Turning Power down causes distortion in bass
« on: December 22, 2016, 10:41:14 AM »
Hi,

I've recently purchased a new pair of Beyerdynamic DT770's (80ohm) in combination with a Creative Sound Blaster Z soundcard. The sound is phenomenal but BAE still 'enhances' the sound, especially on bad recordings. I've set up an EQ on my soundcard with the pre-amp turned down (as to minimise the possibility of distortion).

What I've noticed, though, is that in some bass-heavy cases, there is a slight crackle. I've fiddled around with my setup a bit and I've found out that the crackle disappears when I turn up Power or deactivate BAE altogether. I have Power set to 35, Range to 30, Speed to 25, Bass to Normal and Bass Shape to -20. Noise Reduction is also turned on, all other settings like buffer and sample rate are default, changing them doesn't improve anything.

A good example on where there is a lot of crackle is during the first 10 seconds of this song: https://www.youtube.com/watch?v=8ClTE1Jf5HI. It seems like it's the sub-bass that causes it, though it doesn't always occur when there is a lot of it. Is there anything, aside from turning up the Power to max, I could try to remedy this?

Thanks,

Reed

Are you using ASIO drivers? If so, you might need to increase your block size slightly. The "crackle" could be when the buffer just runs out before the next one refills it.

Not as far as I know. Is it something I should try out?

I haven't been able to find anything to increase the buffer time.

Disable all of the soundcard's effects/EQs/etc... then see if the distortion is still happening while fiddling with Breakaway's "power" slider on whatever preset you're using... also try changing the loudness you're hearing in your headphones, to see if it's just the headphones blasting too loud or some other kind of mechanical noise in the headphones.

If there's no distortion from all of that testing, then it's (what i expect) your soundcard's effects/EQ/etc causing it.
