I'm not familiar with the TetraMic, but the Traveler is a firewire interface, basically all you do is plug it in to an available firewire port in your PC and plug your sound sources into the Traveler. I've heard good things about the Traveler, but I know for a fact that there are more cost-effective solutions for recording just four channels. Creative is a big no-no for music production. Others can advise with greater detail. Hope this helps.

Hi,

Thanks for your info.

The requirement of TetraMic is that the gain of the four pre-amp has to be matching very closely. Hence the manufacturer suggested Traveler with its precise (seems to be discrete step) gain control. Is there any other audio interface which provides this kind of functionality?

Try the DAV BG2 4-channel pre-amp. It's got stepped matched gain controls for each channel that can be set and re-set repeatably and accurately. It is just a pre-amp and does not have a computer interface. You would need an ADC after it, or else feed the outputs into a digitizing interface acting as an ADC. Beware that the output levels are high (clipping at +29dBu).

Here is what I use. motu 828

Google it!

I never knew that there was such a unit that could do what the 828 claims to do. Now I know what I really need to be saving my money towards! Thanks

I like the Pre-amps, well I may not know the diff either.
but its a digital mixer 20 in and 22 out. I use 3 or 4 LOL.
you can patch through to your daw, run through a plug-in (or comp),
come back to the motu and out the mains live with very little latency.

I use the USB-2 version
