4. CONNECTION PANELS - DESCRIPTION

1 LOGO STATUS

The logo led light indicates the processor status:

- BLUE Logo On: bit Nove is switched on.

- Flashing BLUE Logo: product mode set to Upgrade Mode ON, or product being updated (see section 4.11).

2 POWER and CONTROL CABLE

The bit Nove is equipped with a 6-pole multipolar connector to manage the power supply and the different control connections.

A) + BATT (11-15 VDC): terminal to connect the power supply positive pole to the bit Nove.
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.
E) OPTICAL 2 SELECT: function to select the OPTICAL IN 2 input. This command is enabled by connecting the terminal at +12V.
F) SEL MEM D: function to enable the manual selection of the processor's preset D. This command is enabled by connecting the terminal to ground.

3 PRE INPUT

The bit Nove features 6 Pre IN signal inputs to connect the preamplified signal cables from the analog Master source. The PC Software provides the ability to customize the inputs by assigning the desired input (see 7.2.5). Adjustable sensitivity from 1.2 to 8 V RMS (see 4.8). The cable provided to be connected to the source Pre Out outputs must be wired with RCA connectors, or replaced with an optional input cable.

The bit Nove features 6 SPEAKER IN signal inputs to connect the amplified signal cables from the analog master source. The PC Software provides the ability to customize the inputs by assigning the desired input (see 7.2.5). Adjustable sensitivity from 3 to 20 V RMS (see 4.8).

FRONT VIEW

5 OPTICAL IN 1/2: S/PDIF digital inputs

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.

6 AUX: low-level auxiliary STEREO input

For RCA cables coming from additional analog signal sources. Adjustable sensitivity from 0.2 to 4.2 V RMS (point 8).

7 PRE OUT: low-level analog signal (4 Volts RMS)

Ch1 - Ch2 - Ch3 - Ch4 - Ch5 - Ch6 - Ch7 - Ch8 - Ch9. For RCA cables directed to the system amplifiers (see 5.4).

WARNING: by default, the bit Nove outputs are customized as described in (see 5.4). Therefore, before connecting

the amplifiers to the bit Nove, check the outputs configuration or perform a new configuration depending on your audio system.

8 INPUT LEVEL:

A. CLIP: input clipping indicator (see 7.2.6). The led light on indicates the presence of clipping on the selected input.

B.IN level: input signal level controls. Turning the sliders anti-clockwise the input sensitivity decreases, turning them clockwise it increases. This adjustment is important for obtaining a good noise/signal ratio and optimizing your audio system.

9 DRC: connection socket for the DRC (DRC MP optional) to set up the most important functions of the processor.

10 USB: USB (B type) connection socket to connect the processor to a PC and manage the functions through the bit Nove software.

11 UPGRADE MODE: the switch to ON position enables the update of the product in RESCUE MODE (see 8.3.1).

12 ASC-C: socket not enabled, to be used for future applications.

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 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.

Pure geometric corner lines without any text, numbers, or symbols

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.

1. 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 PC Desktop that was created upon installation.

1. If synchronization is successful, a communication window will appear showing the data exchange between the processor and software. Wait a few seconds.

1. Click on the Settings menu and select Configuration Wizard.

Press Start to continue with the configuration.

Press Cancel to exit the procedure.

5. Input Configuration

Any of the input channels on bit Nove can be given the name corresponding to the signal coming from the source. In this phase it is possible to activate/deactivate the turn on from Speaker (ART) and choose how to reconstruct the SUBWOOFER output channel.

IMPORTANT REMARK: when the PRE IN inputs are used, the "ART Enable" must be disabled.

*REMARK: disable the "ART Enable", when PRE IN inputs are used.
**REMARK: use the drop down menu to select how to reconstruct the SUBWOOFER output channel.

The bit Nove will use these names to reconstruct a full band signal coming from an OEM source with a dedicated multichannel amplifier and to assign the corresponding signal to the respective output.

Press BACK to return to the previous step.

Press NEXT to continue with the configuration.

Press CANCEL to exit the procedure.

6. Input Level Setup

• Play track 1 from the CD provided with bit Nove.
• 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).

Press BACK to return to the previous step.

Press GO to continue with the configuration.

Press CANCEL to exit the procedure.

Press SKIP to skip the level calibration procedure.

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;

Press BACK to return to the previous step. Press GO to continue with the configuration. Press SKIP to abandon the procedure. Press CANCEL to exit the program.

The software uses a progress bar and specific messages to show how the procedure is being executed.

At the end of the procedure, the window will show the equalization curves for the head unit.

Press BACK to return to the previous step.

Press NEXT to continue with the configuration.

Press CANCEL to exit the program.

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

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.

Press BACK to return to the previous step.

Press NEXT to continue with the configuration.

Press CANCEL to exit the procedure.

10. Finish

Stop playing the Test track and remove the setup CD from the source player.

Press BACK to return to the previous step.

Press CANCEL to exit the procedure.

Press FINISH to end the configuration.

11. Software startup

The software transfers the settings selected during the guided procedure to the central processor memory.

At the end of this operation, an update confirmation will appear.

The "Selected Input" window shows the active source during connection with the PC. This can be used to select the desired source. Once disconnected from the PC, you can select the input source through the DRC or through the external functions "MASTER ENABLE" and "OPTICAL ENABLE".

7.3.8 CHANNEL MAP

This window shows the name attributed to the output channels. The window is active. You can click on it to manage the individual channel that, once selected, will be highlighted. If you hold down the CTRL key and click on another channel, it will also be selected and highlighted. At the same time, the filter curve will appear on the graph area. Multiple selection is only allowed for functional groups, except for the Subwoofer, which can be selected together with any group.

E.g.: front Left Full together with Subwoofer, but not with Rear Left Full.

If you wish to check the electrical response of the Rear system together with the Subwoofer, you must clear the Front system selection. However, the software will only let you operate on a single channel and will show the message "EDIT" in red to the side of the channel that you can operate on. More specifically, the graph will show the electrical responses from the only crossover related to the channel being edited in red. The overall electrical response from all channels selected will be shown in yellow, taking into account the crossover filters and equalizations. The final result will be shown in green.

To act on another channel without losing the selection, simply click to the right of the desired channel in the EDIT column. The CHANNEL MAP window also lets you mute the individual channels by clicking on MUTE to the left of the desired channel.

If MUTE is active on the channel, "m" is shown in red.

If the SOLO function is active, "s" is shown in green.

If there are time delays on the channel, "fds" is shown in yellow. A channel can also be selected as shown in the outline in the image (see sec. 7.3.9).

7.3.9 SELECT CHANNEL 9

This window is enabled. You can click directly on the speaker or speaker system to be able to display or set the parameters for the individual channel. Once selected, the speaker(s) will be highlighted.

If you hold down the CTRL key and click on another channel, it will also be selected and highlighted as occurs with the "Channel Map"

(see sec. 7.3.8). Listening point visual indicator.

This window includes the position indicator (in red)

There are four preset points: driver, passenger, front center and rear center for passengers.

The indication only acts as a reference, allowing you to display the listening points for which the digital display calculation was optimized (see sec. 7.3.11). If you set the delays in relation to the "driver" position and then you wish to also optimize the system for the "passenger" position, you must reset the distances in the specific menu since the system does not update them automatically.

If used together with the presets (see sec. 7.3.14) it is useful to try different setups according to the different listening points.

7.3.10 FILTER SETTINGS 10

bit Nove manages nine crossover filters, one for each output channel. Each filter allows you to set the parameters of a single output channel.

1. Xover L/R Link: function to transfer the adjustments made on the Right channel to the Left one and vice versa. To activate it, you must click on the blue light, which will come on. Xover L/R Link acts on all of the adjustments of the Filter Settings except for Set Distance (Delay).
2. Invert Phase: it inverts the phase of the channel under examination by 180°. This can be done by selecting the green light which will turn on. This can be useful to solve phase alignment problems among the different filtered channels.

3. Filter Type: function to select the type of filter to assign to the channels:

4. Full Range

5. Low Pass
6. High Pass
7. Band Pass

In STANDARD mode:

Depending on the speaker or speaker system selected during configuration, a suitable type of filter will be available.

E.g.: for the Front Woofer, only Low Pass or Band Pass will be available. For Front Mid-Hi, only High Pass and Band Pass will be available, etc.

In EXPERT mode:

Any speaker system selected has any type of filter available.

WARNING: in EXPERT mode, pay attention to the filter selection. Speakers have mechanical limits that must not be exceeded, otherwise it could lead to permanent damage.

When a filter is selected, 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 could be damaged.

STANDARD MODE

FILTER TYPE Range	Low Pass	High Pass	Band Pass
Tweeter				X
Midrange
Woofer			X
Mid-Hi				X
Subwoofer		X		X
Full	X		X	X

EXPERT MODE

Subwoofer	x	x	x	x
Full	x		x	x

1. Filter Model: function to select the type of filter to be applied.

2. Linkwitz (default)

3. Butterworth

When launching the bit Nove software, Linkwitz is proposed as the filter model for the speaker or speaker group connected to the related channel. To apply the opposite (Left/Right), enable the Xover L/R Link. If you change the model to Butterworth, the change will be applied.

5. Cut-off frequencies

• Hi-P Hz 10 ÷ 20000: High-Pass filter
• Lo-P Hz 10 ÷ 20000: Low-Pass filter

If you select the Band-Pass filter, both the

Hi-P Hz and the Lo-P Hz boxes will be enabled to be able to set the band frequency.

You can select the cut-off frequency by:

• clicking on the related drop-down menu, selecting the frequency range that includes the value to be set and then clicking on the actual value.
• clicking on the related drop-down menu, selecting the pre-chosen frequency range and then moving from value to value using the arrow keys (up / down) on the PC keyboard.
• clicking twice on the related drop-down menu and then moving from value to value by scrolling with the mouse.

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 Nove software, it offers Linkwitz with 12 dB/Oct. slope.

E.g.: if you select Band Pass as the filter type, the same slope will be applied to both the hi-pass and low-pass as the default slope, but they can also be unbound.

The crossover filter response related to the selected channel is displayed graphically by a yellow curve, as shown in the examples below.

E.g. Band Pass

Crossover Frequency 80 - 2000 Hz @ 12 dB Oct. Crossover Frequency 80 Hz @ 6 dB Oct. Hi-pass

2000 Hz @ 24 dB 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

7.3.11 SET DISTANCE AND DELAY 11

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^irc C ( 68^irc 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.

DELAY ms/default

Displays the time in ms (milliseconds) calculated according to the distance.

DELAY ms/fine set

the bit Nove time delay calculation system also lets you perform manual fine tuning.

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 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.

1. 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.

2. 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.

3. Repeat step 3 for each channel.

(Fig.1)

(Fig.2)

(Fig.3)

1. 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.

2. 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"

ing point, you click on the "passenger" listening point, the bit Nove will not re-calculate the delays for the new ence 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!

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.

Remark: to select the frequency parametric pole in FINE mode, use the PC keyboard keys "CTRL + →" o "CTRL + ←".

In order to vary the "Q" factor of the equalization point selected, just scroll using the mouse wheel featuring this function or using the keys "+" and "-" on the PC keyboard.

In order to delete the changes, just put the mouse over the point, select it with the left button and press CANC on the PC keyboard.

The equalizer has specific functions that aid and ease the calibration.

1 Flat brings all the cursors back to the 0 dB position;
L/R Link, when active, applies the equalization curve to both the right and left channel simultaneously.
3 EQ by Pass, when active, lets you disable the equalizer to check its effect without losing its settings.
4 Filter lets you display the electrical response subject to filtering (XOVER), by clicking on the box (red curve).
5 Filter + Eq lets you display the electrical response subject to equalization, by clicking on the box (yellow curve).

Remark: in order to clearly display the set equalization curve, you can increase or decrease the vertical axis (dB) and horizontal axis (Hz) by moving the cursors to the side of them. The default is set to +12 dB and 0-20 kHz.
