TOPIC:

Hi all. I'm a noob to Dirac/miniDSP and have some questions. First post here, so please go easy

1) My frequency response features some dips that can't be fixed by EQ (modal and comb filter nulls). Should I customise the target curve in Dirac to follow the shape of these nulls, so that the software doesn't try to boost them unnecessarily?

2) I'm using the DDRC-22A (analogue in/out). The -10dB attenuation messes with the gain staging of my set up, resulting in a low output to my powered monitors. Would I be ok selecting the -6dB attenuation, given that one of the frequency dips that Dirac tries to correct is just over 10dB? I don't want to eat up all my headroom and cause clipping. But equally, I could really do with the extra output level.

3) Is there an option to switch off the inter-speaker location correction delay?

Thanks for any advice!

Good question.
- Typically we'd always recommend to keep the target curve around/below the overall natural response of the speaker. Trying to follow DIP isn't required though. Dirac Live algo will know better when he sees a huge DIP.
- Sure, I don't think that any problem to remove the attenuation. You should be all fine.
- No control of the delay I'm afraid. It's preset by Dirac Live.

Thanks Devs!

- I've since tested using a target curve that follows the dips and a curve that doesn't. No audible difference; nor any significant visible difference in acoustic measurements between the two curves. So I'm going to leave the target curve not following the dips for convenience.

- No sign yet of any clipping using attenuation set to -6dB (rather than -10dB), so that's all good.

- Shame about no option to control the inter-speaker correction delay. That's pretty much a deal breaker for some of my professional colleagues. Perhaps something to discuss with the team at Dirac?

Thanks again for your reply.
