W8L Longbow
Large Scale, 3-Way Line Array Enclosure
The Martin Audio W8L Longbow is an evolution of the successful W8L line array system. It brings a new level of performance to the most demanding sound reinforcement applications such as outdoor festivals, sports stadiums and the largest arenas.
In the low frequency section, the 15? (380mm) Hybrid bass horn design is responsible for the tight, punchy and extended low frequency performance of the W8L Longbow. Development of a completely new ultra-long excursion driver gives the W8L Longbow the ability to displace almost twice the volume of air as the W8L when driven with the same input signal. This advance lifts the already formidable low-end performance to a new level and extends the low frequency -3dB point down to 35Hz.
The mid-horn of the W8L Longbow utilises 2 x 8? (200mm)/2? (50mm) coil drivers to produce 109dB at 1 metre for a 1 watt input. The twin 8? (200mm) mid-horn geometry and short, toroidal ?donut? phase plug work together to maintain a low curvature Wavefront and wide 90° horizontal coverage pattern of the mid frequencies right up the 2.5kHz crossover point.
Since the launch of the W8L, Martin Audio has developed a patent pending technology, which provides an exceptional degree of control over the curvature of the high frequency vertical wavefront. Our research has shown that even very long throw systems benefit from a small but specific amount of wavefront curvature. By coupling this technology with significant advances in high frequency device design we have created a quad-driver, high frequency system with the very high efficiency of 119dB (1W/1m). This allows the W8L Longbow to cope with the most adverse atmospheric conditions which can severely attenuate high frequencies over long distances. The new high frequency system also results in improved HF summation of cabinets in the array and a corresponding reduction of side lobes.
The proprietary rigging system of the W8L Longbow is quick to deploy and allows a wide range of array curvatures to be achieved as called up by the Display or Viewpoint array optimization software. W8L Longbow columns are hinged at the front for gapfree HF coverage. Inter-cabinet angles from 0° to 7.5° are set by a rotating splay bar at the rear of the enclosure.
W8L Longbow systems are designed to be powered by Martin Audio MA12K amplifiers.

3-Way Downfill Line Array Element
The Martin Audio Wavefront W8LD is a line array downfill enclosure which connects directly to the bottom of a W8L Longbow array and covers from the front row out to up to 20m when using two W8LD cabinets. The exceptionally wide 120° horizontal dispersion increases coverage to front row central and off-stage areas, with full pattern control maintained right up to 15kHz.

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.
