    Hi Volt heads are great if you need them. Problem is - 2V heads work just fine if your downstream equipment is any good.
    sorry to ask so many questions; but say we're going s/pdif into the behringer... what's the output voltage? I'm not overly worried about it since my amps have balanced inputs so induced noise is less of an issue for me, but it would be good to know

    Ah geez. Right. That's like talking about Jesus in a Buddist temple. Or the Browns in Cincinnati. Whoops.

    So, you guys could help me with the in car computer stuff? My closest connection for this was building a, "biscuit PC" power supply (before they were plentiful) back in 1998 for my brother's MP3 player he built for his ride. His rig of a power inverter was unreliable and he always forgot to turn it off. I built the supply on a piece of perfboard and rewound the transformer from an old car amp. It was a little electrically noisy, but worked fine.

    He then bought the indash eMPEG Rio(?). I think he still uses that...

    Uh, that would be as high as you want. To around 9VRMS before clipping. Way overkill if you ask me.

    on a different note...you will only have the voltage out that you put in...so say I go with the Hippo HiFi USB DAC...which only has something like .5v output...means I'll only have .5v out to of the Behringer to the amps, correct?
    If your amp can accept a 0.5V input with acceptably low noise, then there is no problem. You can increase output gain of the Behringer somewhat, but at the expense of noise. I'd build (or buy) a high end preamp before the Behringer is there was a significant problem.
    It's only 0.5VRMS Max? That is lower than line-level.

    well, a quick search tells me it's actually 4.1v but I'm double checking that right now.

    hmm.. well what is the best way to figure out the best out how to set your gains. do you set the behringer close to 9v but not clipping and set the amp's gain low, or do we set the behringer low and turn the amps gain up?

    I would set it to where you can set the amps at the lowest gain. This will allow the amps to run most efficiently.

    I would agree with you but i'm just wondering if the gaining at the amp would be cleaner since the amp is built to much higher standards then the dcx (i am assuming here)

    i guess i'll just have to test it
