General Description
The new EM 3700 Series combines highest operational reliability, best sound quality and great convenience and comfort for the user. The wide switching bandwidth of 90 MHz and many connection options make these receivers the most flexible tools in the market. They feature a number of innovative functions, such as a digital audio output, high-contrast display and extraordinarily intuitive operation via an icon-based menu. Via their Ethernet connector, the receivers can easily be integrated into any network to be remote-controlled and monitored via the Sennheiser Wireless Systems Manager (WSM) software. The sync function ensures a quick system set-up, enabling SK 5212, SKM 5200 and SKP 3000 transmitters to be synchronised with the receivers via an infrared interface. The receivers are fitted with an AES3/EBU digital audio interface for direct connection to digital mixing consoles.

CONSUMER ALERT
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at
