Yamaha Receiver Owners, Help!

While setting my Yamaha receiver, I came across Dolby DGTL Set LFE Level (range: -20db to 0db) and DTS Set LFE Level(-10db to 10 db). What are they and how do you set them? They're both currentl set at default: 0db.

You can set the .1 LFE channel seperately. I believe I have my DD set at 0 and my DTS set at 6.

Still don't get it.

You've gotta excuse me for my stupidity. I still don't understand. Unless you mean it's like a volume setting for your subwoofer, in which case I don't have one. Is my conjecture correct? And if that is the case, why 0 for DD and 6 for DTS?

Not a volume setting per se but a level setting.

I would check your owner manual for a description of the procedure.

The difference between DD and DTS has to do with the was the soundtrack is mastered.

I did check my user's manual

However, it just gave a brief description, something like, "it's for adjusting the level of the Dolby Digital LFE level." Duh! Excuse me, circular definition!
Again, if it pertains to adjusting the level of a subwoofer, then I don't have one and I won't bother worrying about it.
JimRochester, by the way, how did you arrive at the values that you've chosen for yours?

If you do not have a sub then you would not have to worry about it, correct. The LFE is a seperate channel, hence the .1 in 5.1.

One thing you do have to worry about if you don't have a sub is making sure your LFE is sent to the main speakers. I have a different Yammy than you (mine's non-DTS) and it has an "LFE Out" on the menu that you set to sub or main. Make sure your's is set to main or you won't hear any of the lowest bass.

LFE (DD & DTS) Trim Level controls are used to REF Calibrate the level with the rest of the HT Speakers (Front/Center/Surrounds)

Simple explaination, ...

The following is for my Yamaha RX-V995 - NOTE: Your results/process may differ:

DD LFE Control Range: 0 to -20
DTS LFE Control Range: -10 to +10
All Speakers = SMALL
Yamaha x-over = 90 Hz (fixed)

Using Video Essentials DVD:

1) REF Calibrate your HT Speakers (F/C/S) = 75 dB
....a) RS Analog SPL Meter: Dial = 70 / Speed = SLOW / Weight = C
....b) My REF Calibration Volume Control Position = 12 o'clock high (#16)

2) The last test signal is a dedicated LFE Signal (for DD) adjust = 75 dB (or 4-6 dB higher depending on you sub impact preference)
....a) If you want to REF Calibrate 4 - 6 dB hotter, change the RS SPL Meter Dial = 80

3) Note the Level # you used to establish your DD LFE REF Level and add 10 for your DTS LFE
....a) My example:

DD LFE = -4 (@ 77 dB - lowest needle swing = 75 dB / highest = 79 dB)
DTS LFE = +6 (just add 10 to -4; -4 + 10 = +6)

See my more detailed process here.

NOTE: Because my website is 'free', hosted by GeoCities, if too many HT enthusiasts visit, GeoCities will shut it down for an hour or so because it exceeded the specified 'freebie' Data Transfer Rate. Sorry about that, just bookmark it and visit my site an hour later or when everyone has gone to bed!
