The AMP1-SDA provides self-powered,
full-delity stereo audio monitoring of 2 chan-
nels from Analog, AES/EBU Digital and SDI
sources in the smallest rack space possible.
This unit contains four high performance
transducers driven by three power ampliers:
one amplier/driver combination handles
midrange and high frequency information in
stereo, while the second handles summed low
frequency information below the 500 Hz
crossover point.
The AMP1-SDA features two 26 segment LED
level meters showing simultaneous VU & PPM
for accurate level-metering. The front panel
features an innovative LED Display of
Phase/Polarity Relationships. Output limiter
circuits are incorporated to protect the speak-
ers, and extensive magnetic shielding allows
placement immediately adjacent to video
monitors with no color impurities.
The unique design provides optimally focused
sound for operators in an Ultra Near Field
(1 to 3 ft.) working environment and oers
performance comparable to that of many
separate monitor pairs, yet does so without
the installation hassles, awkward speaker
placements and “added-on” look. This
provides for a higher SPL for the operator
while reducing overall ambient sound and
adjacent bay crosstalk. Extended HF response
reveals potential problems with audio whine
or hiss and electronic rather than acoustic
cancellation of bass frequencies provides
positive audible detection of out-of-phase
(reversed polarity) audio feeds. A headphone
jack is provided on the front panel, usage
automatically mutes the speakers.
The AMP1-SDA is ideally suited for use in
VTR bays, mobile production vehicles,
teleconferencing installations, multimedia
systems, satellite link and cable TV facilities,
and on-air radio studios. Built and rigorously
tested in the USA, the AMP1-SDA is backed
by a strong warranty and a “Satisfaction
Guaranteed” return policy.
