PSA1 Powered

Speaker

Thank you for choosing Yorkville’s PSA1 compact line array speaker. Designed from the ground up, the PSA1 represents the pinnacle of clarity and output in a compact speaker system. The PSA1 excels in sound reinforcement applications where a line array is desired but cannot be easily accommodated. Used alone

or with the matching PSA1s subwoofer, the PSA1 is designed to deliver reliably at a profes- sional level night after night.

Cabinet Features

The PSA1 is constructed of high strength ABS plastic – a lightweight alternative to a wooden cabinet. At the heart of the PSA1 is a Paraline lens loaded with a pair of 1-inch compression driv- ers along with four 6-inch woofers mounted on a 110°H x 15°V constant directivity horn. Paraline technology was first developed for Yorkville’s flagship VTC Pro Audio Elevation series line array. By channeling the sound waves along equidistant paths, the Paraline lens converts the point source compression drivers into a line source with constant phase and amplitude. The result is a completely balanced sound field and coverage pattern across the cabinet’s horizontal and vertical planes.

The PSA1 features a two position pole stand adapter. When using a single cabinet on a stand, place the speaker at the 0° position. When two cabinets are to be stacked, place the bot- tom cabinet at –7.5° and secure the top cabinet to the bottom cabinet with the safety lanyards tethered to handles of the box.

WARNING: Always use the safety lanyards when stacking cabinets. Failure to do so can result in the top cabinet accidentally tipping off the stack.

WARNING: The safety lanyards and handles are not to be used as rigging hardware in hanging applications. For hanging installation applications, contact your Yorkville dealer for details regarding flying hardware.

Electronic Features

Innovative DSP processing is used to drive the 1000-Watt Class-D woofer amplifier and the two-tier 200-Watt horn amplifier.1 An active crossover for the amplifiers ensures that the woofer and horn operate optimally; meanwhile, separate non-defeatable limiters protect those drivers from excessive peaks and over-powering. The drivers themselves are sourced from the world’s premier manufactur- ers offering an extended lifetime of smooth, powerful performance. We are confident you will find the PSA1 a worthy mainstay for all of your sound application needs.

1. Power Switch and Indicator

The green power LED illuminates when the power switch is turned to the On position and AC voltage is supplied.

2. AC Input and Output

As a standard, the AC inlet on the PSA1 accepts locking IEC power cords. There is also an AC outlet that can be used to loop power through to other cabinets in your array using a male to female looping power cord. Check with your local Yorkville dealer for availability of these accessory cords.

Warning: Do not exceed a total load of 10 A on the looping AC chain.

1Amplifier power ratings are based on peak measurements into a resistive load with the internal limiters disabled.
