A laser-trimmed differential
input stage affords superior
common-mode rejection to
allow signal runs through a
simple twisted pair cable.
Rear panel LEDs indicate AC
power and driver protection
limiting. The DS-4P’s integral
power supply suppresses high
voltage transients and
incorporates the Intelligent
ACTM system. This automates
voltage selection, allowing
worldwide operation, and
additionally provides EMI
filtering, soft current turn-on,
and surge suppression.
Installation of this unit is
as simple as providing
power and an audio signal
source. Servicing in the
field is facilitated by the
modular design; the entire
power amplifier module
can be accessed and
replaced, if necessary.
The self-powered DS-4P is
an arrayable mid-bass
loudspeaker system that
provides high power sound
reinforcement with extremely
low distortion. It was
developed to supplement the
70-200Hz band in full-range
systems, affording additional
mid-bass headroom. The
DS-4P is most effective when
used in multiples within an
array, and easily can be
incorporated into
conventionally powered or
self-powered systems. The
DS-4P uses two 12-inch cone
drivers in a true horn
enclosure. The horn’s flare
provides maximum energy
transfer in the mid-bands
with minimum frequency
response ripple.
Like all Meyer self-powered
loudspeaker systems, the
DS-4P exhibits superior
performance across virtually
all parameters. Because the
amplifier and control
electronics are optimized for
the drivers, the system is
able to produce more power
with a flatter response and
lower distortion. The self-
powered concept simplifies
installation, and eliminates
amplifier racks and external
drive processing.
The DS-4P incorporates a
two-channel Class AB/H power
amplifier, Meyer Sound’s
proprietary phase-corrected
active processing circuits, and
driver protection voltage
limiters to ensure exceptional
performance and reliability.
The rugged cabinet is
coated with a textured black
finish (carpet covering is
an option) for durability and
ease of handling. The DS-4P
comes standard with six
aircraft pan fittings
(ring and stud), three on the
top and three on the bottom
of the enclosure. L-Track
rigging can be fitted as an
option. Also available is a
variety of hanging and
arraying hardware to create
a complete system.
The DS-4P easily
integrates with the Remote
Monitoring SystemTM (RMS)
network and software
application. Windows-based
RMS displays signal and
power levels, driver and
cooling fan status, limiter
activity, and amplifier
temperature for all net-
worked loudspeakers.
