Yep.it was. The issue in them there days (pushing 20 years now) was that the potential sources for a home theatre system were Sky boxes, DVD players, Video Tape Recorders, Games Consoles, Analogue TV tuners etc. and they all had different audio outputs: digital SPDIF coax, optical, and analogue RCA. HDMI was in its infancy, I think we had one of the first HDMI DVD/TV setups. It was a 50" Pioneer Plasma TV & DVD system, bought in the early “noughties” - 6 grand from Peter Tyson - and the screen is still good! Not a single dead pixel (in fact I half wish the buqqer would die and I could get a bigger screen, LOL ).
Note that the Video switching was equally problematic, SCART, VGA, HDMI and so on, but the Pioneer had four assorted video inputs which we could utilise.
Anyway, the audio “base units” were Meridian, 562V preamp, 518 processor, and 565Z3 Surround Decoder, with a 421 HDMI video switcher into the Pioneer’s single HMDI input. I also needed a couple of optical to digital audio stream converters due to the limitations of the 562.
A right bl00dy rats nest of cables, and wall warts but it worked. And with four DSP5000, a DSP5000C(entre) and a DSP1500 Sub, the sound could be excellent - some of the explosions in the Star Wars movies could rattle the shelves
So, move forward twenty years, the daughters have taken their consoles, and the sources are now all HDMI (audio & video). Which means that the four main base units plus converters have morphed into a wholely digital system - 621 HDMI video switcher/audio extractor and 568mm Surround Processor. Looks a d@mn sight tidier on the rack, and it sounds better as well.
The LP12 has been “relegated” to the old 82-SNAXO-250s-SBLs system.
