| Earsets

The popular RTS earsets are precisely designed for inconspicuous listening while on camera� Used by nearly all major
television networks and stations, we have surpassed industry standards� The extremely efficient miniature driver
element requires only nominal operating power and enables the announcer to hear program cues while working with
a live microphone� The units are also suitable for many other applications such as live theater script prompting�

Typical Set-Up

To provide optimum versatility, the announcer’s earset is made up of interchangeable components that simply snap
together� Users can construct a version of the announcer’s earset that best suits their particular needs� Some popular
combinations are available as a standard configuration; these are listed below�
