ADVANCED MANUAL / bit Ten / 1/2
1. PRODUCT DESCRIPTION / PRECAUTIONARY NOTES
The bit Ten is a digital signal processor essential to maximize the acoustic performance of your car audio system.
It consists of a 32-bit DSP processor and 24-bit AD and DA converters.
It can connect to any factory system, even in vehicles featuring an integrated audio processor, since, thanks to the
de-equalization function, the bit Ten will send back a linear signal.
It features 7 signal inputs: 4 Hi-Level, 1 Aux Stereo, 1 Phone and provides 5 PRE OUT analog outputs.
Each output channel has a 31-band equalizer available. It also features a 66-frequency electronic crossover as well as
BUTTERWORTH or LINKWITZ filters with 6-24 dB slopes and a digital time delay line. The user can select adjustments
that allow him or her to interact with the bit Ten through a remote control device called DRC.
WARNING:1- a PC provided with Windows XP, Windows Vista or Windows 7 operating system, 1.5 GHz minimum
processor speed, 1 GB RAM minimum memory and a graphics card with a minimum resolution
of 1024 x 600 pixels are required to install the software and setup the bit Ten.
2- Before connecting your bit Ten, carefully read this manual. Improper connections may cause damage to
the bit Ten or to the speakers in the car audio system.

6. HOW TO SETUP THE bit Ten WITHOUT A PC
The bit Ten can be used without a PC.
In this case, you can mainly use only the DE-EQ (de-equalization) function to eliminate any pre-existing equalization in
the audio system, usually installed as standard by the car manufacturer.
The device will store the following default settings:
1. Front and Rear stereo broadband inputs;
2. Phone input with automatic switching when a call is received;
3. AUX input that can be selected if the DRC is available;
4. Front and Rear stereo broadband outputs;
5. Mono Lo-pass filtered SUB output at 150Hz / 12dB Oct.
WARNING: All outputs have no equalization or time delays. If you wish to use the Rear output,
you will have to connect the head unit Rear outputs to the bit Ten input.
6.1 HOW TO CALIBRATE THE MASTER FRONT-REAR INPUT SENSITIVITY
1. Connect the head unit speaker outputs to the bit Ten high-level input (see 4.2).
Before turning on the system, make sure the amplifiers RCA plugs are disconnected from the bit Ten to
avoid speaker damage during the calibration procedure.
The input calibration procedure must be performed with the ignition turned on. In this case, the car voltage is about
14.0 Volts. The head unit will provide an undistorted output signal at higher volume.
2. Make sure that the IN Level knobs for the inputs used (L / R Front, L / R Rear, Phone, Aux IN L-R) are set to minimum
sensitivity as in the figure (position -).
3. Turn on the device and play track 1 of the CD supplied with the bit Ten.
• Set all tone controls to zero (flat).
• Set balance and fader to center.
• Adjust the head unit volume to the maximum undistorted output level.
• If the head unit provides an adjustable equalizer, make sure that the controls are set to zero (flat).
WARNING: the head unit level must be elevated to the maximum undistorted level. If the head unit distortion level
can not be tested in advance, bring the volume to approximately 80% of its maximum. If the head unit output
level is set too low, the device will produce ground noise (hissing sound) when playing music tracks.
This is due to the low signal / noise ratio provided by the bit Ten input head unit. If you have this problem after
you calibrated the amplifiers sensitivity (see 7.3), increase the head unit volume and repeat the bit Ten
calibration procedure as detailed in the following chapter 6.4.
CLIP
Head unit input-level instrument check.
You will need an oscilloscope for this instrument check.
• Connect the head unit output to the oscilloscope.
• Play track 1 of the bit Ten CD.
• Set tone, fader and balance controls and the equalizer (if any) to zero (flat).
• Turn on the car.
• Adjust the volume control so that the oscilloscope shows
CLIP
a sine wave with slightly cut peaks, as shown in the figure.
• Note the volume used by the head unit. It must be left in this position for the following operations.
13
ADVANCED MANUAL / bit Ten / 6
4. How to IN LEVEL calibrate the MASTER inputs.
This procedure is delicate and requires particular attention. Improper execution can invalidate the final acoustic
results. The bit Ten outputs must be disconnected from the amplifiers.
• While playing track 1 of the CD, turn the first knob towards the highest sensitivity (position +).
• When the orange LED lights up or flashes, stop turning and go back slightly until the LED turns off.
• It is normal for the LED to flash briefly; this indicates correct sensitivity calibration.
• Repeat the procedure for the other 3 Front / Rear knobs.
• Note the calibration level used by the head unit volume control.
WARNING: Some factory head units require a low load impedance to enable the outputs (usually the Rear section). If
during the calibration process the input signal level can’t be adjusted, it may be necessary to connect in parallel
a 47Ω - 3W resistor to the input cables of the channels showing the issue.
Audio systems installed as standard by car manufacturers often come with equalized outputs.
This means that the response curve is not flat and the difference between the highest and the lowest level can
reach 6 dB. By calibrating the device so that the LED never lights up, the bit Ten sensitivity may be suboptimal
(low) and you may experience noise (whistle) on the speakers. A few quick LED flashes indicate only a small
distortion when handling maximum peaks (very occasional) of music tracks.
If the source is not equalized, response is flat and the LEDs will always be on or always off. In this case,
calibrating is easy because you will simply need to adjust the knobs so that the LEDs turn off just below the
point they turn on.
6.2 SOURCE DE-EQUALIZATION
Source de-equalization (De-Eq) is only required if the source is equalized.
OEM sources (installed as standard by the car manufacturer) often have a high output level (speaker output) with preset
equalization that can not be deleted.
By replacing the factory audio system (speakers and / or amplifiers), this equalization is harmful.
The bit Ten has an automatic procedure to verify equalization and, if present, can eliminate it.
1. Equalization analysis: setting the source.
To run this procedure, follow the instructions as listed below:
• Disconnect the bit Ten RCA outputs (Front, Rear and Sub) if they are connected to the amplifiers.
• Play track 2 of the bit Ten CD.
•Set all tone and equalizer controls to zero (0).
•Set balance and fader to center (0).
•Don’t change or reset the volume of the input sensitivity calibration (see 6.1.3).
If the calibration volume is lost, to find it simply proceed again as described in paragraphs 6.1.1 - 6.1.3 and verify that the
IN LEVEL LEDs flash occasionally.
The DRC can display the calibration level, if your system has it (see 10.2).

ADVANCED MANUAL / bit Ten / 6
6.3 AMPLIFIERS SENSITIVITY CALIBRATION
Once the bit Ten input calibration or de-equalization (if any) procedures are complete, you can calibrate amplifiers sensitivity.
• Set the amplifiers crossover filters as desired and then connect them to the speakers.
• Connect the bit Ten PRE outputs (Front - Rear - Sub outputs) to the amplifiers inputs using high quality RCA cables.
• Set the amplifiers sensitivity of the various channels to about 4.0 Volts.
1. Amplifiers sensitivity calibration by listening.
• Place the head unit volume where the bit Ten inputs were calibrated and play a highly dynamic track.
• Work on the amplifiers sensitivity controls slowly bringing them to higher sensitivity (less than 4.0 Volts). Once the
first distortion symptoms show you should stop. This is easier if you work on one channel (stereo) at a time by
disconnecting the other channels / amplifiers inputs.
• Once the amplifiers are calibrated, reconnect all the system channels and, if necessary, reduce the sensitivity
(back to 4.0 Volts) of those channels that may have excessive volume.
2. Amplifiers sensitivity instrument calibration.
For instrument analysis, you will need an oscilloscope.
• Disconnect all speakers from the amplifiers if already connected.
• Play track 1 of the bit Ten CD. All source controls must be flat (0).
The volume control should be placed on the bit Ten input calibration level.
• Connect the oscilloscope to an amplifier output channel. The video will display a sine wave with variable frequency
(sweep).
CLIP
• Turn the sensitivity control in both directions until the sine
wave looks slightly cut at both ends.
• Repeat for each amplifier channel.
• Reconnect the speakers and insert a CD with a music track.
Reduce the sensitivity (by turning the knob toward 4.0 Volts)
of those channels that may have excessive volume.
CLIP
6.4 HOW TO CALIBRATE THE PHONE AND AUX IN INPUT SENSITIVITIES
Once the system is calibrated and fully working through the Front / Rear inputs, you can calibrate the PHONE and AUX
IN inputs.
- PHONE: To use this input you need to connect a phone hands-free kit (see 5.6).
Make a phone call, speak loudly and adjust the IN Level / PHONE knob until the LED flashes sporadically.
- AUX IN: To use this input you need to install the DRC (optional).
Through the DRC select AUX (see 10).
- If a source with a CD player is connected to the AUX input, disconnect the bit Ten outputs from the amplifiers
and proceed as detailed in chapters 6.1.3 - 6.1.4.
- If the source to be connected to the AUX IN input has no CD player (e.g. mp3 player), you can calibrate by listening.
A - Connect the bit Ten RCA inputs (AUX IN) to the head unit output.
B - Play a music track.
C - Turn the IN Level / AUX knobs until the first distortion symptoms appear. Check if the IN Level / AUX LEDs
flash occasionally.

ADVANCED MANUAL / bit Ten / 8
8. bit Ten INSTALLATION GUIDE USING A PC.
To configure the bit Ten inputs, outputs, equalizations and time delays, the processor must be connected to a PC
after calibrating the input levels. At that point, you need to have in mind the system you want to realize, since from this
moment if you want to change any of the settings, you will have to go through the guided procedure all over again.
More specifically the guided procedure will ask for:
- What kinds of specialization the main inputs channels use. The guided procedure changes according to your selection.
- Which auxiliary inputs will be used (e.g. AUX and / or PHONE).
- Which kind of signals will be allocated to the different outputs (e.g. Front Left, Center or Subwoofer etc.).
- Which speakers you are using for your system (e.g. 2-way Front, Front / Rear, Sub etc.).
- If the system features passive crossovers to manage speaker groups (e.g. 2-way system with active mid-low).
During this procedure, you should disconnect the bit Ten output RCA plugs to the amplifiers.
8.1 SELECTING THE MASTER (FRONT / REAR) INPUTS AND OUTPUTS - TARGET MODE
1. Connect the head unit speaker outputs to the bit Ten high-level input (see 4.2).
Before turning on the system, make sure the amplifier’s RCA plugs are disconnected from the bit Ten to
avoid speaker damage during the calibration procedure.
The input calibration procedure must be performed with the ignition turned on. In this case, the car voltage is about
14.0 volts. The head unit will provide an undistorted output signal at higher volume.
2. Make sure that the IN Level knobs for the inputs used (L / R Front, L / R Rear, Phone, Aux IN L-R) are set to minimum
sensitivity as in the figure (position -).
3. Turn on the bit Ten and connect the USB cable to a PC. After installing the bit Ten software, start it by clicking the icon
previously created on the PC desktop.
The first screen shown is the start page where you need to choose among three operational modes:

ADVANCED MANUAL / bit Ten / 8
4. If synchronization is successful, a dialog box will show the data exchange between processor and software.
Wait a few seconds and, finally, confirm by clicking the OK button.
At this point you need to have in mind the system you want to realize beforehand, since from this moment if you want to
change any of the settings you will have to go through the guided procedure all over again.
More specifically the guided procedure will ask for:
- Which auxiliary inputs will be used (e.g. AUX PHONE).
- Which kind of signals will be allocated to the main inputs (e.g. Front Left or Front Right etc.).
- Which speakers you are using for your system (e.g. 2-way Front + Sub etc.).
- If the system features passive crossovers managing speaker groups (e.g. 2-way system with active mid-low).
5. Click the Config menu and select I/O Configuration Wizard.
Press NEXT to continue configuration.
Press CANCEL to exit.
6. Select the inputs.

ADVANCED MANUAL / bit Ten / 8
7. How to setup the Master high-level main inputs.
You can assign any processor input channel the identifying name of the signal coming from the source.
The available names are: FL (Front Left Full); FR (Front Right Full); RL (Rear Left Full); RR (Rear Right Full); FLTW (Front Left Tweeter); FRTW (Front Right Tweeter); FLW (Front Left Woofer); FRW (Front Right Woofer); Sub L
(Sub Left); Sub R (Sub Right).
The bit Ten will use these names to reconstruct a full range signal coming from an OEM source with a dedicated
multi-channel amplifier and assign the corresponding signal to the respective analog output.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.

8. Setting the source.
- Turn on the system and play track 1 of the CD supplied with the bit Ten.
- Set all tone controls to zero (flat).
- Set balance and fader to center.
- Adjust the head unit volume to the maximum undistorted output level.
- If the source provides an adjustable equalizer, make sure that all controls
are set to zero (flat).
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
WARNING the head unit level must be elevated to the maximum undistorted level. If the head unit distortion level
can not be tested in advance, bring the volume to approximately 80% of its maximum. If the head unit output
level is set too low, the device will produce ground noise (hissing sound) when playing music tracks. This is
due to the low signal / noise ratio provided by the bit Ten input head unit.
If you have this problem, after you calibrate the amplifiers sensitivity (see 8.1.21), increase the head unit
volume and repeat the bit Ten calibration procedure as detailed in the following chapter 9.
Head unit input-level instrument check.
You will need an oscilloscope for this instrument check.
- Connect the head unit output to the oscilloscope.
- Play track 1 of the bit Ten CD.
- Set tone, fader and balance controls and
the equalizer (if any) to zero (flat).
- Turn on the car.
- Adjust the volume control so that the oscilloscope shows
a sine wave with slightly cut peaks, as shown in the figure.
- Note the volume used by the head unit. It must be left in this position
for the following operations.

ADVANCED MANUAL / bit Ten / 8
9. How to calibrate the bit Ten IN Level inputs.
This procedure is delicate and requires particular attention. Improper execution can invalidate the final acoustic results.
The bit Ten outputs must be disconnected from the amplifiers.
• While playing track 1 of the CD, turn the first knob towards the highest sensitivity (position +).
• When the orange LED lights up or flashes, stop turning and go back slightly until the LED turns off.
• It is normal for the LED to flash briefly; this indicate correct sensitivity calibration.
• Repeat the procedure for the other 3 Front / Rear knobs.
• Note the calibration level used by the head unit volume control.
Important: Some factory head units require a low load impedance to enable the outputs (usually the Rear section).
If during the calibration process the input signal level can’t be adjusted, it could be necessary to connect in
parallel a 47Ω - 3W resistor to the input cables of the channels showing the issue.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
WARNING: Audio systems installed as standard by car manufacturers often come with equalized outputs.
This means that the response curve is not flat and the difference between the highest and the lowest level
can reach 6 dB. By calibrating the device so that the LED never lights up, the bit Ten sensitivity may be
suboptimal (low) and you may experience noise (whistle) on the speakers. A few quick LED flashes indicate
only a small distortion when handling maximum peaks (very occasional) of music tracks.
If the source is not equalized, response is flat and the LEDs will always be on or always off. In this case,
calibrating is easy because you will simply need to adjust the knobs so that the LEDs turn off just below the
point they turn on.
10. How to select the speakers available in the system.
Speakers can be selected just by clicking on them.
If the left tweeter, left midrange or left woofer are selected, the software provides the
ability to automatically also activate the right tweeter, right midrange or right woofer.
Once started, this choice sets the dedicated crossover type and frequencies with
default settings. If you do not use passive crossover filters, each speaker corresponds
to an output channel. The bit Ten has 5 output channels; not using passive crossover
filters allows you to pilot 5 amplified channels. Of course you can select more than 5
speakers, in which case the system will help implement passive crossovers.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
24
ADVANCED MANUAL / bit Ten / 8
11. How to select passive crossovers for speaker groups.
You can set if passive crossovers exist that manage speaker functional groups.
Eg.: If the audio system has passive crossovers, the software will ask you to set them,
otherwise press NEXT. A 2 or 3-way passive crossover only takes a single
channel. If the sum of crossovers and / or speakers exceeds 5 output channels,
the software won’t allow you to continue. Recheck the crossover setting or,
by BACK, the speaker configuration.
WARNING: A coaxial speaker should be considered
a Tweeter + Woofer + 2-way Crossover.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
12.
Processor outputs (Ch1÷Ch5) allocation.
The bit Ten features 5 output channels. The software will automatically assign
a number from 1 to 5 to each crossover or speaker.
The numbers match the corresponding output channels (e.g. 3=CH3).
With DEFAULT settings, you will have: CH1=Front L; CH2=Front R; CH3= Rear L;
CH4= Rear R; CH5= Sub.
Automatic numbering can be adjusted using the cursors next to the numbers.
In case a number is repeated or incorrect an error message will be shown.
To then check if the channel number and the actual name (e.g. 3=CH3 -> Rear L)
are consistent, open the CHANNEL MAP (see 9.8.8).
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
13.
Source equalization analysis.
Source de-equalization (De-Eq) is only required if the source is equalized.
OEM sources (installed as standard by the car manufacturer) often have a high output level
(speaker output) with preset equalization that can not be deleted.
By replacing the factory audio system (speakers and / or amplifiers), this equalization is
harmful.
The bit Ten has an automatic procedure to verify equalization and, if present,
can eliminate it.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
14. Equalization analysis: setting the source.
To run this procedure, follow the instructions as listed below:
•Disconnect all the bit Ten RCA outputs (Front, Rear, Sub) if already connected to
the amplifiers.
•Play track 2 of the bit Ten CD.
•Set all tone and equalizer controls to zero (0).
•Set balance and fader to center (0).
If the calibration volume is lost, to find it simply proceed again as described in
paragraphs 8.1.8 - 8.1.9 and verify that the IN LEVEL LEDs flash occasionally.
The DRC can display the calibration level, if your system has it (see 10.2).
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
25
ADVANCED MANUAL / bit Ten / 8
15. Once analysis has completed, the following messages could be
displayed:
-Head unit is equalized: The head unit is equalized,
so we recommend to de-equalize the signal afterwards.
-Head unit is not equalized: The head unit is not equalized,
so you don’t need to de-equalize the signal afterwards.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
16. Source de-equalization.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the de-equalization.
Press SKIP to skip the de-equalization procedure and proceed to point 19.
Important: Confirm or skip the de-equalization process within 5 minutes,
otherwise the bit Ten will automatically reset and turn off.
17.
Running the de-equalization procedure.
If you decide to run the procedure, follow the instructions as listed below:
- Play track 2 of the bit Ten Setup CD (press Play);
- Set all source tone controls to zero (0);
- Set source balance and fader to center (0);
- Don’t change the source volume level previously
set through the input calibration.
Premere BACK per tornare al passo precedente.
Premere NEXT per proseguire nella de-equalizzazione.
Premere CANCEL per uscire dalla procedura.
18. Through a real-time progress bar and specific messages, the software shows
how the procedure is being executed.
Once the procedure is complete, you will see “Press Next to Continue”.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the setup procedure.
Press CANCEL to exit the procedure.
19. System configuration successfully completed.
Stop playing the Test track, remove the supplied
Setup CD from the CD player of your head unit and then click OK.
Once the de-equalization is complete, the bit Ten DE-EQ CHECK LED will turn on
indicating that you have recorded a curve. If you were to repeat the
de-equalization, new data will replace the previous ones.
To clear the memory and turn the DE-EQ CHECK LED off see 6.1.2.

Software Startup.
The settings selected during the guided procedure are transferred to
the processor main memory.
Once this operation is complete, a message confirming that the update
has been done will be displayed.
Press OK.
We recommend that you finalize the product and avoid losing data stored
during calibration (see 8.5.3) with the FINALIZE TO bit Ten function, from the
main FILE menu.
21.
Amplifiers sensitivity calibration.
Once the bit Ten input calibration or De-Equalization (if any) procedures are complete, you can calibrate amplifier’s sensitivity. If you proceed according to the following procedure, you will achieve the best acoustics results, also eliminating any possible background noise.
1. Connect the different amplifiers channels to the speakers.
2. Connect the bit Ten PRE outputs (OUTPUT: Front - Rear - Sub / CHI -> CH5) to the amplifiers inputs using
high quality RCA cables.
3. Set the amplifiers sensitivity of the various channels to about 4.0 Volts.
Then proceed according to either of the two following procedures:
A. Amplifiers sensitivity calibration by listening.
• Place the head unit volume where the bit Ten inputs were calibrated and play a highly dynamic track.
• Work on the amplifiers sensitivity controls slowly bringing them to higher sensitivity (less than 4.0 Volts).
Once the first distortion symptoms show you should stop. This is easier if you work on one channel (stereo)
at a time by disconnecting the other channels / amplifiers inputs.
• Once the amplifiers are calibrated, reconnect all the system channels and, if necessary, reduce the sensitivity
(back to 4.0 volts) of those channels that may have excessive volume.
B.Amplifiers sensitivity instrument calibration.
For instrument analysis, you will need an oscilloscope.
• Disconnect all speakers from the amplifiers if already connected.
• Play track 1 of the bit Ten CD. All source controls must be flat (0).
The volume control should be placed on the bit Ten input calibration level.
• Connect the oscilloscope to an amplifier output channel. The video will display a sine wave with variable
frequency (sweep).
CLIP
• Turn the sensitivity control in both directions until the sine
wave looks slightly cut at both ends.
• Repeat for each amplifier channel.
• Reconnect the speakers and insert a CD with a music track.
Reduce the sensitivity (by turning the knob toward 4.0 volts)
of those channels that may have excessive volume.
CLIP
4. The flattening of the functional groups acoustic intensity obtained through the amplifiers sensitivity calibration is an
approximate adjustment. The bit Ten applies the standard settings by default. After the acoustic settings
described in the following paragraphs are performed, you will be able to refine the functional groups acoustic
flattening by acting on the bit Ten outputs (see 8.13).
27
ADVANCED MANUAL / bit Ten / 8
22. How to calibrate the Phone and Aux Ininput sensitivity.
Once the system is calibrated and fully working through the Front / Rear inputs, you can calibrate the PHONE and AUX
IN inputs.
- PHONE: To use this input you need to connect a phone hands-free kit (see 5.6).
Make a phone call, speak loudly and adjust the IN Level / PHONE knob until the LED flashes sporadically.
- AUX IN: To use this input you need to install the DRC (optional).
Through the DRC select AUX (see 10).
- - If a source with a CD player is connected to the AUX input, disconnect the bit Ten outputs from the amplifiers
and proceed as detailed in chapters 6.1.3 - 6.1.4.
- If the source to be connected to the AUX IN input has no CD player (e.g. mp3 player), you can calibrate by listening.
A - Connect the bit Ten RCA inputs (AUX IN) to the head unit output.
B - Play a music track.
C - Turn the IN Level / AUX knobs until the first distortion symptoms appear. Check if the IN Level / AUX LEDs
flash occasionally.
8.2 OFFLINE MODE
In this mode, even if the bit Ten processor is connected to the PC, it does not interact with the software.
The OFFLINE mode (see 8.1.3) can be used to work on the software without connecting the bit Ten to the PC to get
familiar with the multiple processor functions or to save settings that can be used later (see 8.5.1).
The software is pre-set to start with a FRONT +REAR + SUB multi-amplified system.
To set a new “virtual” system, and so to change the inputs and select the outputs, you need to select the function I/O
Configuration Wizard in the Config window of the software main menu. Follow the same instructions as those for the
TARGET mode (see 8.1.5).
Here is how the bit Ten software appears when started in OFFLINE mode.

This window displays the names given to the output channels.
When this window is active, you can manage each channel that, once selected,
will be highlighted.
Press the CTRL key and click another channel to select and highlight it as well.
The filter curve will appear on the graph at the same time.
Multiple selection is only allowed for functional groups, except for the
Subwoofer that can be selected with any group.
E.g. Front Left Full can be selected with Subwoofer but not with Rear Left Full.
If you want to check the Rear + Subwoofer system, you have to de-select the
Front system.
The software only allows you to work on a single channel and will display the
word EDIT in red next to the corresponding channel.
In particular, the graph will display a red line for only the electrical response of
the crossover corresponding to the editing channel, a blue line for the overall
electrical response of all selected channels, taking into account the crossover
filters and equalizations, and a green line for the final result.
To act on another channel and keep your selection, click to the right
of the desired channel, where the EDIT column is.
The CHANNEL MAP window also lets you silence each channel by clicking
on the word MUTE to the left of the desired channel.
If MUTE is on, the word gets highlighted in green.
You can also select a channel as shown in the image next

Listening point visual indicator
The Select Channel window includes this function as well (shown in green).
Four points are pre-set: driver, passenger, front center and
rear center for the corresponding passengers.
This indication acts only and exclusively as a reference for the
digital delay automated calculation (see 8.11). If delays are set
according to the “driver” position and then you want to optimize
the system also for the “passenger” position, you need to set
the distances through the specific menu (see 8.11) again, as the
system doesn’t update them automatically.
If used together with the presets (see 8.14), it is useful to
try different setups according to the different listening points.

WARNING: In EXPERT mode, pay due attention to the filter selection.
Speakers have mechanical limits that must not be exceeded,
otherwise they could lead to permanent damage. When you
select a filter, some optimized cut-off frequencies are set by
default to avoid breaking the speakers.
E.g. if you select Low Pass for a tweeter, the default frequency is
suitable for a woofer but not for the tweeter, which may be damaged.
4. Filter Model: lets you select the type of filter to be applied.
- Linkwitz (default)
- Butterworth
When launching the bit Ten software, it suggests Linkwitz as the standard filter model for the
speaker or speaker group connected to the corresponding channel. To apply the opposite
(Left / Right), turn the Xover L/R Link on.
If you modify the model to Butterworth, the change will be applied to both.
33
ADVANCED MANUAL / bit Ten / 8
5.Cut-off frequencies
- Hi-P Hz
10 ÷ 20000: filter High-Pass
- Lo-P Hz 10 ÷ 20000: filter Low-Pass
If you select the Band-Pass filter, both Hi-P Hz and
Lo-P Hz boxes will be available to set the band frequency.
You can select the cut-off frequency by:
- clicking on the corresponding drop-down menu, selecting the frequency range
that includes the value to be set, and then the actual value;
- clicking on the corresponding drop-down menu, selecting the frequency range
and then moving from value to value with the arrow keys (up / down) on the PC
keyboard;
- clicking on the corresponding drop-down menu and then moving from value to
value with a mouse featuring a rotating scroll wheel.
In STANDARD mode the crossing frequency for speakers
of the same front is bound with a -3 dB crossover.
E.g. If you change the Front Woofer low pass cut-off frequency, the Front Mid-Hi hi-pass cut-off frequency will also
automatically change. If you change the Subwoofer low-pass cut-off frequency, instead, the Front Woofer hi-pass
cut-off frequency won’t change.
In EXPERT mode the crossing frequency for speakers of the
same front is free, meaning that cut-offs can be created with a
value other than -3 dB.
6.
Filter slope
- Hi-P Slope 12/24 dB/Oct (Linkwitz) 6/12/18/24dB/Oct (Butterworth)
- Lo-P Slope 12/24 dB/Oct (Linkwitz) 6/12/18/24 dB/Oct (Butterworth)
When starting the bit Ten software, it offers Linkwitz with 12 dB/Oct. slope.
Eg.If you select Band Pass as filter type, the slope will be applied to both hi-pass
and low-pass as the default slope, but it is also possible to unbind them.
The crossover filter response corresponding to the selected channel is displayed on the graph by a red curve, as in
the examples below.
Eg.: Band Pass
Crossover Frequency 80 - 2000 Hz @ 12 dB/Oct.
Crossover Frequency 80 Hz @ 6 dB/Oct. Hi-pass
2000 Hz @ 24dB/Oct. Low-pass
Crossover Frequency 80 - 2000 Hz @ 24 dB/Oct.
Crossover Frequency 80 Hz @ 24 dB/Oct. Hi-pass
2000 Hz @ 6 dB/Oct. Low-pass

ADVANCED MANUAL / bit Ten / 8
8.11 SET DISTANCE AND DELAY
8
This setting automatically calculates the time speaker sound takes to get to the
listener’s ear (Fig. 1).
Preliminary Remarks
Sound moves through the air at a speed of 343 mt/sec (1.125 ft/sec) at a
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.
If you set the distances of the different speakers in your system, the bit Ten
will automatically change them into time (ms - milliseconds). It does not
assign a delay (0.0 ms) to the farthest speaker (usually the Subwoofer)
but progressively growing delays as much as the other speakers get closer
to the listening point, in order for all the emission points to reach the listening
point at the same time.
Fig. 1
SET DISTANCE
Lets you set the distance between the speaker and the listening point. Choose cm (centimeters) or in (inches).
The Set Distance boxes can be set using the cursors or by typing the numbers on the keyboard.
DELAY ms/default
Displays the time in ms (milliseconds) calculated according to the distance.
DELAY ms/fine set
The bit Ten time delays also let you perform manual fine-adjustment.
Preliminary Remarks
Fine Set and Phase Delay
Delay assignment according to distance calculation is theoretical. That is, small variations need to be applied due
to small errors in distance measurement, back-wave reflections inside the car compartment and, mainly, the
speaker phase problem.
Two speakers reproducing two areas of frequency close to each other (e.g. Woofer and Midrange) will
simultaneously reproduce in their crossing area, 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 using Fine Set you can partly correct these problems of Phase Delay.
By using Fine Set you can change the automatically set time delay.
This delay adds to (+ x.xx) or is deducted from (- x.xx) the value of the delay
shown in the Delay / Default window, and does not change the value
automatically calculated.
Assigning a positive value (+ x.xx) with Fine Delay means increasing the delay
of that speaker and thereby takes it closer to the listening point.
Likewise, assigning a negative value (- x.xx) means decreasing the speaker
delay and therefore moves it further away from the listening point.
Fig. 2
In order for you to see how much Fine Set has been manually changed, both
delay values are shown. To see the result applied to the output, you have
to add the values shown in the Delay / Default and Delay / Fine Set boxes.
A negative value (decreasing the delay) can not be assigned to the farthest
speaker; it can only be assigned to the other speakers as they are all already
delayed compared to the farthest one. If you try and give a negative value
to the farthest speaker, an alert message will appear (Fig. 2).
When using Fine Set, the letters Fds will be shown in green on
the corresponding channel of the Channel Map (Fig.3).
35
Fig. 3
ADVANCED MANUAL / bit Ten / 8
Example of setting the time delay (Fig.4):
1. Choose the system listening point.
To identify the listening point, choose an ideal point located at
the center of the listener’s (driver or passenger) head.
For the front center and rear center points choose an
intermediate point between the two (left / right) listeners.
2. Measure the distance between each speaker or group of speakers
and the listening point in a straight line (“as the crow flies”).
For each speaker choose the center of the mobile membrane as
the emission point.
For groups of speakers choose an intermediate point between
them. It will then be possible to perform fine tuning by using the
Fine Set function. (fig.6)
3. Select the channel related to the speaker under examination on
the Channel Map and enter the respective distance value in the
Set Distance box of the Filter Settings menu. (fig.5)
4. Repeat step 3 for each channel.
5. Perform all time delays settings, start playing music and select
the Fine Set box. As you move it positive or negative (except for
the Subwoofer in Fig.6 since it is the farthest speaker), you will
find the best time alignment and correct acoustic scene.
It is advisable to listen to different types of music (percussion,
melodic, etc.) for a comprehensive evaluation of different musical
instruments (space stability.
6. Once the time alignment procedure is complete, you can work
on the output equalizer (see 8.12), to optimize the system
response in accordance with level alignment of different
frequencies.
Fig. 4
Remark: measurements for the above operations can also be taken by
using a spectrum analyzer with an appropriate microphone.
The results must be assessed with final refining listening tests.
WARNING: If, once you have set the distances for the “driver”
listening point, you click on the “passenger” listening point,
the bit Ten won’t re-calculate the delays for the new
reference point because the buttons available in the
SELECT A CHANNEL diagram are merely descriptive.
Their only purpose is to remind you that you have set the
delays for that listening point!

ADVANCED MANUAL / bit Ten / 8
8.12 GRAPHIC EQUALIZER
9
The bit Ten software features a 31-band, ± 12 dB graphic
equalizer for each system channel.
In compliance with ISO requirements, frequencies are
equally spaced at 1/3 Oct. from 20 to 20 kHz.
The equalizer works according to the functioning mode
chosen. So we have:
- one equalizer for the Front.
- one equalizer for the Rear.
- one equalizer for the Subwoofer.
Eg.: if examining the system described so far there would be:
- one equalizer for the Front Mid-Tweeter.
- one equalizer for the Front Woofer.
- one equalizer for the Subwoofer.
In order to set an equalization curve, you just have to select the channel
you want to equalize from the Channel Map menu and left-click the
slider you want to set with the mouse.
To shape an equalization curve, you just have to right-click the first
slider on the left of the equalizer and move the equalizer sliders towards
the right, shaping the curve as you like (see Fig. 1).
The graphic equalizer features five specific functions to ease
adjustments (see Fig. 2).
1.Select ALL once an equalization curve has been set, this
provides the ability to move all the cursors at the same time.
2.Flat, brings all the cursors back to the 0 dB position;
3.EQ L/R Link when active, applies the equalization curve to
both the right and the left channel simultaneously.
4.EQ Off when active, provides the ability to disable the
equalizer to check its effect without losing its settings.
5.One Select button for each equalizable band, providing the
ability to move all the selected cursors all together.

compared to its slider position.
WARNING: The CH6, CH7, CH8 output channels are only available in the digital I/O of the bit Ten D.
3 If you click the Mute button, you can mute the corresponding output channels.
If you click the Mute button again, output will resume
4 If you click the Link button, you can simultaneously adjust all the bit Ten output levels. If you click the Link
button again, the function will be disabled.
5 By clicking on the “Solo” button the output channels, with the exception of the activated one, will be muted.
By manually clicking on the “Solo” button this function will be disabled.

By using the Volume slider, you can adjust the general system volume (-60÷0 dB).
7 By using the Sub Volume slider, you can adjust the Subwoofer output level (-12÷0 dB), if the system
features a Subwoofer.
Remark: if installation includes a mono Subwoofer, the sensitivity
of its dedicated amplifier needs to be increased by +3 dB
compared to the rest of the amplifiers (see the “Amplifiers
Sensivity” chart). This empirical method takes many factors into
account and provides a better adjustment of the “Sub Level”.

2 affects the system signal / noise ratio
(whistle / background hiss).
We recommend that you always set the bit Ten output level high and the amplifiers sensitivity low, so that the
amplifiers will be less affected by noises / background hisses.
Unfortunately, a too high output level introduces clipping on the processor outputs, especially if equalizations
with high gain are applied. We therefore recommend that you proceed as follows:
a-Set the amplifiers sensitivity level at the minimum (3-4 V RMS). If you have not already done it ( see 8.1.21).
b-Balance the emission level of the system channels by moving the cursors 1 paying attention to
maintain a mid level centered at around -20 dB. Turn the output volume to an acceptable listening volume
level.
38
ADVANCED MANUAL / bit Ten / 8
c - Set the desired output equalizations (see 8.12).
d -Insert a CD with a highly dynamic track.
e - Select the Link function 5 , move the cursor and increase the output channels level until possible clipping
occurs; in this case move the cursor back at least 2-3 dB (check the value on one of the displays 2 ).
f -Increase the Volume 6 to the maximum undistorted level taking it close to “0” dB.
g -In case the signal is highly distorted with the Volume at “0” dB, you will have to decrease the output
levels 2 . If, on the contrary, no distortion occurs, you will have to increase the amplifiers sensitivity until the
first distortion symptoms show: by doing this, you will make the most of the available undistorted signal.
Ramark: This procedure leads you to set the system at “zero dB undistorted”. This is not always the best solution, since a
loss in dynamic range may occur, if you listen to a track that has been registered at a lower level or with lower
dynamic range than the track used for the setup. So a good compromise needs to be found, depending on
the listener.
8.14 MEMORY
11
The bit Ten uses memory A by default for the system’s configuration;
however, it also offers the possibility to store and recall two memories
(A, B). By pressing the MEMORY button on the main menu, different
functions are available for the featured presets.
The following features are available:
-Load All Presets: loads both memories (A/B) from a file
previously saved (.prs format).
-Save All Presets: - saves both memories (A/B) in a file
that can be recalled (.prs format).
- Load Current Preset: loads a memory previously saved
(.pro format) by overwriting the memory you are working on.
-Save Current Preset: saves the memory you are working
on in a file that can be recalled (.pro format).
-Copy Preset From: copies the content of one memory into
the current memory.
-Current Preset Default: restores the crossover and
equalization default values that would be proposed at the end
of the setup procedure.
The following data are stored in each memory:
- the filter settings for each channel;
- the time delay settings for each channel;
- the equalization settings for each channel;
- the output levels of each channel;
- listening point markers.
We recommend that you copy the parameters entered in the memory
you are using into the memory that is not being used.
These memories can be recalled through the DRC. If some memories
are not stored, they will contain the default settings.
