News: Audison Bit-Ten Processor Preview

While we've been unable to obtain any official press releases or information on the new processor, we have managed to obtain a few images and some preliminary information from other sources. There will be two processors, one known as the 'Bit-Ten' and a second processor known as 'Bit-Ten D'.

Connect, Customise, Control

"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."

bit Ten and bit Ten D - Technology

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 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.

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 ofall 8 channels directly at the amplifier.


While not confirmed, we're also told that Audison will be releasing a new head unit (perhaps designed by Clarion?) designed to connect via digital means directly to a 'Bit' processor, which of course as we know can then interface in the digital domain through to appropriate Audison amplifiers.

Pricing and availability has not been provided by the Australian Audison Distributor as yet, however we are sure that once this information is available we will be provided with this.
