The EO3 from Nady is a professional wireless in-ear monitoring system that allows you to transmit audio to a performer at distances of up to 300'. The system consists of a compact base station transmitter and a lightweight beltpack receiver. The EO3 system is available in 8 separate preset channels in the 72-76MHz band.

The transmitter offers mic and line level inputs to accept a variety of sound sources. It can transmit to an unlimited number of receivers (extra receivers sold separately) and has an input gain control, plus an automatic level control function. It has an extendable antenna, plus LED indicators for visually monitoring the transmitter's status. It operates via the included 9VDC power supply adapter.
