RCF HDL 6-A Active Line Array Module | FiRPHASE DSP

HDL 6-A Compact Line Array Power for Chicago Rooms

Small box, real throw. The RCF HDL 6-A concentrates touring output into a lightweight 2-way module that speeds ballroom flips and club changeovers. A 1400 W two-channel Class-D amplifier and 48 kHz / 32 bit processing drive a 1.7 in voice coil neodymium compression driver on a precise 100x10 waveguide, time-aligned with 2 x 6.0 in neodymium woofers for up to 131 dB.

FiRPHASE processing handles crossover, phase correction, limiting, and protection for consistent tone from load-in to last track. A symmetrical cabinet keeps coverage consistent as arrays curve, while the PP composite enclosure (structurally reinforced) and rear aluminum handles keep weight to 11.6 kg for fast deployment.

With XLR input/link, +4 dBu sensitivity, and PowerCON IN/OUT, the HDL 6-A drops cleanly into mobile DJ rigs, club installs, and corporate A/V. Pair with the flyable HDL 12-AS for compact full-range hangs.

Real-World Applications and Sound Roles

• Chicago DJ mains for ballrooms, lofts, and lounges
• Club installs needing wide horizontal, tight vertical control
• Corporate A/V arrays, outfills, and delays
• Portable festival side hangs where speed matters
• Flown HDL 6-A plus HDL 12-AS compact full-range systems

Where the RCF HDL 6-A Excels

• Fast Load-Ins: 11.6 kg per module with two rear handles keeps turnarounds tight for weddings and club takeovers.
• Intelligibility at Distance: 1.7 in VC driver on a 100x10 waveguide projects vocals clearly to the back of the room.
• Headroom on Tap: 1400 W two-way amplification supports up to 131 dB without harshness.
• Consistent Coverage: Symmetrical design maintains tone as arrays curve for different audience zones.
• Smart Processing: FiRPHASE with 48 kHz / 32 bit DSP handles crossover, phase, limiting, and protections.
• Clean Cabling: XLR in/link and PowerCON IN/OUT simplify long daisy-chains on busy stages.
• Built for Chicago DJs: Wide horizontal pattern keeps energy on the dance floor in narrow rooms.

Control Modes for RCF HDL 6-A

• HF correction: Tailors top-end balance by distance or application.
• DSP core: FiRPHASE at 48 kHz / 32 bit manages crossover, phase alignment, EQ, limiting, and protections.
• Protections: Thermal and RMS safeguards maintain show-safe operation.
• Limiter: Soft Limiter preserves headroom while preventing overdrive artifacts.
• I/O and sensitivity: Balanced XLR input with XLR link; nominal input sensitivity +4 dBu.
• Power: PowerCON IN/OUT with convection cooling for silent, reliable performance.

Amplifier and DSP Engine

A 1400 W two-way Class-D platform (LF/HF) is governed by FiRPHASE at 48 kHz / 32 bit. The processor executes the 900 Hz crossover, phase correction, soft limiting, and thermal/RMS protections for consistent results at event levels.

Transducers and Coverage

High frequencies come from a 1 x 1.0 in exit, 1.75 in voice coil neodymium compression driver on a precise 100x10 waveguide. Low end is handled by 2 x 6.0 in neodymium woofers (2.0 in voice coils) for tight punch and controlled low-mid body.

Enclosure and Mechanics

The PP composite cabinet is structurally reinforced with integrated array fittings, a steel grille, and two rear handles. Finish options: black or white to match install aesthetics.

Connectivity and Power

XLR input and XLR link operate at +4 dBu for easy integration. PowerCON IN/OUT supports tidy AC runs; convection cooling keeps operation quiet for corporate and worship settings as well as DJ events.

How to Deploy RCF HDL 6-A in the Field

Safety first: Use trained personnel, verify rigging parts, and keep the area below clear. Confirm pickup position and angles before the lift.

• Flown arrays: Use the HDL 6 fly bar and quick-lock pins; set pick-up position (A/B) and splay angles per design. Within rated limits, arrays can include up to 16 x HDL 6-A (configuration dependent).
• Ground-stacked: Stack on compatible subs (for example, HDL 12-AS) with the stacking bar; maximum 6 modules. Verify stability for each layout.
• Pole mounting: With approved hardware, up to 3 modules per pole; confirm pole payload and stability.
• AC daisy-chains: PowerCON linking supports up to 6 modules at 230 V or 3 modules at 115 V per chain.
• Preset setup: Engage HF correction for distance/room behavior; the DSP manages crossover, phase, limiting, and protections.
• Signal discipline: Feed balanced XLR at +4 dBu; keep runs in-phase and away from EMI sources.

Match curvature and HF contour to audience geometry, and keep element counts within rated safety factors for uniform tonality front to back.
