Stereo/Split Feed outputs:
1.1.1
The Model PIC-4000 IFB central Electronics has been upgraded
to the Model PIC-40005. The upgrage consists of a circuit
design change that permits all of the four IFB outputs to
feed two discrete audio channels ("Interrupt" & "NonInterrupt") to the new Model TR-532 Stereo/Split Feed Talent
Receivers. The two discrete signals, plus the DC operation
power, are sent to the TR-532 via 3-pin XL type connectors
and two conductor shielded cable (standard microphone
cable).
1.1.2
This upgrade in no way effects the PIC-4000B's operation
with TR-50 Single Channel Talent Receivers, which receive
only the "Interrupt" signal.
1.1.3
TR-50s and TR-532s should not be combined on the same IF1
output. However, if they are accidently connected to the
same output, no damage will result to the units or to the
system.
1.1.4
Each of the four IFB outputs can operate a maximum of four
TR 50U ing1e Channel Talvnt Receivers or two TR-532
Stereo/Split Feed Talent Receivers.
1.1.5
This upgrade eliminates the -SPC" Sportscaster/Two Channel
output" option, which provided the "Interrupt/Non-Interrupt"
outputs to two channel Talent Receivers via a 6-pin cable.

INTRODUCTION
A.
IFB System
During production of a program for transmission or recording, a
director or producer frequently needs to cue the performing
talent. This is done using Interrupt FoldBack, a type of closedcircuit intercom for sending program and cue audio on "IFB" lines
for the talent to monitor. The IFs line carries three signals:
program audio, cue audio, and the dip or mute control.
See the
signal flow diagram below.
Electronic control allows the
director to interrupt the program signal when addressing the
talent. IFB communications are one-way only -- from an access
location to the selected talent position.

Clear-Com's new stand-alone IFB components provide high
performance, cost- effective answers for applications where
regular intercom functions are not also required, or where space
constraints require compact, versatile packaging.
The simplest
stand-alone system consists of a PIC-4000, an MA-4, a PS-20 for
power and one to four TR-50 talent receivers.
This system will
permit cuing of one to four talent positions from only one access
location.

B.
Unit Descriptions
Clear-Com's stand-alone series of IFB components offers two types
of talent access station. The MA-4 has a built-in electret
gooseneck microphone and a pre-amplifier with line-level output.
It provides access to four talent positions.
Each AX-4 allows
access, from the same location, to an additional group of four
talent positions; it requires an external line-level signal for
its cue audio source.
The MA-4's cue audio and ALL control
signals will feed up to twenty-three AX-4's, so that only one MA4 is reqired at each access location. Each talent position may
be accessed independently, or simultaneously with any other(s).
The ALL button on the MA-4 simultaneuosly accesses all talent
positions of the MA-4 and each AX-4 extension unit fed from that
MA-4.

*A PIC-4000 unit is required for every four talent positions, or
fraction thereof.
For example, a system with five to eight
talent positions will require two PIC-4000s. The same IFB system
with three access locations will require three MA-4's and three
AX-4's, but will still need only two PIC-4000's.
The PIC-400
performs the program feed and interrupt functions for each talent
position, and also terminates the IFB lines.

THE PIC-4000
The connectors on the MA-4, AX-4, and PIC-4000 are arranged for
convenient interconnection as a stand-alone system. However, all
units' electrical characteristics are identical to those of the
integrated IFB systems on our standard broadcast intercom line.
So with suitable connector adaptors, both types of units may be
mixed in a system.

INSTALLATION
System Capacity
A system may have up to fifty access locations. Cue audio from
the MA-4 can drive up to twenty-three AX-4 units, thus permitting
a maximum of ninety-six talent positions.
In order to use the IFB system at its maximum capacity, two
factors must be considered:
system wiring (architecture) and
power requirements.
The MA-4 consumes a maximum of 180 mA (idle
current 140 mA), and the AX-4 consumes a maximum of 150 mA (idle
current 120 mA). Since the resistance of the conductors in the
interconnect cable may be on the order of five to ten Ohms per
1000 feet, care must be taken to avoid having too many stations
on one long cable run. For example, a system with two MA's on a
2000 foot cable which has 16 Ohms cumulative resistance in the
power conductor plus another 10 Ohms in the common conductor, the
voltage drop is a maximum of 9 V. If another two MA's were to be
added for the same cable run, the voltage drop would be an
unacceptable 18 V. Therefore the other set of access stations
would have to be connected on a separate cable run from the PIC4000.
To determine the number and type of power supplies a system
requires, add up the number of Unit Loads.
(1 Unit Load = 50 mA)
PIC-4000
= 1 Unit Load
MA-4
= 4 Unit Loads
four TR-50 = 1 Unit Load
AX-4
= 3 Unit Loads
A PS-20 has enough capacity for 20 Unit Loads, a PS-452 can
supply 40 Unit Loads.
Example: System #5 on page 5 has a total of 20 unit loads, so a
PS-20 has exactly enough capacity for this system.
B.
System Architecture
Two basic cabling methods for connecting the system may be used:
Daisy-Chain (or Loop-Through) and Hub.
Both methods may be
combined in any system. Since the PIC-4000 has only two IFB line
connectors,
a Hub-type system is limited to two branches unless
a special splitter box is used. Generally, resistance-buildup
effects and resultant voltage drop are worse when using the daisy
chain approach.
The "hub" approach minimizes voltage-drop
effects at the expense of greater cumulative cable capacitance.
Cable capacitance is not quite the problem it is in regular
intercom systems, because there is no sidetone null change, only
a degradation of high-frequency response.
Referring to the typical System block diagrams on page 5, only
System #2 is connected using the "hub" method; all other systems
are shown connected via the "daisy-chain" method.

noted in Section B, the
common (or ground) conductors must be kept at a minimum for
proper operation. Resistance buildup in the common conductor
will also increase crosstalk. Follow the diagram below for best
results in connecting the cable to the XLR connectors. Notice
that all four of the spare conductors in each pair are tied
and all shields are tied together
together to pin 2 (DC power),
to pin 1 (common). This arrangement minimizes resistance buildup
effects in long cable runs.
Clear-Com has ready-made cable in 25, 50, and 100 foot lengths to
fit your cabling and system architecture needs. The model number
is ICxx/6.

Note: the diagram shows the access stations for talent positions
5-8 connected in a "hub" from the second PIC-4000 while the
stations for the first group of talent positions (1-4) are shown
connected in the "daisy-chain" method. In practice, stations for
both groups of talents would be interconnected in the same manner.

Connect single channel talent
receivers to the PIC-4000 using
standard two-conductor mic cable. For a split-feed receiver, our
standard 2/4 channel interconnect cable (ICxx/6 can be used. If
custom cabling is made, refer to the diagram on page 8 for
pinouts. Notice that pins 5 and 6 are not used, and be sure to
keep the conductors for pins 3 and 4 in separate shields. Only
two conductors are necessary for the cabling between the power
supply and the PIC-4000(s).
If any section of this cable is more
than a few feet long, be sure that heavy-gauge wire is used.

The MA-4 and AX-4 may be mounted in a console or desk, or in a
standard 19" rack using the optional rack kit (CC# 820022).
Refer to the diagrams below for mounting dimensions when
installing in a desk or console.
There are no special
constraints on relative positioning of MA's and AX's, though it
is expected that the extension bus cable (the one with phone
plugs) will be no more than 10 feet (normally 18 inches long).
Be sure to make allowance for the XLR connectors to be plugged
into the back of each access station.

Set-Up and System Check
After Program Sources are connected, assign them at the PIC-4000
to the talent channels with the Program (Source) select switches
for each channel's interrupt (#3) and non-interrupt (#2) talent
feeds. Set the toggle handle up to select source #1, or down to
select source #2.
Set the attenuation or dip of the program feed during cuing with
the dip adjust trims (#4). They can be set from no attenuation
(fully CW) to greater than 50dB (fully CCW).
Before adjusting the Program Level trims at the PIC-4000, the
volume at the Talent Receivers must be adjusted (via the control
on the Receiver) for a comfortable cue audio level in the
earpiece or headset while someone is cuing that talent position
from one of the access locations.
The PROGRAM INPUT LEVEL trims (#l) permit use of program levels
ranging from -20dBv to OdBv. At full clockwise rotation, the
gain from program input to the IFB line is approximately unity.
So at maximum gain setting, a program level of -2OdBv will be
roughly the same volume on the IFB line as the cue audio. If the
program source level is around OdBv, the trims will have to be
set near full counter-clockwise rotation to match the cue audio
level on the IFB lines.
(NOTE: The numbers in
() refer to the diagram on page 3.)
The only adjustment possible at the MA-4 is a trim (+/- 5dB) of
the mic gain. Adjusting this gain should be necessary only in
unusual circumstances, because of the mic preamp's limiter.
III.
OPERATION
The system is operated by engaging the desired cue buttons on the
access stations. A control voltage on the IFB line causes the
PIC-4000 to dip the program feed to that channel so that the
cues given are understandable. (At an optional split-feed
receiver, the program is dipped only in the cue side; the other
side has continuous program with no cue.)
A.
Press the IFB button on the access station corresponding to
the talent position(s) you wish to cue, then speak into
the MA-4's microphone.
B. Press the MA-4's ALL button, and you simultaneously activate
every IFB line, including those on any accompanying AX-4
units.
The control voltage also causes the corresponding buttons at all
other access locations to be brightly lit, indicating which
channels are in use.

lbn Shooting
The table of troubles on the next page, which generally involves system
wiring, covers only the most likely problems. In any trouble-shooting
effort, keep these points in mind:
1)
2)
3)
4)
5)
6)
The power for all units in the system is routed from the power
supplies through the PIC-4000.
All access stations (MA's and AX's) and the talent receivers are
connected across the IFB lines in a bridging configuration (highimpedence)
Each IFB line is terminated by its associated PIC-4000. The
termination is about 220 ohms A.C., and approximately 5000 Ohms
D.C.
Three different types of signals are present on the IFB line:
a. Cue audio, which originates from an access station's mic
b. Program audio, from the associated PIC-4000, and
c. Interrupt control signal, a D.C. voltage which also
orignates at an access station.
The audio levels are approximately -15 dBv ref.O-.775VRMS),
and the D.C. control voltage is about +13 Volts.
The cue audio and ALL control signal for operation of the AX-4
stations at any given location are supplied by the MA-4 station
at that location.
