Anyone know of pics of the interior?

A previous "repairer" removed all fuses , ratings on overlay , so ok. But
did not mark the ribbons before removing all of them. Majority are
mateable
without ambiguity. There are 2x 16 way ribbons with exactly the same IDC
connectors that could go to either of 2 places on the central board
holding
the graphic sliders and LED bargraphs.
Completely different lengths to the ribbons , does not help to decide as
the
headers are adjascent
One ribbon is from Conn1 of rear INSert sockets
The other from the CCD display board
Cannot start rectifying whatever the underlying problem was, before
sorting
out this added problem



I have a Horizon here, which I'm pretty sure is the same layout as the
Vision - I have seen lots of this series of Powered Mixer, and they are all
very similar except different numbers of channels and Power amp modules.

On this one, the front panel PCB these both plug into is marked "R1A8-4".
The connector closest to the back of the mixer (and thus closest to the
alphanumeric display) is the one that goes to the DSP board.

This cable should be the shorter one - it thus makes logical sense that the
shorter cable travels the shortest distance between the 2 different
connection possibilities, the Insert cable having the longer route and the
longer cable.


I seriously doubt anything will blow up if the wrong one is connected to the
wrong socket, unless Studiomaster were monumentally stupid at design stage!

Considering some of the monumentally stupid design gaffes i have made, i
would be rather uncomfortable making such an assertion. To say nothing of
what i have seen done by others from my point of view.
