HDL 50-A

Active 3-Way Line Array Module

The HDL 50-A is a true active high power speaker system ready to use touring system for large events, indoors and outdoors. Equipped with 2x12” woofers, 4x symmetrical 6.5” midranges and two 2” drivers, it offers excellent playback quality and high sound pressure levels with a built in 2200W RMS powerful digital amplifier that delivers superior SPL, while reducing energy requirement. Using advanced neodymium magnets and a groundbreaking new housing constructed from lightweight plywood and polypropylene, it has a remarkably low weight for easy handling and flying.

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.

V-Shaped Symmetrical Design

The symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL 50-A take care of the constant directivity without spots of break up or attenuation. The originally designed V-SHAPED front baffle provides:

  • Coplanar midranges and woofers
  • Controlled LF dispersion
  • Central space to host the HF guide
4-Path Waveguide

The custom 4PATH designed waveguide allows a precise coverage of 90 x 10 degrees, while also delivering a superb, linear high frequency response. The unique shape of the four ducts forming the guide create an ideal isophasic load from 700 Hz to the highest audible frequencies.

Neodynium RCF Precision Transducers

HIGH FREQUENCIES - The two ND 840 large format compression driver deliver one of the key advantages of the HDL 50-A: the 3.0” voice coil allows a crossover point of 800 Hz and therefore this driver can produce almost all of the vocal range. This allows better coverage and superior efficiency.
MID FREQUENCIES - 4 x 2.0” voice coil 6.0”neo midranges - Water resistant fiber doped cone - Polycotton M-roll surround - High power magnetic structure
LOW FREQUENCIES - 2 X 3.0”voice coil neodymium 12” woofers - Water resistant fiber doped cone - Polycotton M-roll surround - Hypervented magnetic structure

Equalizer: A component designed to alter the frequency balance of an audio signal. Equalizers may be graphic, parametric, or a combination of both. Fade: A gradual increase in audio, i.e. a fade-up, or a gradual decrease in audio, i.e. a fade-down.Feedback: The transmission of current or voltage from the output of a device back to the input, where it interacts with the input signal to modify operation of the device. Feedback is positive when it's in phase with the input and negative when it's out of phase. Frequency: The number of cycles (vibrations) per second. In audio, audible frequencies commonly range from 20 to 20,000 cycles per second (Hz). In video, frequency is used to define the image resolution. Low-frequency video images depict large objects or images. Higher frequencies depict smaller objects (finer details). Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz, 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level. Full-Range: A speaker designed to reproduce the full range (20 Hz to 20 kHz) of audio frequencies.Gain: Increase in level or amplitude.Gooseneck: This refers to amicrophone with a flexible neck that is most frequently attached to a podium or lectern. It is designed to allow the speaker to raise or lower the microphone to a suitable height.Graphic Equalizer: A type of equalizer with sliding controls that creates a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies; lowering sliders cuts (attenuates) the affected frequencies.High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.Incue/Inq/In-Point: These words all refer to the initial few seconds of audio signifying the beginning of the production.Impedance: A measure of the impediment to the flow of alternating current, measured in ohms at a given frequency. Larger numbers mean higher resistance to current flow.KHz: Kilohertz or one thousand Hz.Lavaliere: A small microphone that attaches to clothing, allowing the speaker to have a hands-free presentation.Line Array: A group of speakers that have been arrayed or “built up” in the vertical or horizontal plane, which allow for a highly consistent sound field. A Line Array is perfect for medium to large audiences.Midbass: The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies. Midrange: The middle of the audio frequency range. Also used as a term for loudspeaker drivers designed to reproduce this range. Mixer: This is the unit in which audio signals are directed from. A mixer provides for both mic and line input combinations while allowing you to control one or more outputs.MP3: MPEG-1 Audio Layer-3. Compression scheme used to transfer audio files via the Internet and store in portable players and digital audio servers. Natural Sound (NATS): The nonverbal audio that occurs in a non-studio setting. NATS can be used to help characterize the setting.Noise: An unwanted portion of a signal such as hiss, hum, whine, static, or buzzing.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.surround processor portion of the receiver and the input of the amplifier portion of the receiver.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.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. 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 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. 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.
