Interconnect your 2- and 4-wire intercom systems with this 2/4 Wire Converter from Hollyland. The converter features 3-pin XLR inputs for 2-wire or 4-wire intercom systems such as ALTAIR, ClearCom, Hanson, Syscom, and Datavideo, and it is powered using the intercom system over a 12 to 36V 2-wire connector. Other features include voltage and static protection, electrostatic discharge (ESD) testing to avoid damage, and distance compensation switches that support cable lengths up to 656'. The unit measures 1/4 RU and can be daisy-chained with up to three other units to create an environment for four sets of intercom connections with a 1 RU form factor.
