Product file
The UPA-1P loudspeaker provides high power output, low distortion,
and consistent polar response in a compact, vented two-way enclosure.
The loudspeaker features a 12-inch cone low-frequency driver
and a 3-inch diaphragm compression driver
coupled with a 100° horizontal by 40° vertical constant-Q horn.
The versatile UPA-1P has a variety of sound reinforcement applications
including as a main front-of-house loudspeaker in small- to mid-sized venues
and as a fill loudspeaker in larger system.

Low FrequencyOne 12-inch cone driver; 2 Ω nominal impedanceHigh FrequencyOne 3-inch compression driver; 16 Ω nominal impedance
TypeDifferential, electronically balancedMaximum Common Mode Range±15 V DC,
clamped to earth for voltage transient protection
Connectors5XLR 3 female input with male loop output; optional XLR 5-pin connectors to accommodate both balanced audio and RMS signals.
Input Impedance10 kΩ differential between pins 2 and 3
WiringPin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequenciesPin 2: Signal + Pin 3: Signal –
(optional polarity reversal switch)Pin 4: RMSPin 5: RMSCase: Earth ground and chassis
Nominal Input Sensitivity0 dBV (1.0 V rms) continuous is typically the onset of limiting for noise and music
Input Level Audio source must be capable of producing of +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker
