boa12 Posted January 3, 2002 Share Posted January 3, 2002 i was just thinking (look out ) on my future conversion to HT in the 2nd room. i've got this vintage kenwood stereo receiver & marantz sr8000 back there. but the sr8000 is just 5.1 max decoding & hook-ups. so whenever i do get the added speakers, why not just run the sr8000 2 rear preouts to the big ken's aux inputs & switch it to mono. then attach 1 or 2 speakers to it for rear surround. should give a similar rear surround matrixed effect as ex or es. seen some doing this w/ a prologic receiver, but a stereo reciver in mono should work pretty much the same. just wanted to bring this up for possible problems &/or info purposes. i'm a long way off from doing it (I hope for $ sake ). though after reading about dolby digital EX @ www.dolby.com realize i wouldn't get the same effect as EX encoded material & a processor w/ dolby EX decoding. here a seperate 6th channel matrixed from info on the surround channels is actually encoded/decoded. imagine the same would hold true for DTS 6.1 ES encoding & decoding. ------------------ My Home Systems Page This message has been edited by boa12 on 01-03-2002 at 11:01 PM Quote Link to comment Share on other sites More sharing options...
Seb Posted January 4, 2002 Share Posted January 4, 2002 If I'm reading your description correctly, it wouldn't work. The prologic receiver will take the stereo rear signal and decode a matrixed signal for the rear center, taking (that's my understanding at least) ONLY the sounds that are recorded at the same level left and right and putting them in the middle. What your setup would achieve is take ALL the info from the stereo rear signal and transform it into a common rear center. It's completely different from matrixing, as matrixing extracts the relevant info while you'd just be taking all of it and putting it in the middle (in addition to the left and right). Correct me if I'm wrong guys! Quote Link to comment Share on other sites More sharing options...
boa12 Posted January 5, 2002 Author Share Posted January 5, 2002 good point seb! prologic does extract just the mono info from a stereo signal to form a center channel. yea w/ a stereo receiver in mono here it would sum together all the discrete RL & RR channel info w/ 5.1 material. that could take away from the directionality effects of discrete RL & RR channels. though it shouldn't be any dif w/ prologic material, wouldn't want that on dolby dig 5.1 or dts stuff. well then guess i'd use the sony de935 for that & move the big ken to the bedroom. thanks! ------------------ My Home Systems Page Quote Link to comment Share on other sites More sharing options...
ShapeShifter Posted January 5, 2002 Share Posted January 5, 2002 Yea, good point indeed! As I overlooked the switching to mono statement. However, if the Kenwood or Sony has L/R main ins, you could connect marantz pre-outs which would pass the surround decoded signals to L/R main ins of Ken or Sony which would power the added speakers. That would be similar to what I'm doing with outboard stereo amps. The decoded surround signals for my additional fronts & rears are passed to the additional amps for those speakers. Think this would work, depending on the capabilities of your Kenwood and Sony receivers. Hopefully I understand what want to accomplish!
