UPA Compact Loudspeaker

Return to Previous Page

Product Description


The UPA loudspeakers provide high power output, low distortion, and consistent polar response in a compact, vented two-way enclosure for exceptional fidelity and extended high-frequency performance.


The Constant-Q horn affords uniform response throughout the coverage area, be it wide (UPA-1P) or narrow (UPA-2P). In addition, extraordinarily flat amplitude and phase response allow for tonal accuracy and precise imaging.


Predictable array performance ensures system design flexibility. Optional rigging frame, mounting yoke and pole mount adaptors allow fast, flexible installation and easy aiming.

(integrates AC, audio and network)

Input Impedance: 10 kΩ differential between pins 2 and 3

Wiring: Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to
provide virtual ground lift at audio frequencies

Pin 3: Signal – (optional polarity reversal switch)6
Case: Earth ground and chassis

DC Blocking: Differential DC blocking up to maximum common mode voltage

CMRR: >50 dB, typically 80 dB (50 Hz – 500 Hz)

RF Filter: Common mode: 425 kHz; Differential mode: 142 kHz

TIM Filter: <80 kHz, integral to signal processing

Nominal Input Sensitivity: 0 dBV (1 V rms, 1.4 V pk) continuous average is typically the onset of
limiting for pink noise and music

Input Level:Audio source must be capable of producing a minimum of +20 dBV (10
V rms, 14 V pk) into 600 Ω to produce maximum peak SPL over
the operating bandwidth of the loudspeaker
