Thank you for your submission to the Edirol FAQ system on 8/6/2003 2:10:27 PM. Your question is answered below:

Question:  The specs state:  AD/DA Conversion: 24 bit Linear

However, the UA5 also outputs 16-bits.  *How* does the UA5 output 16-bit data?  Does it truncate 24-bits to 16?  Does it dither?  If it dithers, using what word-length reduction scheme?

Thanks.

Answer:

The UA-5 always outputs 24 bit data when in advanced mode, and really does not ever truncate data.  However, if you setup your software to record in 16 bit mode, it will truncate what the UA-5 is sending to the input.

The UA-5, in standard mode, will operate in 16 bit native mode, with no dithering or truncating neccesary - simply inputting and outputting as though it was a 16 bit audio interface.

It took them 3 weeks to process and respond to my FAQ submission....  and even then their answer was incredible vague.

When I think "Why didn't they do this or that on the UA5", I remember their support, and remember that practicality isn't part of Edirol.

Too bad, the UA5 is a beautiful product and could really take on some higher prices boxes with the right modifications.
