MODELS COVERED
The 2000-600 Series Audio Distribution Amplifiers
are designed for use in professional audio applica-
tions. Each model is designed to accept an audio
signal in, and send the signal to multiple destina-
tions.
Typical applications are public address announce-
ments that must be fed to different zones or power
amplifiers, program material that must be fed to
different studios, headphone listening systems
where the user can select different program sources,
or audio recording systems where the program
material must be fed to the recorders at the same
time it is being fed to a public address system. The
actual application of the distribution amplifiers is
found in buildings such as airports, factories, court-
houses, casinos, convention centers, libraries, race-
tracks, training systems, and corporate boardrooms,
to mention a few.
The 2000-600 Series Audio Distribution Amplifiers
are designed to incorporate a combination of fea-
tures that will allow the units to deliver maximum
performance and reliability. Each circuit is de-
signed with a minimum of components, to reduce
the possibility of failure, while still maintaing perfor-
mance and feature criteria.

Each one of the 2000-600 Series Audio Distribution
Amplifiers is designed with the same combination
of features. The number of outputs is the only
variable between models.
The gain structure of the 2000-600 DA"s allows the
level of each output to be individually adjusted. The
output level may be adjusted up or down, with
respect to the input level. If a low input level is
present , and more gain is required, the input
section has an additional 15dB of gain. The trimpots
used to adjust the input and output levels are
mounted on the PC board assembly. This feature
allows the system gain settings to be adjusted from
the front of the card frame, using an extender card.
Since the 2000-600 Audio Distribution Amplifiers
are used to connect multiple pieces of audio equip-
ment, and there exists the potential for ground
loops when doing so, the input section and output
sections on each unit are individually isolated using
high quality audio transformers. This feature pro-
vides the maximum in isolation and ground loop
prevention.
These products are designed to provide the user
with high quality audio, for years of uninterrupted
service.
