect the TRS ring to ground when working with balanced
sources. The L input is normally through the R socket to accept mono signals on a single jack.
8.3. INSERT
A single 3-pole TRS insert jack carries the unbalanced insert signal
for each mono channel and main mix output. Tip = send, ring =
return, Sleeve = common ground. The channel inserts are post
HPF, pre EQ and operate at 0dBu/0,77V. The group (AUX) and LR
mix inserts are pre-fader and operate at -2dBu/0,62V. Use these to
patch in line level signal processing equipment such as
compressors, outboard EQ, delay units and so on. The wiring of a suitable cable is shown in the
diagram.
8.4. DIRECT OUTPUT
Each mono channel direct output is available on an impedance balanced TRS jack providing a line
level signal operating at 0dBu/0,77V. The output is set pre-fade.
8.5. LAMP
The console has one 4pin XLR socket to plug in standard 12V gooseneck lamps to
illuminate the operating surface when working in a dark environment. Only use the
lamps intended for this purpose. We recommend the LED lamp with cool white
LED illumination and a built in dimmer.
8.6. GROUP; L; R; M OUT
The main console mix outputs are on
electronically balanced XLR. These
produce the professional standard
+4dBu/1,23V when the meters read 0,
and provide to a maximum
+25dBu/13.77V. The L and R outputs
typically feed the house PA system in live sound mixing, or a 2-track recorder in studio mixing. In
monitor mode, these outputs reverse with the AUX TRs jack connections.
