Professional receivers and transmitters now with a wider switching bandwidth (copy)
Audio specialist Sennheiser is launching new versions of its professional wireless products. TheEM 3732-II twin receiver and the SK 5212-II bodypack transmitter feature a switching bandwidth of up to 184 MHz and have a special mode for more interference-free transmission frequencies. This means that sound engineers can adapt to worldwide transmission conditions more easily and avoid interference from other transmitters - with the same excellent channel separation and strong signal immunity that they are accustomed to from professional Sennheiser systems.
Reliable reception with wider switching bandwidth
The doubled switching bandwidth has not impaired the reliability of the EM 3732-II receiver and its sister models, the EM 3731-II and EM 3732-COM-II. "The receivers are fitted with very high-quality linear amplifiers and auto-tuning filters," explained Astrid Vettin, Product Manager Professional Systems. "This greatly reduces the amount of intermodulation products, ensuring reliable reception even in difficult RF environments."
The flagship in Sennheiser's professional series: the EM 3732-II receiver has a switching bandwidth of up to 184 MHz
More reliable transmission for multichannel applications
In addition to a wider switching bandwidth, another new feature of the SK 5212-II bodypack transmitter is the "Low Intermodulation" mode, which significantly reduces transmitter intermodulation. The problem of transmitter intermodulation occurs whenever several transmitters are used in close proximity, with the unwanted intermodulation products limiting the number of usable channels.
Astrid Vettin: "With the Low Intermodulation mode of theSK 5212-II, the sound engineer can pack around 30 per cent more channels in a given frequency band than before and the spectrum can be used much more efficiently. Alternatively, one can simply benefit from the increased reliability that this mode offers." Of course, the transmitter can also be operated in standard mode at 10 mW - thus extending the operating time - or can transmit at 50 mW in order to increase the range.
Even with this additional function, the transmitter is still as compact as ever and uses just one AA cell - a special asset for broadcasting applications, musicals and live productions, where the size of the transmitter plays a key role. 
The new SK 5212-II bodypack transmitter features a switching bandwidth of up to 184 MHz and a Low Intermodulation mode for even more efficient use of the frequency spectrum
The frequency ranges of the new devices are 470 to 638 MHz (L-band), 614 to 798 MHz (N-band) and 776 to 960 MHz (P-band). The transmitter is also available as a special US version with 614 to 697.9 MHz (US N-band).
