Förster Audiotechnik Electronics With Fibre Optics


























The FA.KA 1 forms the data distribution and control centre of the FA audio system. This is where the audio signals arriving from the various digital sources such as the SACD drive and the audio PC are selected for playback, set to an appropriate level and transmitted in I2S format to the amplifiers. Audio signals, which do not arrive via the optical cables in a jitter-free I2S format that transports the audio signals separately from clock signals and other control signals, are converted into I2S signals in the FA.KA 1. Using this method enables the revolutionary concept of CHRONAL TECHNOLOGIE to be implemented consistently for all audio sources. The FA.KA 1 also functions as a remote control for the digital sources and as an amplifier using a tablet-PC and displays the volume.

The casings of FÖRSTER AUDIOTECHNIK digital devices are shaped out of a solid piece of aluminium and make a positive impression with their top-class craftmanship. In order to completely decouple the casings mechanically from the substrates, three precision metal components made from polished stainless steel are inserted into each casing on which the devices, which are cushioned with rubber rings, almost "hover".

The result of this unique technology and perfect craftmanship is the best possible audio experience that simply can’t be beaten, with technology becoming art.

A German design patent has been applied for our FA.KA 1 under the official file number 40 2013 200 064.7 .












Our high-end two-channel digital amplifier FA.DV 2 can be combined with other digital components and our (analogue) speakers to offer the best possible musical experience using CHRONAL TECHNOLOGIE. The FA.DV 2 is an extremely high-performance digital amplifier with two separate amplification stages for providing a separate power supply to the subwoofer and the midrange speakers as well as tweeters, respectively.

In the context of CHRONAL TECHNOLOGIE, we have developed a unique system for the FA.DV 2 that can be used to transmit digital signals including time and clock information across numerous parallel optical cables without there being any loss, disturbance and jitters. The purely optical mode of transmission also covers large distances of several hundred metres.

The digital amplifier created with a minimalist and timeless design is positioned laterally at the loudspeaker adjacent to its rear edge in order to ensure efficient energy transmission, and is connected to the respective speaker via the FA-BRÜCKE that makes the conventional speaker cables redundant and acts as a replacement for them. A potential alternative method to this is creating a connection using our FA.AK 2 speaker cable.

In combination with the other FA digital components, the FA.DV 2 uses CHRONAL TECHNOLOGIE to provide a pure, clear and particularly voluminous sound that at the same time reproduces all the "warm" and emotional nuances of music without adding or taking anything away. Enjoy music exactly how the artist created and the technician perpetuated it in the recording.

The FA.DV 2 digital amplifier is in the planning stage and is expected to go into production from the start of 2014.












The unique and innovative development of the FA.DV 1 digital amplifier from FÖRSTER AUDIOTECHNIK is promoted by the Free State of Bavaria and with good cause. As a high-end digital amplifier, it can be combined with other digital components and our (analogue) speakers to offer the best possible musical experience using CHRONAL TECHNOLOGIE. The FA.DV 1 is an extremely high-performance single-channel digital amplifier. It contains a single powerful amplification stage for supplying power throughout the speaker.

The Audiorechner FA.AR 1, which we developed ourselves, can be operated easily and intuitively by a tablet remote control, just like a CD player. Its specially programmed RAM player software takes the digital data directly from the hard disk, a USB flash drive, or the network and transfers them at 100% to the RAM, from where they are then reproduced in real time. The FA.AR 1 uses a Linux-command line-OS with real-time kernel as operating system. Communication is completely jitter-free – for an extraordinary music experience without inaccuracies and deferrals; for an absolutely precise, spatial and natural sound that enchants all senses and triggers emotions.

One exceptional feature is the specially developed, error-free interface at which the data with the corresponding time and tact information are being transmitted over several parallel optical links. All in line with CHRONAL TECHNOLOGIE, with which FÖRSTER AUDIOTECHNIK vouches for a uniquely flawless reproduction quality.

The FA.DS 1 is our SACD transport which we developed according to the high standards of CHRONAL TECHNOLOGIE. It transmits digital data read from a CD or SACD to the digital amplifier. The interface usually used in this process is highly susceptible to jitter, which impairs the sound experience.

But not with the interface specially developed by FÖRSTER AUDIOTECHNIK, throughwhich FA.DS 1 communicates: It is based on several parallel optic fibres, which transport the digital audio data separately from the time and tact data completely without errors. The result is a perfectly natural, time-coherent, clear and spatial reproduction of music . You will hear the difference!

Our fibre optics cable FA.AK 1 transmits data without any losses thanks to the high frequency of light. In the audio sector optical fibres are used in connection with toslink interfaces, which, unlike the high-quality optical fibre cables we use (in connection with I2S interfaces), do not exhaust the technology of optical fibres in connection with I2S interfaces.

At FÖRSTER AUDIOTECHNIK we use optic fibre cables with four bundled optical fibres for interference-free separate transmission of data-, time- and interface-related control information.

By the way, the data connections between the earth’s continents also consist of optic fibres because they can transmit signals over great distances with an extremely low rate of losses and interferences.
