The AI-1 is a very straightforward unit that performs the complex task of sample rate conversion with almost casual ease. I could detect no difference in sound quality between the input signal and the sample-rate-converted output, nor did I expect to. The only problem might arise when transferring material from a DAT machine that records with pre-emphasis; although the AI-1 passes on the de-emphasis flag, it doesn't actually de-emphasise the data. The outcome of this is that transferring tapes made on a Casio or Tascam portable DAT machine to ADAT will result in the ADAT playing back the material un-de-emphasised, so although the recording will play OK, there'll be far too much top end.

Most of the applications of the AI-1 are pretty obvious, but the slightly less commonplace uses might include transfer to and from hard-disk recorders, use of ADAT to back up stereo DAT masters, and transfer of CD sound effects material to ADAT. Ultimately, not every ADAT owner will feel a burning need to own an AI-1, but I can think of several situations where I'd have been very glad to have one around, including the times when I've wanted to sample rate convert a DAT master at the same time as loading it into Sound Tools for editing. With the AI-1, all these things are possible. Given the quality of sample rate conversion and its ability to interface between different digital standards, I feel the AI-1 is something of a bargain, when you consider that only a year ago you could have paid around £2,500 for a professional unit doing substantially the same job.
