TalkPerfect TP-DX-N Duplex Intercom

The Ampetronic TalkPerfect TP-DX-N duplex intercom system is the control unit for a two-way voice enhancement system, with an integral Hearing Loop driver. Based on proven, reliable and patented technology, the full duplex system amplifies speech for both customer and staff whist minimising background noise and actively reducing acoustic feedback.

The TalkPerfect TP-DX-N system not only comprises a full duplex intercom system, reinforcing communications from staff to customer and customer to staff with high quality amplified sound, but is also simple to install, does not require an external computer of software to set up, and once installed it is designed to function without further intervention.

The TalkPerfect TP-DX-N contains signal processing for system stability and clarity of speech and is shipped pre-set, directly for use with minimum set up adjustment.

The Hearing Loop (or Audio Induction Loop System [AFILS]) driver will allow hearing assistance to be provided to customers as part of the installation when connected to suitable installed loop wiring.
