I personally have a MIX 24 system with one MIX Core and 3 MIX Farm cards. EVERYONE should own one. It's a $30k system you can get for $400 nowdays. It's an epic system for the money with great A/D converters. Sounds professional.

The MIX 24 system also works with all ASIO and Direct I/O compatible apps (Cubase, Logic etc) but you don't get the TDM stuff there, just the pure sound card.

It's probably the best system you can get for your G4 and your wallet

[supernova777]

can u explain how one would go about getting one?
which pieces do you need?
alot of people are really unfamilar with these setups considering its a combination of diferent peices of equipment.. what do i need to do that?

For a 24 MIX or 24 MIX PLUS system you need the following:

*At least one MIX Core PCI card
This is the Core of the system (well, duh?).
Contains six (6) Motorola 56k DSP's and the hardware dongle in order to get Pro Tools TDM running. The basic MIX 24 system only concists of this PCI card.

*Any number of MIX Farm PCI cards (optional)
This is what you use to expand your TDM system.
A MIX PLUS system is a MIX Core and MIX Farm card together.
MIX Farm card is exactly like the MIX Core card, but does NOT contain the Pro Tools dongle, just the six (6) DSP's. You can use up to 11 MIX Farm cards in one MIX 24 system, making a total of 12 cards and 72 DSP's.

*Ribbon cable to connect all the cards with each other (optional)
If you have more than one card, you need this little ribbon cable.
Can be found easily for around $20USD on ebay. There are 2-connector, 5-connector and 10-connector versions of this cable avalible. Buy the 5-connector version directly, even if you only have two cards. Makes is more easy to upgrade the systems with more MIX Farm cards later on.

*An A/D interface
This is what connects you to the analog world. Comes in a 1RU or 2RU case, the 882 and 888.
Both has 8 ins and 8 outs, but the 888 has balanced XLR connections.
There are allso different versions of these. The original 882 and 888 can be used at the most for 48khz and 16bit sound. The 882/20 for 48khz and 20bit sound and the 888/24 for 96khz and 24bit sound. So what you want is the 882/20 or 888/24.

Two of these boxes can be used with every MIX Core or MIX Farm card, for a total of 24 rack boxes, 192 ins and 192 outs if you have 12 cards. Pretty much endless expandability.

*Cables
You need a single or "Y" cable depending on how many A/D boxes you want to use with each card. It's a special digidesign cable and can be found very easily on ebay.

*Software
This is the hardest part. You need at least Pro Tools 4.1, but recommended is of course the last OS9 version, which is 5.1.3. You can use this system with OSX Panther and Pro Tools 6.4.1 if you feel like that too, but the plugins are not compatible, so 5.1.3 is the best option.
TDM plugins are accelerated, but RTAS plugins can be used on the host CPU at the same time as well. It's pretty hard to find this software. I have it and will upload it very soon.

That's pretty much all you need. The cons of this system is that you really need to know what you need since you have allmost endless expandability. The pro's are the expandability, sound and power.

Personally I have a 3 MIX Farms and 1 MIX Core. Connected to the Core card is a 882/20 and that's about it. Don't need any more ins or outs at the moment, but I do need the DSP-power from the Farms for TDM plugins. Everything lives inside my Dual 1.5ghz MDD and runs 9.2.2 and Pro Tools TDM 5.1.3.

perfect! i wish digidesign could explain their own products so simply;)

I just bought a Mix 24 system. Core card, two farm cards, 888|24, cables, and even some plugins. I believe Digidesign sold this package as a Mix 3 system since it comes with 1 core and 2 farms.

The cards are good and will be relevant for tracking for many years to come. The only thing I'm worried about is the 888|24 and similar interfaces. I'm hearing some terrible things about the quality of the converters...

No need to worry. They are not transparent in the way they convert your analog audio to digital, but they are truly great. The 888 is pretty much noiseless and it makes pretty much everything you record through it sound great.

People nowdays want audio transparensy. The audio should be uncolored so to speak. The 888 colors sound, and for that reason it's known as a "bad" interface. If you like the colorization (like me and many more) they are great. They color the sound just right (in my opinion)

[Syntho]

Could you elaborate on the coloration effect these interfaces have? I've been running my rig lately and it all sounds good to me. Not too much different from other stuff I've tried.

What I mean is that they add something to the sound. Makes it warmer mostly. This is not really a bad thing, but in studios nowdays engineers are trying to make the sound going into the computer sound like it did outside the computer. For that reason the old Digidesign interfaces are not so good.

They add a sertain warmth to the sound, not found on newer HD interfaces, hence they are more "true" to the original input sound or more "transparent" so to say.

I hope you understand what im trying to say. English is not my primary language

Audiomedia III is from 1996

Converters always have some special type of LPF that works in conjunction with the sample rate. The higher sample rate = higher quality thing has already been discussed elsewhere but when it comes down to it a higher sample rate is beneficial not because of higher quality necessarily, but because it allows manufacturers to make a LPF that's less steep, which makes it easier and cuts down on cost.

I'm going to take a wild guess and say that the 'warm' sound you mention is due to the Digidesign LPF on the converters not being all that great, or at least it's being rolled back a little more than usual. That would explain the warmness of it.

[Knezzen]

So it might be. But the LPF should be the same steepness if it should cut the same frequencies, otherwise the gain in sample rate would not make any sence.
I can't really find the english words im looking for, but I hope you understand. If you want to bypass everything under 100hz for instance, the filter would allways be steep. It won't matter if you have 96khz or 48khz sample rate, 100hz is allways 100hz.

Hope you understand what I mean

Of course, with the higher bitrate comes more accuracy in the filtering as such, but you should still have the same steepness, just a higher "resolution" of the filtering.

I think that the D/A converters themself are resposible for the added warmness.

[Protools5LEGuy]

I LOVE how AMIII sounds. I like how Digi 001 converters sound 24 bits bla bla bla. But AMIII at 18 bits sounds more musical to me...It is something really hard to explain, but really fast to listen and notice...
I run the "Be There" from PT5, and "Meant to Be" from TDM PT6 on both sound cards in OS9 and prefer AMIII sound. Digi001 converters sound "cheaper" and lots of users take advantage of rosetas in LE systems. Also lots of AMIII users bought RME ADI 2

[Syntho]

I'm guessing that that Audiomedia III card is just a regular PCI soundcard released by Digidesign? It has RCA inputs on it. I'm wondering if there was an interface to go with it or if it's just standard RCA where you can run anything into it.

It's a regular sound card. Can be used for system sounds through the regular sound manager, or with music applications through Direct I/O.
I think Digidesign released a alpha/beta ASIO driver for it too.

For me is a GOOD one.

I thought Steinberg did it...
It has a Motorola 56k for DSP (?) and one Advanced Micro Devices (AMD) chip and a AMCC (PowerPC arch.)

Lots of Digital Performer users had to use AMIII or MOTU hardware at first

[Syntho]

I bet those older 16bit 888s don't sound too bad, probably just about the same as those 888|24s. Or am I mistaken?

converters should be different
With protools converters there is always controversy.  Some love the Avid whites ones (16 bits) some hate them. Some producers have warned me to go 888.24 and not 888.16. Some love 882, some hate them. It is know that blues 96k are "bad" and 192 are "acceptable". A question of money and likes I bet.

You run anything at -10. I bought at the same time a Focusrite Trakmaster as PREamplifier to have two choices along with my H&K Tubeman
