User manual ELECTRO-VOICE T18 EDS

[. . . ] The T18 EDS provides a wireless link between your calibrated measurement microphone and audio analyzer. [. . . ] That means you can quickly test multiple locations from the front row to the nosebleed seats in the time it would take to haul long mic cables to just one spot. · Wireless link between test microphone and audio analyzer allows faster, easier measurement of large performance spaces · Optional 48V phantom power supply works with any measurement microphone · Non-companded transmission does not affect audio quality The key feature of the T18 EDS is that it defeats the compander on both the receiver and bodypack transmitter. Wireless mic systems normally use companding (compressing/expanding) to stuff more dynamic range through narrow wireless channels. The T18 EDS receiver includes two detachable 1/4-wave antennas, and can be rack-mounted with optional hardware.
