Hello .
The patience and the perseverance pays with Meridian.
To make the works I bought another 861v4 out of order and bought by other one components.
The 861v4 is perfect .
For your reference :
with card : OA13 + OA03 + OA03 , I drives all my speakers : 7.2
OA13 = L+R+C
OA03 = SL + SR + Sub 1
OA03 = RL + RL + Sub 2
The Meridian 800v3 .
Software : 800v3 package version="1.3"
It sings finally :
96k 24-bit MLP 5.1 : Disc DVD-A - Bleu man group - Audio
Change : Power - Display - Card 800-C00 and upgrade Software + region
I noticed at with me anomalies in the advice Meridian M-config for Cards :
M-Config 800v3
CO00 @ 1-2 : OK
OE22 @ 3-4 : Problem of crackling , The good place found : 5-6
DV20 @ 13-14 : OK
DV02 @ 15-16 : OK
DV12 @ 17-18 : OK
VE00 @ 19-20 : Change for 21-22 . Information found by the reading of photos and to manage better the heat
TM10 @ 26 : change for 24
Thank you again for your help.
