Audison Bit One Signal Interface Processor

Back to last page

SKU: au-bitone
Brand: Audison
RRP: $1,699.00 Incl. GST

+ Installation required +

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.

 

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.
  • outputs up to eight channels of low level signal for use with traditional amplifiers. Each output is completely independent of each other.
  • support 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”.
  • features conventional Remote In and Remote Out terminals wired with removable connectors as found on all wired inputs. +

The Bit One has been praised as one of the best innovations of the car audio industry. If you plan to replace your factory amp then you will want to consider the Bit One. It can be used stand alone, or can be used with our PreOne or DA1000 fiber optic pre-amp.

When you open the box you get a neatly packed and wrapped Bit One Processor and DRC. Underneath the packaging you find the quick set up guide, setup disc, AC link cable for the DRC, and AD link for balanced audio to Thesis amps. It also includes a USB cable and some mounts for the DRC. The setup guide has some basic information and a huge picture of the layout of the Bit One and proper connections.

Once you install the included software it is time for setting up the Bit One. This is a fairly simple process, and the software walks you through each step by step. Setup is pretty similar for each type of installation (low level or high level). You just have to assign which inputs you are using. During setup you can establish the input level and when using it as OEM integration it will flatten out the inputs. That actually works very well.

The next step is to assign outputs. The Bit One will ask you to determine fronts, rears, and subs. You can assign channel numbers and whether or not the front and rear speaker have passive crossovers between the mid and tweet. Once this is all done, you will be asked to insert the setup disc into your CD drive and turn the volume up to just before clipping. The Bit One will set the output levels to ensure no clipping occurs.

The Bit One gives you many features to get your system tuned in just right. First you have to determine if you use a full range, high-pass, low-pass or band-pass crossover. Then you set the crossover type: you can use either Linkwitz-Reiley or Butterworth type networks. Crossover frequency is highly adjustable. It is grouped into different frequency sets and then broken down further from there. Next you will need to decide on where you want your listening position to be set for the time delay. To set the delay simply measure all your distances and enter them for each speaker. The Bit One will set the delays automatically (there is also the ability to fine tune the delay in .02 milliseconds). In addition, there's a phase inversion button to invert the phase of any speaker as well as a left/right crossover link.

The equalizer is 31 band 1/3 octave per output channel (in expert mode) that can be set for each individual channel or for linking the left/right respective channels (i.e. left and right front tweeters). For both of our setups we used the L/R link. It is recommended that you have an RTA (real time analyzer) available to help you properly adjust the EQ settings. Adjustments are made in .2 dB increments to + or - 12 dB. Once you have all of your tuning done you simply finalize the setting to the processor and you are good. You can save the setting to you computer (just in case.) you have a total of four setups you can program in. Another nice feature is the Dynamic EQ for the subwoofer. For lack of a better term this is a highly adjustable loudness feature.

The Bit One includes a DRC (Digital Remote Control) that is used to select different inputs, to switch between the four preset tunes and to adjust the Balance, Fader and Subwoofer volume. It is also used as the master volume for all input sources. The DRC is a well built unit. It feels high-end; it definitely does not feel flimsy when you hold it. The high-end feel is accentuated by a blue back lit screen. (I do wish this had selectable colors to make it match the interior lighting.)
