Informácie o produkte Audison bit Ten

CONNECT, CUSTOMIZE, CONTROL
     How many times have we met the limits of OEM or after market integration, expandability or the overall sound quality of our mobile audio system upgrades? Audison bit is the solution: multi-function digital processors capable of interfacing with any analog and/or digital source, transforming ordinary “audio” into a high-performance integrated system.
     In 2009 Audison introduces bit one, the first Signal Interface Processor conceived and built following the Audison philosophy: to satisfy a genuine passion for Sound, even with based on an OEM source.
     Quickly, the bit one became a world-wide reference amongst audio processors. The experience that our team acquired allowed us to expand our family of processors, making available the possibility of realizing higher performance systems to a wider audience. bit Ten originates directly from its predecessor, the bit one for signal management, basic functions and PC software. The bit Ten D version can also manage a digital input signal from the head unit, outputting a digital signal to an amplifier(s) featuring AD Link connection.
     All bit processors feature a powerful DSP (Digital Signal Processor) managed by a simple and intuitive computer software, which ensures a wide array of adjustments to improve the signal through each phase of its path; from input to output.
     A revolutionary technology; making your dream for acoustic perfection in your vehicle a reality!


CONNECT
Connectivity without limits
     Acoustic reproduction begins with traditional sources such as radio, then Compact Disc and now moving on to the use of new devices like MP3 players, streaming mobile phones and other multimedia devices.The bit processors provide the ability to take advantage of these technologies by bringing them all together, making the most of the musical performance.
     Input channels for different signal typologies, along with analog and digital output channels ensure vast expandability of any audio system.

CUSTOMIZE
Listening Freedom
     The bit project was born with the aim of creating a perfect acoustical environment in every vehicle, customizable for every listening position, letting you experience true mobile bliss.
     Today’s new vehicles are equipped with audio systems which offer very little, if any, upgrade opportunities. The most technologically advanced factory systems feature proprietary functions that are in most cases essential to the vehicle operation, but their sound is generally unsatisfactory.
     The bit processors are designed and developed to control every parameter of the reproduction, providing the ability to regenerate and customize the system’s sound to reproduce even the finest details.
     The concept of complete listening freedom becomes real.

CONTROL
The digital domain
     The unlimited calculation capability of the bit processors DSP (Digital Signal Processor) is combined with an extremely user-friendly interface. Specifically designed for audio applications, the DSP processes the signal in the digital domain: the management and control of the acoustic reproduction are further improved by the accuracy and configurability of the digital system.

bit Ten & bit Ten D - Technology
Signal processing
     bit Ten features 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 optimized and pre-configured blocks, providing the ability to reduce the processing resources, ensuring top level performance. The architecture is completed with 24 bit A/D and D/A converters as well as a powerful microcontroller to manage, supervise and connect the system to the PC.
     The audio signal follows a complex path, controlled by software managing the bit Ten.
     Following the conversion from analog to digital, or otherwise starting in the digital domain using one of the S/PDIF digital inputs, the bit Ten provides the ability to:
1. automatically reconstruct a linear full-bandwidth stereo signal;
2. de-equalize the frequency response, to “correct” any possible equalization present in the OEM sources. This operation can be initiated through a simple push button switch found on the device, negating the need for a PC connection;
3. provide a 31 band equalizer to contour the input frequency response;
4. reconstruct the signal, in the case that the system requires a centre channel or subwoofer when the corresponding signals are not available as input channels

     The user can configure the output mode of each channel relative to the installed system, and for each channel can:
1. be activated, de-activated or phase inverted;
2. be filtered with a Linkwitz or Butterworth crossover alignment, with adjustable slopes (6- 24 dB/Oct.), with 20 to 20,000 Hz cut-off frequencies, in Full-range, Hi-Pass, Lo-Pass and separately configurable slopes and frequencies on each side of a Band-Pass filter;
3. be contoured with 31 bands of 1/3 octave equalization, within a 20-20000 Hz , +/- 12 dB range with 128 step resolution;
4. be acoustically time aligned with the other channels with up to 15 milliseconds delay, in 0.02 ms steps, corresponding to a 510 cm virtual “movement” of the loudspeaker. The user can adjust the initial delay settings by following a guided on-screen procedure for a consistent reconstruction of the sound stage. A manual adjustment function is available for “fine tuning” of the delay;
5. adjust its output level to further tune the system’s overall response.

SOFTWARE
     For total control of the system parameters, a software to be installed on the PC is provided. Developed according to specific criteria required by the Car Audio industry, it facilitates direct access to the innumerable signal treatment functions available; providing immediate results, as well as extreme operational accuracy.
     Setting the parameters of each input single channel, setting the delays according to the listening position, adjusting crossovers and equalizers for each output channel; all of these operations can be managed by the PC.
The Windows-based (XP, Vista and 7) software can be used in Standard of Expert modes. The Standard mode guarantees straightforward and simplified system management achieving great results with little effort: a guided set-up procedure, according to the parameters assigned to the outputs, assists the user in setting up the crossovers and equalization enabling the tuning of any system in just a few “clicks”.
     With the Expert mode, the software provides the ability to freely access all the parameters for a "fully-custom" tuning experience.
     The software features a Context-sensitive Help, that the user can activate, opening in a dynamic help window displaying detailed description of its main functions.
     In addition to that, it can manage multilingual context: the user can select the language and the change will be applied to the drop-down menus as well as the Context Help messages. The number of available languages will increase: once updates are available, they will be downloadable from the Audison website.


SYSTEM UPGRADE
     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.
     The software enables the user to check on available on-line updates (http://update.audison.eu) guiding the user through all of the upgrade phases. In addition to that, the user can manually force the update and proceed with a safe installation which can be retrieved even in case the update fails due to external accidental causes.

BIT TEN - ARCHITECTURE
Innovative Design
     bit Ten inherits from bit one a minimal and compact design. Like with the bit one, the perfection of the design and proportions of the new processor equal the flawless layout of its internal technology, easing the installation.
     The DRC provides direct interface between the user and the device. Through an ergonomic knob, adjustments can be made rapidly and accurately. A liquid crystal back-lit display provides visual elements to the user. The compact size and the dark grey aluminium finish allow the DRC to seamlessly integrate into any dash layout; adding a touch of originality and technology.


Universal inputs
     bit Ten provides 7 signal inputs with different connection typologies: four high-level inputs, also accepting low-level pre-amplified signals; a stereo auxiliary input; a standard Remote IN and a high-level (PHONE IN) “momentary audio interrupt” input for use with devices such as cellular phone hands-free kits that provide a "Mute" function.
The bit Ten D version also features an optical digital input, selectable from the DRC, minimizing interference and degradations of the signal found in traditional analog interconnects, also by-passing the A/D conversion phases of analog signals.
     Thanks to the on-screen instructions provided by the software during the set-up, bit Ten can automatically sum multiple filtered channels (for instance, woofer plus tweeter) and then “flatten” the equalized response curve of the OEM source. It can also reconstruct a centre, rear and/or subwoofer outputs with a simple stereo input. By reading the appropriate  track on the provided test disc (CD), the DSP reconstructs a full-bandwidth signal, rectifying its frequency response, providing a “full bandwidth” signal ready for further processing.

Outputs
     bit Ten provides 5 PRE OUT analog outputs. Each output channel features a 31 band equalizer, a 66 step electronic crossover with selectable Linkwitz-Riley or Butterworth alignment with selectable 6 - 24 dB adjustable slopes and digital time delay functions.
     Through the AD Link connector, bit Ten D provides the ability to increase the number of outputs channels to 8, all in a digital format. With the use of a CAT 5.S cable terminated with a shielded RJ45 connector (as used with LAN connections), the digital signal is transmitted to amplifiers equipped with this feature (such as found on the Audison Thesis TH series and/or the new Audison Voce amplifiers, coming soon).
     It is possible to use the two different output typologies (analog and digital) simultaneously for a maximum of 8 outputs total, as the software provides the ability to direct the audio signal to each output channel independently. AC Link is dedicated to the “remote control” of the system. The system is comprised of one connector for the provided DRC (Digital Remote Control) and one for the amplifiers present in the system. By connecting the AC Link output to the amplifiers, it is possible to control the volume of all 8 channels directly at the amplifier.

DRC – Digital Remote Control
     Digital Remote Control permits the control of the main system without the use of a PC.
     Installed in an ergonomic position within the dashboard of the car, the user can: choose between two “tuning” configurations pre-sets created and saved using the bit Ten software; select the source from the master, auxiliary and optical digital inputs (the digital input only with the bit Ten D, which comes packaged with the DRC); adjust main system functions (volume, balance, fader and subwoofer volume); identify the proper position of the sources output level set while tuning the bit Ten as well as adjust the display brightness for ledgeability and to reduce glare during night driving.
