Meyer Sound UMS-1P UMS-1P specifications, architect specifications

UMS-1P specifications

1. Recommended maximum operating

frequency range. Response depends on

loading conditions and room acoustics.

2. Free field, measured with 1/3-octave

frequency resolution at 4 meters.

3. Measured with music at 1 meter.

4. Power handling is measured under AES

standard conditions: transducer driven

continuously for two hours with band-

limited noise signal having a

6 dB peak-average ratio.

5. Two additional input module options

are available with a polarity reversal

switch and an attenuator (0 dB to

-18 dB): one looping and one with two

inputs for mono summing.

6. Amplifier wattage rating based on the

maximum unclipped burst sine-wave

rms voltage the amplifier will produce

into the nominal load impedance. Each

channel 30 V rms (42 V pk) into 4 ohms.

7. 100 V AC version, range 90 - 100 V AC;

recommended maximum 115 V AC.

8. Fuse-protected above 135 V AC (115 V

AC switch position) and 265 V AC (230

V AC switch position).

9. Current drawing for a single

loudspeaker. Loop out not used.

Equipped for two-conductor, twisted-pair network, reporting

amplifier operating parameters to system operator’s host computer.

The loudspeaker shall be a self-powered, sub-bass system able

to be used singly or ground-stacked in multiples. The transducers

shall consist of two 10-inch cone drivers with 2-inch voice coils,

each rated to handle 400 AES* watts.

The loudspeaker shall incorporate internal processing electron-

ics and a two-channel amplifier. Each amplifier channel shall be

class AB/bridged with complementary MOSFET output stages.

Burst capability shall be 450 watts total with a nominal resistive

load of 4 ohms both channels. Distortion (THD, IM, TIM) shall not

exceed 0.02%.

Performance specifications for a typical production unit shall

be as follows: Operating frequency range shall be 25 Hz to 160

Hz. Phase response shall be ±30 degrees from 41 Hz to 155 Hz.

Maximum peak SPL shall be 127 dB at 1 meter. Beamwidth shall be

360 degrees for a single unit. Directional characteristics can be

achieved with multiple cabinets.

Notes:

The audio input shall be electronically balanced with a 10 kOhm

impedance and accept a nominal 0 dBV (1 V rms, 1.4 V pk) signal

(+20 dBV to produce maximum peak SPL). Connectors shall be

XLR (A-3) type male and female. RF filtering shall be provided.

CMRR shall be greater than 50 dB (typically 80 dB, 50 Hz to 500

Hz). Two additional input module options shall be offered with

an attenuator and polarity reversal switch; one with loop-through

output, and another with two summing inputs instead of the loop-

through input and output.

Two versions of the loudspeaker shall be available: a switchable

115/230 V and a non-switchable 100 V version. The voltage

selection needs to be manually selected. The internal power

supply shall perform EMI filtering, soft current turn-on and surge

suppression. Powering requirements shall be nominal 100 (100 V

version) and 110 or 230 V AC (115/230 version) line current at 50

or 60 Hz. UL and CE operating voltage range shall be 115 V AC

- 240 V AC. Ultimate short-term peak current draw shall be 2.9

A at 115 V AC, 2 A at 230 V AC and 3.3 A at 100 V AC. Current

inrush during turn-on shall not exceed 18 A at 115 V AC. AC

power connectors shall be PowerCon with looping output. The

loudspeaker system shall provide facilities for installing the

optional RMS remote monitoring system.

All loudspeaker components shall be mounted in an acoustically

vented rectangular enclosure constructed of premium birch

plywood with a black textured finish. The front protective

grille shall be powder-coated hex-stamped steel covered by

charcoal-gray foam. Dimensions shall be 22.75" wide x 16.30"

high x 17.51" deep (16" without grille) (578 mm x 414 mm x 445

mm; 406 mm without grille). Weight shall be 62 lbs (28.10 kg).

A pole mount for supporting a UPM-1P or UPM-2P shall be

fitted as standard.

The loudspeaker shall be the Meyer Sound UMS-1P.
