HL-50A vs. HL-50A 4K Key Distinctions
Both the HL-50A and HL-50A 4K represent the flagship 3-way line array technology, featuring identical high-resolution driver components (dual 12" neo woofers, four 6.0" midranges, and dual 1.4" titanium compression drivers with 3.0" voice coils) and full RDNet remote management. The core difference lies in their power platform and amplifier architecture:

- HL-50A (Standard Flagship): Features a Tri-amped configuration delivering 2200W RMS / 4400W Peak power with a maximum SPL of 140 dB. It is designed for large-scale venues, theaters, and standard outdoor music festivals.

- HL-50A 4K (High-Power Flagship): Upgrades to a Quad-amped drive system with an impressive 4000W RMS / 8000W Peak output, pushing the headroom to 143 dB Max SPL. The added 3 dB output represents twice the acoustic energy, ensuring uncompromised clarity, minimal distortion at high output, and maximum throw distance required for stadium-scale events and high-impact EDM festivals.

4. Selection Guide for 4 Typical Application Scenarios

Scenario 1: Cost-Effective / Medium-Scale Event Rental
Equipment Combo: HL-20A + SUB A8006 (Optional Flown Sub: HL-18AS)
 

Key Features:
- Classic Powerhouse: Combining dual 10" full-range array modules with dual 18" high-power subwoofers delivers exceptionally high SPL output.
- Streamlined Deployment: No computer networking required. High-pass filters and EQ settings are configured directly via rear-panel physical encoders, making it ideal for standard production companies requiring rapid setup and teardown.
 

Scenario 2: Fully Networked Mid-Size Portable / Dynamic System
Equipment Combo: HL-28A + SUB A9004 (Optional Flown Sub: HL-36AS)
 

Key Features:
- Lightweight & Transparent Vocal Projection: Dual 8" array modules are extremely lightweight and easy to fly, while single 18" neodymium subwoofers offer easy handling.
- Cardioid Subwoofer Integration: Utilizing the RDNet interface on the SUB A9004, sound engineers can easily configure cardioid subwoofer arrays with a single click, drastically reducing low-frequency rear spill onto the stage. Perfect for high-end theaters, Livehouses, and corporate galas.
 

Scenario 3: Professional Touring / Theaters & Major Music Festivals
Equipment Combo: HL-30A + HL-38AS (Flown Array Integration) + SUB A9006 (Ground-Stacked)

Key Features:
- 2-Way Design & FiRPHASE 0° Linear Phase: Large 4" voice coil compression driver paired with dual 10" woofers keeps vocals pristine, dry, and uncompressed even under heavy drive.
- Official Mechanical Alignment: For ground stacking, use the official STCK-KIT HL-30A accessory locked directly onto the SUB A9006. For flown deployment, connect the HL-38AS directly to the HL-30A array using quick-lock pins for seamless low-frequency coupling. The entire system supports real-time central monitoring via RDNet.
 

Scenario 4: Stadium Concerts / Major EDM Festival Sub-Bass Setup
Equipment Combo: HL-50A + HL-53AS (Flown Array Integration) + SUB A9007 (Ground-Stacked)

Key Features:
- Extreme SPL & Sub-Bass Extension: HL-50A provides 140dB+ long-throw capability, while the SUB A9007 utilizes dual 21" neodymium woofers to deliver physical chest-thumping impact extending down to 20 Hz.
- Dedicated Structural Accessories: Employs the official STCK-KIT HL-50A accessory to securely lock HL-50A enclosures on top of the SUB A9007, ensuring structural integrity for heavy ground stacks.
 

A single Line Array may be used on a tripod stand  or on a pole  over  subwoofers.

HL-20A compatible Subwoofers:
SUB A8004 - SUB A8006 - HL-18AS

HL-30A with 8006, 9006 and 9007 series, fix the optional accessory to M20 female screw on the upper part of the sub.
