Yorkville PSA1

The Yorkville PSA1 is a Paraline Series 1200-Watt Compact Full Range Active Loudspeaker.

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.

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.Paraline Element

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.

Innovative Multiple Woofer Configuration

Four 6-inch high power woofers mounted on the “V” shaped front baffle /horn utilize the entire front surface area of the cabinet to increase loading on the drivers and control pattern coverage at lower frequencies. This unique four woofer design increases power handling while reducing power compression by spreading the work load out over four long excursion voice coils and heat sinks (magnets).

Designed for Live Sound in the Real World

Rugged injection molded ABS cabinet and Neodymium magnet woofers minimize overall cabinet weight making a full system transport and set-up can easily be handled with a single operator. Designed to deliver maximum performance with minimum complication, the PSA1’s integrated power amplifiers and internal DSP mean no external processing is required. Direct connect to mixer source and set system levels, and the system is ready for the show.

Highly efficient amplifier design means each PSA1 draws less than 3 amps in typical operation meaning up to four cabinets can operate safely on a standard 15 amp service. This allows efficient set up using AC loop thru connections on the PSA1 while avoiding nuisance tripping of mains breakers. This also minimizes the need for multiple extension cables or access to multiple house circuits often needed for an active PA setup.

Ideal for mobile PA applications in venues where access to complex trussing or roof hangs isn’t practical, the Yorkville PSA1 cabinet mounts quickly and securely on a typical speaker stand. Innovative dual position stand mount offers two potential cabinet angles for expanded setup options. Up to two PSA1 cabinets can be stacked safely and securely on a single traditional stand.
