It's called a DSP or Digital Signal Processor.
OPTICAL INPUT TO RCA OUTPUT CONVERTERS!
Ok . I know alot of people are having issues regarding RCA jacks and their amps. I know some people have blown out their systems out that way. So I wanted to keep my head unit. I wanted to know if there is an optical to RCA converter. So that I may go from carputer .. through optical output. . to a converter... to RCA signal .. to car in dash head unit. .. and then out to amps and system...
p.s. are there any sound cards that do this?
would this work?
again im looking for optical to RCA adapter/ converter.
Now ive seen the DSPs but they are a bit pricey. So I would love to maybe not mess with one. but wont hesitate if I have to.
By the way im planning on getting a headunit instead of going the carputer by iitself. and im leaning towards an alpine cd/mp3 player with AUX input in the back. 4.1 system in the car.. nothing special .. just simple
That's just another sound card, man....Originally Posted by Crazystick
Sure, you could run your optical out from the motherboard into the Creative unit... But why would you? That's completely pointless.
Now, the Creative USB sound device is likely to provide better audio quality than your onboard sound...
The SPDIF out needs to feed into a digital signal processor to process that digital signal into an audio signal. Yes, DSPs are pricey. I can't do a damn thing about that.
I don't mean to bag on you or your plans, but it appears that you don't have any understanding at all about audio signals. I suggest you do some research on that before you progress. You'll save yourself time, money and countless ulcers.
Digital is expensive. A good DSP that can take output from anything, not just proprietary hardware like CD changers, can run you $300+ easily.
Take a 3.5" Minijack to dual RCA cable, and run it to your headunit's Aux In. PC soundcard outputs are very, very weak. I'd be amazed to see one blow a headunit. A DSP *is* a digital to RCA converter.
A cable might cost you $10, a digital setup could easily cost you $300 onwards. The only major advantages of digital are amazing signal quality and surround sound capability. Unless you're going for a full 5.1 surround sound audiophile-quality system, it's way overrated.

This man needs an outboard d/a converter. they can be had for about $50 to $900. lots to choose from.
Ok yes I do know a bit about audio signals. I used to work at a car shop installing tvs and vcrs.. dvd players.. and what not. I know some people go the crappy way of installing a rf modulator and thats what we would do @ the shop. But always hated the quality. Hence that isnt going to happen in my setup.Originally Posted by DarquePervert
Ive yet to buy any parts and all I have is 1 4 channel amp. It will power my highs and a pair of 6 x9's. and have another amp for one sub.
Sound quality. In my experience with indoor speakers. I know that the 3.5" Minijack carries audio output. But what most people fail to understand is that it also carries a voltage with it(duh all signals do) and thats how you control the audio level on your headphones.Controlled through windows volume setting or whatever OS your running. But with certain indoor speakers Ive managed to have blown out a pair already. Alot of people here in these forums have issues with that and how their setups dont work anymore. How did this happen?
The higher the volume set on your computer, the higher voltage(signal) going to your speaker(s) setup. So when the signal is amplified with the Its own speaker volume control, It tends not to be friendly on your setup.
Which brings us to RCA's.
RCA's dont carry extra unnessary voltage like the headphone jacks. Hence if I am to go with an easy carputer setup like a ..carputer >> headphonejack to rca adapter >> into my Head unit. I am assuming the same situation would occur where the HeadUnit is taking in excessive Voltage and the amps in turn would not be friendly to my speakers. And that is why I require a converter from optical to RCA. I think that would be to be on the safe side of things.
The Only reason I want a DSP is that people seem to preach it but I think I could go without it. And again I am trying to avoid the excessive voltage into my headunit. So I am looking for an optical signal converter to RCA signal. Has anyone seen that or can They post something that would help guide me and maybe others .And I would as many here would appreciate a fair technical answer and not opinion. thanks
"RCA's dont carry extra unnessary voltage like the headphone jacks."
This is completly untrue, in fact that entire paragraph is misguided. Most people are concerned with the audio signal not being high enough for their amps, not the other way around.
