The AllFrame Multi-Modular I/O System from Aviom is an example of how Category 5e twisted-pair copper or fiber-optic cabling can make audio transmission more efficien than it traditionally has been. Environments such as conference centers, schools, performance theaters and houses of worship may be able to take the most advantage of these efficiencies. These environments are permanent installations and as such, the use of a system like AllFrame Multi-Modular I/O eliminates multiple labor-intensive stages of establishing a signal chain, Aviom explains.

Because the system requires just a single Category 5e or fiber-optic connection plus direct-current (DC) power, which can be supplied through the Cat 5e via Power over Ethernet, it eliminates any need for soldering, terminating and testing many analog connections. It also eliminates the need for conduit installation and separate cable pulls for each audio signal. Consequently, setup time for an audio system is significantly reduced, Aviom says.

The system brings Aviom's Pro64 audio network to the wallbox, stage box or floor pocket. The F6 Modular I/O Frame, shown at the bottom of this page, is the system's centerpiece. It has six configurable I/O card slots and integrated Cat 5e and fiber-optic connectivity. Its mounting options include on-wall or in-wall using a standard NEMA Type 1 enclosure, or rack-mounting. The connectors can face front or rear.

Every AllFrame device supports Category 5e runs up to 400 feet between devices with no loss of fidelity, the company says. With fiber, cable runs can extend beyond a kilometer on multimode and longer on singlemode.

Product research and development manager Ray Legnini explains, "By digitizing the audio input signal at the initial connection point, the AllFrame Multi-Modular I/O System keeps analog cabling to a minimum, reducing system complexity and labor costs while delivering improved performance and flexibility."
