RCF HDL 30-A Active 2-Way Line Array Module

RCF HDL 30-A Active 2-Way Line Array Module

The RCF HDL 30-A is a professional active two-way line array module designed for medium to large-scale sound reinforcement applications. It combines two 10-inch neodymium woofers, a 1.4-inch titanium compression driver with a 4-inch voice coil, integrated Class-D amplification, onboard DSP processing, FiRPHASE technology and RDNet control in a compact composite enclosure.

With a manufacturer-rated 2200 W peak amplifier, 1100 W RMS total power, and maximum SPL of up to 137 dB, the RCF HDL 30-A provides substantial acoustic output from a relatively compact 25 kg enclosure. RCF specifies a frequency response of 50 Hz to 20 kHz, a 100-degree horizontal coverage angle, and a 15-degree vertical coverage angle. 

The system is particularly suited to professional sound companies, touring productions, concert applications, corporate events, festivals, live entertainment and fixed or temporary installations where controlled coverage, high output and networked system management are important.

Unlike a conventional point-source loudspeaker, a line array module is designed to operate as part of a larger array. Multiple RCF HDL 30-A modules can be mechanically coupled and configured to create a scalable sound reinforcement system. The integrated array fittings make the enclosure suitable for professional flown configurations when used with the appropriate RCF-approved rigging hardware and procedures.

High Output From a Compact Line Array Module

One of the defining characteristics of the RCF HDL 30-A is the amount of acoustic output available from its relatively compact enclosure. RCF rates the module at up to 137 dB maximum SPL at 1 metre, while the integrated amplifier section provides 2200 W peak power and 1100 W RMS total power.

The amplifier architecture divides the available power between the low-frequency and high-frequency sections. RCF specifies 1600 W peak for the low-frequency section and 600 W peak for the high-frequency section. The HF section is rated at 300 W RMS, while the LF section is rated at 800 W RMS. 

This integrated amplification eliminates the requirement for a separate external amplifier rack dedicated to each loudspeaker module. The amplifier, DSP and loudspeaker components are engineered together as a complete active system.

For rental companies and production businesses, this can simplify system deployment and reduce the amount of external amplification required in comparison with passive loudspeaker systems.

Two 10-Inch Neodymium Woofers

The RCF HDL 30-A uses two 10-inch neodymium woofers with 2.5-inch voice coils. The dual-woofer configuration provides the low-frequency and low-midrange section of the two-way design while maintaining a relatively compact cabinet format.

Neodymium magnet assemblies allow RCF to achieve the required transducer performance while keeping the overall enclosure weight under control. The complete loudspeaker weighs approximately 25 kg, according to RCF’s published specifications. 

The two 10-inch drivers work together with the system’s waveguide and DSP architecture to provide controlled output across the intended operating range.

For professional sound reinforcement, the physical format of the enclosure is important. A system that delivers significant output while remaining manageable for technicians can make a difference during loading, transportation, rigging and system deployment.

1.4-Inch Titanium Compression Driver

High-frequency reproduction is handled by a 1.4-inch neodymium compression driver with a 4-inch voice coil.

The large 4-inch voice coil is part of the HF driver design used in the system, while the compression driver works with the loudspeaker’s waveguide to provide controlled high-frequency dispersion.

RCF specifies a crossover frequency of 680 Hz, allowing the low-frequency and high-frequency sections to operate as an integrated two-way system. 

The combination of the dual 10-inch low-frequency section and compression driver creates a format designed specifically for line array deployment rather than conventional standalone point-source operation.

137 dB Maximum SPL

The RCF HDL 30-A is rated for up to 137 dB maximum SPL at 1 metre.

Maximum SPL is one of the important specifications to consider when evaluating professional loudspeakers, but it should not be interpreted as the expected continuous operating level in every application. Actual system performance depends on array size, acoustic environment, processing, operating conditions, program material, configuration and other factors.

For professional users, the 137 dB rating demonstrates the output capability specified by the manufacturer and positions the system for demanding sound reinforcement applications.

When multiple modules are used together in an appropriately designed array, the system can be scaled to suit the requirements of larger events and venues.

50 Hz to 20 kHz Frequency Response

RCF specifies a frequency response of 50 Hz to 20 kHz for the RCF HDL 30-A. 

This makes the module a full-range line array element within its intended system configuration, although professional deployments frequently combine line array modules with dedicated subwoofers when additional low-frequency extension and output are required.

RCF identifies the HDL 38-AS as a bass complement for the HDL 30-A system. The HDL 38-AS is a dedicated subwoofer designed to extend the low-frequency performance of an HDL system. 

For events requiring significant low-frequency impact, pairing the line array with an appropriate subwoofer system allows the HDL 30-A modules to concentrate on their intended operating range while dedicated low-frequency enclosures handle the sub-bass requirements.

100-Degree Horizontal Coverage

The RCF HDL 30-A provides a manufacturer-specified horizontal coverage angle of 100 degrees. Its vertical coverage is specified at 15 degrees. 

The relatively wide horizontal dispersion makes the system suitable for applications where broad audience coverage is required.

Vertical coverage in a line array is highly dependent on the number of modules used and their mechanical angles. The 15-degree specification should therefore be understood as part of the individual module’s acoustic characteristics rather than as a complete description of the coverage pattern of an entire flown array.

Proper array design remains important when deploying professional line array systems. The number of cabinets, inter-cabinet angles, trim height, aiming, venue geometry and processing all affect the resulting coverage.

FiRPHASE Technology

The RCF HDL 30-A incorporates RCF’s FiRPHASE technology.

FiRPHASE is part of the DSP architecture used by RCF to manage phase behaviour and time-domain response. The technology is designed to contribute to coherent reproduction and controlled system response.

The integrated DSP operates at 48 kHz with 32-bit processing, according to RCF’s published specifications. 

For professional system designers, integrated DSP processing is an important part of an active loudspeaker because the amplifier, transducers and processing can be treated as a complete system rather than as independent components.

RDNet Control and Management

Another major feature of the RCF HDL 30-A is integrated RDNet compatibility.

RDNet provides network-based monitoring and management for compatible RCF systems. The HDL 30-A includes RDNet connectivity through its EtherCON connections and provides onboard RDNet functionality. 

For professional production companies, networked control can be particularly useful when a system contains numerous loudspeaker modules. Instead of relying entirely on physical access to individual cabinets, technicians can use the appropriate RCF network infrastructure and software environment to manage compatible systems.

This can be valuable for large event deployments, touring systems, installations and rental inventories where multiple loudspeaker modules need to be monitored and configured efficiently.

Professional Connectivity

The RCF HDL 30-A provides XLR and RDNet EtherCON connections for signal and network connectivity. RCF specifies an input sensitivity of +4 dBu. 

Power is handled through PowerCON input and output connections, allowing compatible power distribution arrangements to be used throughout a professional system.

The combination of signal input, signal output, network connectivity and power linking is designed around the practical requirements of professional sound reinforcement systems.

Integrated Protection and DSP

The RCF HDL 30-A incorporates thermal and RMS protection along with a soft limiter.

Protection systems are particularly important in active loudspeakers because the amplifier and transducers are integrated into the same enclosure. The onboard processing helps protect the system under demanding operating conditions while maintaining the intended system response.

The unit also provides preset control and an RDNet bypass function. 

For rental companies and touring professionals, integrated protection reduces the number of external processing components that have to be managed as part of the loudspeaker system.

Lightweight PP Composite Enclosure

Despite its output capabilities, the RCF HDL 30-A weighs approximately 25 kg, or 55.12 lbs.

The enclosure is manufactured from PP composite material and incorporates integrated array fittings and two side handles. RCF specifies dimensions of approximately 293 mm high, 705 mm wide and 502 mm deep. 

The compact dimensions and relatively low weight are useful considerations for professional production companies. Every kilogram matters when a system is being transported, loaded, flown, dismantled and stored repeatedly.

The enclosure also features a steel grille and black finish.

Designed for Professional Touring and Events

The RCF HDL 30-A is intended for professional sound reinforcement and is particularly suited to applications where scalable coverage and high output are required.

Typical applications can include:
• Concert sound reinforcement
• Touring productions
• Festival PA systems
• Corporate events
• Large conferences
• Outdoor events
• Indoor venues
• Live entertainment
• Rental and production companies
• Professional mobile sound systems
• Fixed or temporary installations

The exact number of modules required depends on the venue, audience size, required SPL, coverage objectives, subwoofer configuration and system design.

For professional deployments, the HDL 30-A should be installed, flown and operated according to RCF’s documentation and applicable safety requirements.

Building an RCF HDL 30-A System

One of the advantages of a modular line array is scalability.

A single module can be used as part of a smaller system, while multiple RCF HDL 30-A cabinets can be combined into larger arrays when additional output and vertical control are required.

The system should not simply be assembled by stacking cabinets without considering the acoustic requirements of the venue. A professional line array deployment should account for audience geometry, trim height, array curvature, coverage, system gain structure, low-frequency integration and mechanical safety.

For larger systems, the appropriate rigging hardware and manufacturer-approved procedures should always be used.

RCF HDL 30-A With Subwoofers

Although the RCF HDL 30-A reaches down to a manufacturer-specified 50 Hz, professional productions may require substantially more low-frequency output than a line array module alone is designed to provide.

This is where dedicated subwoofers become important.

RCF identifies the HDL 38-AS as a flyable bass complement for the HDL 30-A system. The HDL 38-AS is an 18-inch active subwoofer designed specifically for professional system integration with the HDL platform. 

A properly designed HDL system can therefore combine flown line array modules with dedicated low-frequency enclosures to create a complete full-range PA system.

The exact ratio of tops to subwoofers depends on the application and should be determined from the required acoustic output and system design.

Why Choose an Active Line Array?

An active line array system integrates the loudspeaker drivers, amplification and DSP into the enclosure.

With the RCF HDL 30-A, the user receives a complete active two-way module rather than a passive cabinet requiring a separate external amplifier.

This has several practical advantages for professional audio companies.

The amplification is already matched to the transducers. DSP processing is integrated. Protection is integrated. Network management is available through RDNet. Signal and power connections are designed for professional system deployment.

For rental companies, these features can simplify system preparation and reduce the amount of external amplification hardware required for each deployment.

Suitable for Rental Companies

The RCF HDL 30-A can make sense for professional rental inventories where a scalable active line array is required.

A rental company can build systems around the number of modules available and configure them according to different event requirements.

For example, a smaller corporate production may require a relatively compact array, while a larger outdoor event may require additional modules and dedicated subwoofers.

The integrated amplification and network control can also make system setup more consistent between different events.

For companies that regularly supply concerts, festivals, corporate productions and touring systems, having a professional active line array platform can provide flexibility across different types of work.

Suitable for Touring Applications

Touring systems demand equipment that can deliver high output while remaining manageable for transportation and deployment.

At 25 kg per module, the RCF HDL 30-A provides a relatively compact format for a professional line array enclosure.

Its integrated handles, array fittings, PowerCON connectivity, XLR connections and RDNet networking are all relevant to touring and production workflows. 

The system can be transported as individual modules, configured into arrays at the venue and managed through the appropriate control infrastructure.

For touring professionals, equipment selection should always consider not only acoustic performance but also transportation, rigging, serviceability, replacement parts, system compatibility and the availability of appropriate accessories.

Professional System Integration

The RCF HDL 30-A is not simply a high-powered loudspeaker. It is an integrated system containing transducers, amplification, DSP, protection and network management.

This means that system designers can approach deployment as a complete platform.

The dual 10-inch low-frequency section handles the lower portion of the operating range, while the 1.4-inch compression driver covers the high-frequency section. The DSP manages the system’s internal processing, while FiRPHASE technology is incorporated into the signal-processing architecture.

RDNet adds a network management layer for compatible professional applications.

Together, these technologies allow the HDL 30-A to function as part of a larger professional sound reinforcement ecosystem.
