<p>Dear David: <br>
</p>
<p>The MOTU interface does not have any available SRC and it does
not have an option to sync to the USB, ever. Which is a good thing
given the nature of USB. <br>
</p>
<p>In fact, ALL USB interfaces give you clock options based on their
I/O sections (AES, SPDIF, Analog), not on their connnection to the
computer (USB). Generally the USB just carries DATA between the
computer and the interface, and any clock that may be in the USB
is ignored. Industry practice is to try to ignore any clock in a
USB line and to use a handshake and FIFO method to exchange data
via USB. <br>
</p>
<p>The MOTU can only sync to AES/EBU or wordclock or SPDIF or be on
internal clock. The DAW itself may or may not do bad things with
sample rate. You want to avoid those sorts of DAWs (the kind that
adapt to any incoming rate and perform an SRC on the fly.... ouch!
Apple is notorious with that in their operating system. That's why
you can intermix any sample rate material in iTunes without
getting a glitch, if using an Apple internal interface. <br>

Bob, what I was getting at is that some of these interfaces sync
to the USB and perform a sample rate conversion no matter what. If
the MOTU doesn’t do that, fine.

<p class="">Dear Jim:</p>
<p class="">I don't know what David is getting at. If
you put your DAT machine on internal sync and lock the
MOTU via SPDIF or AES/EBU it will do a good job
capturing the DAT.</p>
<p class="">The major cautions working in this mode
(slaving to the DAT) is some DAT machines revert to
outputting 48k clock when they are stopped, so you
need to ensure that the DAT machine is putting out the
intended (44.1k) clock before you hit record in your
DAW. And if you have a MOTU control panel, watch what
rate it says it is slaved at.<br class="">

class="">I need to transfer a few dozen DATs to a hard
drive for archiving before it's too late to find
hardware on which to do it. 20-25 years ago when I was
recording this material, I had a tower machine set up
as a DAW with all the interfaces needed to do the
transfers. It's been 15 years since that machine was
booted, and it was more than ten years old then. And I
don't remember the logon. :) <br class="">
<br class="">
So I need advice about hardware. I still have the
Tascam DA-P1 on which they were recorded, but I'm not
sure it will live long enough. I'll try it first. It
outputs S/PDIF, so I need an interface to get into my
Windoze machines. All use USB, but I think I might
have one with Firewire. <br class="">
<br class="">
I found a MOTU 8D with USB 2.0 and S/PDIF I/O. David
Josephson has cautioned me that some interfaces may
not sync well enough to the stream for a clean
transfer. Can anyone advise about this particular
product? The material is all acoustic jazz with
important artists, so quality is paramount. Most if
not all of the masters are 44.1. <br class="">
<br class="">
Can anyone suggest another interface? Also suggestions
of a source for a good used DAT if mine doesn't make
it through the process? I'll be 80 in the fall, my
last recording was 12 years ago, this project is going
to be a one-off, so I don't want to spend big bucks if
I don't need to. <br class="">
<br class="">
Thanks, Jim Brown <br class="">
