The Alpha Communications®/Norcon patented TTU-1 TalkThru Communicator is a 2-way, hands-free audio system that
provides high-quality personal communication between
people separated by security or isolation barriers. It is the most
widely used system of its type in the U.S., and the world.

How It Works...
The Alpha Communications®/Norcon TTU system permits handsfree, 2-way communication between the booth attendant and the
customer. Vox circuitry facilitates ongoing, clear, 2way conversation at all times - as if the two parties were together
in the same room.
Partition hole 3 to 4 in. dia. (3.50"
recommended) Please specify barrier
thickness when ordering

Today's security and isolation booths and ticket booths are often
the best step you can take to protect your employees. But do
they protect and also help maintain your very important good will?
Not if clerks and customers have to shout and growl and repeat
themselves to be heard or understood.
The TTU-1 Talk Thru Communicator now incorporates circuity to
automatically attenuate the outside channel. If the gooseneck
microphone is not used for a period of 30 seconds, the outside
channel 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.
