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. Celestion 6-inch woofers provide a tight and ultra responsive low frequency program.
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.
Optional PSA1 Installation Hardware
Yorkville Paraline Series PSA1 cabinets can be flown in any installation quickly, securely and very cost effectively with the addition of optional flying hardware (PSA1RIGKIT) and a proprietary bumper (PSA1FRAME). The PSA1RIGKIT installs directly to the PSA1 without modification to the cabinet using mounting points integrated in the all-metal aluminum cabinet handles. A maximum of four PSA1 cabinets can be arrayed safely using PSA1RIGKIT assemblies. The entire array can then be safely flown using a single PSA1FRAME bumper.
The PSA1FRAME bumper has several flying points to angle the array in simple two-point hangs. The efficient design allows the PSA1 cabinets to be rigged with the frame kit in the field with a minimum of time and effort. The hardware maintains fixed cabinet to cabinet splay angles for seamless vertical coverage.
The Modular PSA1 system can be configured for optimum coverage in most installations quickly and effectively without complicated hardware, or additional external signal processing making it the most cost effective installation solution delivering the performance of a compact vertical array.
A system comprised of two PSA1 cabinets delivers 30°V x 110°H coverage using two PSA1RIGKITs and one PSA1FRAME. A three cabinet 45°V x 110°H array can be created with the addition of one PSA1 and one additional PSA1RIGKIT. A maximum of four cabinets can be configured for specialized installs where a 60°V x 110°H array may be required.
PSA1 Paraline Lens Technology
The heart of the PSA1 design is the high frequency Para-Line lens. Invented by Tom Danley, this innovative 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. It provides an effective impedance transformation while at the same time providing a way to adjust the path length in a continuously variable way, creating a dispersion pattern with the same characteristics as that of a much deeper conventional horn design.
The Paraline Lens eliminates the impractical depth needed to make an array of conventional horns that would sum into a non-interfering source. In the case of the PSA1, a vertical dispersion pattern of 15° is achieved with a Paraline Element less than one inch deep, where a conventional horn would be several metres in length.
Innovative Multiple Woofer Configuration
Four 6.5-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).
Paraline systems can, by design, be scaled for applications. A simple system using two PSA1 full range cabinets and one PSA1S subwoofer can easily be configured for larger events with additional subwoofers and cabinets. Up to two PSA1 cabinets can be mounted on a single standard heavy duty speaker stand or subwoofer pole for additional coverage and volume. For larger arrays or permanent installations, up to four PSA1's can be arrayed using optional flyware brackets.
Solid 5/8-inch plywood is used in all Paraline series subwoofers to ensure maximum performance, making them the ideal foundation for whatever cabinet configuration you choose for the mid/high component of your 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 Paraline Series Subwoofers can be easily integrated in to virtually any PA application, making it one of the most versatile active subwoofer solutions Yorkville Sound currently offers.
