Overview
The ew IEM G4 Twin is a complete wireless in ear monitoring kit for two performers. One SR IEM G4 transmitter feeds two EK IEM G4 bodypack receivers. Send a different mono mix to each of the transmitter's two inputs, set each receiver to Focus mode, and each performer picks the left or right channel and hears it in both ears. One Twin gives two performers their own independent mono mix, so it suits a duo, a worship leader and a backing vocalist, or a drummer and bass player.
In the box are the SR IEM G4 half rack transmitter, two EK IEM G4 receivers, two pairs of IE 4 earphones, four AA batteries, a rod antenna and a GA 3 rackmount kit. The transmitter accepts two balanced inputs, so you can run one stereo mix for both receivers or, more usefully, two independent mono mixes. Pairing is by infrared, and the system works with Sennheiser Wireless Systems Manager. It is a proven option for churches, bands and venues moving off wedges. FFP supplies Australian legal bands and can advise which one suits your venue.

Forefront Tip
Patch one performer's mix to the left input and the other's to the right, then set both receivers to Focus mode and have each performer select their channel. Anyone who needs a stereo mix should be on their own single system. The IE 4 earphones get you started, but most performers end up on something with a better seal. The Sennheiser IE 100 PRO with foam ear adapters is the usual upgrade and makes a real difference to how loud people run their mix. Mount the transmitter antenna with clear line of sight to the stage, and if you add more IEM systems, keep them on the same band and use the frequency bank so the channels stay compatible.
