Volume control on a Yamaha RX-V1800

[3db]

I find that I have to turn the voume up to around -28db to get a comfortable loudness level whne listening to vinyl. It takes many turns of teh volume control to see the loudness bar on the menu to increment. Once the loudness bars reach about halfway, the increments become much bigger. On my old Technics, there was no graduated type of volume control. It seemed more linear or is that logrythmic

I've noticed the same on my HTR6190B...about halfway through before anything really happens and then each step is more noticable. It personally doesn't bother me though.

It’s exponential! Every 1 db increases the power by about 26%. So each time you increase the volume by 1 db, the absolute power change increases.

db Increase_____Pwr Output(W)_____Pwr Change

1______________1.260______________0.260
2______________1.588 ______________0.328
3______________2.000 ______________0.413
4______________2.520 ______________0.520
5______________3.176 ______________0.655
6______________4.002 ______________0.826
7______________5.042 ______________1.040
8______________6.353 ______________1.311
9______________8.005 ______________1.652
10____________10.086 ______________2.081

So you can see that a 3dB increase doubles the output and a 10dB change increases the output ten fold.

Sorry for hijacking these thread, I own a Yamaha RX-V1800. Just got myself a Sony 350 bd player. Hook it up to the rx-v1800. Play a bd with truhd track. The truhd 5.1(L,C,R, SL & SR) lit up on the front panel display. Play a dts hdma 5.1 track, All channel(7.1 channel) lit up on the front panel display. I just want to know where went wrong.

Having viewed both 7.1 and 5.1 DTS HD-MA discs, I have noticed that to. I figured it was dependent on the actual disc and whether they're 5.1 or 7.1? Besides all 7.1 tracks will be downmixed to 5.1 anyways, if that is your chosen set up.

Those speaker icons on the front panel only indicate the source material, not what the amp is drivng. So in tuhd, the signal only contained 5.1 version of im\nformation as opposed to its dts hdma counterpart. I fins this bizarre personally that there would be a discrepeancey of teh number of channels used between the 2 formats. Its the disc, not the RX-V1800, nor is it the player.

Yeah! I do agree that those speaker icons on the front panel display only indicate the source material. If the source is a dts-hdma 5.1 track, shouldn't it be only 5.1 channels and not 7.1 channels, right?

What I'm saying is that maybe the DTS soundtrack is 7.1, the Dolby 5.1. I kinda find that weird myself.

I tried 2 bd titles. There are Die Another Day and Kiss Of The Dragon. Both of these titles stated they carry dts-hdma 5.1 tracks behind their respective boxes. I, too find it weird a 5.1 tracks can become a 7.1 track.

 

[Nomo]

I can't say I'm at all familiar with the Sony player, but is it possible it's matrixing the 5.1 into 7.1?
Is the player set to bitstream or PCM?

You didn't do anything wrong, it's a real bug in the receiver. All 5.1 DTS-HD MA and DTS-HD HR bitstreams light up 7.1 indicators on the front panel. The good news is the bug only affects the front panel display. If you check signal info it correctly says 5.1, and PLIIx can be used as normal to give you 7.1 output. TrueHD bitstreams don't have the problem.

Thanks for the info. Yeah! There is no audio from the two surround back speakers eventhough all 7.1 indicators lit up when playing a dts-hdma 5.1 tracks. I was relieve to hear that the bug only affect the front panel and not the audio. You are right. My Sony bd player said it is 5.1 signal. Have hear you any remedy for these fault?

I never asked Yamaha about it, but I don't think they would make a firmware fix just for that. I have PLIIx set to come on automatically for 5.1 tracks and it works fine and gives me sound from the rear speakers as normal, despite the incorrect channel indicators. So this particular bug doesn't really bother me.

 

[shenaniganz]

So back to the OP. Is it normal to turn the nob alot befor you get any audio?

 

[AVRat]

Generally, yes. If the receiver is set up properly, you should start getting decent output from -40 db and up. Maybe even -45 db and up. Obviously, room size and speakers' capabilities need to be taken into account.

OK, on topic...

For me the key is to look at the actual volume number (which is dB relative to reference), rather than the volume bar. The volume bar is practically useless. So when you need to turn it up or down you have in mind the approximate number of dB you need to change (e.g. you want 10dB louder, or 5dB quieter, etc.). Then you can get there rapidly without overshooting (because you start slowing down when you're approaching the target volume).

Other people with programmable remotes have programmed the IR codes for the receiver's volume memories, so they can go straight to their most commonly used listening levels with a single button press.
