The DS-2 is a high-power, arrayable

mid-bass unit designed to supplement

Meyer Sound MSL-3 and MSL-10A loud-

speaker systems in the 50-160 Hz range.

Optimized to perform in a wide range of

large-scale sound reinforcement applica-

tions, the DS-2 delivers high sound pres-

sure levels with extremely low distortion

and offers exceptionally controlled directiv-

ity.The system utilizes two proprietary 15-

inch cone drivers in a folded horn enclo-

sure braced with steel vertical reinforcing

rods. The horn features a hyperbolic flare

for maximum energy transfer with mini-

mum frequency response ripple. Its bal-

anced compression chamber presents a

symmetrical load to the drivers, providing

very high power handling. The rugged,

multiple-ply hardwood cabinet is fitted

with handles and, optionally, aircraft-style

rigging pan fittings.

The DS-2 requires a high-quality profes-

sional power amplifier capable of delivering

600 watts continuously into 4 ohms with a

signal voltage gain of 10 dB (minimum) to

32 dB (maximum), and can accommodate

up to 2500 watts burst power.

Note 1:

Acoustical specifications are

for the minimum configuration

of two DS-2 cabinets, and are

measured on axis at 2 meters

from 1/R image (located at cabi-

net rear).

Note 2:

Half-space conditions, pink

noise input, in third-

octave bands.

Note 3:

Loudspeaker driven with “A”-

weighted noise (peak-to-RMS

ratio

≈

12 dB), with amplifier

rated at 600 W/channel at

4␣ohms. The DS-2 will accom-

modate amplifiers capable of

peak output levels up to

140␣Vpk.

Note 4:

Loudspeaker driven at 2 vrms

(1 watt @ 4 ohms).

Note 5:

ISO™ Input: Pins 1, 2 and 3

are transformer-isolated, and

shell is connected to chassis/

AC earth ground. Pin 3 positive

for positive pressure output.

D-2 Control Electronics Unit

analog OR condition, automatically tracks

the power amplifier with the greatest out-

put voltage swing to control the system

protection limiters.

Also provided is a switch-defeatable

crossover (Mode switch) and line-level out-

put to drive subwoofer systems, with a sub

polarity switch to facilitate aligning the

subwoofers with the main system. The sub

switches and other setup controls are lo-

cated behind a cover plate on the D-2 front

panel, providing a means for securing the

system installer’s presets.

The DS-2 loudspeaker operates as a

system with the D-2 Control Electronics

Unit (one per channel). Optimized for the

DS-2 and pre-aligned at the factory, the D-2

contains active crossover networks, fre-

quency response and phase response align-

ment circuitry, and Meyer Sound’s exclu-

sive SpeakerSense™ driver protection

circuitry, incorporating peak and RMS

signal limiting as well as excursion protec-

tion. A single-channel device operating at

line level, the D-2 is intended to be the

final component in the signal chain before

the power amplifier.

The D-2 SpeakerSense circuitry protects

the DS-2 loudspeaker components from

damage due to overheating or excessive

excursion under high power conditions.

This unique circuit continuously monitors

the power applied to the DS-2 drivers, and

limits the signal output when the safe oper-

ating areas of the drivers are exceeded.

Until the onset of overload, the Speaker-

Sense circuitry has no effect on the signal.

The D-2 SpeakerSense circuit incorpo-

rates Meyer Sound’s new MultiSense™

function, which allows the use of multiple

power amplifiers having different channel

gains and/or power ratings. The D-2 accom-

modates up to four amplifiers, and provides

separate Sense inputs for each. Its
