Sennheiser EK-IEM G4 (A) (516-558 MHz)

Expand your EW-IEM system with a separate EW-IEM EK. Multiple receivers on one transmitter can obviously be very useful when talking about in-ear monitoring. Not only can you always use an extra bodypack as a backup in case something goes wrong, but of course it is also possible to connect multiple receivers to one transmitter.

In-ear monitoring can be quite an expensive proposition if you want to do it right. Never mind that of course every transmitter has to receive a signal and the AUX outputs on many mixers are limited. Here it could possibly be smart to put multiple receivers on one transmitter. With one EW-IEM transmitter, you can send either one stereo mix or two mono mixes to as many receivers as you want. A very practical solution in a situation where you can only do one or two AUX mixes, or a budget-friendly solution for the band.
