Meyer Sound Reinforcement Loudspeaker UPM-2 Specifications page 4

Architectural and
Engineering Specifications
The ultra-compact, high-power rein-
forcement speaker system shall be a passive
3-way type with two 5-inch low-frequency
loudspeakers, front mounted in a ducted
bass-reflex hardwood plywood enclosure
with a 45 high-frequency waveguide and
titanium dome driver. The enclosure shall
be fitted with three 3 ⁄ "–16 threaded
8
mounting points, and shall operate with
a separate Control Electronics Unit.
The Control Electronics Unit shall con-
tain a power supply capable of operating
from a 120/240V AC 50/60 Hz line, equal-
ization circuitry for amplitude and phase
alignment, protection circuitry which
automatically activates under high power
conditions, RMS limiter which protects
the speakers from overheating, active bal-
anced input, active push-pull output, and
LED indicators for power on and limiters.
Total harmonic distortion at + 26 dBu
at the balanced output loaded with 10k
shall be less than .1% at 1kHz. The "A"-
weighted noise level shall be at least 105 dB

below maximum rated output
of +26 dBu.
The speaker system combined with a
125W (16 ohm rating) amplifier shall
meet the following performance criteria:
Frequency response, 60 Hz to 20 kHz plus
or minus 4 dB measured in half space
at 1 meter on axis with
noise; output of 108 dB SPL measured at
1 meter on axis with peaks of 118 dB SPL
when driven with "A"-weighted noise.
High frequency distribution pattern, 45
degrees horizontal by 45 degrees vertical.
Speaker enclosure dimensions shall be
6 3 ⁄ " W x 18 1 ⁄ " H x 7
4 8
(7.3 kg).
Control Electronics Unit dimensions
shall be 19" W x 1
7lbs (3.2 kg).
The speaker enclosure shall be the Meyer
Sound UPM-2. The Control Electronics
Unit shall be the Meyer Sound P-2.

Meyer Sound Laboratories has
devoted itself to designing,
manufacturing, and refining com-
ponents that deliver superb sonic
reproduction. Every part of every
component is designed and built
to exacting specifications and
undergoes rigorous, comprehen-
sive testing in the laboratories.
Research remains an integral,
driving force behind all produc-
tion. Meyer strives for sound
quality that is predictable and
neutral over an extended lifetime
and across an extended range.
