AIRLINE LA-Series
Our commitment to advanced technology
AIRLINE LA-Series line array systems present our commitment to advanced technology offering high fidelity sound, even wide-dispersion characteristics and extreme high spl optimized for use in professional touring applications such as open air concerts, festivals and arenas as well as sound installations in stadiums, houses of worship, large clubs, theatres and musicals.
At the heart of the Coda Audio AIRLINE LA-Series LineArrays is the unique 4-inch planar wave driver. Coda Audio developed a unique driver technology to radiate a coherent planar wave front from a rectangular piston without internal diffraction for superior dispersion control and high fidelity sound. The driver contains a high energy neodymium magnet system and a unique annular ring diaphragm. The ring diaphragm works similar as a wound 140 mm long ribbon diaphragm providing linear frequency response up to 20 kHz.
The advanced driver design allows perfect acoustical coupling of individual units to create a virtually continuous and truly coherent line source.
The AIRLINE LA12 is a 3-way symmetrical high output line array module, designed for large venues where high fidelity sound and outstanding intelligibility is required.
State-of-the-art drivers
Low: The cabinet contains two 12? neodymium ultra low distortion cone drivers covering the 50 Hz - 400 Hz range. The double 12'' long excursion drivers contain high flux linear motors with triple demodulation rings for ultra low distortion and increased power handling.
Mid: Our goal was to generate very high resolution and high dynamic range. To achieve this we developed a special transducer which works in the mid range as a pure piston without the breaking up modes typical for direct radiating small cone drivers. Another aim was to increase the sensitivity and get outstanding headroom in the very important middle range. The AIRLINE LA12 contains four 3.5'' voice coil neodymium mid range drivers with unique ring diaphragms covering the 350 Hz - 1700 Hz range. Loaded to advanced hyperbolic lenses they achieve very high sensitivity of 116 dB 1 W / 1 m above 300 Hz. This means that the drivers need less power to produce enormous high spl and work almost at less than 10% of their nominal power handling. Therefore the ability to reproduce peaks is unique and is practically only limited by the electronics. This patented design is a result of extensive dedicated research and development resulting in near zero power compression, dramatic improvement in dynamic response, clarity and transparency.
High: The three 4' HF planar wave drivers contain unique annular ring diaphragms to radiate a coherent planar wavefront without internal diffraction. This distinctive technology allows perfect acoustical coupling for superior dispersion control and high fidelity sound.
Coherent wavefront
The tri-axial V-arrangement of the low, mid and high frequency drivers ensures coherent coupling between all components. The high frequency planar wave drivers are mounted in the middle, close to the mid-range hyperbolic lenses. The twin 12'' drivers are optimally placed to provide a constant horizontal directivity above 200 Hz. This arrangement combines the energy produced from all 9 transducers to perform as a single source achieving a coherent and uniform wavefront.
Application:
The modules are designed to be used in multiples with a minimum configuration of six. Up to 24 units can be arrayed to achieve extreme high levels needed for the largest venues. The use of SC8 / SC8F subwoofers increases the low frequency response. The integrated rigging system allows quick and easy flying or ground stacking. Arrays may be built straight or curved in various angles to obtain the desired vertical coverage. The Coda EASE Focus simulation software allows you to calculate the perfect setup for every application. Designed for large scale touring and installation applications the AIRLINE LA12 is perfectly suited for open air, stadiums and large theatres where outstanding output capability and low power compression are needed. Applications include sports venues, stadiums, large theatres and large houses of worship, touring and open air festivals.

SC8
Sensor controlled subwoofer with versatile pattern control
The Feedback loop controlled subwoofers have clear advantages over conventional subwoofers when it comes to sonic performance, output and size.
The advanced design aligns several new technologies for outstanding performance.
Key technologies
- Award winning sensor controlled technology
- Feedback loop control , ultra low distortion, very extended and controlled response
- Long excursion 18'' woofers with integrated velocity sensor
What is the Velocity Feedback Loop Comparator?
The specially designed 18'' driver includes a built in 'velocity sensor' that measure precisely the movement of the voice coil. The ?velocity sensor, sends information to the Comparator about velocity, excursion and speed of the voice coil (using XLR cable). The comparator unit of the C10 compares the original input signal to the movement measurement from the 'velocity sensor' and adjusts the amplifier driving voltage and/or current so that the diaphragm moves the way it should move. This compensates in real time for the non linearity of the speaker/ cabinet.
Reduced group delay
This is a big issue that is most often overlooked in conventional designs. The feedback comparator technology offers great advantages in the time domain. In fact the upper bass and the very low frequency are time aligned which means they are reproduced at the same time resulting in extremely accurate and musical bass reproduction.
Transducers
The Sensor controlled subwoofers are equipped with extremely long excursion 18'' neodymium ultra low distortion woofers with integrated velocity sensors that measure, compare and control cone movements. The neodymium motor delivers extreme high magnetic flux for increased efficiency. The 4'' voice coil is 50 mm high, ensuring ultra linear excursion of 40 mm / pp at consistent magnetic force. State of the art carbon-fiber cone ensure maximum stiffness and low moving mass. Three aluminum shorting rings reduce inter-modulation distortion; minimize induction variation while reducing thermal compression. This design reduces dramatically the distortion of a typical subwoofer at longer excursion levels, and improves the overall sound quality and performance characteristics of the cabinet. The sensor is in fact an additional voice coil connected to the loudspeakers voice coil in a high precision, magnetically shielded system.
Electronics and Cabling
The Coda Audio C10 amplifier provides integrated power and feedback loop control solution for the Sensor controlled subwoofers. The unit has two amplifier channels as well as two comparators connected to a 5-pol Neutrik XLR input. The comparator?s electronic circuit loop measures the voice coil excursion of the driver and corrects the signal, significantly decreasing distortion. The unit is set for flat frequency response down to 25 Hz (-6 dB).

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.
