Talent Amplifiers
Warning:
Protect your ears! The Studio-
Comm talent amplifiers are capable of
driving headphones to extremely high
sound pressure levels. Hearing experts
advise against continuous extended
play, especially at high levels.
Model 35 Talent Amplifier
The power present LED should be lit when-
ever the Model 35 is connected to an oper-
ating Model 50. The Model 35 has a Level
control and a Stereo/Mono button. You can
plug in one or two pairs of headphones with
a total impedance of 75 ohms or greater.
Turn the knob to the output level you want
and select stereo or mono by pressing the
button. Both headphone outputs are con-
trolled by the one level control. The Mono
button sends L+R to both the left and right
output.
Model 38 Talent Amplifier
The Model 38 has the unique ability to pro-
vide a personalized headphone mix for the
in-studio talent. The performer’s audio can
be connected to the talent inputs
and pas-
sively looped through to the control room.
This lets performers increase their level in
the headphone mix without an engineer
getting involved. The Model 38’s 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
level to the headphones will be determined
by the slate level setting (not the talk to
phones level).
The talk to phones function is configured
to interrupt or to add to the selected head-
phone source. If interrupt is selected,
activating talk to phones disconnects the
selected headphone source and connects
communications audio. If add is selected,
activating talk to phones leaves the head-
phone source connected and adds (sums
or mixes) the communications audio.
You can independently set the output level
for the three communications functions.
To set the communications levels, press
and hold any one of the three buttons and
press the Communications Level buttons.
(If the talk to studio, talk to phones, or slate
buttons are set to latch, you won’t have to
hold them.) The LEDs above the buttons
will flash each time the level is increased
or decreased until you reach the top or
bottom of the range. At this point, if you
continue to press the Level button, the LED
won’t flash, indicating you’re at the top or
bottom of the eight-step level range. Note
that the 50Hz tone will always be 10dB
below the slate level.
Note that whenever the talk to headphones
button is pressed its level is always se-
lected, even if either or both of the other
talkback buttons are also pressed. The
talkback to headphones level always takes
priority. If the talk to studio and slate but-
tons are pressed at the same time, the talk
to studio level will have priority.
Headphone Level
The headphone output level is adjusted
directly at the Model 35 and/or Model 38
Talent Amplifiers. There is no headphone
level adjustment available on the Model 51.
