I recently purchased Yamaha HTS-5560 receiver and have it connected to the JBL 6.1 speaker system (SCS160SI). I've been reading lately on other AV sites that this receiver is not really a TRUE DTS 6.1 discrete receiver. Is this something really important that I am missing? What do they mean when they say it "will automatically matrix 6.1 discrete"?
Thanks for the help in advance.
Not being familiar with that receiver, I imagine it means that it is capable of delivering 6 channels, but it only has 5 amplified channels for standard 5.1 surround. To be able to use a 6th rear center channel you would probably have to buy a mono-channel amplifier and patch it into the receiver to play the 6th speaker. Obviously you don't need to amplify the subwoofer, as I imagine you have a self-powered subwoofer.
So your Yamaha has the chipset to matrix a 6th channel, but it doesn't have the amplification to play a 6th speaker.
It is fine to omit the 6th rear center speaker and just play in 5.1---as there is rarely a "true" 6th channel in DVD anyway. The 6th channel is invariably a matrixed mix by the chipsets algorithm---it isn't a discrete 6th channel like the other 5.
G-Man, unfortunatly you are wrong, matrix means that it isnt a true discrete channel, it is mixed in with the surround channels sent through the optic./coaxial cable and then mixed out by the EX/ES decoder in the Yamaha. The 5560 does amplify the rear channel. In a discrete figuration, it has its own channel that is sent through the cable to the receiver.
I know what matrix means--read my last sentence. So it has 6 channel amplification. Okay. But does it have the newer DTS 6.1 discrete channel or a 6th channel matrix? Or does it have both?
"Is this something really important that I am missing? " No. it is hype.
