Brief description
With the EM 3532-U twin receiver, Sennheiser offers the professional user a high-quality state-of-
the-art RF receiver with a high level of operational reliability and ease of use. The EM 3532-U
receiver together with the suitable hand-held and pocket transmitters permits wireless transmission
with studio-quality sound. Due to further optimised PLL and microprocessor technology and the
Sennheiser patented HiDyn plusTM noise reduction system, these transmission systems surpass the
signal-to-noise ratio and dynamic range of modern CD productions. The true diversity technology
of the EM 3532-U receiver ensures interference-free transmission and minimises dropouts in the
RF link.
Especially for small television studios and theatres, the simultaneous use of several Sennheiser
3000 series receivers ­ such as the EM 3532-U ­ is an economical alternative to technically more
sophisticated and therefore more expensive multi-channel systems of the 5000 series.
