Phase check

[Wull]

Been running some sweeps and I get the feeling my centre speaker could be out of phase. What would be the best way to check this please?

Make full range measurements, not measurements stopping at 1 kHz, and look at the polarity of the impulse responses with the % scale.

Hi John.

How do I set impulse to this scale (2.00ms)?

Thanks John. I did know that, just wasn't sure how to set it to 320u/2.0ms. Think I'm OK with the settings I have.
