Sennheiser EM 550 G2 A Dual Receiver 518-554MHz

Only available as part of a complete wireless system.

The EM 550 G2 twin receiver consists of two complete true diversity receivers in a single 19” rack housing. The two receivers can be operated independently from each other. The EM 550 G2 has an integrated antenna splitter, enabling you to daisy-chain up to eight twin receivers. The EM 550 G2 can be combined with transmitters of the ew 500 G2 series to make high-quality state-of-the-art RF transmission systems for professional applications. The transmitters and the twin receiver have a high level of operational reliability and are extremely user-friendly.
