AES: Sennheiser EM 3732

Sennheiser’s EM 3732 twin receiver with 90MHz switching bandwidth offers automatic scanning functionality, a choice of five frequency ranges, transmitter synchronization via infrared interface, flexible analog and digital connection options, and high-quality audio.

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 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 dBm and is available at a transformer-balanced XLR-3 analog output and an AES3/EBU audio output. Digital synchronization of the 44.1kHz, 48kHz, 88.2kHz or 96kHz/24-bit sample rate can be generated internally or accepted from the digital audio mixer via a BNC connector. The unit makes use of a DSP-based HiDyn and expander rather than analog circuitry.

The EM 3732 is complemented by two variations: the EM 3731 single receiver and the EM 3732 COM twin receiver, a special command version with a second XLR-3 audio output for talkback purposes. All models will be available late fall 2007.
