Yamaha RXV-640 DTS problem

[jamesb]

I have just entered the home cinema 'club' with the purchase of Yamaha's new rxv-640 unit, a few days ago.

Its connected to a B&W main speakers, a Gale centre and (temporarily) a set of cheapo rears. The DVD source is a Playstation 2, connected to the amp via optical cable. Not ideal, but should do the job til I can afford a dedicated unit.



My problem is this:

I doesn't matter what source DVD I play (DTS, Dolby Digital etc), the amp only ever displays Neo:6 on the screen. I am getting sound out of all 5 speakers, but no 'proper' descrete decoding. Also, the LCD screen only shows a graphic of the left and right speakers, not the 5 that I have preconfigured.

If I try to force the amp into DTS decode mode, I get no sound at all. Before anyone asks, I have set the options on the DVD to DTS.



I've assumed that I should be seeing DTS on the LCD to be getting best quality decoding?



If anyone out there has had a similar problem with a Yamaha or other amp, or if anyone can suggest anything to try to fix this (I may well be making some schoolboy error, being new to the game!), I would be VERY grateful.



Is it worth trying another optical cable?



Cheers in advance,

James

Before anyone asks, I have set the options on the DVD to DTS.


But have you told the PS2 to output DTS? It is almost always disabled by default.

I've been into the PS2 configuration menu, and the only option you have is to enable the optical out, which I have done. Unless I'm looking in the wrong place, there doesn't seem to be an option to define what type of digital signal the PS2 sends down the optical cable.

I'm not familiar with the PS2 menus unfortunately. If there is no option then maybe you do need to try another cable. I presume the amp has the DVD input configured to the optical socket?

Sorted it!!

It was a (not obvious at all) setup menu that can be accessed while a DVD is playing. From here you can enable or disable a number of options including DTS and DD.

These were both turned OFF on my unit. Good job I found it before sending the Amp back to Yamaha- could have been embarassing!!!



Cheers anyway,

James

Thought it was a bit odd you saying there was no option. Glad it's sorted now :)~:-)~:smile:
