Speakon speaker outlets carrying output via the monitor route , via
monitor1&2 faders and mon1/mon2 rotary controls on each channel. But
main
sliders per channel and 2 master sliders only control to phones output.
I'm
loathe to burrow into the mixer (all those damn fittings) if its a RTFM
thing or a missing jumper lead , secret switch combination or something
silly. It was lent to someone and came back like this and no
knowledge/divulging of course




I'm having a little difficulty translating that, but many of these type of
units, including this one, are switchable so that it behaves either
normally
as a Stereo amplifier, or can be switched to one power amp being fed a
Mono
mix from the main Stereo Bus, and the other power amp running a Monitor
Send, so the act can have a Monitor on stage as well as a (Mono) PA
system.


There should be a switch somewhere that does this, probably marked
Main/Monitor or something.

Its annoying the easily overlooked significance of the "o" and "."
distingushing mono (monophonic) from mon. (monitor), why not fold. instead
of mon. .

Looks as though its diverter switch problems on axial type 1/4 inch pcb
mount sockets. Oddly both failing at the same time , perhaps someone tripped
over leads, but even then ,both failing together seems odd.
Physically jumpering master L line-out to PA-in L, and same for the right
brought normal operation. Since plugging in jacks, Left diverter is now
working as default structure of master to PA and the other one still
erroneous.
So looks as though I can leave the mixer intact and just replace the back
board patching sockets.
