Meyer Sound DS-2P User manual

this unit is as simple as
plugging-in a power source
and an audio signal source.
The amplifier unit
is equipped with TruPower™
Limiter technology, which
maximizes speaker protection
reliability and component life.
This breakthrough in speaker
control also results in higher
SPL at all frequencies, and
increased available headroom.
Long term power compression,
typically 3-6 dB in conventional
systems, is less than 1 dB.
Maximum SPL capability
remains constant even during
operation at high levels for
extended periods.
DS-2P performance can be
supervised using the Remote
Monitoring System™(RMS).
This enables users at a
The DS-2P is a self-powered,
arrayable mid-bass loud-
speaker designed to
supplement the MSL-4 unit in
the 40-160 Hz range. It can
also be used with other, non-
powered units such as the
MSL-3A and MSL-10A. It
delivers high audio power with
extremely low distortion.
The DS-2P uses two 15-inch
cone drivers in a folded horn
enclosure. These horns have a
hyperbolic flare that give the
unit maximum energy transfer
with minimum frequency
response ripple.
The DS-2P has the
Intelligent ACTM system, which
performs automatic voltage
selection, EMI filtering, soft
current turn-on, and surge
suppression. Installation of
FEATURES
computer terminal to monitor
such parameters as limiting
activity, power output, voltage,
temperature, fan speed, and
driver status.
The built-in power amplifier
is designed for maximum
efficiency and reliability.
Servicing in the field is
facilitated by the modular
design of the DS-2P; the
entire power/amplifier module
can be accessed and replaced,
if necessary.
