Old Lyme, CT (June 19, 2008)--Sennheiser has begun to ship its EM 3732 twin receiver with 90 MHz switching bandwidth. The new flagship of Sennheiser's 3000 Series, the EM 3732 reportedly offers automatic scanning functionality, choice of five frequency ranges, transmitter synchronization via infrared interface, and flexible analog and digital connection options.
The EM 3732 receiver features six user-selectable fixed frequency banks and one user bank with up to 60 channels that can be programmed in increments of 5 kHz. The EM 3732 automatically searches for free frequencies within a frequency bank.
An integrated antenna splitter allows up to eight EM 3732 twin receivers to be daisy-chained. The EM 3732 is targeted for large multichannel applications, not just because of its wide switching bandwidth and tunable channels, but also because of its infrared interface, which programs SKM 5200, SK 5212 and SKP 3000 transmitters with the receiver data via a Hot Key.
The receiver's front-panel layout is clearly laid out and its LED display offers high contrast and intensity. The interface guides users through intuitive operating menus, featuring easily remembered icons, which are navigated using a jog dial. Frequently used menu items can be accessed directly via convenient Hot Key shortcuts. Both receivers can be monitored via headphones individually or simultaneously.
The receiver system can be remote-controlled and monitored using the provided Wireless Systems Manager software. The PC is simply connected to the Ethernet socket of the EM 3732.
Output level can be set in increments of 1 dB and is available at a transformer-balanced XLR-3 analog output as well as an AES3/EBU audio output for direct connection with digital mixing consoles. Digital synchronization of the 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz/24-bit sample rate can be generated internally or accepted from the digital audio mixer via a BNC connector. The audio quality is further maintained through the use of a DSP-based HiDyn plus expander rather than analog circuitry.
A range of antenna accessories is available for the EM 3732 twin receiver. The AB 3700 broadband antenna amplifier is designed for a frequency range of 470-866 MHz and amplifies the received signal by 5 to 15 dB. The antenna booster is fitted with four multi-color LEDs that indicate amplification in 5 dB increments, permitting the sound engineer or RF engineer to read the respective setting even from a distance. Unlike conventional antenna amplifiers, the AB 3700 will open a second, low-attenuation (-6 dB) signal path in case of power cuts. Further, two active receiver antennas are available--the directional AD 3700 and the omni-directional A 3700.
