room. This lets performers increase their
level in the headphone mix without an
engineer getting involved. The Model 38s
circuitry was carefully designed to not
interfere with the talent audio as it passes
through.
The Model 38 has all the functions of the
Model 35, plus it provides personal mix
controls. The power present LED should
be lit whenever the Model 38 is connected
to an operating Model 50. You can plug in
one or two pairs of headphones with a
total impedance of 75 ohms or greater.
The Cue Mix Level control sets the head-
phone output level for the signal coming
from the Model 50. The Cue Mix Stereo/
Mono button switches both headphone
outputs between a stereo and mono
(L+R) feed of the cue mix.
The Model 38 allows connection of a
Stereo or Mono talent signal at micro-
phone or line level. If your talent source is
stereo, connect it to the In Left/Mono and
In Right connectors and set the Talent
Stereo/Mono button for stereo operation.
With a mono source, use only the In Left/
Mono connector and set the Stereo/Mono
button for mono operation. This will feed
the mono talent source to both left and
right headphone channels. Connect loop
through cables as needed for feeds to the
control room.
The Talent Mic/Line button is used to
select an input sensitivity level for the
talent source. When you connect a micro-
phone or direct box, select Mic. When
keyboards or other preamplified sources
are connected, select Line. The expected
signal level in the Mic position is 40 to
60dBu. In the Line position its 10 to
+10dBu. If you are unsure of your signal
level, start with input sensitivity set for
Line. If the output level is not sufficient,
turn down the level control, switch to Mic,
then listen as again you raise the level
control.
The Talent Level control works just like
you would guess: turn it up for more talent
signal in the headphone mix, and turn it
down for less. The Talent and Cue Mix
level controls work like a mixer for the
headphone outputs, so you can have
any level you want of either source in
the headphone mix.
Troubleshooting
If youre having problems getting the
StudioComm system up and running, this
section can help. If you havent read the
other sections of this guide, you should
do so before proceeding.
If the Model 51 Doesnt Work At All
Your StudioComm system was supplied
with a 5-conductor DIN-type cable that is
used to connect the Model 51 Control
Console to the Model 50 Central Control-
ler. This cable has an important character-
istic; it implements all five conductors.
This means that all five pins on each plug
connect to each other using a length of
5-conductor cable. If you choose to use
your own cable its easy to get in trouble;
many MIDI cables only have three conduc-
tors! You must use a 5-conductor MIDI-
style cable or the Model 51 will not power
up and function. Five conductor MIDI
cables are not hard to find, but you must
ask for them and ensure that you get what
you asked for. Be warned!
