The IFB-104 is a 1-RU panel that directly connects up to four IFB feeds to the ports of a
digital matrix system. Individual or multiple IFB earbuds or headphones may be powered
directly from each connected matrix port. Alternately, an intercom power supply may be
connected, allowing the use of active personal IFB receivers, such as the Clear-Com
TR-50 or TR-532.
The IFB-104 does not require external power to drive its circuitry. Each channel has a
rear-mounted wet/dry switch, allowing either direct connection or powering via a party-line
intercom power supply. The signal from the matrix port is transformer-coupled to the
XLR-connector output.

The BAL-8 is a 1-RU interface containing eight 4-pair, transformer-isolated ports. Each port
handles two audio signals and two RS-422 data lines. The unit isolates the connection
between Matrix Plus 3 ports and peripheral devices such as two-way radios.
Each set of input/output connectors has its own slide switch, allowing the port to be placed
into No
rmal or Interface mode. In normal mode, the data pairs are unaected, while in
interface mode they are connected to indicate to the system software that a direct connection
is being made. Each channel has a pair of RJ-45 connectors for input and output.

The PIA-32 is a stand-alone, one-rack-space translator that converts Matrix Plus 3 ports to
Matrix Plus II ports. It allows existing Matrix Plus II systems, interfaces, and accessories to
be used with Matrix Plus 3 systems without modication. Each unit connects six Matrix
Plus II ports, interfaces, or accessories to the Matrix Plus 3 frame.
The PIA-32 translates the dierent call-signal protocols used by Matrix Plus 3 and II,
allowing trunking between systems. It also enables connections between the Matrix Plus 3
frame and the outputs of existing IMF-1 interface frames, and permits interface ID. Further,
it enables the connection of third-party telephone interfaces and of the Clear-Com AB-100
On-Air Ann
ouncer's Console to Matrix Plus 3 without any modications.

The PSU-101 is the power supply for the IMF-3 interface frame. The one-rack-space unit
may be connected with a second unit for fully redundant operation. It has both an audible
failure alarm and failure relay contacts to activate a remote signal. A single PSU-101 will
power a minimum of two interface frames, depending on the type of interfaces and their
individual power requirements. Additional power supplies may be added in installations
with a large quantity of interfaces, to provide both sucient power and redundancy.
