Introduction

Congratulations on your decision to use a Symetrix model 610 Broadcast Audio Delay. The 610

has been designed to give broadcasters unequaled performance combined with ease of use and

reliability. This manual will guide you through the installation and operation of the 610, and

provide valuable tips on how to interface with other equipment in your studio or control room.
The 610 gives the host or producer of a talk show the power to prevent the broadcast of unwanted

profanities or comments from telephone callers. As the program begins, the 610 gradually and

unobtrusively delays or "stretches out" the program until 7 1/2 seconds of 14kHz bandwidth

stereo audio is stored in memory. When a person on the telephone line says something the host or

producer does not think appropriate for the broadcast, he or she presses the DUMP PROFANITY

button and the memory is cleared, thereby preventing the unwanted audio from reaching the

airwaves. Meanwhile, the host releases the offending caller from the telephone line and proceeds

with the program. After the DUMP PROFANITY button has been pressed, the 610 automatically

begins to stretch (time expand) the program audio again until the full 7 1/2 second delay is

attained.
Several minutes in advance of the end of the talk show, the host or producer presses the EXIT

DELAY button and the 610 begins to time compress the program audio until there is nothing left

in the 610's memory (zero seconds delay). At this point the program is back in "real time" and the

610 automatically removes itself from the signal path.
A unique feature of the 610 is the COUGH button, which allows the host to make impromptu

interruptions in the program for up to 7 1/2 seconds while keeping the audience unaware of the

break. When the COUGH button is pushed, the 610 plays from memory while the button is held

in. As soon as the button is released, the 610 automatically begins to refill the memory. The host

can cough, have a quick drink of water, or make a comment to the producer or engineer without

any perceptible program interruption.
The 610 uses the latest in delta-sigma conversion technology coupled with advanced digital

signal processing (DSP) algorithms. This combination produces a product that meets or exceeds

the highest broadcast standards in terms of low noise, low distortion, and superb signal process-

ing.
The 610's logical, easy to use control panel holds no hidden surprises. The product is easy to

learn and simple to use. In the sections that follow you'll find information on installation, opera-

tion, and specific applications of the 610. We follow this with a troubleshooting guide, warranty

and service information, and detailed specifications.
As with all Symetrix products, the 610 has been designed and built to the highest standards of the

broadcast industry. Our company is committed to excellence in product design, manufacturing,

and service. Please do not hesitate to contact us with your questions or comments.
