My equalization/room look ok?

[thxgoon]

You should be able to set the bass peak limiter 'off'.

The only 'expert' in calibrating your subwoofer level in your system is your ears.

Also, to my knowledge all MCACC receivers come with a mic. Different mics have different frequency responses, sensitivities etc.. just like any speaker does. If the system software does not know how the mic will react it has absolutely no way of knowing what is really going on in your room. It is imperative to use the included mic IMO. It's the same reason that members of this forum have gone to such great lengths to get calibration files for the spl meters we all use. They are not perfect and don't spit out accurate numbers. So we measure the response of the meters so we know exactly what is going on in our rooms.

If my bass-peak level setting goes higher than 0 does that mean it is not off? It also goes to +12.

On my Integra once the level is increased past zero/off it produces an LFE signal and it is adjusted until you do not hear audible distortion or bottoming.

here is with the bass peak level at +12. Tell me if I have been wasting my time. I'm all ready now.

I see thank you that does help allot.

My computer desk is sitting directly in front of a bass trap (has been) and there are tons of things in here for that test above also btw.

Edit: deleted my room test result.

I will order a mic from pioneer but I am not sure it is worth it since the receiver is being replaced for a HDMI 1.3 anyway. I will see if we need the equalizer for where this receiver ends up. I am not sure how it would help on the dock.

If I remember correctly they are about 20 dollars. It is worth it I think for now until May. Do you think that is worth it?

[thewire]

I had forgotten there is 24 and Lost TV seasons on DVD coming out. The mic will be ordered with no doubt. Thank you thxgoon.

Sure. Do you have any graphs of your room response to 20khz? I'd take a look at that and see how things look. To be honest if you're going to upgrading again soon and things sound good, I'd say do your best to set levels manually and use REW to see how close you are getting to a flat response. It may be that things would be fine until you upgrade, but using Pioneer's mic would be best.

I have every test saved. It can be confusing so I try to use the notes box as most often as I can. I have all the GOM attached to the frames and I am painting the trim. This is what I see so far from the other day.

Tremendous amount of noise in your impulse response. What does the impulse response look like when you measure a simple loopback cable? This will tell us if the computer is capable of a proper reading.

Always set the graphs to logarithmic - not linear.

Do a response with the sub only and the mains shut off. That way we can see if it tracks a decent target.

Always test with the receiver in stereo with no effects or surround modes on.

I will do so from now on. It was kind of difficult to figure out how. My search in the help file did not work. It was not obvious what the setting was. I read about Logarithmic in my new book.

Why the recommendation about stereo mode I am still unclear about that

[thewire]

My noise is still in the impulse response. Would that be computer hardware related still since I have switched from using the mic input to the line in input

[brucek]

Stereo mode enables only the front two mains speakers and usually with no soundfield turned on. You don't want a bunch of DSP effects upsetting the measurements..

My noise is still in the impulse response

Ensure the input levels are set correctly and use multiple long sweeps feature...

I will wait until I have a computer with no hum from the line out before I ask for any more help.
