6. Source De-equalization/ Phase Analysis
Operation not mandatory, but necessary for equalized OEM sources.The de-equalization process performs an analysis of the electrical frequency response comingfrom the different channels of the OEM source, automatically applying an equalization contrary to the original one, thus generating a linear signal, much more suitable to drive high quality audio systems.Regardless of the input channels used, the de-equalization will be performed for each functional group.
E.g.: even though Front Left Full and Front Right Full inputs are used, the software will perform the de-equalization also on Rear, Center and Subwoofer inputs as the
processor will have to use the signals identied as
Front to possibly also manage the Rear, Center and Subwoofer outputs.

"PASS THROUGH" allows the interface in direct
conguration between inputs and outputs.
Moreover, during the guided procedure it allows to divide the emission front in order to increase the number of existing ways per
front. The peculiarity of this conguration
is that it does not provide any equalization, correction of time delays, phase variations and channel sums, allowing subsequently only to intervene on time and phase alignment equalization for the Master input. When using the other auxiliary inputs (AUX, Optical 1/2) it is also possible to separate the Master setup by creating one that performs better than the limits set by the OEM system.
Remark: if the Master conguration features
Rear Surround channels, during the selection of the auxiliary inputs these will not be available. The procedure must be performed by selecting which memory to assign the Master Pass-Through input from the start.

The bit One HD Virtuoso manages the system setup working on Preset A by default; however, it also offers the possibility to store and recall eight Presets (A, B, C, D,E,F,G,H).
Pressing the MEMORY button on the main menu you can access the different functions you can perform on the featured presets.
The following functions are available:
- Load All Presets: it loads all the memories (A/B/C/D/E/F/G/H)
from a le previously saved (.prs format);
- Save All Presets: it saves all the memories (A/B/C/D/E/F/G/H)
in a le that can be recalled (.prs format);
- Load Current Preset: it loads a memory previously saved (.pro format) by placing it on the memory you are operating on;
- Save Current Preset: it saves the memory you are operating
on in a le that can be recalled (.pro format);
- Copy Preset From: it provides the ability to copy the content of one memory into another memory;
- Current Preset Default: it restores the crossover and equalization default values, that would be suggested at the end of the set up procedure;
- Enable Memory Overall: it enables the Overall function which recalls a memory previously saved (see following point), optimized for a perfect listening from all positions within the car compartment. This function can be activated through the terminal, setting the Overall Sel cable to +12V
(see section 8.3.4);
- Select Memory Overall: it congures an existing memory as “Overall”. If an existing memory has been congured with time
delays, these will be reset and the Car Central will be set up as the listening position
(see section 4.3.5). At a later stage, the
settings related to this “Overall” memory can be modied.
The following data will be stored into the presets:
- the lter settings for each channel;
- the time delay settings for each channel;
- the equalization settings for each output channel;
- the Main EQ settings
(see section 8.9.2);
- the Dynamic EQ settings/activation (see section 8.12.3);
- the Bass Boost settings/activation (see section 8.12.4);
- the output levels of each channel;
- listening points markers.
We recommend that you copy the parameters entered in the preset you are using into the presets that are not being used. The presets can be recalled through the DRC MP. If some presets are not stored, they will store the default settings.
Pass through
In Pass through mode there is only one memory, assigned in
the "I / O conguration Wizard" phase, to the Master input.
So when the Master input is selected will be available only one memory, and it will not be possible to copy other memories on it. The remaining memories and related functions will be available at the input change.

Difference between IIR and FIR lters.

IIR digital lters faithfully simulate analog lters (active or passive), approximating phase
vs IIR FILTER
and frequency behavior. Like their analog equivalents, they are affected by unavoidable phase rotations at the cut-off frequency, which are different based on the type of curve used (Butterworth, Linkwitz, Bessel), however still perceived when listening. In practice, for instance, a fourth-order low-
pass IIR lter (24 dB / Oct) at 200 Hz cut-off, plus a high-pass symmetric lter, results in a
phase rotation ranging from 0 to -360 degrees along the whole audio spectrum. This phase alteration affects the perception of the sound image, which highlights inaccuracies in terms of coherence and stability.
Think of a 3-way system where the door-mounted 18 cm woofer is 400 Hz crossed with the middle-range, installed on the a-pillar next to a tweeter, itself crossed with the middle-range
at 5.000 Hz, using crossovers with IIR lters.
The system phase alteration reduces the focus of the instruments on the virtual stage. For this reason, a number of audio enthusiasts prefer to adopt 2-way systems with a woofer

and tweeter crossing at 2.500 Hz with a slope of 6 dB / Oct, so as to limit phase rotations as much as possible. This solution, however, presents a number of
signicant disadvantages, mainly due to increased distortion and lower tweeter power. With a slope of only 6
dB / Oct., the music signal around the cut-off frequency is simultaneously generated by tweeters and woofers to a considerable extent. Since a tweeter and a woofer have very different electro-acoustic parameters, the sum of the two emissions does not produce clear output signals, which results in less clarity in the reproduction of musical transients.
Improved acoustic quality with the use of crossover lters and FIR equalizers.
The use of FIR lters guarantees an important result: the phase behaviour is linear, free from rotations or indecisions. This also makes the use of lters with a very high slope (up to 48 dB / Oct) possible, without altering the phase response. Such a high slope for the lter enables the midrange and tweeters mounted on the a-pillar
to work at lower frequencies without any issues with power handling, thus raising the emission front.
Therefore thanks to the FIR lters the advantages of three or multiple-way systems are completely exploited taking in-car listening experience to a different level. When listening, a system that uses FIR lters provides great
clarity in transients reproduction, such as the acoustic piano hammer strikes or the drums. The stereophonic
image is deeper and denite. Instruments in the virtual stage are more focused and seem to have more space
between them. Even the intervention of any equalizer over the frequency response, when available in FIR technology, does not modify the audio signal phase, allowing more precise and detailed corrections without conditioning the audio quality.

8.7.2 SET DISTANCE AND DELAY

Two modes are available for the set up of the bit One HD’s time delays:
- Basic Mode. The system time delays can be displayed by selecting the Channel Map loudspeaker from the main software screen. Then enter the distances (cm/inch) from the
listening point, and the related “ne set” (ms).
- Extended Pop Up Mode, by selecting the icon the extended menu for the set up of time delays will appear. This operating mode, as well as allowing a faster and easier data entry, will provide different views of the time delays according to the listening point, the farthest speaker, depending on the distance (cm/inch) or time (ms).

Preliminary remarks
Sound moves through the air at a speed of 343 mt/sec (1.125 ft/sec) and at the temperature of 20°C (68°F). If you know the distance from the sound emission point, you can then calculate the time sound takes to get to the listener’s ear. By default the bit One HD enables the entry/automatic calculation of time delays by entering the simple measurements between the listening point and the speakers by selecting the option “From Listening Point cm/inch”. It is however possible to enter the same time delays with respect to the listening point by entering the time value (ms-milliseconds), selecting the option “From Listening Point ms". If instead of the distance from the emission point only the distance between the loudspeakers with respect to the farthest emission point is available, it is possible, by selecting the option “From Farthest Speaker cm/inch, once the farthest
speaker is selected, to enter distances from the other speakers, and then ne-tune the remaining speakers of the system.
However, it is possible to enter the same time delays with respect to the farthest speaker by entering the time value (ms-milliseconds), selecting the option “From Farthest Speakers ms". Switching between the 4 time delay entry modes is automatic, the software will automatically convert the values displayed on the Channel Map.
FINE SET AND PHASE DELAY.
The delay assignment according to the distance calculation is theoretical. That is, small variations need to be applied due to small errors in distance measurement, due to the resonance inside the car compartment and, mainly, due to the speaker phase problem. Two speakers reproducing two areas of frequency one close to the other (ex. Woofer and Midrange), in their crossing area will simultaneously reproduce, at attenuated level, the same frequencies. Due to the different nature of the speakers, they will show a difference in phase that, for a short frequency interval, works like a time delay.
By acting on the “ne set” you can partly also correct problems of Phase Delay. By acting on the “ne set” you can change the automatically set time delay. The delay that is varied adds up to (+
x.xx) or is deducted from (- x.xx) the value of the delay shown in the “Delay / default” window, which does not change
the assigned value which is the one automatically assigned. Assigning a positive value ( + x.xx) with the “ne delay”
means increasing the delay of that speaker and therefore moving it away from the listening point. Likewise, assigning a negative value (- x.xx) means decreasing the speaker’s delay and therefore moving it closer to the listening point.
If you try and give a negative value to the farthest speaker, an alert message will be displayed. By acting on “ne set”,
the word “fds” will light up on the corresponding channel of the “Channel Map”, to inform the user about the entry on the highlighted channels.

alter the signal phase behaviour with signicant
effects on audio quality. A heavily equalized signal is characterized by an unclear stereo image and
lack of transients denition. Audiophiles often
classify this feeling as a veil that blurs the musical message and deprives it of the necessary emotion.
The use of FIR lters guarantees an important
result: the phase behaviour is linear, free from rotations or indecisions. This also makes the use
of lters with a very high slope (up to 48 dB / Oct)
possible, without altering the phase response. Such
a high slope for the lter enables the midrange
and tweeters mounted on the a-pillar to work at lower frequencies without any issues with power handling, thus raising the emission front. Therefore
thanks to the FIR lters the advantages of three
or multiple-way systems are completely exploited taking in-car listening experience to a different
level. When listening, a system that uses FIR lters
provides great clarity in transients reproduction, such as the acoustic piano hammer strikes or the

denite. Instruments in the virtual stage are more focused and seem to have more space between them. Even the
intervention of any equalizer over the frequency response, when available in FIR technology, does not modify the audio signal phase, allowing more precise and detailed corrections without conditioning the audio quality.
The equalizer works for functional groups and therefore we will have:
- an equalizer for the Front Left Channel;
- an equalizer for the Front Right Channel;
- an equalizer for the Rear Left Channel;
- an equalizer for the Rear Right Channel;
- an equalizer for the Center;

Remark: if the installation includes a mono Subwoofer, the
sensitivity of its dedicated amplier needs to be increased by +3 dB compared to rest of the ampliers (see the “Ampliers
Sensitivity” diagram). This empirical method considers many aspects and will provide an improved adjustment capability of

the “Subwoofer Level.
Important Remark:
the output level adjustment (2) affects the system signal / noise ratio (whistle / background
hiss). We recommend that you always set the bit One output at high level and the ampliers’ sensitivity at low
level, so the ampliers will be less sensitive to background noises/hisses. An excessive output level causes the
clipping led lights to turn on (1), especially if equalizations with high gain are applied. Therefore we recommend that you proceed as follows:
a) Adjust the ampliers sensitivity level to the minimum value (3-4V RMS). b) Balance the emission level of the system channels by moving the sliders (2) paying attention to maintain a
centered mid level at around -20 dB. Turn the output volume to an acceptable listening volume level. c) Set the desired output equalizations
(see sec. 8.9).
d) Insert a CD playing a highly dynamic track. e) Select the “Link” function (5), move the slider and increase the output channels level until one of the “clipping”
led lights turns on (1); move the slider back of at least 2-3 dB (check the value on one of the displays (3)).
f) Increase the “Master Volume” (6) up to the maximum undistorted level taking it close to “0” dB. g) In case the signal is highly distorted with the “Master Volume” at “0” dB, the output levels (2) will need to be
decreased or enable the “Limiter” function. If, on the contrary, no distortion occurs, the ampliers’ sensitivity will have to be increased until the rst distortion symptoms appear: by doing this, you will make the most of
all the available power.
Remark: this procedure leads the user to calibrate the system at “zero dB undistorted”. This is not always the best
solution, since, if you listen to a track that has been recorded at a lower level or with lower dynamics than the track used for the setup, a loss in dynamics may occur. So a good compromise needs to be found, depending on the listener preferences.

channels selected in the menu “Trace Curve”. If a “Phase Analysis” was performed
(see xxxxxx), two curves will be displayed. The
Blue curve refers to the trend of the selected
fronts, where the presence of All-Pass lters
can be shown, provided by one or more holes in the frequency domain, while the orange color refers to the fronts compensation via
All-Pass lters. If the Phase Analysis was not performed, only the orange curve resulting from the modications
made via All-Pass adjustment will be displayed.
Phase ON/OFF By clicking on the Phase on/off key, it is
possible to enable or disable the correction of the phase applied to the Head Unit connected to the bit One HD Virtuoso. The activation is successful when the led light becomes red.
Restore Phase Alignm suggestions: If an “AUTOMATIC MASTER DE-EQ / PHASE
Analysis” was performed and new valued are then edited, it will be possible to restore the phase compensation values suggested by the software (see sec. 7.2.2.6).

3. Dynamic EQ: the sound of an audio system may very according to the reproduction volume. At low volume,
the noises coming from outside the vehicle and the especially insulated acoustic within the car compartment contribute to limit (especially in low frequency) the system’s performance. Generally during calibration you need to consider that the adjustments performed with low level volume may change relentlessly when the volume will be increased.
The Dynamic Equalization improves the listening actively operating on the variation of the frequency response as a consequence to the volume change. The Wizard will suggest a series of windows to set up the equalization to be applied to the general frequency response. The bit One HD Virtuoso will automatically perform a gradual data interpolation, following the signal level and therefore acting according to the system volume. Two operating modes are available. To use this function click on the button to the left of the menu until the orange led lights up. To disable the function click again on the button until the orange led turns off.
To set up the dynamic equalizer click on the button to the right of the menu and proceed as follows:
EASY MODE
Insert a CD in the source and play a reference track. Select the Easy operating mode. A semi-automatic procedure will start. Move the Volume slider setting the low volume listening reference level. After adjusting the slider, select START.
Move the EQ slider to set up the low volume response equalization until the desired sound is achieved. In this case the equalization curve which applied is pre-set. When reaching the desired setting select SAVE. At this point the reference curve for low volume listening will be applied.

USER'S MANUAL
The semi-automatic procedure continues requesting the set up of the high volume listening reference level. Move the Volume slider to the desired level. After adjusting the slider, select START.
Move the EQ slider to set up the high volume response equalization until the desired
sound is achieved. After nding the right
adjustment select SAVE. At this point the reference curve for high volume listening will be applied.
