The Sennheiser EK 2000 IEM wireless bodypack receiver puts powerful and reliable in-ear monitoring performance in a very compact and tough metal housing. The EK 2000 IEM is designed to deliver dependability — the earphone cable can even double as a second antenna! Its HDX compander provides ultra-clear sound on any stage. You get a Hi Boost function, an onboard limiter, a stereo/focus mode, an adjustable balance control, and a backlit graphic display. It's easy to synchronize settings with transmitters, thanks to the cordless infrared sync function on the EK 2000 IEM.
