Meyer Sound UPL-1 Manuel utilisateur

radial horn housed in a vented

cabinet. An active crossover,

optimized pole-zero response

correction filters, loud-

speaker element protection

circuitry and dual power

amplifiers are built directly

into the enclosure.

Both UPL-1 drivers are of

a proprietary design and are

individually factory-tested for

maximum linearity. The high-

frequency horn driver is of an

entirely new configuration,

employing a titanium dome

The Meyer Sound UPL-1 is a

self-contained, high-definition

powered loudspeaker that is

suitable for a wide variety of

high-quality sound reinforce-

ment applications. It is

optimized to approximate a

true point-source radiator

within its coverage area, and

features a frequency response

of ±2 dB from 50Hz to 18 kHz.

The UPL-1 comprises a 10-

inch cone low-frequency driver

and 1-inch high-frequency

driver with 90°by 40°modified

FEATURES

and fabric suspension in a

patented, low distortion design

(U.S. patent number

4,152,552). It is coupled to

a modified radial horn that

provides excellent directivity

control with wide horizontal

high-frequency coverage.

The UPL-1’s power am-

plifiers utilize complementary

power MOSFET output stages

in a class AB configuration.

Input sensitivity is switchable

to either +4 dBu or -10 dBV.
