RCF HDL 20-A: Compact Line-Array Power with Fast, Field-Ready Deployment
The RCF HDL 20-A is a true active line-array module built for touring reliability and rapid setup. A 1400 W peak (700 W RMS) Class-D amplifier drives dual 10" woofers for solid low-mid punch and a large-format compression driver with a 3" voice coil for high-definition vocals. A powerful onboard DSP provides selectable presets that adapt the array to indoor rooms, high-curvature hangs, and clustered deployments—keeping coverage smooth and intelligible without external processing. Variable, tour-grade mechanics and a composite PP enclosure with structural wood reinforcement deliver strength without excess weight, simplifying truck pack and rigging.
Input and output are standard XLR, with Powercon power linking for clean cable runs. With 100° horizontal coverage, 15° vertical module geometry, and a crossover at 800 Hz that keeps most of the vocal range on the HF device, HDL 20-A arrays project evenly while preserving clarity at distance. Pair with the flyable HDL 18-AS when extended LF is required.
- Real-World Applications & Sound Roles: Live sound reinforcement for clubs and concert halls; mobile DJ line-array rigs; corporate AV and ballroom coverage; installed systems needing compact, high-SPL performance.
Where the RCF HDL 20-A Excels
- High SPL in a Small Footprint: Up to 135 dB max SPL from a compact, easy-to-truck enclosure.
- Vocal Clarity at Distance: 3" voice-coil compression driver with 800 Hz crossover keeps vocals coherent across the throw.
- Quick Rigging: Tour-grade, safe variable mechanics with integrated flyware speed up array builds and tear-downs.
- Smart Presets Onboard: DSP modes (Cluster, HF, High Curving, Indoor) optimize projection for real venues—no extra processor required.
- Chicago/Mobile DJ Ready: 100° horizontal coverage and fast cabling (Powercon I/O, XLR pass-through) support swift ballroom turnovers.
- Road-Worthy Build: Composite PP cabinet with structural reinforcement and steel grille withstands transport and daily use.
- Reliable Power Platform: Class-D amplification with convection cooling and protective limiting (Thermal, RMS, Soft Limiter) for stable shows.
- System Scalability: Designed to integrate with the flyable HDL 18-AS subwoofer for full-bandwidth arrays.
Control Modes for HDL 20-A
The DSP-controlled input section provides venue-ready presets and protection for consistent performance:
- Presets: Cluster (for tightly packed boxes), HF projection correction, High Curving (steeper splay angles), Indoor (reduces room-gain buildup).
- Crossover: 800 Hz, aligning the system so most vocal content rides the HF driver for improved pattern control.
- Protections & Limiting: Thermal and RMS protection with a soft-knee limiter maintain headroom while safeguarding components.
- Sensitivity & I/O: Selectable -2 dBu / +4 dBu input sensitivity; balanced/unbalanced XLR in/out for straightforward signal flow.
Amplifier & DSP Engine, Built for the Gig
RCF’s high-efficiency Class-D platform delivers 1400 W peak / 700 W RMS with ultra-fast transient response and realistic dynamics. Convection cooling and protective DSP keep performance stable from soundcheck to encore.
Rigging That Speeds Up Your Day
Variable mechanics and integrated flyware support fast, repeatable hangs. The module geometry (15° vertical) and 100° horizontal pattern help you shape arrays for uniform coverage while minimizing setup time.
Cabinet Strength, Touring Practicality
A composite PP enclosure with structural wood reinforcement and a steel grille resists impact and transport wear. Dual side and dual rear handles improve handling on docks, lifts, and ballroom load-ins.
Transducers Tuned for Definition
Two 10" woofers with 2.5" inside-outside voice coils provide efficient, controlled low-mid. A large-format compression driver with a 3" voice coil manages the critical vocal band for intelligibility across the venue.
Connectivity & Power That Stays Tidy
Standard XLR input/output and Powercon IN/OUT streamline linking and power distribution. The result: cleaner cable runs and faster changeovers for DJs, clubs, and live engineers.
How to Deploy RCF HDL 20-A in the Field
Build arrays using the HDL 20-A’s variable rigging to match venue depth and balcony geometry. Use High Curving for steeper splay near the bottom of the hang, and enable HF projection correction when you need extended top-end reach. For indoor rooms, start with the Indoor preset to tame buildup, then fine-tune splay angles for even coverage. When low-frequency extension is required, add HDL 18-AS subs in a flown or ground-stacked configuration aligned to your array height and audience plane. Maintain clean AC daisy-chains via Powercon and keep signal flow consistent through XLR pass-through.
Preset smart, splay right, and the HDL 20-A rewards you with fast setup and consistent, high-clarity coverage.

Frequently Asked Questions — RCF HDL 20-A
What are the core specs for output and bandwidth?
Frequency response is 55 Hz–20 kHz with a maximum SPL of 135 dB (1 m). Horizontal coverage is 100°, with 15° vertical module geometry.
Which DSP presets are available and when should I use them?
Use Cluster for tightly packed arrays, HF for extended top-end projection, High Curving when splay angles are steep, and Indoor to control low-mid buildup in rooms.
What drivers are inside the HDL 20-A?
Two 10" woofers with 2.5" voice coils handle lows/low-mids, and one large-format compression driver with a 3" voice coil reproduces the majority of the vocal band (800 Hz crossover).
What I/O and power connections are provided?
Balanced/unbalanced XLR input with XLR output link, selectable -2 dBu/+4 dBu sensitivity, and Powercon IN/OUT for AC linking.
Is there a recommended subwoofer pairing for DJs and live music?
Yes. The HDL 18-AS is the ideal flyable bass complement when extended low-frequency performance is required.
