question about music

[Micha3l1985]

hi, i'm just wondering why i can watch movies at reference level with crystal clear audio and no distortion but if i try to listen to music streamed from my laptop via hdmi i cant play it at reference level, i have used mp3 gain to set them all to 89db so none of them are clipping, if i use the setting on my laptop to cut off 40hz signal from playing they don't distort but i already have the cut off on the amp set to 40hz so why should i need to turn it on the laptop as well, are the frequency settings on the amp for dolby signals only, my amp is a onkyo 609

Why can't I play mp3 from laptop at ref. level

In general music plays 10-15 db louder than movies. What type of speaker do you have with the 40Hz X/O?

I'm not one to generally mention this but in this cas eI must make an exception because it's so glaringly obvious.

Do you kow the difference between peiods and commas? ...and what a sentence is?

We get these bubble level type app for phones and mobile devices. They all have a calibrate option. If you place the device on a surface that is not level and choose to calibrate the device, your bubble level is always going to be inaccurate. This is similar to your using mp3's to calibrate your setup because your reference, the source media, is already altered from the original. Don't ever use mp3's to calibrate any sound setup. setup. Similarly, cutting off the sound at 40 Hz, is fundamentally limiting your setup. That subwoofer if placed in a corner, will definitely produce usable output down to 20 Hz.

I'm sorry to say your knowledge of how to correctly setup the system needs to be bolstered with a lot of reading and learning. The AV University section here has tons of good articles.

Couple of thoughts...

1. How are you getting your music - ripping from CDs or downloading from iTunes or other music site? If you're ripping them yourself, what program are you using? What program are you using to send the music from your computer to your Onkyo?

2. Are they mp3 files or some other format like FLAC or WAV? What bit rate are they?

You may have some limitations based on the music you're piping into your system and how it's being sent there. Typically you want a higher bit rate (320 kpbs or higher) and an accurate rip for better quality sound. You also want to use as little processing in the computer as possible (adding gain, limiting frequencies, etc.). If you're going to use processing, it's probably better to let your Onkyo take care of it, and send as clean a feed from the computer as possible.
