While installation and sound deadening will eliminate some of these issues, it is necessary to use dedicated processors and digital interfaces to correct the fundamental issues.

For those who want the most out of their car audio system, a digital signal processor can help. After some slight adjustments, your system will sound like it has been professionally tuned and optimised.

There have been rumours that if your speakers are good enough, you won't require a processor. Unfortunately, this isn't the case because it's the environment that creates the need for a processor, not the speakers.

Digital signal processors (DSP)

Most Original Equipment Manufacturer (OEM) factory fitted stereo systems are underwhelming in terms of quality sound. Well, they may have convenience features like iPod inputs, Bluetooth hands-free and steering wheel controls but they lack the ability to fine tune audio performance as well as add extra amplification.

Most OEM stereos are also designed to compensate for low quality speakers, which is accomplished by artificially manipulating the frequency profile.

When inferior original equipment speakers are replaced with high quality aftermarket units, this manipulation is often very easy to pick up on and if an amp is also installed, the problem will only get worse.

That's where a DSP can come to the rescue. There are a number of uses for DSPs, but one of the most remarkable is to fix problems that have been noticed with OEM stereos.

The DSP sits between the head unit and the amp, and it can literally undo the factory unit's problems. Some DSPs even have custom profiles that can be downloaded from the Internet, which will automatically fix the pre-processing issue and improve the overall listening experience by finetuning the head unit to suit the interior of the specific vehicle.

Audison has released a number of digital components that make it not only easy to get great sound from factory sound systems, but also allow for a complete digital connection from processors to amplifiers.

One of them is the Audison bit Ten - a DSP that will be equally at home in a modest system or a full-blown competition car audio system.

The bit Ten is a multi-function DSP featuring analogue input, capable of transforming an OEM or aftermarket system into a high performance system.

This processor comes with a 32 bit, 147 MHz clock speed Cirrus Logic DSP. It is a special DSP, ensuring high integration, where the main processing functions are implemented in optimised and pre-configured blocks, providing the ability to reduce the processing resources, thus ensuring top level performance.

The architecture is completed with 24 bit analogue to digital (A/D) and digital to analogue (D/A) converters, as well as a powerful microcontroller to manage, supervise and connect the system to a computer.

During the installation phase, where conversion of the analogue signal into a digital one is done, the bit Ten automatically reconstructs a digital full-bandwidth stereo signal and de-equalises the frequency response and, if necessary, reconstructs the central and subwoofer channels.

Users can also configure the output mode of each channel relative to the installed system.

bit Ten and its advantages

Audison truly sets the level when it comes to getting great sound quality in your vehicle, and with the bit Ten, they have designed a product that allows anybody to upgrade their system, no matter what vehicle they have.

All of the operations on the bit Ten, from setting the parameters of each input single channel, setting the delays according to the listening position to adjusting crossovers and equalisers for each of the five output channels can be managed with or without a computer.

The other great advantage of the bit Ten is that you can retain your factory fitted head unit, which is often heavily integrated with other climate and vehicle controls. The bit Ten uses advanced processors to digitally correct factory speaker placement and frequency response, providing a great one-stop solution with minimal component replacement.

The bit Ten boasts a modern and flexible platform, making it possible to stay current with technological evolution.The firmware, based upon Flash memory, can be updated at any time without having to disassemble the device from the system.

And to make things even better, the bit Ten has a built in AUX input, allowing you to plug in an MP3 player, or any other audio device, so if your car doesn't have an input, the bit Ten will take care of it. The bit Ten also allows for a hands-free kit and offers an audio mute as standard as well.

Having amazing sound really has just got easy, thanks to this little box of tricks.

Why Audison?

With 34 years of experience in the audio industry, Audison is a renowned name in the audio industry.

Since 1979, the founders of Audison have fuelled a long lasting passion for high quality sound, continuing to design and build tools which can produce the perfect sound.

In addition, they design and select the materials, experiment and listen to the results time and time again, allowing only their emotions to let them recognise when the product was complete.

Since its inception, Audison presents its products to the market only after they have fully met the requirements of their creators to ensure that the highest quality is delivered.

More impressively, Audison has many awards and accolades to its name such as the European Imaging and Sound Association (EISA) Award, the Innovations Design and Engineering Award and many others.
