Ref. code: 1.02.424

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


The RCF HDL30-A is a compact bi-amped 2-way active touring system for medium to large events, both indoors and outdoors. It features two 10-inch woofers and an impressive 4-inch titanium compression driver. The time coherent waveguide is the result of in-depth research and design. HDL 30-A is the first line array in a composite cabinet with zero-degree phase and ultra-linear amplitude response. The built-in 2200 watt class-D amplifier delivers excellent playback clarity and up to 137 decibels SPL max. The RCF HDL30 -A features state of the art RCF transducers with neodymium magnets. Considering its acoustical power, it has a remarkably low weight for easy handling and flying. The HDL 38-AS is the ideal flyable bass complement for the HDL 30-A array system.

4-Path Waveguide

The custom 4 PATH designed waveguide allows a precise coverage of 100 x 15 degrees, while also delivering an excellent, linear high-frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from 680 Hz to the highest audible frequencies.

Powerful Class D Amplifier

RCF`s Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. HDL amplifiers deliver a ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the HDL amplifiers present SMPS power supply section to produce maximum output and minimum weight.

New Perspective On Linearity

RCF speakers are designed using a proprietary and advanced FiR filtering technology, conceived to deliver transparent sound, absolute clarity and perfect stereo images to the listener.
The special FiRPHASE filters allow to achieve coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies to the system.

Used RCF


RCF S.p.A. is a widely recognized Italian manufacturer of high performance audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors (DSP).
RCF is an Italian audio products manufacturer founded in 1949. The first products sold were microphones and electroacoustic transducers (loudspeakers).
In the late ’60, concert sound was going electric, and many loudspeaker pioneers were searching for high-powered devices to use in their designs.
RCF was one of the first European OEM suppliers for international brands, thanks to the experience built on high power transducers.
After few years, thanks to the in-depth know-how in loudspeaker technology, RCF begin to develop and produce sound reinforcement systems under the same brand.
The introduction of the ART Series, in 1996, has established RCF among the few global manufacturers of active loudspeakers.
The TT+ High Definition - Touring and Theater series equipped with DSP, introduced in 2004, and the RDNet Networked Management technology, let RCF a full recognition in the professional audio market.
Since 2017, all DSP active speakers incorporate FiRPHASE technology, which allows achieving a 0° linear phase playback.
RCF is the first audio manufacturer to have a complete catalogue of 0° phase-compatible sound systems including line arrays.

Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.

Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.

Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.

Package: A completed and fully edited audio piece.

Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.

Phase: Time relationship between signals it’s all relative.

Power Output: A measure, usually in watts, of how much energy is modulated by a component.

Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.

Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.

Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.

Pre/Pro: A combination preamp and surround processor.

Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.

Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.

Q-and-A: Question and answer session.

Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.

Reverberation: The reflections of sound within a closed space.

RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.

RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.

SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.

Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.

Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.

Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.

Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.

Simultaneous Interpretation: This system allows attendees to hear the meeting in their own language.

Sound Bite: A portion of audio of someone speaking.

Sound field: The total acoustical characteristics of a space, such as ambience number, timing, and relative level of reflections ratio of direct to reflected sound RT-60 time etc.

Soundstage: The area between two speakers that appears to the listener to be occupied by sonic images. Like a real stage, a soundstage should have width, depth, and height.

Speaker: A component that converts electrical energy into acoustical energy.

SPL: Sound-Pressure Level. Measured in dB.

Subwoofer: A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz.

THX: Certification program for home theater equipment. Uses some proprietary features, but mostly assures a base quality level for a given room size. (See THX select or Ultra.) Is compatible with any and all soundtrack formats. Stands for either Tom Holman’s eXperiment, after the engineer who drafted the original standard, or is named after the company’s founder George Lucas first movie, THX 1138. Nobody agrees on which.

THX select: Certification program for speakers and receivers that assures a base level of quality and performance when played in a room that’s between 2,000 and 3,000 cubic feet.

User-Generated Content (UGC): Text, photos, video or audio supplied by the customers of a company.

Voicer: A radio report without background audio taken from a scene or otherwise.

Wrap: A radio report containing both the reporter and an actuality.
