The Comtek AP-230 allows a user to listen to pre-recorded cues from a tape player, MP3 player, or similar device during a speech or presentation. It may also be used with all Comtek personal receivers to receive live cues.
The system consists of an IR-230 in-ear induction receiver and an NTC-102 neckloop transductor with two 32" down-lead cords (one with a 1/8" and one with a 3/32" plug).
Using induction technology allows the system to be invisible to the audience, as no wires travel directly to the ear.
