The Meyer UPA-P Series self- powered loudspeakers (UPA-1P, UPA-2P) are more than powered versions of the Meyer UPA-C Series (UPA-1C, UPA-2C). The UPA-P Series features phase- corrected electronics that produce flat acoustical phase and amplitude responses, resulting in exceptional system impulse response and precise imaging. Despite the inclusion of amplification and control electronics, the UPA-P is the same size as, and only 10 lb. heavier than the UPA-C. Additionally, the UPA-PÕs advanced horn designs achieve a consistent polar response

and smooth arraying behavior.
The beam width of a horn is the angle at which the sound pressure at a given frequency decreases to half (Ð6 dB) its on-axis amplitude. Existing technologies produce horns whose beam width varies over the operating frequency range. These horns also display non- uniform frequency response within, and significant side lobe energy outside their beam width. Both undesirable characteristics, particularly prevalent for horns with a wide beam width, make array design extremely problematic.
The UPA-P horns exhibit constant Q: the beam width remains consistent across the hornÕs operating frequency range in both the vertical and horizontal planes. The UPA-2P uses the same horn as the UPA-2C: the original design achieved constant Q for its narrow beam width (45¡H x 45¡V). Meyer Sound developed
the UPA-1P horn in an anechoic chamber by measuring coverage patterns using angular and frequency resolutions of 1¡ and 1Ú36 octave, respectively. The UPA-1P horn provides a much wider horizontal, and slightly narrower vertical beam width (100¡H x 40¡V) than the UPA-2P. Both speakers share the following remarkable attributes:
¥uniform frequency response within the beam width
¥rapid and uniform amplitude attenuation for all frequen- cies outside the beam width
¥minimal side lobes
The UPA-P Series is ideally
suited for small PA applications requiring complete coverage with a compact, high-powered system, and also make excellent under-balcony, down- fill.
The UPA-PÕs integrated electronics employs the Intelligent AC power supply, which auto-selects the correct
operating voltage (facilitating international use), suppresses high voltage transients, and provides soft-start power-up (eliminating high inrush current).
The UPA-P can be equipped to operate with the Remote Monitoring Systemª (RMS) network and software application. The UPAÕs are shipped with one of two audio input and control options. The Basic module contains an XLR input and a loop connector. The second module provides features that facilitate array building and integration into full-range systems without incurring the cost of external processors. These inter- changeable modules can be installed in the field with a Phillips screwdriver. RMS displays signal and power levels, driver and cooling fan status, limiter activity, and amplifier temperature for all speakers in the network on a Windows-based PC.
