Signal processing
The Bit One HD features a powerful Sharc series DSP ADSP-
21489 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 conguration allows for the use of digital FIR networks
to reach new milestones for in-car listening experience. In case
of interfacing with an OEM system through the MASTER inputs,
following the conversion from analog to digital, the bit One HD
provides the ability to:
1. (De-Ta) automatically detect time alignments, often found
in multi-amplied OEM systems, synchronizing input channels
(delay compensation) before reconstructing the signal;
2. sum up the signals coming from multi-amplied emission
fronts, to automatically reconstruct a full-bandwidth stereo
signal;
3. (De-Eq) flatten the frequency response using the FIR type 5
parametric poles input equalizer, to obtain a distortion-free
signal even from the most complex OEM systems.
After reconstructing the emission fronts and when using the S/PDIF
digital inputs or the AUX input, the bit One HD, thanks to the new
SW interface, provides the ability to:
4. customize the entire audio system frequency response using
the 5 parametric poles FIR type main equalizer, to satisfy any
music genre;
5. manage the subs and woofers channels equalization, thanks
to the Bass Boost function selectable via DRC MP;
6. improve the listening with the Dynamic Equalization function
acting on the variation of the frequency response when the
volume changes;
7. be ltered with a Linkwitz, Butterworth or Bessel crossover
alignment, with adjustable slopes between 6 and 48 dB/Oct.,
at the useful cut-off frequencies within the audio bandwidth,
for high-pass, low-pass and band-pass lter types with
asymmetrical slopes;
8. time-delay each output channel up to 22 milliseconds,
corresponding to 760 cm speaker virtual movement, with
a maximum resolution of 0.01 ms. In keeping with the Audison
tradition, the software simplies the time delays set up through
the time/distance double notation. The delay can be set up for
each channel (loudspeaker) or for a group of loudspeakers
within the same emission front;
9. correct the frequency response in the car compartment using
the 11 poles parametric output equalizer, within a wide range
(±12 dB), setting the Q factor and the cut-off frequency for
each channel at very high resolution and precision;
10. adjust the output levels of each channel to better balance the
system overall response;
