audio to the HDX system

RealPresence Series
Unfortunately, the RealPresence series uses a proprietary audio connector and cable. This product is
not directly compatible with the Shure Microflex Wireless system. To use the Microflex Wireless system
with a RealPresence Series system, you must first connect Microflex Wireless to a SoundStructure C-
Series processor as described above and then send audio over the digital microphone connector to the
RealPresence.
