Introduction
The Venture-Express portable transmitter results from years of
surveying audiologists, sound contractors, consultants and
end users. It is designed to provide every feature and
function with the highest possible audio/RF performance and
reliable operation while remaining affordable and easy to use.
The Venture-Express has audio inputs for both microphone
and line (i.e. tape or CD player). The two sources can also be
mixed. An audio processor shapes the input audio dynamics
and frequency response to produce a signal with maximum
intelligibility and minimal operator adjustment.
The RF section is crystal-controlled for stability. Its digital
frequency-synthesizer circuitry sets the transmitter to 19 of
the FCC-approved Assistive Listening Band’s channels. Six
memory channels can recall frequent-use channels.

Audio Processing
To make transmitted sound intelligible to the hearing impaired,
making it louder is not enough. The needs of the hearing
impaired differ greatly from those with normal hearing. The
most common impairments are reduced sensitivity and dynamic

range, and loss of high frequencies.
The Venture-Express uses a system of program-dependent
AGC with a proprietary frequency-shaping system to control
dynamics and maximize voice intelligibility. This results in a
clear, loud sound, and eliminates the need to constantly raise
and lower receiver volume.

Controls
Power: Turns on/off the power to the V enture-Express
transmitter
Channel Select: Allow the user to scroll up or down through
the 19 preprogrammed channels
Memory Recall Buttons: May be programmed to any of the
19 channels for instant recall
Display: LCD display shows the channel the V enture-Express
is currently using. If tuned manually , the channel will be
prefixed by a C (example: C-07). If tuned using a memorized
channel, the channel will be prefixed by the memory-button
number (example: 4-07).
Input Selector: Allows the user to broadcast the audio input
from a microphone, a line source or a mix of both
Line Input Jack: A standard 1/8-inch/3.5mm jack for an
outside audio source (i.e. tape or CD player)
Mic Mute Switch: Allows the user to mute the mic audio input,
not the auxiliary audio input
Mic Input Jack: A mini XLR-type professional connector with
a locking action to prevent the mic plug from being
