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

" jacks are usually patched to the
inputs of your control room amplifier or a
headphone distribution amplifier.

PHONES OUTPUT
The 1604-VLZ
PRO’s stereo
1
/

" 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
CTL ROOM/PHONES
knob
all the way down before connecting head-
phones. 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
®
#274-511, for instance).
Do not attempt this with any other outputs on
the 1604-VLZ
PRO.
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).
