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