Description

Product Description

SURPRISING POWER IN A COMPACT PACKAGE

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.

EXCEPTIONAL MEYER SOUND TECHNOLOGY

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.

MAKES DESIGNING A BREEZE

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

Audio Input

Type:Differential, electronically balanced

Maximum Common Mode Range:±15 V DC, clamped to earth for voltage transient protection

Connectors: Female XLR input with male XLR loop output or VEAM all-in-one
(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 2: Signal +
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
