The Basic Voice Communication System for
High-Security and Isolation Booth Situations
Today's security and isolation 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

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 cir-

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, annoy-
