I ordered a Onkyo 674 . I read somewhere that the 674 will not decode DD+ or higher, But If My Toshiba A2 decodes the audio for me will the required 1.2 for DD+ be backward compatible with 1.1 coming out of the 674?

If not is the Yamaha 1700 is 1.2a is this what I would need for DD+ and higher Audio?

yes HDMI is backwards compatible - logically it will always use the feature set of the lower version.


specific to your query, the A2 decoding is sufficient, and you should be able to connect to the Onkyo's

So with my A2 player, The Onkyo 674 will do the job for 6.1 (In my case) set up & get at least the DD+ sound?

you'll get the sound yes but only whatever is encoded in the DD+ - if its 5.1 you probably won't be able to apply processing to get 6.1

The 5.1 is DD+ right? 6.1 is for ( My understanding is a Matrix /Neo6), But A2 puts out 5.1 DD+ true/HD via 1.1 or higher HDMI? Is the 6.1 used for DDes and DTSex?

If the 674 accepts multi-channel PCM over HDMI, that's an option you can use for either DD+ or TrueHD.


If you have issues with that you should be able to tell the player to output bistream over HDMI. It would either be DTS or Dolby Digital.

It does support PCM over HDMI, however it is limited to 5.1 as far as PCM over HDMI is concerned. Here is what owner's manual has (Page# 31)

Quote:
Supported Audio Formats (with reference to HDMI audio support)


2-channel linear PCM (32-192 kHz, 16/20/24 bit)

Multichannel linear PCM (5.1 ch, 32-96 kHz, 16/20/24 bit)

Bitstream (Dolby Digital, DTS)

Your DVD player must also support HDMI output of the above audio formats.

Thanks for clearing this up guys.

I dint sleep a wink last night because I kept thinking I would have to spend a extra $600 to get V1.2a so I would get the full audio effect.
