Is there any way to revert bass management settings to their default values? My dealer changed the crossover frequency to 150Hz and I would like to try and compare what impact this really has compared to the default setting.

 

Hi Jan,

The Bass Management settings are determined based on your Speaker Types in a given Speaker Group. To force the parameters to re-calculate, I believe that you could either 

- add a dummy speaker to the group, save, then go back in and remove it

or

- delete and re-create your group

But, to be honest, I'm not certain that the first of these will work. If you want to try it out before I get back to work on Monday, please feel free and let me know if it works.

What was the thinking behind changing the crossover to 150 Hz? What speakers do you have?

If you're trying to clean up problems around the Xover frequency due (possibly) to placement, you might have better success playing with the allpass filter in the Subwoofer menu instead of changing the Xover frequency. The easiest way to adjust that is to just put on a track that you know well (I typically use a stereo track with Bass Management on and TrueImage Upmixing off for this) and, while you're listening to it, scroll slowly upwards in frequency on that allpass filter. This might be helpful.

Cheers

Geoff,

He did not explain why he made these adjustments.. The subwoofer output was raised to +3db and he changed the xover frequency to 150Hz. I have BL8000's. No rear speakers.

What subwoofer do you have? Or are you bass managing to the 8k's?

An adjustment of +/-3 dB on any speaker is not unusual to compensate for room or speaker placement.  In fact, I have never seen a setup that didn't require some level adjustment on that magnitude.

I have a BL11

I've been thinking about your options.

One possibly interesting thing to try is the following:

- Make a new speaker group with the same Speaker Types, Speaker Roles, Speaker Distances, and Speaker Levels as the one you currently have.

. Set the Bass Mangement Crossover Frequency to 120 Hz (the default for your setup)

Now, you can play with one of the two speaker groups and switch back and forth between them quickly (using Speaker + NUMBER on the remote) to compare. Adjust the one you prefer to taste.

The nice thing about this method is that you can hear where you came from and where you wound up, so you have a sort of master "undo" button.

BTW: I checked regarding my idea for resetting the bass management calculations by adding and deleting a speaker. That won't do the trick. Sorry.

FlatpanelsHD has a review coming up:

Bump!

More user experiences would be greatly appreciated. 😕

Although I'd be using it primarily as a 5.1 processor from a Comcast HD box, I'd also like to know the best way to route the output of my BM7000 through it for CD, phono and FM without loss of sound quality vs the PL output currently enjoyed from the BM7000 which is feeding 2 BL3's via a BL11 and M70's in the rear powered by an ML/MCL.

Thanks!.
