Five channels level setup

[Humberto]

I own a HTIB from Pioneer. The receiver is a VSX-D414 and I'm pleased with the whole system.

My inquire:

The remote control gives me the possibility of choosing the level (-10db / +10db) from each of the 5 channels (default is 0db). What's the best setup for the channels? Should I leave them at 0db?

Also, it happened a weird fact.
I used to have all the channels in +10db; but after setting them back to 0db and watching a 5.1 DVD I noticed the ones had the following parameter:

- Front Speakers (L and R): 0db
- Center Speaker: -1.0db
- Surround Speakers (L and R): -3.5db
- Subwoofer: 0db

As I had not made any change, should I wonder that's an automatic setup for Dolby Digital and DTS audio?

I do appreciate some feedback.

Regards!

The only way to properly adjust the levels manually is with a SPL (sound pressure level) meter, which can be picked up at Radio Shack for about $40. I can't find any specs on that model. Do you see MCACC anywhere on the receiver? If you did not actually run this function, then there is no reason why the receiver would change those settings. My guess is this model does not have MCACC, but since I can't find anything on it, I can't be sure.

Speaker level calibration

Humberto,
First, don't adjust all speaker levels to +10 db. Either leave them at 0 dB or perform a manual or automatic calibration. The speaker level calibration allows sound effect that travel arround the room to maintain the same volume level relative to the listener. Otherwise, it might be loud in front channels, quite in center, loud in surrounds, etc.

If you receiver has an autiocalibration mode, use it.

For manual calibration, most receivers will output a test tone to each channel to allow users to adjust the speaker level. Leave the mains at 0 dB and adjust the other channels so that the volume level is the same from you primary listening position. The best way is to use a Radio Shack type SPL meter, but by ear you will get within a couple dB.
Most receivers also allow you to specify the distance from each speaker to the listening position. Use a tape measure and enter the distances.

Now you are setup properly for the Dolby Digital and DTS soundtracks on your DVDs.

Hi guys

Thanks a lot for your suggestions. It was really useful.

For sure my receiver doesn't have autocalibration!
