MODELS COVERED

The Models 546B (1KHz), and 562B (25Hz) Au-

dio Oscillator cards are designed for use in

professional applications. Typical applications

are multi-zone public address systems, emer-

gency communications systems, training sys-

tems, paging systems, and intercom systems.

The Model 546B is designed to provide a stable, low

distortion 1KHz reference signal for aligning systems,

or to provide audible signals or alarms.

The Model 562B is designed to provide a stable, low-

distortion signal for audio detection or supervision

sytems (See Model 685 Tone Supervisor Card). This

low frequency tone is usually not audible in sound

systems, but may be readily detected by the supervi-

sory card. This type of circuit is quite often found

in systems where crowd control, or emergency

communications are system requirements. The de-

tector circuit monitors the system circuits, and auto-

matically signals the failure of any component in the

system. This facilitates proper maintenance of the

audio system.

Both cards are designed to provide an adjustable -40

to 0dB signal level. The frequency is fixed, via circuit

design.

Both cards feature Bridge-T circuitry, in order to

provide extremely low distortion. The typical distortion

measurement is less than 0.01%. The low distortion

and constant output level are characteristic of this type

of circuit, and makes the oscillator cards ideal for use

as a reference signal when testing audio systems.

There are a number of INTEGRA III SYSTEM cards

available to help mix the audio signals into the audio

system. In the case of the 25HZ signal being used in

conjunction with the Model 685 Tone Supervisor Card,

mixing the signal into the system at the earliest pos-

sible point, will allow the supervisor card to monitor

more equipment.

As with all INTEGRA III SYSTEM cards, both the

Model 546B and 562B Oscillators Cards are designed

to mount in either the Model 857B, or Model 858B

Card Frame Packages. The oscillator cards may be

mixed and matched with other system cards, within

the same card frame, without fear of system degrada-

tion.
