matrix panels, these keys can be programmed either at the panel itself, or from the configuration computer (not shown) that is attached to the Zeus.

IFB828 IFB Power Supply

This unit is the Model 4010’s matrix brother. Since all priority, tally, and interrupt chores and handled by the Zeus™ matrix, the IFB828 acts simply as a power center for the 4030 talent stations. There are eight of these circuits available. The program sources from the audio console are connected directly to the Zeus on the same ports that are used by the IFB828.

SSA324 System-to-System Adapter

The SSA324 changes a two-wire circuit to a four-wire circuit for introduction into the matrix. Each SSA324 is capable of two of these circuits. We have four ports in our scenario.

PS15 Power Supply

Provides operating voltage, with active impedance generator, to the BP325, BP318’s, and the MRT327-K.

SAP612 Source Assign Panel

Since a matrix typically assumes more of the traffic management role than our previous two-wire consoles such as the 803, less outside source assignment is required. Therefore, we can specify the smaller SAP612 for our application to achieve the desired circuit assignment. The SAP612 assigns 12 positions (TW two-wire stations) to one of six conference circuits. As with the larger SAP1626, the SAP612 in our system does two things: it assigns each of the 2 TW channels to 1 of 6 conferences amongst themselves, and it fixes each of these conferences to up to 4-talk/listen keys on the matrix stations.

MRT327-K Modular User Station

The MRT327-K was chosen for the Chyron positions in our medium system for its simplicity. These stations are capable of two-channel operation, one channel at a time.

PAP951 Program Assign Panel and UIO256 GPI

These ancillary devices attach to a special connector on the matrix. No extra ports are required, preserving the maximum size of the matrix. Meaning, more of these units can be added to the system. The PAP951, located in the Audio position, allows the operator to quickly assign programs to IFB circuits. The unit attaches to the matrix on a digital pair, and no actual audio flows through this controller device.

The UIO256 is a 16x16 General Purpose Interface unit. It is included in our intercom for keying a two-way radio in future expansion of the system. If a squelch relay contact closure is available from the radio, the UIO256 can cause a flashing tally to appear at any given matrix keypanel when there is activity on the radio.

Cameras in the Medium Intercom

If the cameras can be set to four-wire intercom operation, they can be tied directly to the matrix. They may be established as any number of conferences. Operating in this manner gains the advantage of camera ISO ability from any matrix station (on the left side in figure 4). Also, the audio levels to and from the cameras can be set internally within the matrix. No extra outside audio amplifiers are necessary. The reason for this is the RTS™ Zeus is a mixer, not just a matrix of physical crosspoints like those we had in the past.
