After measurements, Dirac Live introduces a delay in left channel. But I do not need it, how to turn it off?

Hello Dmitry

That delay would be calculated based on making your L&R time aligned. Unfortunately you can't turn it off (embedded into Dirac Live tuning algorithm). Sometimes it's related to the position where the first measurement is made.

In the PC version, such a button was here.

UNfortunately the PC and miniDSP version we get from Dirac Research are different I'm afraid.. :-( We don't have control of any of these settings once Dirac generates a filter for us.

Is this option unavailable still? I emailed Dirac live support and they said this is a miniDSP issue and out of their control. I find that hard to believe since they provide the software, but I will ask here first before I reply to them.

@JasonFoi

Ability to bypass all the gain + delay settings made by Dirac is indeed not something supported in our firmware/DSP structure I'm afraid. It would require a modification of quite few things to make this happen (ie.. new GUI, new firwmare commands to bypass whatever changes Dirac is asking). I don't believe that other Dirac Live DSP unit (not the PC versions you're point here but an actually Dirac live DSP) does this now. Are you aware of this?

Quite useful to us would be to understand why you'd want to turn off time/delay alignment. It's key to a properly tuned system.

Any delay between the two channels will Comb Filter like crazy when we Monitor in Mono.

The second case is more difficult to explain. In highly treated rooms the delay is easily heard and rejected. I believe this may be because the summing of the mono component of a stereo programme is very 'clean'. i.e. somewhat similar to the electronic or DSP summing. Typically say 85% of the energy in a stereo signal is mono. The comb filtering from the delay is aweful and makes the minidsp unit useless for professional monitoring.
