SECTION I
INTRODUCTION
1-1 GENERAL
The new solid-state Audimax
®
III, Model 444, like its companion piece, Volumax
TM
, is a tool to
help the broadcaster achieve maximum program power within appropriate modulation limits.
Incorporating all of the features of its famous predecessor, the Audimax III also provides
additional gain and versatility. Designed for use wherever high quality automatic gain riding is
required, Audimax III offers a unique method of audio control for AM, FM, and TV broadcasting,
recording, motion pictures and public address use.
Audimax III is the latest development in the unique Audimax system of audio control developed
by CBS Laboratories. Applicable to all audio media, the Audimax is totally different in concept
from ordinary compressors, limiters or AGCs. The Audimax acts like a highly capable studio
technician, but without many human limitations. Valuable in the studio, the Audimax is often
more reliable outside, away from controlled studio conditions. The ability of the Audimax to act
instantly and control audio levels intelligently frees engineers to cope with the may other
problems of remote pick-ups.
The new solid-state Audimax III offers the ultimate in automated gain control combined with the
extreme reliability of solid-state circuitry. The exclusive GAIN PLATFORM principle permits gain
to remain on a stable plateau over a wide range of input levels rather than continuously allowing
it to rise and fall with consequent distortion, thumping and pumping, and audio "holes". The
unique GATED GAIN STABILIZER acts to bridge through program lapses and thus eliminates
“swish-up” of background noise. A special RETURN-TO-ZERO function returns gain to normal
during standby conditions.
1-2 WARRANTY
A warranty, with a return post card is included with your Audimax III. Fill out the post card and
return it to CBS Laboratories as soon as possible to validate your warranty.
