Product Description

Bit One is a signal digital processor essential to maximize the acoustic performances of your Car Audio

system. It’s made with a 32 bit DSP processor and 24 bit AD and DA converters.

Its peculiarity is that it allows the system de-equalization of car factory systems with integrated audio pro-

cessor, to evolve and improve any car audio system.

It has 10 PRE Amp Level signal inputs, 8 Speaker Level signal inputs, optical and electrical S/PDIF digital

input and PHONE IN input for the use with cellular phones handsfree kit.

It provides 8 outputs both at preampliﬁ ed and digital level.

Each channel has 32 bands equalizer, an electronic crossover and a digital delay. To adjust the several

regulations a connection with a PC is necessary.

To regulate Bit One functions, connect the PC through the USB connection.

To start the software, click on the icon:

On the starting screen there is the choice between OFFLINE (Bit One not connected) or TARGET (Bit One

connected) mode.

SOFTWARE

OFFLINE mode (Bit One processor not connected to the PC)

In OFFLINE mode it’s possible to use the software without connecting the Bit One to the PC, just to make oneself

familiar with the different processor functions.

See section: “MAIN PAGE”.

Select MENU I/O Conﬁ guration Wizard to change inputs/outputs selections (n.4 of TARGET mode).

TARGET mode (Bit One processor connected to the PC)

Make sure that the Bit One is connected to the PC through the provided USB cable.

Before activating TARGET mode, connect power supply to Bit One and switch it on by REMOTE-IN wire as indicated

in “Connections”.

After the selection of the mode, press ENTER.

CROSSOVER FILTER

1. The LINKWITZ or BUTTERWORTH ﬁ lter crossover, available separately for the LEFT and RIGHT system.

STANDARD Mode (Conﬁ g Menù): The crossover frequency between two

speakers (Lo-Hi pass) isn’t separable.

EXPERT Mode (Conﬁ g Menù): The crossover frequency between two

speakers (Lo-Hi pass) is separable.

If the LOPASS (Woofer Left) is regulated at 300 Hz, even the

l’HIPASS (Tweeter Left) goes to 300 Hz.

If the LOPASS (Woofer Left) is regulated at 300 Hz, even the

l’HIPASS (Tweeter Left) differently.

2. XOVER-LINK Function: the crossover works on the LEFT and RIGHT channels at the same time.

If the LOPASS ﬁ lter is selected at 300 Hz for the WOOFER LEFT, even the WOOFER RIGHT woks with the LOPASS ﬁ lter at 300 Hz.

DELAY and PHASE

3. Select the distance in cm or in inches of each speaker (or speaker system if there is a passive crossover) in the listening

point.

For example, select the WOOFER RIGHT and ﬁ x SET DISTANCE to 70cm. Select WOOFER LEFT and set 30cm and continue to set the

distance for the other speakers of the system. The DELAY shows the delay (in ms) the speakers nearer to the listener have, to acoustical-

ly position them at the same distance of the further speaker that has zero delay.

4. Inverts the phase of the selected speaker

If WOOFER LEFT is selected and INVERT PHASE is activated, the signal applied to the speaker has inverted polarity, to avoid the crea-

tion of a gap at the crossover frequency matching point with another speaker (for example Tweeter Left).

EQUALIZER

5. 31 band graphic equalizer.

6. EQ-LINK function: the equalizer works on LEFT and RIGHT channels at the same time.

In this way the graphic equalizer works separately on FRONT - REAR - CENTER – SUB system.

If a FRONT system speaker is selected and the equalizer is regulated, this works on all the FRONT system speakers (woofer left, woofer

right, tweeter left, tweeter right, etc)

EQ-OFF function: disactivates the equalizer (for the selected speaker), without moving the cursors.

FLAT function: resets all cursors at 0dB.

7. Buttons to move various cursors at the same time

If the buttons on 40-50-63-80 are activated, moving the cursor 80 even the other three move.

SELECT ALL function: allows the movement of all the cursors at the same time.

SPEAKERS - MUTE

8. Select the speakers to regulate, by means of the crossover, the phase, the delay and the equalizer.

EDIT shows the application of the regulations to the selected speakers.

9. Select MUTE on the speaker you want to silence, reselect to activate it.

The word lights and indicates that the selected speaker is off.

DISPLAY

10. Shows the crossover and equalizer response curve, for the selected speaker.

The RED curve is the crossover ﬁ lter. If the equalizer changes, a green curve appears.

11. Buttons to show the crossover and equalizer response curve.

The SUM button sums the two curves and shows the signal that is sent to the selected speaker.

12. The source you are listening to.

13. To show various curves select the various speakers (8) keeping the CTRL button on the PC pushed.

To modify a speaker select EDIT near one of the writings in evidence.

The BLUE curve shows the sum of the selected speakers responses, including the equalizer.

The GREY curves show the crossover ﬁ lter action on each speaker selected with the CTRL button.

The RED curve shows the signal and the speaker you are regulating.

MEMORIES

14. Recalls the A - B - C - D memory, to have four different setups.

To create, save, copy and manage the memories go to: Memory menù

15. Visual indicator of the listening position.

Used with the memories, it is usefull to make different setups for different listening positions.

STANDARD Mode (Conﬁ g Menù):

works separately on FRONT LEFT - FRONT RIGHT

REAR LEFT - REAR RIGHT - CENTER - SUB.

EXPERT Mode (Conﬁ g Menù):

works separately on every speaker.

If a FRONT LEFT system speaker is selected, for example the

WOOFER (left), and the equalizer is regulated, this works even on

TWEETER (left).

12. Volume level of each preampliﬁ ed output

13. Main output volume level. It moves the level of

whole outputs without changing it singularly

14. Sub channel volume level (speciﬁ c).

It performs on the channel identiﬁ ed as Subwoofer.

Dynamic Equalizer

Specialized for SUBWOOFER

At low level listening, the feeling about the bass frequencies is lower than at high level listening.

Better explaining, when low level listening, the subwoofer needs a higher level to feel it. When high level listening,

the subwoofer level has to be linearized as the sound of the other speakers.

The Dynamic Equalizer makes this regulation of the bass frequencies automatically and gradually, following the

signal level and according to the listening volume of the system.

To activate this function select the menu Conﬁ g Dinamic Equalizer Wizard.

The software enables two different modes, ADVANCED and EASY

SEL Key: It enables the selection of

DSP memory (Presets) – Dynamic Equalizer – IN level

DSP memory: it recalls the memories (A/B/C/D) set into the Bit One

AutoIN Level Adj: controls the calibration level of the MASTER source.

If OEM source has its own equalization, it can change according to

volume level set by the user. It is important, particularly if you use the Software function

“OEM De-EQ” (cut off the source Equalization) do not move the volume of the source,

in order to not change the timbre of the sistem.

To change the overall volume, use the knob of DRC.

If the listener moves the volume of the Master source, to set it correctly

at the level of initial calibration (in the absence of information on OEM source) insert the

CD (track 1) into the source, press “yes” button and adjust the volume (of Master source )

to bring the cursor (+), indicated on the display, on “0” and not more (hard clipping condition).
