Meyer Sound DS-2 - Manual (Page 4)

Architectural and
Engineering Specifications DS-2/D-2
The mid-bass loudspeaker system shall
be of the folded-horn type with two 15"
cone loudspeakers in symmetrical compres-
sion chambers. The drivers shall be se-
curely mounted in the trapezoidal hard-
wood-plywood enclosure, and the loud-
speaker shall operate with a companion
Control Electronics Unit.
The Control Electronics Unit shall con-
tain a power supply capable of operating
from a 100-120/200-240V AC, 50/60 Hz
line, electronic crossover circuitry, RMS
limiters which protect the speakers from
overheating, true excursion limiters to pro-
tect the speakers from excessive excursion,
equalization circuitry, active balanced in-
put, indicator LED’s for power on and lim-
iters. A separate, switch-defeatable sub-
woofer output having switchable polarity
shall be provided. Total harmonic distor-
tion shall be less than 0.1%. The protection
limiters shall be controlled by sensing con-
nections to the power amplifier output, and
the Control Electronics Unit shall accom-
modate four separate amplifiers having dif-
fering gains and/or power ratings, with ana-
log OR circuitry to track the amplifier with
greatest output swing. “A” weighted noise
level shall be at least 90 dB below maxi-
mum rated output of +26 dBu.
Two speaker systems, when combined
with the Control Electronics Unit and a
power amplifier rated at 600 watts into
4␣ohms, shall meet the following criteria:
Frequency response, 50 to 160 Hz plus or
minus 3 dB measured with 1 ⁄
3
octave noise,
136 dB SPL of continuous pink noise out-
put at 1 meter and peaks of 148 dB SPL.
Speaker enclosure dimensions shall be
21 1 ⁄
4
W x 56 3 ⁄
4
" H x 30" D, weight 250 lbs
(113.6 kg).
Control Electronics Unit dimensions
shall be 19" W x 1 3 ⁄
4
" H x 7 3 ⁄
4
" D, weight 8
lbs (3.6 kg).
The horn loudspeaker system shall
be the Meyer Sound DS-2. The Control
Electronics Unit shall be the Meyer
Sound D-2.
Meyer Sound Laboratories has
devoted itself to designing,
manufacturing, and refining com-
ponents that deliver superb sonic
reproduction. Every part of every
component designed and built to
exacting specifications and
undergoes rigorous, comprehen-
sive testing in the laboratories.
Research remains an integral,
driving force behind all pro-
duction. Meyer strives for sound
quality that is predictable and
neutral over an extended lifetime
and across an extended range.
