I've received some e-mails recently asking if I know if the M-Audio
Digipatch units will pass 24 bit audio. I have read in numerous forums over
the years that they pass audio bit for bit.
M-Audio's tech support is impossible to contact today (I tried) but I found
the following info online:
____________________________________________________________ ________________
______________
The Litepipe protocol used by the Digipatch, known as DT-16, is a format
intended to support 16-bit Type I ADAT devices. Other Litepipe formats are
not guaranteed to work reliably. All coaxial S/PDIF and Optical S/PDIF
(TosLink) are fully supported.
http://www.technosound.com.cy/easyconsole.cfm?id=526
____________________________________________________________ ________________
________________
Now what does this mean?.................well, my optical and lightpipe
devices work fine with these units and none of them are DT-16, to my
knowledge so does this mean that since the Digipatch Units use DT-16, they
are truncating 20 and 24 bit signals to 16 bit or should it mean that they
shouldn't work at all? I don't really know. I do know that I have never had
a problem passing optical 20 and 24 bit S/Pdif or 8 channel lightpipe
through these units so if they aren't supposed to work at all, and since
even though they aren't guaranteed to work then since they *are* working,
perhaps they are passing bit-for bit.........or maybe they are truncating to
16 bit so it *will* pass signal, but this doesn't *seem* to be supported by
the statement above. Either it should work, or it shouldn't...........it
would seem...................and if it works, since the following statement
was made:
"All coaxial S/PDIF and Optical S/PDIF (TosLink) are fully supported."
...................then it should it be supporting bit-for-bit transfers?????
I guess the answer to this question is as clear as mud...right?
One thing that the Digipatch doesn't do is to reclock signals so if your
cable runs are extremely long, you may get jitter or worse.

I talked to M-Audio tech support about this today. the guy I was talking to
was clueless about this but he said there's an lod timer still around who
was with the company when these units were being made. He was taking the day
off but he's supposed to call me tomorrow. I really curious to know if this
unit will pass bit-for-bit. I don't notice an sonic voodoo going on, but
long cable runs are a no-no with this. Eventually I'm going to get myself
one of those FriendChip thangs.

Why not just do a simple test and record a signal through it to
wavelab and check out the results on the bit depth meter...

I will try to get around to this. M-Audio tech support called today and told
me that this unit will do bit-for-bit patching at 24bit/96kHz

Just wanted to mention the other option is the Apache, and it also works up
to 24bit.

I almost bought an Apache. It looks like a very good unit and it *reclocks*
the audio. That's a biggie as far as jitter and stability are concerned.
What it doesn't have is coaxial S/PDIF so if you need to patch this way, you
will need coax>opto and AES>opto converters. This can get pretty expensive
in a larger rig. Once you get to this point, it makes more sense to look at
the FriendChip digital PB's. These look like they might be the answer to a
lot of studio routing issues.
