Studio Technologies IFB Plus 2005 - Manual (Page 9)

Model 2 User Guide Issue 8, December 2005
Studio Technologies, Inc. Page 9
Each Model 32 and Model 33 contains both
a male and female XLR-type connector,
allowing simple “loop through” connection
of multiple units. Up to four talent amplifiers
can be connected to, and powered by, a
single Model 2 Central Controller. On each
talent amplifier the audio output signal is
provided on a standard ¼-inch 2-conduc-
tor phone jack. An LED on each unit lights
whenever power is present, providing setup
assistance and user confidence. Identical
in size, each is housed in a lightweight, yet
rugged, aluminum housing. A belt clip al-
lows it to be attached to belts, clipboards,
scabbards, pizza boxes, production assis-
tants, etc. An optional mounting adapter is
available, allowing a Model 32 or 33 to be
installed in a permanent location.
The Model 32 is intended for use by on-air
personnel, and contains a source switch,
along with an output level control. Either
IFB channel 1 or IFB channel 2 can be sent
to the talent, along with the desired audio
“volume.”
The Model 33 is unique in that a “mix” of IFB
channels 1 and 2 can be created. Two level
controls, along with a source select switch,
allows camera and production personnel to
hear IFB cues from either or both channels.
This allows IFB signals intended for both
technician and talent to be simultaneously
monitored.
Installation
In this section you will be installing a Model
2 Central Controller in an equipment rack.
In conjunction with the Model 2, up to four
Model 22 Access Stations can be installed.
In addition, wiring can be installed for up to
four Model 32 and 33 Talent Amplifiers.
Internally, the Model 2 has no configuration
switches or trim pots to set. However, there
are several reasons why you may need to
access the “guts” of the unit:
• The factory-selected AC mains voltage
will be either 120 or 220/240 V, depend-
ing on the shipping destination. It may
need to be revised for your installation.
• From the factory, the Model 2 is set to
mute program audio when an interrupt
takes place. If desired, a program “dim”
function, rather than mute function, can
be
implemented.
Refer to the Technical Notes section for
details on revising these conditions.
In addition to the above situations, you may
want to take a look inside and familiarize
yourself with the unit on the rare occasion
that it may need service. (The people here
in the marketing department taught us never
to say a unit may need to be fixed—service
is much nicer!) We are proud of how the
“guts” of the Model 2 look and how it is
constructed so we encourage you to take a
look!
On a more serious side, removing the Model
2’s cover with the AC mains cord connected
exposes you to hazardous voltages.
Warning: Never remove the cover with-
out disconnecting mains power. We
make the assumption that anyone gain-
ing access to the inside of our products
meets the requirements for “qualified ser-
vice personnel”—including knowledge of
safety precautions.
