Can I use the Digidesign 192 interface to perform analog transfers directly from industry standard multi-
track recorders? Have you tested for frequency response anomalies on a transfer like this?
Yes you can, and yes we have.

How many Time Slots does the new TDM II bus on Pro Tools|HD have? Are there any differences in the
way those Time Slots are used versus the the way Time Slots are used on a Pro Tools| 24 MIX system?
TDM II is really quite a different bus, so it is hard to make apples to apples comparisons. While in the absolute
worst case TDM II "only" has twice the slots (at 48k), for most real world sessions it really is much more than this.
First, TDM II is a bidirectional bus that has 512 slots (256 slots at 96k) running "down" the bus and another totally
separate set of 512 slots running "up". In a sense this is really like having 1024 slots, as long as the amount of
communication "up" is fairly even with the "down". Also, slots can be "reused". Meaning that if you need a
connection between DSP 1 to DSP 3 and another connection between DSP 5 and DSP 6, TDM II will just use a single
slot. It is not uncommon for slot "reuse" to result in 2x to 4x improvement in slot usage, although it will definitely
depend on the session.
Putting these two factors together the bottom line is that with most sessions slot usage will be greatly improved on
TDM II.

What is the maximum number of 192 I/Os or 96 I/Os I can have attached to my HD system?
You can have a maximum of eight 192 I/Os, or six 96 I/Os attached to an HD system. If you are combining 192 I/
Os and 96 I/Os on the same system, the total maximum is eight, and the 192 I/Os should come first. Keep in mind,
there is a maximum of two I/Os per HD Card, so you would need at least one HD Core plus three HD Process Cards
in order to attach eight I/Os.

I have an external effects processor that is equipped with digital input and output, but it only supports
44.1kHz or 48kHz sample rates; can I connect it digitally to my 192 I/O for use with an 88.2k, 96k,
176.4k, or 192k session?
This is not possible for the following reason: the Digital Card on the 192 I/O can sample rate convert on input (AES,
TDIF, or ADAT on the digital card), but cannot sample rate convert on output (AES, TDIF, or ADAT).
As a workaround, you can go analog out to the effects processor, and return digitally from the effects processor (or
just use analog in and out to the effects processor).
