Audison Bit One question
So I'm thinking of picking one of these units up. This is how I think it will work:
OEM HU >>> OEM Amp (L7) >>> BitOne >>> Aftermarket Amp(s) >>> OEM or Aftermarket Speakers In future, I also understand I may be able to replace the OEM amp by a MoBridge DA1000 for a pure digital connection between HU and Processor. Some questions I still have: 1. OEM HU volume. Will the BitOne properly de-EQ at ANY volume level??? (the calibration takes place at 80% HU volume per manual) 2. Does the unit provide an input for a microphone in order to make (one-time) EQ adjustments in response to the speaker outputs in the car environment? 3. Does the unit work with the optional (but nowhere to be found) auto-eq module? I hear talks about an entry level, mid level, and high level bit one. How can you tell the difference between the units? The one I'm looking at is a BitOne.1 Thanks! |

2. No 3. So far there is only one bit one, and it does not perform any auto-EQ. I don't see how technically an auto-EQ external module -if existed- could work with another module that does summing, DSP and EQ. Auto-EQ should be done in the same device as the rest of the processing, IMO (i.e. the-someday-in-the-future MS-8). |

Actually, the L7 system seems to have some auto-loudness component to its EQ curve, so you should ONLY calibrate your bitONE at 80% volume. If you calibrated it at a lower volume, it would be trying to defeat the auto-loudness even at higher levels where it isn't present, and you don't want it to.
If you install the bitONE, make sure to buy some very small-gauge speaker wire for your connections on the inputs. The terminals are TINY. You will want a small flat screwdriver too - I used an old a/d/s/ gain screwdriver, but you may want a cheap jeweler's screwdriver that they sell at Home Depot. |

Where online can I find a BitONE? I am lucking out on finding them online.

Why do you say that? I could understand the difficulty in setup for even the average consumer, though.
I was hoping to order it and just install it myself, but I will see if there are any dealers here in town that I could order one from. dolby

Because authorized audison dealers sign an agreement to NOT sell these things over the internet, because they will get all effed up, and then the product - and the brand - will get the blame.
So any online are not warrantied, possibly black market, and probably V1 units which were glitchy at best. That's why |
