Introduction

Congratulations on purchasing the Venture-Base
Assistive Listening Transmitter. The Venture-Base
is the heart of the Gentner Assistive Listening
System. As the most advanced device of its type,
its design and manufacture result from research
with audiologists, sound contractors, consultants
and end users. It is designed to provide the highest
possible audio and RF performance. The Venture­Base is reliable, easy to use and provides quality
performance.

The Venture-Base has audio inputs for audio
sources, ranging from microphone to loudspeaker
(balanced and unbalanced). It contains a series of
audio processors to shape the input dynamics and
frequency response. This produces clear sound for
the hearing impaired, with minimal adjustment.

The RF section is crystal-controlled for long-term
stability, and uses digital frequency-synthesizer
circuitry, allowing the transmitter to be instantly set
to 19 FCC-approved ALS channels.

If you need additional information on how to install,
set up or operate your Venture-Base, please contact
us at Gentner Communications at the location noted
below. We welcome and encourage your comments
so we can continue to improve our products and
better serve your communication needs.
