The Protech Audio Model 589 is a high quality

audio controlled switch coupled with a profes-

sional quality preamplifier. The unit is designed

for applications requiring switch closures to

follow the presence of an audio signal.

Typical applications are public address

systems, broadcast studios, sales presentation

rooms, headphone listening systems, multi-

room audio systems, and recording systems.

The actual application of the amplifiers is

found in buildings such as airports, factories,

courthouses, casinos, convention centers,

libraries, hotels, racetracks, training systems, cor-

porate boardrooms, etc.,.

The unit is capable of functioning in a wide

variety of installations. A typical application

would be the turning on of bypass relays in

paging systems during priority announcement.

Multiple units may be used to design a multi-

level priority system. The switch-selectable re-

mote threshold capability allows this unit to

serve well in systems requiring different thresh-

old levels at different times of the day.

The built-in preamplifier, is switch selectable to

serve as either a microphone preamplifier, or a

line amlifier.

MODELS COVERED

The built-in preamplifier is a very cost effective

feature, eliminating the need for separate micro-

phone or line level preamplifiers.

The Model 589 features two different types of

closures, CMOS and Relay. The relay closures are

configured in two Form C contact arrangements.

The CMOS closures are arranged in two Form A

contacts. The relay closures are capable of switch-

ing high current loads. The CMOS is recom-

mended for lower level audio (microphone level)

switching, since they introduce no switching

noise. Both sets of contacts have an adjustable

threshold, to determine when they activate, as

well as an adjustable drop-out delay, to

determine how quickly the switch opens, after

the incoming audio stops.

The Model 589 is designed to mount in the Model

857B or 858B Card Frame. The unit may be mixed

or matched with other INTEGRA III SYSTEM cards

to create a complete audio system.

The Model 589 Audio Controlled Switch may be

expected to provide years of uninterrupted, quality

service. For additional information, or design as-
