Sennheiser´s professional receivers and transmitters now with a wider switching bandwidth
Audio specialist Sennheiser is launching new versions of its professional wireless products. The new EM 3732-II twin receiver and the equally new SK 5212-II bodypack transmitter feature switching bandwidths that are twice as wide and five times as wide respectively and have a special mode for more interference-free transmission frequencies, thus guaranteeing even more reliable and more flexible wireless transmission for the most demanding multichannel applications.
A switching bandwidth of up to 184 MHz is now available to sound engineers to enable them to adapt to worldwide transmission conditions and to avoid interference from other transmitters - with the same excellent channel separation and strong signal immunity that they are accustomed to from professional Sennheiser systems. "The receivers are fitted with very high-quality amplifiers," explained Astrid Vettin, Product Manager Professional Systems. "Their high IIP3 value - a quality criterion for intermodulation resistance - ensures that the level of intermodulation products is greatly reduced. This means that reliable reception is possible 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
The EM 3732-II twin receiver is also available as a version with a command function (EM 3732 COM-II) and as a single receiver (EM 3731-II). All receivers offer excellent audio quality and user-friendly operation. A clearly legible OLED display, intuitive menu guidance, a frequency scanning function and the ability to programme the respective transmitters via an IR interface make the sound engineer's job much easier. A digital AES3/EBU output allows the receivers to be connected directly to digital mixing consoles, while an ethernet socket enables them to be integrated into networks for remote monitoring and control via a PC or Mac.
More reliable transmission for multichannel applications
In addition to a wider switching bandwidth, another new feature of theSK 5212-II bodypack transmitter is the "Low Intermodulation" mode. In this mode, about 30% more channels than was previously the case can be accommodated within a given frequency window at a transmission power of 10 mW.
Normally, the number of usable channels is limited by so-called transmitter intermodulation, in which the useful signal of the transmitter becomes mixed with signals originating from other transmitters or sources of interference that are picked up by the antenna. The result is a large number of undesirable interference products that are transmitted together with the useful signal. The problem of transmitter intermodulation occurs whenever several transmitters are used in close proximity, for example on stage or in broadcasting, when several presenters and guests are involved.
Astrid Vettin: "The Low Intermodulation mode of the SK 5212-II now makes it possible to significantly reduce transmitter intermodulation. As a result, the channels can be packed more closely together 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," explained Astrid Vettin. "For broadcasting applications, musicals and live productions, where the size of the transmitter plays a key role, the SK 5212-II is the preferred choice worldwide."
The new SK 5212-II bodypack transmitter features a switching bandwidth of up to 184 MHz and a Low Intermodulation mode for even more reliable and more efficient wireless transmission
The frequency ranges of the new devices are 470 - 638 MHz (L range), 614 - 798 MHz (N range) and 776 - 960 MHz (P range). The transmitter is also available as a special US version with 614 - 697.9 MHz (N US range).
The SK 5212-II bodypack transmitter and the EM 3732-II twin receiver with its EM 3732 COM-II and EM 3731-II versions are available now.
