The loudspeaker shall be a self-powered, full-range
system. The transducers shall consist of a 10-inch diameter
cone driver and a 3-inch diaphragm compression driver on
a 80° x 50° horn. The horn shall allow rotation to provide
the wider coverage pattern in either the horizontal or
vertical plane relative to the cabinet’s vertical axis.
The loudspeaker system shall incorporate internal
processing electronics and a two-channel amplifier.
Processing functions shall include equalization, phase
correction, signal division, and driver protection for
the high- and low-frequency sections. The acoustical
crossover point shall be 2 kHz. Each amplifier channel
shall be class AB/bridged with complementary MOSFET
output stages. Burst capability shall be 300 watts total into
a nominal load of 4-ohms low channel and 16-ohms high
channel. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit
shall be as follows, measured at 1/3 octave resolution:
Notes:
Operating frequency range shall be 55 Hz to 20 kHz. Phase
response shall be ±45° from 750 Hz to 18 kHz. Maximum
SPL shall be 128 dB at 1 meter. Coverage (-6 dB points)
shall be 80° x 50°, horizontal or vertical dependent on
horn orientation.
The audio input shall be electronically balanced with a
10 kΩ impedance and accept a nominal 0 dBV (1 V rms, 1.4
V pk) input signal. Connectors shall be XLR (A-3) type with
male input and female loop-through output. RF filtering
shall be provided, and CMRR shall be greater than 50 dB
and typically 80 dB (50 Hz – 500 Hz).
The internal power supply shall perform automatic voltage
selection, EMI filtering, soft current turn-on and surge
suppression. Powering requirements shall be nominal
100 V, 115 V or 230 V AC line current at 50 Hz or 60 Hz
frequency. Current draw during burst (<1 sec) shall be
5 A at 115 V, 2.5 A at 230 V and 5.8 A at 100 V. Current
inrush during soft turn-on shall not exceed 15 A at 115 V.
AC power connector shall be a locking connector with
looping output.
The loudspeaker system shall provide facilities
for installing Meyer Sound’s optional RMS remote
monitoring system.
All loudspeaker components shall be mounted in an
acoustically vented trapezoidal enclosure constructed
of premium birch plywood with a hard black textured
finish. The front protective grille shall be powder-
coated hex-stamped steel. Dimensions shall be 11.15"
wide x 22.43" high x 12.25" deep (283 mm x 570 mm
x 286 mm). Weight shall be 46 lbs (20.87 kg). Integral
high-strength, 6061-T6 aluminum top plates with
threaded M8 metric holes shall accommodate Meyer
Sound proprietary rigging hardware and third-party
accessories.
The loudspeaker shall be the Meyer Sound UPJ-1P.
1. Recommended maximum operating
frequency range. Response depends
upon loading conditions and room
acoustics.
2. Measured with 1/3 octave frequency
resolution at 4 meters.
3. Measured with music at 1 meter.
4. The UPJ horn can be rotated to
provide an 80° x 50° coverage
pattern in either the horizontal or
vertical plane.
5. At this frequency, the transducers
produce equal sound pressure levels.
6. The driver is coupled to an 80° x 50°
constant-directivity horn.
7. 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.
8. Two additional input module options
are available with polarity reversal
switch and an attenuator (0 dB to
-18 dB): one looping and one with
two inputs for mono summing.
9. Amplifier wattage rating based
on the maximum unclipped burst
sine-wave rms voltage the amplifier
will produce into the nominal load
impedance. Low and high channels
30 V rms (42 V pk).
10. No automatic turn-off voltages.
Voltages above 265 V AC are fuse
protected but may cause permanent
damage to the power supply.
Voltages below 90 V AC may result in
intermittent operation.
