    RTA Measurement Hardware

    I am in the market for a USB pre-amp for doing in-car RTA measurements, and as far as I can tell, the M-Audio Mobile Pre is the overwhelming favorite for this application.



    Are there others out there that do everything the Mobile Pre does?

    Yeah, I haven't found anything that works better in that price range or lower. It's all you need.

    I use the M-Audio FireWire Solo, or at least I used to. Don't know the relative cost, though. I don't think the Mobile Pre was around when I bought the FWS.

    Lately, almost every measurement I've done has been with an Audyssey tower mic plugged directly into my MacBook.

    I use the same mic. Usually it is plugged directly into my HP laptop.

    I was skeptical at first, but after Nguyen's comparative measurements of his Alpine-badged Audyssey tower to his calibrated (Behringer?) mic, I was convinced that the ease of use/carrying exceeds any potential small error in accuracy for most jobs.

    Edit:

    This one looks like a winner for $25

    So I would just need an adapter to make it 1/8'' to plug into mic port and TrueRTA, etc will recognize it, huh?

    Yep. But they're a lot cheaper from other sources. I think that there are also two versions. One is capable of handling higher output than the other. I don't know which one ships with the Alpine, but given its age I would assume the lower-output one. (The newer one came about with Audyssey Dynamic EQ.)

    That mic likely needs bias voltage unless it has a battery in it. And if you build a funky adaptor to convert it to XLR, then toss phantom power at it, you can kiss that mic goodbye.

    I wonder what the story is, because people are doing it with success:
