Description

AMP2A-10S

2-CHANNEL AUDIO MONITOR

The AMP2A-10S provides self-powered, full-fidelity
stereo audio monitoring in a compact two rack space
cabinet. A front panel switch allows the operator to
select one stereo source for monitoring and output
from up to 10 stereo analog inputs (20 channels).

The AMP2A-10S features two 20-segment LED level
meters showing VU or PPM for accurate level­metering. This unit contains three audiophile-quality
drivers and three power amplifiers; two speakers and
amplifiers 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 unique design provides optimally focused sound
for operators in an ultra near field (1 to 3 ft.) working
environment and offers 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.

Excellent 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 front panel features an innovative LED
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 AMP2A-10S 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.
