The EM 550 G2 twin receiver

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 extremly user-friendly. The excellent transmission reliability is based on the use of

yfurther optimized PLL synthesizer and microprocessor technology,

ythe HDX noise reduction system,

ythe pilot tone squelch control,

ythe true diversity technology (rack-mount receiver only),

yand the scan function for scanning the channel banks for free channels.
