Trilogy’s IEM is a high quality UHF stereo In Ear Monitoring system designed for use in broadcast applications, for use by in-vision talent/presenters that need to listen to programme sound and instructions during programme making.

The base station is DC powered, via a supplied mains adaptor and features a menu driven LCD control panel which can display the levels of both audio channels together, or an average of both along with the operating frequency or user name. LED’s indicate stereo/mono and limiter operation. Input is via 3 pin XLR connectors.

The receiver incorporates volume control, an LCD display showing frequency information, 3.5mm stereo jack socket and LED’s showing power and RF reception. It is supplied with a stereo Micro Bud Earpiece or optional acoustic tube earpiece.

The IEM base station connects to any Trilogy intercom system through a single, balanced audio feed. A simple ‘Push To Talk’ key will enable any panel operator to talk to the talent/presenter. Trilogy IEM receivers are fully compatible with the comprehensive IFB functionality found in Trilogy intercom systems.
