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 preamplified 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 Configuration 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.

TARGET mode (Bit One processor connected to the PC)
1. When software starts, it scans the USB ports of the PC, searching for the Bit One;
2. Bit One found: the processor is connected to the PC;
3. Bit One NOT found: the processor is not connected to the PC; Press CANCEL to start the OFFLINE mode;
4. Inputs/outputs configuration wizard;
5. Select the MASTER inputs being used (low level or high level) and the auxiliary inputs AUX1 - AUX2 -
S/PDIF - OPTICAL - PHONE if used;
6. Assign the processor input channels to the signals coming from the sources (Ch1 Ch6);
7. MASTER input level setup (low / high level). Follow the instruction shown on the windows;
Note: the setup is necessary to adjust the Bit One input sensitivity to the signal coming from the sources;
8. Wait until the setup is completed;
9. Input level too low;
10.Selecting the MASTER High Level input, the OEM source de-equalization function will be active;
11. If the de-equalization function is active, follow the shown instructions;
12.Select the loudspeakers used in the system;
13.Select any passive crossover filter;
14.Assign the processor output channels to the corrispondent amplifier being used (Ch1 Ch8);
