Essential Info

The FP-AVDA4 is the ideal choice in applications where consumer format audio and video signals need to be distributed simultaneously. Audio and video inputs and outputs are made on the top panel phono jacks. Power connections are made using either the full-size barrier block terminals or a dc power jack located in one end panel. A second dc power jack is provided on the other end panel for connecting additional Flat-Pak modules.

The FP-AVDA4 has a single 75 Ohm input phono jack for the video signal and two phono jacks for the left and right audio inputs. Four source-terminated, 75 Ohm video outputs are provided on the video output phono jacks. Four stereo audio outputs are provided on phono jack pairs located adjacent to the corresponding video output. Unused outputs need not be terminated. Audio and video outputs are at unity gain.

The FP-AVDA4’s low profile and compact size permit mounting in confined spaces and in various locations in equipment racks. The location of the input/output jacks permits high-density mounting against flat surfaces while maintaining accessibility to the connectors. Installations requiring multiple distribution amplifiers are ideally designed using FP-AVDA4s affixed to rack sides, or by mounting them to either the
front or rear rack rails using the RDL FP-RRA.

Wherever wide-band video and audio need to be distributed economically with professional quality, reliability, compactness and unsurpassed versatility, the FP-AVDA4 is the ideal choice. Use the FP-AVDA4 individually, or combine it with other RDL products as part of a complete audio/video system.

This item requires a 24V power supply such as the PS-24AS or PS-24K for operation.
