INTRODUCTION

The R175 is a fixed frequency, crystal controlled receiver designed for use in public

address applications. A proprietary Digital Code Squelch* is used in the system

design to eliminate squelching problems caused by interference. The compact size

of the receiver permits mounting the receiver almost anywhere. The audio output is

a balanced XLR type, variable in level, to match any type of sound system.

The digital code system provides much more reliable control over the receiver audio

output than a conventional squelch can provide. The matching transmitter generates

a 9-bit code at turn on, and another code at turn off, to open and close the audio

output on the receiver. The squelch on the receiver cannot be opened by anything

other than the specific code it is programmed to receive. This type of squelch

system is even more important when the receiver is connected into an automatic

mixing system.

The R175 circuitry utilizes the latest surface mount technology, with significant

oscillator shielding. Up to four systems can be operated simultaneously in close

proximity in the 169 to 172 MHz band without intermodulation, crosstalk or squelch

problems. The housing is a durable aluminum extrusion with rugged connectors for

lasting reliability.
