Bit One.1

Description

Bit One is a multi-function digital processor capable of interfacing with any analog and/or digital source, turning any ordinary system into one with very high-level performance. Despite its compact size, the Bit One is equipped with a powerful, latest generation 266 MHz / 32 bit floating point DSP microprocessor, working in real time on all the functions of the most complete systems. Managed and configured by a simple and intuitive computer software, it is possible to make adjustments to improve the signal through each phase of its path; from input to output.

Features

  • Speaker-In The Bit One will automatically sum up to eight channels of hi-level input, and with the supplied CD/ DVD will automatically flatten out any factory equalization curve and set input levels
  • Phone The Bit One features a momentary audio interrupt feature for devices such as Bluetooth or navigation even when the main system is turned off
  • Pre-In Up to six channels of low-level input, such as those found on aftermarket source units can be input into the Bit One with input levels automatically set with the supplied CD/DVD. Either the lo-level or hi-level inputs must be chosen as the “Master Input”
  • AUX 1 – AUX 2 Up to two separate lo-level auxiliary sources can be input into the Bit One
  • Digital-In Two digital sources, one coaxial and one optical fiber can be connected to the Bit One
  • AC Link Connected to the Bit One through AC Link, the DRC provides remote control of basic audio functions such as volume, balance, fader and subwoofer level control as well as switching between connected sources and system presets for different EQ, crossover and time alignement settings. When used with AC Link provided amplifiers, the DRC will also display all of the ASC controlled parameters o each amplifier in the system
  • AD Link The Bit One features the proprietary Audison AD Link system which outputs up to eight channels of digital audio through one CAT 5.S cable terminated with RJ45 connectors such as those found on network LAN lines. This system provides high quality transfer of the delicate audio signal from the Bit One to the amplifiers, void of radiated noise and other electrical disturbances
  • Pre Out The Bit One outputs up to eight channels of low level signal for use with traditional amplifiers. Each output is completely independent of each other
  • Remote In/Out The Bit One features conventional Remote In and Remote Out terminals wired with removable connectors as found on all wired inputs
  • Key Switch – Power The Bit One can be turned on through the “ignition key” circuit of the car, and with the memory wire connected, remembers its turn-off state when re-powered. The Bit One can also be turned on/off with ART™ through the hi-level inputs
  • USB Connector USB 2.0 to connect the processor to a PC and manage its functions through the Bit One software

Bit Ten D

Description

bit Ten D is a multi-function digital processor conceived and built to process digital and analogue signal both on the input and on output to the amplifier (featuring AD Link connection) and create top-performance system with any source typology.

Provided with a 32 bit, 147 MHz clock speed DSP as well as 24 bit A/D and D/A converters, bit Ten D processes the signal with extreme accuracy and wide configurability thanks to a software especially designed for car acoustic peculiarities.

bit Ten D features an optical digital input, minimizing interference and degradations of the signal found in traditional analog interconnects, also by-passing the A/D conversion phases of analog signals.

Thanks to the AD Link connection, the available outputs become 8 in total, all in digital format; they can also be used simultaneously with the analog ones (for a maximum of 8 outputs total).

The AC Link is completely dedicated to the “remote control” of the system. The system is comprised of one connector for the provided DRC and one for the amplifiers present in the system. The DRC is supplied with the bit Ten D product.
