This is for a single UVive U4T In-Ear Monitor Wireless System Transmitter Only. Below is the description for a complete system. This additional transmitter allows you to create a separate mix for one or more of your band members. Let's say you already have a transmitter and 4 receivers and now the singer wants her own mix. This transmitter is the way to go.

The UVive U4 In-Ear Monitor Wireless System Set provides clear sound for stage performers just where they need it, which helps boost your overall performance quality. As a portable wireless system, you don't need to set up much. Just plug-and-play to quickly build your monitoring system. This is an affordable solution that doesn't take up much space and is quickly rechargeable via USB

Batteries and charging
U4 includes a USB charging cable that connects to any USB charger adapter or other USB charging devices.

Pair transmitter and receiver
U4 has six channels. Use the channel switch button to switch the channel. Set the receiver channel to the same as the transmitter and you're good to go. The blue Led signal on the receiver will stay be on when the connection is successful.

Single transmitter and multiple receivers
If you want to add more receivers, just set the receivers to the same channel as the transmitter. There's no hard limit to how many receivers can connect to one transmitter, but you'll all be sharing the same mono mix.

Ear-buds not included.
