Norcon's patent pending TTU-1 Talk-Thru Communicator is a 2-way, hands-free audio system that provides high-quality personal communication between people separated by security or isolation barriers.

HOW IT WORKS...

The Norcon TTU system permits hands-free, 2-way communication between the booth attendant and the customer. Vox circuitry facilitates ongoing, clear, 2-way conversation at all times - as if the two parties were together in the same room. The TTU-1 Talk-Thru Communicator now incorporates circuitry to automatically attenuate the outside channel. If the gooseneck microphone is not used for a period of 30 seconds, the outside channel volume will be reduced approximately 70%. Normal operation is restored as soon as the attendant speaks into the gooseneck microphone. The automatic volume attenuation circuit prevents outside noise from bothering the attendant. The TTU-1 provides clear communication even in environments with high ambient noise by shaping the sound for maximum intelligibility. Its compression circuitry decreases loud, annoying sounds.

HOW TO INSTALL...

Installation of the TTU-1 is a very simple, one-person operation. All that's needed is a 3- to 4-in. cutout in the barrier. Four fasteners and two rubber gaskets for mounting are supplied. Specify barrier thickness when ordering. The front face and housing are easily mounted on opposite sides of the barrier using the fasteners. The rubber gaskets prevent slippage and protect the barrier surface. The electronic section is then inserted into the housing and fastened in place. Note choice of continuous-duty, 117-Volt AC power supply stepped down to 12 Volts, or rechargeable nickel cadmium battery operation.
