Apparently I must have missed some information regarding the inability of the above set up working. After re-reading all of the post related to by system build and all the other posts that I could find. Is there a firm consensus that this setup will not work?
1. 568.2 set 24/96 Large Front : DSP rear (18bit 5k speaker) = No sound output from rears.
2. 568.2 set 24/96 Large Front : 24/96 rear (18bit 5k speaker) = No sound output from rears.
3. 568.2 set 24/96 Large Front : 24/96 rear (24bit 5k speaker) = Sound from rears.
Unless otherwise advised it looks like I will have to use 24 bit speakers in the rear also.
Almost there!

HS=N will limit to 41/44/18bit output all around.
If you have more modern fronts, they will up sample in their own right so you wont lose much unless input was 96/24, the generation of DSP5000/33 etc. wont upsample though.
Not a perfect solution, but will restore rear audio on 18bit rears.

I used to run a mix of 24 & 18 bit DSPs with a G91. There was a general consensus that such a mix would result in no sound, but that wasn't my experience. Technically I'm stuck in 1st gear so I can't now remember what my setting were but it is certainly possible to mix them & still get sound.

HS=N will just not upsample, you need to tell the 568 you have 18bit DSPs.
As I said earlier in the thread, as soon as you put any 18 bit DSPs in the system you are limited to 18bit.
Have you used the config programme to configure?

I don't think that is correct each speaker should be set correctly (18bit or 24bit) in the configuration ... and then set HS=N for the all multi-channel pre-sets.
This give the best compromise ... as when using say the Direct preset, which only uses the front left / right these can be feed be fed with 96K.

Carl

I get that, what I meant was, simply setting HS=N will not get your 18 bit speakers working if the 568 is set up for 24 bit speakers.
He needs to make sure the 568 is set to 18 bit output as well.
Actually is this correct?
I know this is what I was told but don't think I ever tried it out myself.

Interesting, I was told you had to limit the output to 18 bit, but never tried it myself as I always had 24bit rears, I had 18 bit 5000s but by the time I went to set them up I moved the 33s to the rear. Why are there two threads running asking the same question? Makes it all very confusing for someone like me, who gets confused easily.

18 bits is a misnomer. SPDIF is up to 24 bit irrespective of whether speakers are 18bit or 96/24. With 18bit speakers, its the sample rate that is the limiting factor - 44/48 vs 44/48/88/96 - they will all accept 24 bit but probably ignore some bits.

IIRC a 518 upped the ante to 22 bit and came close to 96/24 performance on DSP5000 18 bitters.
