auto set up

[jjclecky]

hi all I have infinity primus 162 left and right fronts and primus 350 center, ps210 sub and polk rc65i in wall rear surrounds ,when I ran auto set up it calibrated all the speakers as large does this sound right? my receiver is a onkyo sr506

Common issue, the lack of proper implementation of this kind of technology by the receiver companies.

Apply cross-over. Try 80hz, and other settings if you wish. The problem was that Onkyo incorrectly assigns as large when the rolloff be found to be lower than 80hz, or at least that's how it is with MultEQ and MultEQ XT. So I presume it's an identical issue.

Even Audyssey would demand that you apply xover. As far as they are concerned, having a sub in the mix automatically means that your sats should be small.

Small vs. Large

While I'm at it, if the distances seem off, particularly the sub, just leave them be. See, the distance measurement by Audyssey is the sum of both physical AND electrical distance (filters, DSP, etc).

when doing the auto speaker setup my infinity sub (ps210) has a crossover knob, what should I set it at before I start the auto spkr calibration, also I set all my speakers to small now because my first auto setup had them at large the crossover was set at 40 should I leave it at that or change it to 80?

1. Yes, defeat if possible the xover on the sub itself. Whether it's defeatable or not, raise xover point/level to the absolute maximum (highest).

2. Try 80hz all around for starters. You can always play with it, and at least on most Onkyo receivers, you can adjust the xover point individually for all of the speakers. Depending on how small the sats are, you might raise that xover point, and depending on how capable your mains are, you might consider lowering that to something like 60hz. Regardless, 80hz all around is probably going to work just fine.

3. Report back.

HI jostenmeat, when you say defeat the xover I am not sure what that means? and also when i do the auto calib should i turn the volume of the sub up or down ? also the crossover knob on the back of the sub goes up to 150, thanks for helping me out.

HI jostenmeat, when you say defeat the xover I am not sure what that means?

A quick google didn't give me the results, or images, I wanted. I'm too lazy to dl the manual, but some subs unfortunately do not have a defeatable xover. It should be obvious, somehow. On the xover knob, it doesn't say "off" anywhere on the dial?

The best you can do, if it's not defeatable, is to have the xover point at highest. That way the "cascading crossovers" are far away as possible from each other.

Also, I suppose it's possible by using the LFE input that the xover might not even be engaged? (only for high level/speaker level I/O?).

and also when i do the auto calib should i turn the volume of the sub up or down ?

I suppose 1/3? The overall gain/volume of course is also dependent on the receiver's end too. Put receiver sub gain to zero, and sub to 1/3. If the Audysey mic can't pick up the signals, then you can raise the gain, but I really doubt you'll need to.

also the crossover knob on the back of the sub goes up to 150, thanks for helping me out.

Then 150 it is.
