LAS VEGAS, USA (AVING Special Report on 'NAB Show 2010') -- <Visual News> Sennheiser launched new versions of its professional wireless products at NAB Show 2010.
The EM 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 transmitter 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 enhances the flexibility and versatility 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 Robb Blumenreder, channel manager of professional systems at Sennheiser's U.S. headquarters. "This greatly reduces the amount of intermodulation products, ensuring reliable reception even in difficult RF environments."
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.
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.
Available frequencies for the SK 5212-II and EM 3732-II are 470-638 (L-band) and 614-697.9 (N-band).
