The AMP2-S8DA is a complete exceptionally
high quality audio monitoring system oering
premium quality 8 channel Analog and AES/EBU
digital multi-channel audio monitoring &
conversion as well as professional level
metering in a compact two rackspace cabinet.
This unit contains three audiophile-quality
drivers and three power ampliers; two
speakers and ampliers reproduce midrange
and high frequency information in stereo,
while the third amp/driver combination
handles summed LF information below the
500 Hz crossover point.
The AMP2-S8DA
features eight 53 segment
high-resolution tri-color LED level meters
showing simultaneous VU and PPM for
superior level-metering. The front panel
features an innovative LCD Display of
Phase/Polarity Relationships. Output limiter
circuits are incorporated to protect the
speakers, 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.
This unit is ideally suited for use in space
critical environments such as TV facilities,
studios, VTR bays, mobile production vehicles,
satellite links and indeed, any rackmount
environment where multi-channel audio
monitoring is required. Built and rigorously
tested in the USA, our products are backed by
a strong warranty and a “Satisfaction
Guaranteed” return policy.
