This method is exactly
the same as the double-
busing feature found in
other mixers. Built-in double
busing is nothing more than
Y-cords living inside the mixer instead of
hanging out the back. If we had room for the
extra jacks, we would have thrown them in,
but we don’t, so we didn’t. Sonically, there is
no difference whatsoever.
Y-cord advice: Do not use the stereo “head-
phone-to-left/right” splitter adapters. Use the type
that send the same signal to two places; the tip of
the source plug feeds the tips of both destination
plugs (Radio Shack
® #42-2150, for instance.)
C-R OUTS (CONTROL ROOM OUTPUTS)
These 1 /
4
" jacks are usually patched to the
inputs of your control room amplifier or a
headphone distribution amplifier.
To learn
how signals are routed to these outputs: .
To wire your own cables: .
PHONES OUTPUT
The CR1604-VLZ’s stereo 1 /
4
" phones jack
will drive any standard headphone to very loud
levels. Walkperson-type phones can also be
used with an appropriate adapter.
To learn
how signals are routed to these outputs: . If
you’re wiring your own cable for the PHONES
output, follow standard conventions:
Tip = left channel
Ring = right channel
Sleeve = common ground
WARNING: When we say
the headphone amp is
loud, we’re not kidding. It
can cause permanent ear
damage. Even intermedi-
ate levels may be painfully loud with some
earphones. BE CAREFUL!
Always turn the C-R/PHONES knob all the
way down before connecting headphones. Keep
it down until you’ve put the phones on. Then
turn it up slowly. Why?
“Engineers who fry
their ears find themselves with short careers.”
TAPE OUTPUT
These unbalanced RCA jacks tap the MAIN
MIX outputs to make simultaneous recording
and PA work more convenient. Connect these
to your 2-track recorder’s inputs.
To learn how
signals are routed to these outputs: .
Mono: If you want to feed a mono signal to
your tape deck or other device, simply use the
1 /
4
" MONO output jack . Alternatively, use
an RCA Y-cord to combine the TAPE OUTPUT
jacks (Radio Shack ® #42-2435, for instance).
Do not attempt this with any other outputs on
the CR1604-VLZ.
TAPE INPUT
These unbalanced RCA jacks are designed
to work with semipro as well as pro recorders.
Connect your 2-track tape recorder’s outputs
here, using standard hi-fi RCA cables.
To learn
how signals are routed from these inputs: .
Use these jacks for convenient playback of
your mixes. You’ll be able to review a mix, and
then rewind and try another pass without
repatching or disturbing the mixer levels. You
can also use these jacks with a portable tape
or CD player to feed music to a PA system
between sets
.
WARNING: Pushing TAPE
TO MAIN MIX in the out-
put section can create a
feedback path between
TAPE INPUT and TAPE
OUTPUT. Make sure your tape deck is not
in record, record-pause or input monitor
mode when you engage this switch, or
make sure the
TAPE IN level knob is fully
counterclockwise (off).
