Yorkville PSA1 & PSA2 Line Array System
The Yorkville PSA1 & PSA2 Line Array System, delivers a Compact Size and Unique Clarity through the Patented Horn Precision Coverage with exceptional response!
Yorkville Sound PSA1
Yorkville Sound's Paraline Series active full range loudspeaker system
delivers the clarity and precision of a complex line array system in a
compact, user friendly format. Innovative cabinet design uses Yorkville
Sound’s proven Paraline high frequency lens technology pioneered in our
flagship VTC Elevation Series line array cabinets.1
Two BMS 1.75-inch compression drivers mounted to the patented Paraline
lens delivers a focused 15-degree vertical dispersion and wide 110
degree horizontal coverage. Four high quality 18 Sound 6-inch woofers
provide a tight and ultra responsive low frequency program.
PSA1 Paraline Lens Technology
The heart of the PSA1 design is the high frequency Para-Line lens.
Invented by Tom Danley, this patented technology transforms a point
source into a uni-phase plane wave, allowing multiple high frequency
drivers to sum coherently in the vertical plane without
self-interference. This innovative design provides an effective
impedance transformation while at the same time adjusting the path
length in a continuously variable way creating a dispersion pattern with
the same characteristics as that of a much deeper conventional horn.
The Paraline Lens eliminates the impractical depth needed to make a
conventional horn that would sum into a non-interfering source needed
for multiple cabinet arrays. In the case of the PSA1, a vertical
dispersion pattern of 15° is achieved with a Paraline lens less than one
inch deep, where a conventional horn design would need to be several
metres in length.
Yorkville Sounds PSA2
The Yorkville Sound's Paraline Series PSA1, is a 4800-watt (peak – 2400 watt program) dual 15-inch active subwoofer, with bass
reflex, ideal companion sub for the PSA1 full range
loudspeaker system. Solid 15mm birch plywood cabinet construction and an
integrated all-metal pole-mount adaptor make the PSA2S the perfect
platform for stacking PSA1 cabinets in a scalable array system.
Efficient Class-D power amplifier design provides unmatched long-term
reliability in the field. Cable of direct connection to any audio source
(including speaker level input) the PSA2S can be easily integrated in
to virtually any PA application, making it one of the most versatile
active subwoofer solutions Yorkville Sound currently offers.
Heavy Duty Precision Stand Adaptor - The PSA2S Subwoofer uses Yorkville
Sound’s new Heavy Duty Precision Stand Adaptor. In order to minimize top
cabinet sway and provide an improved standmount platform for multiple
PSA1 cabinets, the PSA2S subwoofer standmount adaptor uses an extremely
thick walled cast aluminum stand receiver with a wider mounting plate
than has been used on Yorkville subwoofers in the past.
Precision machining after casting allows the highest tolerances
possible, this new improved stand adaptor provides a more stable, highly
secure pole mount system for mobile Paraline systems when used in
combination with the Yorkville SW-TUBEHD Heavy Duty all steel subwoofer
