Xvive Audio U4 In-Ear Monitor 2.4 GHz Wireless System

$ 229.00

The U4 In-Ear Monitor 2.4 GHz Wireless System from Xvive includes a wireless plug-on transmitter and a wireless bodypack receiver. It can be used to monitor your audio performance with freedom from wires for stage, theater, and rehearsal applications. The U4 system features six selectable channels for creating up to 6 individual discrete mixes with an operation range of about 90'. Each component is housed in a durable metal chassis for dependability. The plug-on transmitter offers an XLR input for line-level signals, and the bodypack receiver, a 3.5mm TRS mini headphone jack. Both the transmitter and receiver are powered by internal lithium-ion batteries that last up to 5 hours.

Additionally, you can use one transmitter to send the signal to as many receivers as needed simultaneously on stage. A dual micro-B USB cable, 1/4" adapter, and a carrying bag are also included.

  • Easy to carry, easy to set up. Plug in and turn on the power to build your wireless in-ear monitor system
  • Line mode allows you to use the system with mixers or other professional audio devices that send line-level signals
  • Use AUX mode when connecting consumer audio devices such as portable audio players or computers
  • Provides smooth frequency response with any headphones
  • Use a single transmitter to send the signal to multiple receivers creating a monitoring system for the entire band. You can send the signal from one transmitter to as many receivers as needed simultaneously. Set the receivers to the same channel as the transmitter.
