The unit comes with its own surfacemount box which provides 1/2" conduit access. The unitwill accept input signal from a 8 Ohm, 25V, 70V or 100Vpaging system and reduce it to a low impedance reducedlevel output.Applications• To expand existing 8 Ohm/25/70/100V pagingsystems without replacing the main amplifier. AV-1094A preamp expander may also be requireddepending on the number of speakers added.• To provide master volume control convenience to allor a portion of a paging zone.Dimensions/Weight• 4.44"H x 2.75"W x 2.88"D(11.28cm H x 6.99cm W x 7.32cm D)• 0.9 lbs.
