Radio Design Labs' FP-AVDA4 is the perfect 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. The FP-AVDA4 has a single 75 O input phono jack for the video signal and two phono jacks for the left and right audio inputs. Four source-terminated, 75 O 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.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.
