Technology

Unlike static channel-limited master-slave concepts, all active AIA speakers and AIA amplifiers have their own state-of-the-art, high-performance network DSP control unit. This allows cinema setups to be changed and expanded as needed. Up to now, there isn’t a higher flexibility and future reliability available. The automatic synchronization of all parameters via the dynamic AIA network ensures that all users who access the system simultaneously with their computers or smartphones are always up-to-date. Even if the speakers are connected via classic analogue XLR cabling, every single speaker or amplifier can be operated centrally and in real time via the network.
 

AIA AVB network technology is raising limits.

This technology enables the system to stream audio signals to any number of AIA AVB loudspeakers/amplifiers in a highresolution, loss and interference-free manner. Thereby all AVB devices synchronize themselves with high precision to a master clock. This ensures that all active speakers in the system put the audio data out at exactly the same time. The inherent precision is 0.000000030 s.

Thus, even with the simultaneous use of extremely short (as from 10 cm) and extremely long (up to 100 m) cables, the transmission is completely latency-free. Cable lengths therefore no longer play a role. The shortest cable then can be used to save space. It is exactly this perfect timing that makes the cinematic experience so real, according to the generally accepted rule "the better the time coherence, the more precise the spatial image".

AIA Speaker Management

The AIA technology makes it possible to configure high-precision and enormously effective filters for the loudspeaker drivers in use. Classic passive filters upstream of the drivers are no longer necessary. The direct connection of amplifier and driver as well as the superior filter technology significantly increase the resolution and dynamic performance. Also the very short distance between the electronics unit and the drivers impinges positively on the quality of the sound. In addition, AIA, as a high-end manufacturer, only uses high-quality components and cables.

The quality of the AIA Speaker Management technology is described by Holger Barske, editor-in-chief of Germany's leading analogue magazine LP, as follows: “The "scary discipline" of any digital system the Ascendo masters with ease: no collapsing at very low volume levels, no digital artifacts, even at moonlight levels, the whole performance remains extremely audible and clean. If the future of music reproduction moves into this direction – then bring it on to me!

 

AIA Creator (For Dealers / Installers / Professionals)

With the AIA Creator software even complex installations are centrally, orderly and easily adjusted, managed and monitored.

 

Setup Wizard

The setup wizard makes it quick and easy to set up even large cinema configurations with 32 or more channels. Click on a speaker field, the assigned speaker starts to flash. Push the field into the appropriate position using “drag & drop”. The loudspeaker receives all necessary parameters automatically. It can not be done faster or easier.

 

Calibration of the various loudspeakers

  • Time correction
  • Sound adjustment
  • Room acoustic correction
  • Volume control
  • Gain

 

Group function

After every single speaker has been perfectly adjusted with the Creator's extensive optimization tools, the ingenious Group function adjusts the overall sound of the home cinema.
 

Main group

The Main groups assign to all connected speakers the same changes. If, for example, a recording sounds too dull, the Main group containing all loudspeakers has their treble level raised and the fundamental range lowered. All amplifiers are switched on and off via the Main group. Often, however, only specific cinema speakers need to be changed. For example, all subwoofers are required to play louder and/or the ceiling speakers have to perform a bit more powerful, in order to let the thunderstorm seem more realistic. These changes are effected in the subgroups Front / Surround / HiSurround / Top / Sub. With the Group function even very large installations can be easily and orderly adapted to the existing room acoustics, as well as to the different requirements of different film genres, recording qualities and surround formats. The real-time control makes it possible to make all changes instantly noticeable and also to facilitate the operation.

Coax

Coaxial designs offer the advantages of a single point source for a consistent acoustic centre and a symmetrical dispersion pattern resulting in homogenous reproduction with perfect transient response and highest intelligibility.

Traditional multi-way, non-coaxial speaker designs have long been the way to go in speaker applications. But they suffer from the changing distances between the listener and the speaker elements: When you move around in the coverage area, the sound is inconsistent. Even more troublesome, the crossover point between the drivers can sometimes be audible. This is especially troublesome in a cinema, where the multiple listeners are positioned in a wide horizontal and vertical array.

Coaxial systems solve this by having the drivers on the same axis, thus providing a single point source for a consistent acoustic centre.

This results in symmetry of response on both the horizontal and vertical axis, at any given angle. The crossover transition is seamless (inaudible) at all angles. (By “symmetry,” we mean that whatever response is observed at a given angle with respect to the axis, the same response will be observed at that angle in the opposite direction. The loudspeaker’s behaviour is “mirrored” about its axis.) Non-coaxial loudspeakers are not able to display this symmetry.

 

What is Ethernet AVB/Tsn?

Audio Video Bridging (AVB) was created to solve the problems that have arisen as more consumers get their audio and video content through a home network in addition to or instead of hard media such as CD, DVD and Blu-ray discs. AVB is the next generation of audio/video over Ethernet and other compatible media, such as wireless LAN. It is the common name for the set of technical standards developed by the IEEE 802.1 Audio Video Bridging Task Group and serves as an extension of the IEEE 802.1, 802.3 and 802.11 specifications used for most wired and wireless home networks. AVB combines precise, consistent time synchronization technology with automatic network traffic management that gives priority to audio and video signals on the entire network.

AVB standards add capabilities to the network providing three major enhancements:

  • Precise timing to support low-jitter media clocks and accurate synchronization of multiple audio streams;
  • A simple reservation protocol that allows an application on an endpoint device (speaker) to notify the various network elements in a path so that they can reserve the resources necessary to support a particular media stream; and
  • Queuing and forwarding rules that ensure that such a media stream will pass through the network within the delay specified by the reservation.
