RC-216 Receive-A-Cue

Live Presentations • One-way Observation Interview Rooms • Law Enforcement

The RC-216 Receive-A-Cue system offers discrete, one-way in-ear cueing. The IR-230D induction receiver and NTC-102 neckloop eliminate the need for visible wires going directly to the ear. With an adjustable volume control and low residual noise, this discrete earpiece is loud enough for even the most demanding environments.

The dual function M-216 transmitter can be used with the lapel microphone for live cueing or with the AUX input for transmitting audio from a line level or headphone level audio source. The listener used the PR-216 receiver and NTC-102 neckloop, which can be concealed underneath clothing. The NTC-102 neckloop then re-transmits voice and/or audio directly to the IR-230D induction earpiece receiver via a magnetic induction re-transmission.

The Option 1 microphone mute switch on the transmitter allows the user to mute the microphone so a third party can be addressed privately without distracting the person receiving cues. Also, the AUX input on the transmitter allows for prerecorded material to be played back from another sound source such as a digital audio player, laptop computer, or even an audio feed from a mixing board. When using the mic input and the AUX input simultaneously, the AUX input will automatically lower its level to prioritize the signal from the mic input.
