5. TAPE OUT

Use these stereo jacks to capture the entire
performance to tape. The signal at these jacks
is the main mix, post-MAIN INSERTS (13) and
post-MAIN MIX FADER (72). Signals at these
jacks will depend on the levels set by the main
mix fader.

Tip = hot, sleeve = shield

6. TAPE IN

Patch the outputs of an intermission enter-
tainment device here. Any line level mono or
stereo device can be used: tape, CD player,
television audio, etc. See TAPE RETURN TO
PHONES/C-R (69) and TAPE RETURN TO
MAIN MIX (71) for more information.
When connecting a mono device (just one
cord), use a "Y-splitter" RCA adapter. It turns a
mono cord into two cords; so both the left and
right tape input jacks can be patched. This
adapter is widely available.

7. SUB INSERTS

With nothing plugged into these jacks, the
subgroup mix goes straight through the SUB-
GROUP FADER (60) to the SUB OUTS (8).
With an effects device plugged into these jacks,
the subgroup mix leaves the mixer, goes
through the effects device and back into the
mixer's subgroup faders.
Use these jacks to send a subgroup mix
through a compressor, graphic equalizer or
similar device. Since the insert is before the
subgroup faders, moving the fader will not
16
alter the level sent to a compressor, thereby
preserving the original signal's characteristics.
These unbalanced insert jacks are wired ex-
actly the same as shown for INSERT (3) on
page 15.

8. SUB OUTS

TIP
In live sound applications, these jacks can
be patched into secondary amplifiers, allowing
levels to be controlled, independently of the
main mix, via the SUBGROUP FADERs (60).
Alternatively, the MAIN OUTS (12) (16)
could feed the amplifiers while the subgroups
feed a recorder.
In studio applications, these outputs can be
used as four separate paths to feed four or
more tracks of a multi-track recorder.
See 1-2 & 3-4 (40) and L/R ASSIGN (59) for
more information.
Accepts 1/4" TRS balanced or 1/4" TS unbal-
anced plugs, see page 14 for wiring details.

DOUBLE BUSING

Although this is a "four-bus mixer," meaning
there are four separate subgroups available, it
can be used to feed all eight tracks of a multi-
track recorder, thanks to a trick called Double
Busing.
SUB OUTS 1 and 5 carry the same signal,
and so do 2 and 6, 3 and 7, 4 and 8. Patch these
outputs into the corresponding inputs of your
multi-track recorder.
To record onto track 1, for example, put
track 1 in record mode, but leave track 5 in
safe mode. To record onto track 5, put track 5
in record and put track 1 in safe mode.
