Meyer Sound DS-4P - Manual

R

➪

P

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

AC

TM

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 System

TM

(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.
