Sujet Using 2 USB sound cards?

This might be a 101 question.

I'm not happy with the audio quality coming out of my aging Denon DN-HC4500 controller. It has a dual sound card built in.

I'm thinking of trying 2 cheap USB sound cards before investing in a newer controller.

Is it possible or safe to run 2 different USB sound cards and an external mixer? Deck 1, USB 1, Deck 2, USB 2?

The audio I'm getting now sounds distorted, like 128k bit rate or an old cassette tape that has degraded or stretched slightly. I use OTS for dinner music connected directly to the mixer, sounds perfect. It's the Denon sound cards (unless I have two cooked channels on my mixer, which I only just thought of).

If you're not happy with the quality from your HC4500 then I suggest you should not be considering anything "cheap".

It's also not advisable to run two different audio interfaces. Buy just one that has the required number of outputs.


Before doing anything else though, test the 4500 with a different computer, different mixer (or different inputs), different USB cable and so on.

Thanks! "Cheap" was what I wanted to buy to test my theory, rather than spend hundreds on a real sound card to find there's no improvement.

I had the system set up and running for 24hrs straight and can't get the problem to happen here at home. I recently changed the way I set my system up, and I have a feeling part of my facade and other methods of making it "pretty" have inadvertently blocked part of the laptop venting. Not so much it shuts down, but enough to affect the audio.

More testing.

As for the 2 interfaces, maybe I do have a problem there. VDJ is running through the Denon controller and utilizing ASIO. But I also have OTS AV for dinner music early in the night and it uses the Stanton DJ mixer's built-in USB sound card. So while each program has its own sound card, the laptop itself can see 2 sound cards. I'm using external USB hubs (powered) too. Could this be a problem?

You can use 2 different sound cards at once with VDJ.

I do it all the time with no problems, just try to match the sample rates and you should be good.

I use a Pioneer DJM 850 and a cheap little Behringer U-Control UCA200 for recording.

I do have a USB MAYA 44 I could test out as well with timecodes if you'd like but I really don't think you'll have problems in my personal opinion.
