The system comes complete with a 72-port rear connector panel, full internal circuitry for interboard communications and signal processing, the system configuration card, and multi-pin connectors for the matrix cards. The frame can contain any desired combination of the following eight-port matrix cards: MTX-A8 analogtransmission cards or MTX-D8 digital-transmission cards. The matrix frame connects with all Matrix Plus® intercom stations, and either directly or through interfaces can connect with telephone lines, two-way radios, wired and wireless party-line intercom systems, cameras, IFB systems, and control systems of various kinds. With the Compact 72, virtually any type of intercommunications system can be created. Compact 72 Rear View D D S P™ I N T E R N A L C O M M U N I C AT I O N S Distributed digital signal processing (DDSP) is the key to the incredibly fast and reliable communications of Matrix Plus 3, also yielding compact size and high system capacity. Each matrix card processes the audio signals from its eight send and receive ports, and communicates directly with the other boards, digitally and in real time. Precision 8-layer surface-mount boards contain custom DSP chips and processors. Boards are “hot-patchable” and “self-initializing”, allowing system expansion and maintenance during ongoing operations. VA R I A B L E L I S T E N L E V E L S Every Matrix Plus intercom station allows the operator to easily adjust the listen level of any voice or program audio signal being monitored at the station. In addition, software can control the input and output levels of every port. Every station can create its own unique “mix”, without affecting overall system audio levels. M U LT I P L E O N - B OA R D C O N F I G U R AT I O N S The Matrix Plus system stores up to four configurations – full system setups – on-board for rapid recall and changeover of the system. These configurations may be activated either from the frame itself, from selected intercom stations, or from a computer linked to the frame.

Changeover between power supplies is completely transparent to the system, for fail-safe operation. The unit has both an audible failure alarm and failure relay contacts to activate a remote signal. An over-temperature sensor is connected to both an audible alarm and a warning LED, allowing the system operator to diagnose and correct any power anomalies while the system remains operational. P OW E R F U L , I N T U I T I V E P RO G R A M M I N G S O F T WA R E Powerful, easy-to-use software, operating under Windows 95/98/NT, is used to create “configurations” encompassing all operating parameters of the complete system. Customize the matrix to any requirement with easy-to-grasp menus and tables and context-sensitive help screens. Enable or inhibit features at any station, create groups and point-to-point connections, add passwords and priorities, set crosspoint levels, and more. Create 5-character alpha-numeric labels, assignable to any port/station. C O N N E C T I N G TO T H E C O M PA C T 7 2 The connector panel on the rear of the Compact 72 links the frame to stations and interfaces. It contains a total of 72 RJ-45 connectors, arranged in groups of eight, corresponding to the channels on the matrix cards. Each RJ-45 connector provides input and output paths for one channel of audio, plus data paths. SIMPLE WIRING The Compact 72 frame provides standard RJ-45 telephone-type connectors for quick setup, simple changes, and troubleshooting. Panels are clearly marked to ensure proper connections. When MTX-A8 analog-transmission cards are installed in the Compact 72, frame-to-station wiring uses four-pair CAT-3 cable. The four-pair connection routes talk and listen audio signals, and provides data input and output paths. With MTX-D8 digital-transmission cards installed, connection between the frame and stations is accomplished with either single-twisted-pair or coaxial cable. Audio and data travel along the same wire and remain as digital signals until decoded at the station. Matrix Plus digital intercom stations may be ordered from the factory in either an analog- or digital-transmission format, with the proper modules and connectors installed.
