Reference Level Audio: Some questions.. (1 Viewer)

[Brett DiMichele]

Ok I hear people refer to listening to music and movies at
"Reference Level" and my question is: Is Reference Level the
same on all high end Receivers? For example my Onkyo DS787
states Ref @ 62 (If I am not mistaken) and the volume scale
goes past Ref to 70ish or so.
Ok another thing is Ref is @ 62 is this acheived with all
the channels set to a flat 0Db (L/C/R/SL/SR/SB) ? How would
a feature like "Intellivolume" factor into the equasion?
Since the Onk has this feature and it is adjustable from
-12Db to +12DB.
I am just curious that's all. Is Ref a certain Db like say
100Db? If so then I guess I would need to "Set" Ref using
a Rat Shack SPL Meter to ensure that Ref is accurate?
All I know is at Ref with all channels set to flat 0Db it's
LOUD as heck and it goes anoter 10db past that..

Yes. Reference level is a setting that will yield 105dB peaks at the listening position for all channels except the LFE which should be at 115dB. If you set all of your channels with Video Essentials for example, they are recorded -30dB from peak so you set the SPL meter at 70dB and try to get all of the channels(including sub) to 75dB(the +10dB on the LFE is done on the soundtrack and not by the user). Some people like to set the sub +3 to +6 dB however.

Bhagi,
That is exactly what I thought. Thanks for the reply!
Now all I need to do is get an SPL meter and some test
disks

Does anyone know what the Avia test tones are recorded at?
Thanks,
Russ

I believe Avia is recorded at 85.

Does Avia have signals for the two back surrounds? My VE disk only has the side surrounds.

 

[John Kotches]

More correctly, Avia is recorded at -20dBFS, which is 20dB below Full Scale signal.
