Audio System Description
Discovery Theatre
Alaska Center for the Performing Arts
Anchorage, Alaska
CENTER CLUSTER
The Discovery is a standard square proscenium theatre with an approximate seating capacity
of 800. The proscenium is 48 ft. wide at deck level and 23 ft. high. The main cluster is located at the
top of centerline behind a transparent fascia. The cluster consists of 3 UPA-2P self-powered
loudspeakers. The Meyer UPA-2P self-powered speakers are comprised of: one 12-inch cone driver
and one 3-inch diaphragm compression driver; phase-corrected, optimized control electronics and a
two-channel amplifier (350 W rms/ch). The gain structure between the control electronics and the
amplifier is perfectly matched. The UPA-2P produces flat acoustical phase and amplitude response,
full-range bandwidth, precise imaging, and exceptional system response. The UPA-2P supplies a
maximum SPL of 132.5 db at 1 m with excellent intelligibility, without distortion or coloration
commonly exhibited by small PA speakers. The cabinets are aimed at the mezzanine and back of the
orchestra level.
