W8LC
The Martin Audio W8LC is a compact line array enclosure designed to bring superb next-generation line array performance to concert, theatre and commercial events. It meets the need for a high power, high bass impact system that is versatile and scalable for a very wide range of applications in the live sound, corporate and fixed installation fields. W8LC grids allow systems to be flown or ground stacked as required. Though compact in size, the W8LC is a full-bandwidth system and may be used without subwoofers in many applications. Where additional low frequency extension is required, W8LCs may be complemented by the W8LS Line Array subwoofers, WLX horn and reflex loaded subwoofers or WSXa horn loaded subwoofers.
Following the all-horn design philosophy of the full-size W8L Longbow, the W8LC is a 3-way system that combines line array principles with innovative horn loading techniques to produce a very powerful compact line array with impressive dynamic impact.
The low frequency section of the W8LC comprises a horn loaded 12" (300mm)/3" (75mm) coil neodymium driver that is reflex loaded to extend the LF output to below the natural cut-off point of the horn. This Hybrid technique marries the very high efficiency of horn loading with the extended low frequency response of a reflex enclosure.
The mid horn of the W8LC utilizes 2 x 6.5" (165mm)/1.5" (38mm) coil, maximum efficiency drivers to produce 106dB at 1m for a 1W input - a significant efficiency gain over direct radiator systems.
The W8LC's HF section comprises three 1" horn elements to produce a low-curvature vertical wavefront with an efficiency of 109dB at 1m for a 1W input. This optimal HF curvature enables W8LC enclosures within the array to be splayed up to 7.5° without introducing gaps in the HF vertical coverage.

W8LCD
The Martin Audio W8LCD is a compact, wide dispersion,vertically arrayable enclosure. It can be used individually and in small quantities for short to medium throw (<40m) applications as well as a downfill element for the W8LC. Its 20° vertical dispersion requires fewer cabinets to cover the same area as a conventional line array element, yet it still benefits from the smooth, predictable coverage of a vertically coupled system.
Using one or two W8LCD cabinets at the bottom of a W8LC array benefits the whole system. The W8LC array becomes less curved and throws further and the W8LCD's 120° dispersion is now covering front row central and the extreme front left and right. Configuring the system in this way requires 2x3 processor channels and three amplifiers to drive up to four cabinets, two per left and right column. It is also possible to adapt the six-way controller settings used with W8LC arrays to incorporate the drive required by the W8LCD.
As a stand-alone enclosure, the W8LCD is effective in arrays of 1 to 4 cabinets when used over short to medium (<40m) distances and coverage areas that require a large vertical angle. To optimise SPL from the front to the rear of the coverage area, the W8LCD is fitted with a rear mounted amplitude shading switch. This boosts output from the top of the array where throw distance is typically greatest and cuts output from the bottom of the array where cabinets may be close to the front of the audience.
The W8LCD is a full-bandwidth system (-3dB @ 60Hz) and may be used without subwoofers in many applications. Where additional low frequency extension is required, it is ideally complimented by the WLX subwoofer from which the W8LCD can be flown or ground stacked. It can also be used with the other Wavefront series subs such as the WSXa, W8LS and WS218X
Constant directivity (in the horizontal plane) horns are used for high and mid frequencies, ensuring consistent on and off axis performance. The high frequency horn generates the correct vertical wavefront curvature to provide optimum inter-cabinet summation and to seamlessly integrate with W8LC arrays. Extreme high frequency output is maintained right out to the edges of the 120° coverage pattern thanks to the patent pending HiBlade device. The mid horn features our patented (US6950530) toriodal phase bung and generates the vertical low curvature wavefront essential for optimum inter-cabinet summation.

Active: Powered. An active crossover is electrically powered and divides the line-level signal prior to amplification. An active speaker includes an active crossover and built-in amplifier.
Actuality: Audio from an announcer speaking.
Amplifier: A component that increases the gain or level of an audio signal.
Balanced Input: A connection with three conductors: two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of connection is very resistant to line noise.
Bandpass: A two-part filter that cuts both higher and lower frequencies around a center band. A bandpass enclosure cuts high frequencies by acoustic cancellation and low frequencies by natural physical limitations on bass response.
Bandwidth: In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output. Bandwidth can also refer to the transmission capacity of an electronic communications device or system the speed of data transfer,is very important when planning a meeting for the attendees to stay connected.
Bass: Low frequencies those below approximately 200 Hz.
Bi-Wiring: A method of connecting an amplifier or receiver to a speaker in which separate wires are run between the amp and the woofer and the amp and the tweeter.
Boost: To increase, make louder or brighter opposite of attenuate.
Bridging: Combining two channels of an amplifier to make one channel that more powerful. One channel amplifies the positive portion of an audio signal and the other channel amplifies the negative portion, which are then combined at the output.
CD: Compact Disc. Ubiquitous digital audio format. Uses 16-bit/44.1-kHz sampling rate PCM digital signal to encode roughly 74 or 80 minutes of two- channel, full-range audio onto a 5-inch disc.
CD-R: Recordable Compact Disc.
CD-RW: Rewritable Compact Disc.
Channel: In components and systems, a channel is a separate signal path. A four-channel amplifier has at least four separate inputs and four separate outputs.
Coloration: Any change in the character of sound (such as an overemphasis on certain tones) that reduces naturalness.
Crossover: A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter.
Crossover Frequency: The frequency at which an audio signal is divided. 80 Hz is a typical subwoofer crossover point and is the recommended crossover point in theatrical and home THX systems. Frequencies below 80 Hz are sent to the subwoofer signals above 80 Hz are sent to the main speakers.
Cut: To reduce, lower opposite of boost.
Decibel (dB): A logarithmic measurement unit that describes a sound`s relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. A 1dB difference over a broad frequency range is noticeable to most people, while a 0.2dB difference can affect the subjective impression of a sound.
Delay: The time difference between a sonic event and its perception at the listening position (sound traveling through space is delayed according to the distance it travels). People perceive spaciousness by the delay between the arrival of direct and reflected sound (larger spaces cause longer delays.
Diaphragm: The part of a dynamic loudspeaker attached to the voice coil that produces sound. It usually has the shape of a cone or dome.
Diffusion: In audio, the scattering of sound waves, reducing the sense of localization. In video, the scattering of light waves, reducing hot spotting, as in a diffusion screen.
Digital Audio Server: Essentially a hard drive, a digital audio server stores compressed audio files (like MP3 or WMA). Most include the processing to make the files, and all have the ability to play them back.
Direct-Stream Digital: A format for encoding high-resolution audio signals. It uses a 1-bit encoder with a sampling rate of 2,822,400 samples per second (verses 44,100 for CD). Used to encode six high-resolution channels on SACD.
Dispersion: The spread of sound over a wide area.
Distortion: Any undesired change in an audio signal between input and the output.
DNR: Dynamic Noise Reduction. A signal-processing circuit that attempts to reduce the level of high-frequency noise. Unlike Dolby NR, DNR doesn't require preprocessing during recording.
Dolby B: A noise-reduction system that increases the level of high frequencies during recording and decreases them during playback.
Dolby C: An improvement on Dolby B that provides about twice as much noise reduction.
Dolby Digital: An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, center, right front, left surround, right surround, and LFE) into a single bitstream, which can be recorded onto a DVD, HDTV broadcast, or other form of digital media. When RF-modulated, it was included on some laser discs, which requires an RF-demodulator before the signal can be decoded. Five channels are full-range the .1 channel is a band-limited LFE track. A Dolby Digital processor (found in most new receivers, preamps, and some DVD players) can decode this signal back into the 5.1 separate channels. Most films since 1992`s Batman Returns have been recorded in a 5.1 digital format, though a number of films before that had 6-channel analog tracks that have been remastered into 5.1.
Dolby EX: An enhancement to Dolby Digital that adds a surround back channel to 5.1 soundtracks. The sixth channel is matrixed from the left and right surround channels. Often referred to as 6.1. Sometimes referred to as 7.1 if the system uses two surround back speakers, even though both speakers reproduce the same signal. Software is backwards-compatible with 5.1 systems, but requires an EX or 6.1 processor to obtain additional benefit.
Dolby Pro Logic: An enhancement of the Dolby Surround decoding process. Pro Logic decoders derive left, center, right, and a mono surround channel from two-channel Dolby Surround encoded material via matrix techniques.
Dolby Pro Logic II: An enhanced version of Pro Logic. Adds improved decoding for two-channel, non-encoded soundtracks and music.
Driver: A speaker without an enclosure also refers to the active element of a speaker system that creates compressions and rarefactions in the air.
DSP: Digital Signal Processing. Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.
DTS: Digital Theater Systems. A digital sound recording format, originally developed for theatrical film soundtracks, starting with Jurassic Park. Records 5.1 discrete channels of audio onto a handful of laser discs, CDs, and DVDs. Requires a player with DTS output connected to a DTS processor.
DTS ES: An enhanced version of the 5.1 DTS system. Like Dolby's Surround EX, a sixth channel is added. In some cases (DTS ES Discrete), the sixth channel is discrete. Software is backwards-compatible with 5.1 systems, but requires an ES or 6.1 processor to obtain additional benefit. Neo: 6 is a subset of DTS ES that creates 6.1 from material with fewer original channels.
Dynamic Range: The difference between the lowest and the highest levels in audio, it&'s often expressed in decibels. In video, it's listed as the contrast ratio.
