Sennheiser EK IEM G4 Wireless In-Ear Monitor Bodypack Receiver, A Band

The expansion pack for a G4 in-ear rig: one more EK IEM G4 stereo bodypack receiver with IE 4 earbuds, so another musician joins an existing transmitter's mix — the cheapest way a band grows its IEM system, since one SR transmitter feeds as many packs as you like on the same mix. Infrared sync copies the settings over in a second.

A band, 516–558 MHz; match it to your transmitter's range.
