www.audison.eu In-Car Studio Master Quality After revolutionizing the car audio world with the bit One digital processor, thanks to continuous research in the digital domain, Audison now introduces the bit One HD, capable of processing audio signals with 24-bit/96 kHz resolution.
www.audison.eu New Software EISA, European Imaging and Sound Association, has nominated the Audison bit One HD EUROPEAN IN-CAR PROCESSOR 2016 – 2017. The EISA Awards jury's reason in giving this prize is as follows: “With its bit One HD Audison opens up a new era in DSP, using the most powerful chipset to maintain the throughput of high-resolution audio at 96kHz/24-bit for optimum quality.
www.audison.eu Delays Compensation and Input De-Equalization for OEM Systems The bit One HD is equipped with a guided configuration routine which automatically synchronizes the input audio channels, which are often time-delayed from the OEM source or amplifier, prior to the signals summing. A De-equalization of the OEM system frequency response is then performed, featuring linear-phase FIR filters, to obtain an unparalleled reconstruction of the original signal without altering the phase response.
www.audison.eu FIR and IIR filters FIR filters allow for an improved sound quality. Crossovers and equalizers do not cause phase variations on the audio bandwidth, acting as if they were ideal systems. This processing, with an elevated computation cost, is made possible thanks to the DSP reference performance. The IIR filters, deriving from the analog theory, simulate the electric behavior of a traditional crossover, introducing a phase distortion altering the system frequency response.

www.audison.eu OEM Integration The bit One HD further improves its integration level with OEM head units, offering full support to the management of the car priority signals such as parking sensor alerts, GPS messages, phone and vocal commands whilst music is played through an auxiliary source such as the bit Play HD. The new functions listed below further enhance the processor’s control capabilities.
www.audison.eu DRC MP - Digital Remote Control Multimedia Play The DRC MP supplied with the bit One HD features a reduced size and a total black look with possibility of customizing the RGB light of the volume control as well as the keys. A Joystick has been added to the volume knob, providing the ability to intuitively browse the menu, adjust the display colour and brightness and also control a bit Play HD that may be connected to the processor.
www.audison.eu Signal processing The Bit One HD features a powerful Sharc series DSP ADSP21489 Analog Device which thanks to the 32 bit floating-point arithmetic, optimized to process high performance audio, is capable of elaborating 2.7 GFLOPS at 450 MHz. Such a powerful hardware configuration allows for the use of digital FIR networks to reach new milestones for in-car listening experience.
www.audison.eu bit Drive Technology By registering the bit One HD to the bit Drive portal (http://bitdrive.it) the processor will be always up-to-date: the PC software checks the availability of upgrades online and the user is constantly informed about the new functions available. In this way it will be a long-lasting investment.
