Yorkville PSA28 Compact Powered Array with Paraline Lens

Yorkville PSA28: Dual 8" Paraline Compact Line Array with Synergy Horn

The Yorkville PSA28 is a compact dual-8" powered line array loudspeaker that merges tour-grade punch with seamless setup. With 1400W of peak onboard power, IP54 weather resistance, and integrated flying hardware, it's engineered for professional performance indoors or out. At its core are two proprietary technologies developed by Tom Danley—the Paraline Lens and Synergy Horn—which shape the PSA28's 120° x 10° output into a smooth, coherent wavefront without comb filtering across stacked cabinets.

The enclosure combines dual 8” neodymium LF drivers and dual 1” exit neodymium HF drivers in a compact polypropylene shell with perforated steel grille protection. Its internal DSP offers advanced shaping tools including switchable high-pass filtering for subs, high-frequency boost, Nearfield mode for attenuating front-row harshness, and array compensation EQ to balance tonal response across vertical deployments. Rear-panel rotary controls manage gain, mode selection, and rig size.

Connectivity includes balanced XLR input and output, locking powerCON® AC in/out, and resettable circuit protection. The PSA28 also features a 35mm dual-angle pole mount, dual bar handles, and Yorkville’s durable skeletal rigging frame for quick ground stack or flown setups. All components are Made in Canada and optimized for low-distortion clarity at up to 140 dB peak SPL.

• High-SPL line array element for outdoor events or festivals
• Compact flown array module for churches and theaters
• Ground-stacked DJ array for mobile sound reinforcement
• Front-fill or delay array for large-scale PSA1 deployments
• Fixed install solution for arenas, ice rinks, or gymnasiums

Where This System Excels

• Outdoor Performance: IP54-rated enclosure and high SPL make it ideal for festivals, concerts, and seasonal installs.
• Linearity in Array: Paraline Lens delivers consistent vertical coverage without comb filtering.
• High Headroom: 1400W peak power with efficient neodymium drivers for powerful yet clean output.
• Flexible Deployment: Works as standalone, ground-stack, or flown array via integrated skeletal rigging.
• Tour-Ready Build: Locking powerCON connectors, resettable circuit protection, and rugged polypropylene shell.
• Fine-Tuned Controls: Rear-panel filtering and array compensation features optimize system voicing for any configuration.

Control Modes for the Yorkville PSA28

• Gain Control: Master level attenuator with unity reference point for matched operation across arrays.
• High-Pass Filter (w/SUB): Engages a low-frequency roll-off optimized for use with Yorkville PSA subs or other active subwoofers.
• HF Boost: Adds top-end clarity when used outdoors or in high-absorption venues.
• Nearfield Mode: Attenuates high frequencies to reduce harshness when the cabinet is angled toward front-row listeners.
• Array Size Compensation: Smooths frequency buildup in arrays with multiple PSA28 enclosures.

Paraline Lens & Synergy Horn Integration in the PSA28

The PSA28 uses a proprietary combination of Tom Danley’s patented Paraline Lens and Synergy Horn technologies to deliver precisely controlled wavefronts with minimal phase distortion. The Paraline Lens transforms the output of each high-frequency driver into a vertically summed line source, which allows for seamless cabinet-to-cabinet coupling without comb filtering. This means you can deploy multiple PSA28 enclosures in a vertical array while maintaining clarity and coherence across the listening area.

The Synergy Horn geometry ensures that the summation of all driver outputs occurs within the horn itself, creating a true point-source output pattern. This synergy eliminates the need for external processing to align components and provides uniform 120° x 10° dispersion across the PSA28’s full 65 Hz–20 kHz response.

Rear-Panel DSP Control & Array Optimization Modes

While the PSA28 does not rely on an external DSP processor, its integrated control suite provides four voicing and optimization tools accessible via rear-panel switches:

• High-Pass Filter (SUB Mode): Rolls off low-end content for integration with dedicated subwoofers.
• HF Boost: Adds high-frequency presence to increase clarity in reverberant or outdoor spaces.
• Nearfield Mode: Attenuates horn output when aiming downward at close-range audiences, reducing harshness.
• Array Size Compensation: Optimizes low-frequency balance based on the number of stacked enclosures to counteract LF buildup.

Each mode is passive and analog, allowing for quick adjustment in the field without requiring software, laptops, or delay-matched system processors.

Driver Architecture & Rig-Ready Power Section

The PSA28 is powered by a robust Class-D amplifier delivering 1400W peak (1200W program) output across four neodymium drivers: 2x 8” LF and 2x 1” HF. These drivers are purpose-built for long-term performance in high-output environments while reducing weight to 60 lbs (27.2 kg) for rigging applications.

Its powerCON® locking AC connectors, 120VAC input, and resettable 5A breaker deliver a rugged platform for continuous touring use. The IP54-rated polypropylene enclosure and integrated skeletal rigging hardware allow for both pole-mount and flown deployment, ensuring the PSA28 is ready for touring, festivals, or semi-permanent installs.

How to Deploy the Yorkville PSA28 in the Field

The PSA28 offers flexible deployment options tailored to both touring professionals and integrators:

• Ground Stack: Use the integrated skeletal rigging to stack multiple PSA28 units on a Yorkville PSA1S or PSA2S subwoofer base. Ensure the angle between enclosures matches the audience coverage zone.
• Flown Arrays: The enclosure includes built-in flyware rated for safe rigging of vertical clusters. Up to four PSA28s can be suspended using compatible Yorkville hardware or third-party certified trussing.
• Pole Mounting: For smaller venues or front-fill use, the PSA28 includes a dual-angle 35mm pole mount adapter, allowing tilt-back or vertical orientation depending on stage height.
• Array Compensation: Use the onboard "Array Size" switch to optimize low-end balance when linking multiple units in a vertical configuration.
• Subwoofer Pairing: Engage the high-pass filter when pairing with PSA1S or powered subs like the ES18P. This ensures proper crossover behavior and extended system headroom.

Whether flown, stacked, or mounted on poles, the PSA28’s rigging-ready hardware and DSP voicing tools ensure fast, repeatable setups for real-world deployment.
