Analog inputs and bass management

[PSU80]

If I want a 2.1 output and use the stereo analog inputs of my receiver, will the signal remain in the analog domain or will my receiver convert it to digital to perform base management? For example, if I wanted to use an Oppo 95 or turntable as an analog source I don't think it would make sense if the signal had to be converted to digital first to send output to the sub. My receiver is a Yamaha RX-V2400 if that matters.

Thanks

The analog inputs bypass any digital bass management. That must be handles in the source. If the source has nosubwoofer output, the your subwoofer won't work. But the plus side is that as far as the receiver is conderned, the speakers will be seen as "large". ...unless the source can over-ride this.

Not correct.

This only applies to m/c inputs.

In 2-ch stereo, the x-over is employed provided the mains are set to SMALL.

True. I interperted this as referring to the multi-channel inputs such as one might use for Blu-Ray players. I ran into this situation myself recently.

For the "regular" inputs that go through the total preamp section, you are correct, although I think the sub is still disabled if he chooses the "pure direct"* mode.

*or whatever it's called.

As for bass management, it should only be employed in one device.

EDIT: Unless utilizing a BR players analog m/c outputs.

In other words, anything utilizing the receivers m/c inputs should have the bass management set internally.

 

[zumbo]

STRAIGHT will leave it in 2-channel without x-over and sub.

When using MC inputs it can ONLY be employed in the source.

Edited previous post to be clear!

Too Late!

At least we're both on the same team. Let's hope OP got the answer to his question.

Not actually. I was editing while you were posting.

Then, I added my reply.

At least the OP is getting some good information.

OK, so if I use the stereo analog outputs of a source device and the stereo analog inputs of my receiver I'll be able to get 2.1 while remaining analog the whole way?

No. If you choose to go pure analog you lose the subwoofer. You only get the subwoofer if the signal goes into the digital domain. Z stated this in post 6

The only way to get pure analog is to conciously choose to NOT go into the digital domain is to choose "pure direct", "straight", "analog bypass" or whatever your receiver offers to accomplish this. You will have pure analog, but no subwoofer. Check your manual for more.

That's what thought but I wasn't sure. That being the case, I guess it doesn't make much sense to spend the extra $$$ to get the Oppo 95 and the upgraded analog stage unless you're running full range speakers.

For blu-ray, the audio output would be up to the engineer which I would assume would follow the industry standard of sending below 80 to the LFE.

Correct?

The BR would be using the m/c inputs on the receiver, and would not be utilizing the receivers bass management.

If you were to use this player for 2-channel music wanting to utilize the receivers bass management, just make a digital connection to the receivers cd input. When using a cd in the unit, select cd on the receiver.

Look, the multi-channel inputs are totally different than plugging a red/white analog signal into CD or aux input.

For one thing, the former have provisions for a 5.1 (or more) channels while the latter only support two-channel stereo. Also, the former bypass everything except the volume control so they stay pretty much analog throughout.All the fine tuning is done in the source unit (Blu-ray player)

The latter presume you want the full range of goodies (including a subwoofer) so they default to a brief trip through the digital domain for this and other goodies, like tone controls, etc. You have to consciously defeat these if you don't want them.

This is the big difference that Zumbo and I went round and round about. I would hope you've got the distinction between them by now. You might want to spend a little more time with your receivers manual.

I tried the analog work around for my previous Yamaha avr, and finally bit the bullet and faced the HDMI fact for my ht.

I have since decided to build a separate pure analog rig, which is what I am working on now.

My ancient, coal-powered receiver lacks HDMI and, conversly, has no provision for decoding the hi-glitz audio formats Blu-Ray offers so, if I choose to avail myself of them (and I do), I use my analog 5.1 mc inputs.

Markw, I understand the difference between the MC inputs and stereo inputs and don't need to be lectured about spending more time with my manual. The manual doesn't specifically address my question or I wouldn't have asked. I was considering spending more for the Oppo 95 specifically for the upgraded analog stereo capability. If the signal gets converted back to digital no matter how briefly than it seems the limiting factor would be the dacs in the receiver unless I'm missing something.

I don't believe there was any disrespect meant. We are all here to learn. I have learned from your thread.

And it does seem that you have missed something. A re-read of the thread may help.

You do not need a separate system for 2.1.

You need a switch to go from the receiver pre/pro crossover to external analog crossover. It means a DIY solution, bit it works well.

If you are in this hobby don't expect to get everything off the shelf. Customizing means designing and building some of your own gear.
