Hi shezan, you should perhaps give more info about what kind of device you are looking for. Like, live mixer digital console, just generic live input to computer without recording capabilities, mixing and/or mastering system, computer workstation HD based recording, standalone HD recorder, portable recording system, matrix system for spatialization and audio channel routing, multi channel microphone preamplifiers with digital interface? If looking for a system that hooks onto a computer, you should check the software compatibility i.e. whether the hardware actually supports the DAW software that you want to use.

There are plenty of multichannel channel audio "cards" out there, providing A-D conversion, D-A conversion or both. Most of them are firewire based and come with no more than 8 analog inputs and/or outputs. In most cases, the expansion to 16 or more channels I/O is achieved by chaining to further devices through a digital connection like for example a light-pipe cable, using the ADAT standard or others. There are a few that come with 16 channels in one unit though, like the Lynx Aurora ADDA converters. The Audiobox AB64 by Richmond Sound Design goes up to 64 channels in one box, but it is a relatively specialized device.

Quality and price vary greatly from < $1000 to around $10000 or more.
Brands or makers to look into are (in very approximately ascending price and quality order):
Behringer
M-Audio
Edirol
MOTU (Mark of the Unicorn)
RME
Lynx-Aurora (Lynx Studio Technology)
Prism
Pyramid
--
Other (specialized) systems (more used for live shows, theatre, big installations, museums and the like):
AudioBox by Richmond Sound Design
Level Control Systems (LCS)

So it all depends on what you want the system for and how much you can afford to spend.

You didn't mention Mackie's ONYX system - up to 16 channels of audio via their firewire add-on card, compatible with XP or MAC, and then there's a new offering from Alesis as well.

LOTS of good-for-the-buck stuff out there, indeed.

Also you should consider that USB or firewire does absolutely matter. USB 1 s only capable of 2 simultatious inputs at a time. I'm not sure about USB2.0. Firewire definitely has the bandwidth if you need to do 16 tracks or more.

USB 2.0 is actually a little faster than Firewire 400 protocol. (Firewire 800 is of course twice that, but it's still a newcomer...)

AFAK, Firewire has almost become the defacto standard for multitrack inputs, while USB 2.0 is more often used for peripherals, including Hard drives, cameras and chip reading devices, etc. (However, there are plenty of USB 2.0 audio input devices, too, esp 2, 4, 10 and more channel devices.)

For writing to hard drive and moving data around, I have been using either one almost interchangably, depending on what port is open on the computer at hand.

For i/o on the mixers and preamps, it's been firewire exclusively for me.

As always, YMMV.

HI,

i second the Lynx AES/Aurora! best 16 i/o for the price/

however i can give you up to 168 I/O for far less than any PT rig.
3 x RME MAdi.

another option is Sydec. (Mixstream)

Not sure after all these posts what you're looking for exactly, but here's the Alesis analog 16 input on sale at Musicians Friend online for $599.99:

(Dead Link Removed)

Like the Mackie, it's 16 inputs, each available via a firewire output, with a stereo return to monitor back from the computer. Unlike the Mackie, these sends are post EQ, which is a big issue with some folks. (Remember though, this is an analog mixer with digital sends, it's not a digital mixer per se.)

They claim it has the same A/D converters as their 24 track recorder.

With the real-world bandwidth capabilities of firewire and USB2.0 in mind (especially at high samplerates), you might consider PCI-based, like the 24io.
