It features a 32-bit DSP processor with 24-bit A/D and D/A converters. It can be interfaced to any OEM system, even on
vehicles equipped with integrated sound processor, since thanks to the de-equalization function, the bit Nove will
deliver a linear signal. It is equipped with 10 input signals, 6 Hi-Level/ Pre In, 1 Aux stereo, 2 digital Tos Link S-PDIF and
provides 9 PRE OUT analog outputs.
Each output channel is provided with: an equalization group graphically adjustable, a 68 steps frequency electronic
crossover and Butterworth or Linkwitz-Riley type filters with slopes from 6 to 24 dB / Oct and a time-delay line.
The bit Nove also features preset configurations which can be selected by the user via the remote control device DRC AB.
WARNING: 1.ToinstallthesoftwareandconguretheproductitisnecessarytouseaPCwithWindowsVista,Windows7or
Windows 8 operating system, minimum 2 GHz processor, 1 GB RAM and a graphic card with a minimum resolution
of 1024 x 600 pixel and 512 MB hard disk memory available or more.

B) – BATT (Ground): terminal to connect the processor’s power supply negative pole. Connect the negative battery
cable or a cable connected to the car’s chassis.
To fix the ground connection (-) correctly use a screw already available on the vehicle’s chassis; remove any paint
or grease residue if necessary, ensuring that there is a continuity between the negative terminal (-) of the battery
and the fixing point. If possible, connect all audio components grounds to the same point as this solution is
necessary to reduce the majority of parasitic noises which may arise during reproduction.
WARNING: observing the polarity of the connection as indicated on the terminals is essential. An incorrect connection may
cause damage to the bit Nove. After switch on, wait at least 10 seconds before turning the processor on.
C) REM IN: terminal to turn on the bit Nove via the Remote Out output of the audio signal source. The applied voltage
must be between 7 and 14.5 VDC. If you are using a source with BTL amplified outputs, the bit Nove can turn on
automatically (see section 7.3.4.6), so you will not need to connect the REM IN terminal.
D) REM OUT: output terminal for the remote turn on of other devices/amplifiers connected to the bit Nove. The processor
takes 2 seconds to provide the REM OUT to the output, but you can manually set this delay with the
software (see section 7.3.4.6). This output has a current capacity of 150 mA and can drive an automotive relay.

bit Nove /
The bit Nove accepts PCM input signals with a maximum sampling frequency of up to 192 kHz 24 bits, therefore it
is not possible to reproduce DOLBY DIGITAL (AC3) coded multichannel signals from audio/video sources (such as
the audio from a movie on DVD) or DTS (see section 4.2). The selection of these inputs is possible by using the DRC
external control or by activating it through the terminals.
OPTICAL 1. Connect a fiber optical cable with TOSLINK connector.
OPTICAL 2. Connect a fiber optical cable with TOSLINK connector.
Remark: during the fiber optical cables wiring, the minimum curve radius should be 40 mm.
A bending above this value will cause the cable to break and the consequent interruption of the digital signal.

7. HOW TO SET UP THE BIT NOVE USING A PC
7.1 OFFLINE MODE
OFFLINE mode can be used to analyze the software without connecting the bit Nove to the PC to become familiar
with the numerous functions of the processor. (For specific functions, see TARGET mode section 7.2). To activate the OFFLINE
mode, the device must be disconnected from the PC. The software is preset to start with a 3 way active FRONT +
REAR full multi-amplified system. To set a new "virtual" system and thus change the inputs and select the outputs,
select the function Configuration Wizard in the SETTINGS window of the software main menu.
Remark: Change the size of the window for the PC software.
• To make the window full-screen, click on the Enlarge button or
double click on the title bar of the PC Software window.
• To restore the previous size from full-screen, click on the Reset
button or double click on the title bar on the window.
• To resize the PC Software window (make it smaller or larger),
position the mouse pointer on one edge or corner of the window.
When the mouse pointer becomes an arrow with a double point, drag
the edge or corner to make the window larger or smaller.

USER’S MANUAL
7.2 TARGET MODE
In order to configure the inputs, amplified and pre-amplified power outputs, EQ and time delays for bit Nove, it must
be interfaced with the PC. When you get to this point you must already be aware of what type of system you intend to
set up. In order to change these choices at a later date, you will need to perform the guided procedure again.
The guided procedure will request:
- The type of specialization for the main input channels used. The guided procedure changes according
to your choice.
- The type of signals that will be assigned to the main inputs (e.g.: Front Left or Center or Subwoofer, etc.).
- The speakers in the system (e.g.: 3 way Front or Sub Stereo or 2 way Rear, etc.).
- If there are passive crossovers that manage groups of speakers (e.g.: 3 way systems with active midrange).
- If you intend to use an external monophonic amplifier to drive a Subwoofer or an external amplified subwoofer.
- If you intend to use the bit Nove amplified outputs in BRIDGE configuration, thus increasing the power
on the output.

WARNING: during this operation, we recommend disconnecting the PRE OUT connection.
1. Connect the speaker outputs or the source Pre Out outputs to the bit Nove INPUTS terminal (see sec. 5.2). Before
turning the system on, make sure the PRE outputs are disconnected from the bit Nove to avoid damaging the
speakers during calibration.
The input calibration operation must be performed with the vehicle engine running. In this case, the voltage is
about 14.0 V. The source will provide an undistorted output signal at higher volume.
2. Turn the bit Nove on and connect the USB cable to the PC. Start the bit Nove software by clicking on the icon on

The input level calibration procedure is a delicate operation and must be performed very carefully. If not performed
correctly, it can nullify the final acoustic results.
WARNING: the head unit level must be adjusted to the maximum undistorted level. If the initial head unit
distortion level can not be determined, adjust the volume to approximately 80% of its maximum. If the
head unit output level is set too low, the device may produce ground noise (hissing sound) when playing
music tracks. This is due to the low signal / noise ratio provided by the head unit to the bit Nove input. If
you experience this problem, after calibrating the amplifiers sensitivity levels, increase the head unit
volume and repeat the bit Nove calibration procedure as detailed in point 9 of this paragraph.
IN LEVEL calibration for MASTER inputs
This operation is delicate and must be performed with utmost accuracy. An incorrect execution can invalidate the
final acoustic results.
• When track 1 of the CD is playing, rotate the first potentiometer to the highest sensitivity (position +).
• As soon as the orange LED lights up or blinks, stop the rotation, turn slightly backwards until the LED turns off.
• Perform the same operation for the other inputs used in the bit Nove.
• Brief activations of the LED lights can be considered normal and indicate the correct calibration of the sensitivity.
• Repeat the operation for the other 3 Front / Rear potentiometers.
• Note down the calibration level indicated by the source volume controller.

7. De-equalization
De-equalization of the OEM source, operation not required and
not necessary if using low level inputs (Pre out).
During the high level input configuration procedure, this function
can be used to maximize use of the OEM head units, even if
they were equalized to adapt best to the acoustics of the car
they are installed in. The de-equalization procedure performs
an analysis of the electrical frequency response coming from
the various channels on the OEM head unit and automatically
applies an equalization opposite to the original one, generating
a linear signal that is much more suitable to driving high quality
audio systems. Regardless of the input channels used,
the de-equalization will be performed by functional groups.
E.g.: even if using Front Left Full and Front Right Full as inputs, the software will also perform the de-equalization
on the Rear, Center and Subwoofer since the processor must use the signals identified as Front to also control
any possible Rear, Center and Subwoofer outputs.
If you decide to perform this procedure, follow the instructions below:
- Insert the supplied Setup CD if the source used is an audio CD player;
- Play track 2 (press Play);
- Set all tone controls to zero (0);
- Set the balance and fader to the center (0);
- Don’t change the adjusted volume previously set through the automatic input level calibration;

8. Speaker Connection Setup
The speakers in the system can be activated
by simply clicking on them.
The software assumes that if the Left tweeter, midrange or
woofer are selected, the Right ones are also activated.
Once the software is started, this choice will affect
the crossover type and frequencies with Default settings.
If passive crossover filters are not used, each speaker
corresponds to an output channel.
Selection of passive crossovers for groups of speakers
The presence of passive crossovers managing functional speaker
groups can be indicated.
E.g.: if the audio system features passive crossovers, the software will
ask you to set them by clicking on , otherwise press NEXT.
A 2 or 3 way passive crossover occupies a single output channel.
If the sum of the crossovers and/or speakers exceeds
the occupation of 8 PRE output channels, the software will not
allow you to proceed with the next operation. Check the crossovers
configuration again or, using BACK, the speakers setup.

WARNING: one coaxial speaker is considered a as
Tweeter + Woofer + 2 way passive crossover.
9. Output Configurations
bit Nove features 9 output channels. In this specific step
of the procedure you can assign any signal to one
of the output channels.
E.g.: The 3 way front can be controlled as:
- multi amplified (6 output channels are needed);
- passive midrange + woofer amplified separately
(4 output channels are needed);
- 3 way passive (2 output channels are needed).
During the selection, the software will automatically notify that
the 9 output channel limit has been respected, the warning
message will disappear and the NEXT button will appear.
For convenience, if output 1 is assigned to the left Tweeter, the
software will automatically assign output 2 to the
right Tweeter. During the procedure, if the left midrange speakers
are also assigned to output 1, the software will display a warning
message. Simply change the assignment of one of the two
numbers in red and the software will automatically position it to
the first available channel.

2000 Hz @ 24 dB Oct. Low-pass
2000 Hz @ 6 dB Oct. Low-pass
This setting is based on an automatic system that calculates the time
needed for the sound to get from the speaker to the listener's ear.
Preliminary remarks
Sound moves through the air at a speed of 343 m/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 the sound takes to get
to the listener’s ear.
If you set the distances of the different speakers, the bit Nove will
automatically change them into time (ms - milliseconds). It does not
assign a delay (0.0 ms) to the farthest speaker (usually the Subwoofer)
and 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.
SET DISTANCE
Function to 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.

USER’S MANUAL

Preliminary remarks
Fine set and Phase delay
Delay assignment according to distance calculation is theoretical.
Small variations must be applied due to small errors in distance measurement, back-wave reflections inside the car
and, primarily, the speaker phase problem.
Two speakers reproducing two frequency areas that are close to each other (e.g.: Woofer and Midrange) will
simultaneously reproduce the same frequencies in their crossing area, at a attenuated level. Due to the different
nature of the speakers, they will have a phase difference that, for a short frequency interval, acts as a time delay.
By using "fine set", you can partly correct these Phase Delay problems.
By using the "fine set" button, you can change the
automatically set delay time.
The delay is increased (+x.xx) or decreased (-x.xx) by
the delay value shown in the window "Delay/default" and
does not change the value shown, which is the one that
is automatically assigned.
Assigning a positive value (+x.xx) using "fine delay"
means increasing the delay for that speaker and thus
moving it farther away from the listening point.
Likewise, assigning a negative value (-x.xx) means
decreasing the speaker delay and thus moving it closer
(Fig.1)
to the listening point.
In order for you to see how much “Fine Set” has been
manually changed, both delay values are shown. To see
the resulting delay, physically 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
attempt to give the farthest speaker a negative value, a
warning message will appear (Fig. 1).
When using "fine set" "fds" will appear in green on the
corresponding channel on the "Channel Map" (Fig. 2)
Example of setting the time delay (Fig. 3):
1. Choose the system listening point.
To identify the listening point, choose an
ideal spot in the center of the listener's head
(driver or passenger).
For the front center and rear center, choose a
point between the two listeners.
2. Measure the distance in a straight line from each
speaker or group of speakers compared to the
listening point. For each speaker, choose the center of
the mobile membrane as the emission point.
For groups of speakers, choose a point between them.
It will then be possible to fine tune it using the Fine Set
function.
3. On the Channel Map, select the channel related to the
speaker under examination and enter the respective
distance in the Set Distance box in the Filter Settings menu.
4. Repeat step 3 for each channel.

5. Once the time delay settings are complete, start the
musical reproduction and use the Fine Set box, moving
the values up or down (except for the subwoofer since it
is the farthest speaker) to fine tune the system for
optimal sound. We recommend listening to various
types of music (percussion, melodic, etc.) for better
evaluation of the coherence (spatial stability) of the
different musical instruments.
6. Once the time alignment procedure is complete, you can
work on the output equalizer (see sec. 7.3.12) to optimize
the system response based on the level alignment of the
various frequencies.
Remark: measurements for the above operations can also
be taken using a spectrum analyzer with a suitable
microphone. The results must be evaluated and
optimized through listening tests.
WARNING: if, once you have set the distances for the “driver”
listening point, you click on the “passenger” listening point,
the bit Nove will not re-calculate the delays for the new
reference point because the buttons available in the SELECT
CHANNEL diagram are merely descriptive. Their only purpose is
to remind you that you have set the delays for that listening point!

7.3.12 PARAMETRIC EQUALIZER
The bit Nove software provides an equalizer, that can be managed from
a maximum of 10 graphic control points which automatically place a
maximum of 10 parametric equalization points. The quantity of graphic
control points used doesn’t match the parametric poles quantity, which
is determined by the adapting software.
The equalizer works according to the functional groups and so
we have the following factory configuration:
- one equalizer for the Front Tweeter.
- one equalizer for the Front Mid
- one equalizer for the Front Woofer.
- one equalizer for the Rear.
To be able to change the parameters for the equalizer in order to set
an equalization curve, just choose the channel to equalize from the
“Channel Map” menu, positioning the mouse over the point to be set,
and shape the curve using the left mouse button (green curve), or with
the arrow keys “← → ↑ ↓” on the PC keyboard.
