Sennheiser EK 2000 IEM Bodypack Receiver

The EK 2000 IEM is the bodypack receiver for Sennheiser's 2000-series in-ear monitoring system. Adaptive diversity is the point: rather than switching between two antennas it combines them, which is what keeps a performer's mix from stuttering as they cross a stage full of RF shadows.

It runs 25 Hz to 15 kHz with better than 90 dB(A) signal to noise, gives 4 to 6 hours on a set of batteries, and measures 82 x 64 x 24 mm at 200 g. IE 4 earphones are in the box. It is a tuned product, so order the frequency variant that matches your transmitter and your region.
