  1. Hi all, I’m new here and was hoping for some advice. Convinced myself I want to run a 4.0 system for movies. I currently have a 2 channel system I am very happy with for music and ok with for movies. I’d like a better set up for movies and it seems many releases are dropping 2.0. My 2 channel is Lenehan ML2+Rs, older Metaxas reference power amp and a borrowed lower end DAC/pre. This is more than enough to shake my wife’s couch in the lounge above my man cave. I have double layer 16mm gyprock ceiling, a 450mm air gap with tontine and wooden floor on 450mm joists between us. I don’t feel the need for a sub. The system pumps it out down to usual sub frequencies, down a bit at 20Hz but still tight and adequate. My 2 channel system smashes in imaging, attack and low end than the same set up with a lenehan centre speaker and a Yamaha RXA 2030 AV amp. The Yamaha does a bad job of downmixing to 3.0 or 2.0. My panasonic TV does a much better job than the Yamaha and when required I’m using the TV to down mix movies to 2.0 then sending out through my 2 channel system. Mates have been impressed with the quality of my centre speaker when running stereo and they get a bit confused when they see it’s not plugged in. Tried using the Yamaha just as a preamp for the Metaxas and still not great, almost worse. The Yamaha as a pre or integrated amp for music also is not that good compared to my 2 channel system. Matching my 2 channel set up for 5.1 etc is really expensive. And I don’t see the need in my 7m by 4.5m room to run a large number of speakers for surround, especially given how happy I am with stereo. I’d instead like to duplicate my stereo system but with a lower end amp for the rears. Where I’m struggling is finding a processor to convert to 4.0? It seems there may be processor/pre AV units out there but seems over the top given I only need 4 of the 11 channels they pump out. And I’d probably prefer to buy better stereo DAC/preamps for the budget.
  2. Hi, joined to go over some old/archived posts for info to correctly re-wire speakers to suit a low-powered retro 1970s pre-Optonica Sharp 4 channel Radiogram GS-9200 ($40 got me a working unit with ye olde speaker connections & two Sanyo 3-way speakers, so no speaker cables/ plugs that fit). Rear speaker connections take a plug with two (different sized) prongs - not your standard DIN plug but probably not too hard to mock something up to fit. I have sourced some Sharp Golden Sound speakers with no plugs which I figure have low enough power ratings to use as Rear speakers. Front speaker connections takes a plug with four prongs, three active for 3 leads to speaker box, I think the 1st to high (+), 2nd to low (+), 3rd to common (-). Basically, I need to sus out what is needed for crossover, re-wire as needed and replace speakers in Sanyo boxes with lower-rated speakers to suit the Sharp receiver). A bit tricky without service manual or even operating instructions and HiFiManuals.com etc has nothing for these (now 40 year old) 4 channel receivers that were built on the cheap for the Australian mid-fi market that existed at the time... Some previous forum postings have images, schematics for other Sharp models, and identify similar issues: At Stereonet: http://www.stereo.net.au/forums/index.php?/topic/36535-help-with-dads-old-hifi-connecting-to-his-amp/ See also QuadraphonicQuad: http://www.quadraphonicquad.com/forums/showthread.php?17126-Sharp-Optonica-GS-4520A-Speaker-Connections And Audiokarma: http://www.audiokarma.org/forums/archive/index.php/t-268190.html
  3. Hi all, Just recently I came across an ad on Gumtree, For sale was an old jvc system with 4 speakers, no pictures, that's it. Went to investigate, and what i found was quite something. The system is from the 70's i believe, consists of: JVC 4VR-5436X Fm-Am 4 Channel Stereo Receiver with built in CD-4 Demodulator (Quadraphonic) - http://www.thevintageknob.org/jvc-4VR5436.html JVC SK-12 4 Way 6 speaker boxes with wood lattice - pair JVC VS-5399 Bi-directional rear speakers - pair - http://www.thevintageknob.org/jvc-VS-5399.html A woman was selling it, i don't think she realised what she was selling. All she wanted was $20!!!!!!!!!! SOLD All the pieces are in fantastic, original condition, and the receiver works beautifully. The SK-12's are unbelievable for something from the 70's! Does anyone know what the REAL resale value of this system is? Thanks
