APPENDIX B: UPQ-1P SPECIFICATIONS
36
TIM Filter <80 kHz, integral to signal processing
Nominal Input Sensi-
tivity
0 dBV (1 V rms, 1.4 V peak) continuous average is typically the onset of limiting for
noise and music
Input Level Audio source must be capable of producing +20 dBV (10 V rms, 14 V peak) into 600 Ω
to produce maximum peak SPL over the operating bandwidth of the loudspeaker
AMPLIFIER
Type Two-channel complementary MOSFET output stages (class AB/H)
Output Power 1275 W total (1 x 1000 W, 1 x 125 W)
Note: Wattage rating is based on the maximum unclipped burst sine-wave rms
voltage the amplifier will produce into the nominal load impedance.
Total Output 2550 W peak
Note: Peak power based on the maximum unclipped peak voltage that the amplifier
will produce for at least 100 milliseconds into the nominal load impedance.
THD, IM TIM <.02%
Load Capacity 2 Ω low channel, 8 Ω high channel
Cooling Convection at low to mid audio levels; fan-assisted only at high audio levels
Note: The fan is controlled by audio level. It remains off at turn-on and at low to mid
audio levels. Operating only at high audio levels makes it virtually inaudible.
AC POWER
Connectors PowerCon with looping output or VEAM all-in-one (integrates AC power, audio, and
network)
Voltage Selection Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety Agency Rated
Operating Voltage
95 V AC - 125 V AC; 208 V AC - 235 V AC; 50/60 Hz
Turn On/Turn Off
Points
85 V AC – 134 V AC; 165 V AC - 264 V AC
Note: 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.
Current Draw
Idle Current 0.5 A rms (115 V AC); 0.28 A rms (230 V AC); 0.56 A rms (100 V AC)
Maximum Long-Term
Continuous Current
3.9 A rms (115 V AC); 2.0 A rms (230 V AC); 4.4 A rms (100 V AC)
Burst Current 7.0 A rms (115 V AC); 3.9 A rms (230 V AC); 8.2 A rms (100 V AC)
Note: AC power cabling must be of sufficient gauge so that under burst current rms
conditions, cable transmission losses do not drop voltage below specified operating
range at the speaker.
Ultimate Short-Term
Peak Current
18.0 A peak (115 V AC); 10.5 A peak (230 V AC); 20.0 A peak (100 V AC)
Inrush Current 6.0 A peak (115 V AC); 8.4 A peak (230 V AC); 7.1A peak (100 V AC)
Note: Current draw for a single loudspeaker. Loop output not used.
PHYSICAL
Enclosure Multi-ply hardwood
Finish Black textured
Protective Grille Powder-coated, hex-stamped steel black mesh screen
Rigging Aluminum end plates on top and bottom with metric M10 threaded points; integral 1-
1/2" (38 mm) pole mount receptacle on bottom
