Yamaha Pure Direct Enabled Cuts Out Video

Hi,

Is there a way to allow video to pass through the reciever when Pure Direct is enabled? It is not a concern but I noticed that once you enable it all video out get disconnected.

This would be a real bummer for those who want to have a second video source play during Pure Direct playback. I guess it is another reason for me to keep all my HDMI and Component video connections at the TV and have the TV switch connections.

There should not be any reason why video should drop when Pure Direct is enabled.

I think Yamaha was not thinking... some day sources that have lossless encoded media will have video or pictures to be shown, just like Enhanced CDs.

Video is shut off intentionally. I assume the idea is that turning off video circuits eliminates any possible inteference from video circuits. There is no way around this that I know of.

Pure direct also turns off bass management.

Um, that's the point of the Pure Direct setting; it shuts off all audio and video circuits not being used to decrease any chance of interference in the audio path being used. Look in your manual; there's usually another setting similar to Pure but that leaves the video circuits intact. In my Onkyo's "Pure" shuts off all other circuits, "direct" leaves the video circuits operational.

Low TEch - what Yammy are you using? MY new Z7 has the ability to leave video on while in Pure Direct. Of course I would be the first to argue that it is not truly Pure Direct, but it is the next best thing to it.

I own an RX-V1800 and it shuts off the video as well just as it states in the manual.

That is funny! Video and Audio share the same HDMI cable... if noise is the issue then the source (BD player, tuner box, etc.) should switch video off on the HDMI channel not the receiver.

I guess HD fiber optic will be the choice once video can be enabled with the next generation of Pure Direct receivers.

Read your manual. I think you're missing the point of Pure Direct. It's not designed (obviously) to be used with video, just with audio, in order to get the highest-quality audio out of your receiver, i.e. when critically listening to music. As I stated, there should be another setting that keeps the video of the source on, but shuts down all other unused circuits, if you need the OSD or video for some other reason.

The noise is not introduced in the transmission (HDMI) portion, it's introduced in the processing and DAC's inside the receiver, so there's absolutely no reason for the source to shut off the video portion.

You do seem a bit confused. Don't use pure direct if you need video. That's pretty much the only advice I have for you.

Maybe in the future Yamaha will change the way it works. It's a minor feature anyway. I have tried it, and I can't say it's worth giving up bass management for.

It's going to work best if you have speakers with excellent bass response, in which case avoiding the receiver's bass management may sound better.

From my new RX-V3900's manual

"Straight Mode" can be used to remove effect processing,
but still allow video (think this is available on ALL Yamaha AVR's)



Pure Direct Mode is for Audio only ....however



...Note the * at the bottom of that last pic...
If you have an RX-V3900, and I imagine an RX-Z7
it IS possible to play Video and Audio in Pure Direct mode if you so desire

I have a turntable, no HDMI..Pure Direct for me all the time.

But you accidently do raise a good point. I'm of the thought that Pure Direct uses allows the use of analog inputs only, any of the digital inputs would not work.

Nope, the digital inputs still work.

Can you verify this? Have you tried using digital inputs in direct mode and gotten an output from the speakers?

Yes, I don't have any analog connections to the Yamaha, only digital. I still get sound in pure direct, just no video, or any processing, such as bass management crossover, etc.

Thanks. I guess Pure Direct is a bit of a misnomer then

Another confirmation here.
As I use a separate 2 channel system for stereo duties, I only use my Z7/Theatre for HT duties and video gaming. However those using a good CD player and a HT receiver such as the Yamahas should be connected via analog, and the Pure direct will improve sound quality by eliminating all non-essential circuits, and the impact they have on the signal path.

Not really, because PCM or DSD digital input are fed directly to the DACs in Pure Direct mode, so it's as pure as you can get.
