RCF HDL 30-A: Compact Two-Way Touring Power With Networked Control
The RCF HDL 30-A is an active two-way line-array module built for medium to large events where speed, consistency, and vocal clarity matter. A 2200 W peak / 1100 W RMS Class-D amplifier drives two 10" neodymium woofers and a titanium compression driver with a 1.4" exit and 4.0" diaphragm (ND940) through RCF’s custom 4-PATH waveguide. FiRPHASE running at 48 kHz, 32-bit processing delivers zero-degree phase and ultra-linear amplitude response, while RDNet provides system-wide control and monitoring.
The waveguide maintains a precise 100° × 15° pattern and an isophasic load from 680 Hz up, so arrays hold tone and intelligibility from front row to mix position. With forced cooling, Powercon IN/OUT, XLR audio I/O, and onboard RDNet (Ethercon), HDL 30-A is optimized for quick, repeatable deployments in clubs, ballrooms, corporate AV, and festival rigs. For extended low-frequency capability, pair with the flyable HDL 38-AS.
- Real-World Applications & Sound Roles: Chicago mobile DJ arrays; club and ballroom installs; corporate AV and worship; festival side hangs and delays; touring systems needing fast curvature and predictable coverage.
Where the RCF HDL 30-A Excels
- Touring Output, Compact Form: 137 dB max SPL from a lightweight PP composite enclosure eases lifts and truck pack.
- Coverage You Can Trust: 100° × 15° geometry and 4-PATH waveguide keep response even across wide rooms.
- Vocal Definition at Distance: ND940 titanium driver (1.4" exit, 4.0" diaphragm) and 680 Hz crossover preserve intelligibility.
- Time-Coherent Imaging: FiRPHASE (48 kHz, 32-bit) achieves zero-degree phase and ultra-linear amplitude response.
- Networked Supervision: RDNet control and management for grouping, trims, and device health from a central interface.
- Fast, Ground-First Rigging: Angles can be set on the deck and auto-index when hoisting; start at 0.2° increments.
- Scales With Your System: Up to 20 HDL 30-A per flybar; HDL 38-AS is the ideal flyable bass complement.
- DJ and Ballroom Friendly: Predictable voicings and tidy Powercon/XLR linking accelerate room turnovers.
Control Modes for HDL 30-A
The DSP-controlled section and network features streamline consistent setup show after show:
- Processing Platform: 48 kHz, 32-bit DSP with FiRPHASE for linear phase and natural transients.
- Array Optimization: 680 Hz crossover supports isophasic loading through the waveguide for smooth curvature and throw.
- Protections: Thermal and RMS management with a soft limiter to preserve headroom.
- I/O & Sensitivity: XLR input/output with +4 dBu nominal sensitivity; RDNet Ethercon onboard (bypass/control).
- Power & Cooling: Powercon IN/OUT with forced cooling for dependable performance.
4-PATH Waveguide & 680 Hz Isophasic Handoff
The custom 4-PATH design maintains a precise 100° × 15° pattern while creating an ideal isophasic load from 680 Hz up—keeping vocals focused and response consistent as arrays curve.
FiRPHASE Clarity at 48 kHz, 32-Bit
RCF’s proprietary FiRPHASE filters deliver zero-degree phase and ultra-linear amplitude response, so mixes translate naturally across the audience with minimal latency.
Neodymium Transducers Tuned for Power
Two 10" neodymium woofers with 2.5" voice coils provide controlled low-mid projection down to 50 Hz. The ND940 titanium HF driver (4.0" diaphragm, 1.4" exit) handles detail and headroom for speech and vocals.
Reconfigurable Rigging That Saves Time
Angles set on the ground snap into position when lifting—supporting J-shaped and spiral arrays from 0.2° increments. A single flybar handles up to 20 modules for scalable systems.
How to Deploy RCF HDL 30-A in the Field
Design for uniform SPL: reduce splay angles at the top for throw, increase curvature toward the front rows, and confirm geometry against room depth and trim height. Establish a flat baseline, then use RDNet groups to trim balcony vs. floor zones. When pairing with HDL 38-AS, verify polarity and align delay to lock LF to the flown array. Keep XLR links and Powercon daisy-chains clean to speed turnovers between DJs and live sets.
Set curvature on the deck, verify zones in RDNet, and HDL 30-A delivers fast, repeatable clarity for Chicago events and beyond.

Frequently Asked Questions — RCF HDL 30-A
What is the coverage pattern?
Nominal coverage is 100° horizontal with 15° module geometry. The 4-PATH waveguide helps arrays maintain consistent tonality as curvature increases.
How does FiRPHASE improve clarity?
FiRPHASE at 48 kHz, 32-bit provides zero-degree phase and ultra-linear amplitude response, enhancing intelligibility and imaging across the audience.
Can I network and supervise the system?
Yes. RDNet enables control, grouping, per-zone trims, and device health monitoring from a centralized interface.
What transducers are used?
Two 10" neodymium woofers (2.5" voice coils) for LF/low-mid, and a high-performance ND940 titanium compression driver with a 4.0" diaphragm and 1.4" exit for HF.
What about subs and array size?
HDL 38-AS is the ideal flyable bass complement. Up to 20 HDL 30-A modules can be fastened on a single flybar for scalable coverage.
Share room size, trim height, and program style—AVMaxx will configure an HDL 30-A array that meets your SPL and coverage goals with headroom.
