The Model 985DTV Component Video Distribution Amp provides dazzling video quality and digital audio to multiple monitors! Use either optical (TosLink connector) or coax (RCA jack). The self-terminating bus allows multiple AA-985DTV modules to be chained together. An optical TosLink(tm) feed insures that any digital audio source may be used with our latest A/V distribution system. Each AA-985DTV distributes signal to four monitors. Since the unit is invisible in the signal path, modules may be connected together to allow multiple monitors to show the same source signal. The clearly labeled connections and self-terminating bus make installation a snap.
