Also there's a lot to be said for tuning with aftermarket systems (even CarPCs), having EQs set for the amplifiers and speakers you have can sometimes make a big difference.
Just Spoke to the guy at audiotrak, hes saying its very good sound card and its apparently been tested with most of the top hi-if brands in japan considering the card is from japan from what i was told. i'm buy one, £70 price tag isnt so bad too.
It does look like it's another pro-based card, but it does state it supports the surround formats.. so maybe it will be good enough!
have you looked inot the echo gina 3g card? it has balanced outputs but you can easily make a cable to convert that to an unblanced rca. I'm really happy with mine. another option is a usb dac and an external x-over (unless your amps have internal x-overs and passthrough's) I'd also strongly look into the emu line of soundblaster cards...great great cards.
i also have an m-audio audiophile 192. it has true 24/192 and has balanced i/o (2 chan each so youd need the same equipment requirments as if you were to go with a usb dac) I'll sell it to you if you want :-)
also... there is always the pxa-h701...
could this solve your problem just get a sound card with one rca output as we all know thats a easy find then get a eq such as
because that eq only has one input per chan (main / aux) u run the one rca from the sound card to the eq which then splits the chans out to sub front and rear then just set the volume on the computer at like half or wat is best for your application then use the eq to be the main volume control
it dosent solve the mic issue but it might solve the rca output issue
This is incredibly easy.
Www.console.jp and any asio card (most pro cards) you can even add allocator for cover. Dozens of choices. You choose which RCA does what including input and draw out the path
