I bought a second hand power amp and mixer amp on e-bay. The intention
was to use the 100volt line to run a number of speakers around my arena,
where I ride my horses, to practice my dressage to music. I know next to
nothing about 100v systems and I have now found that the company who
made the amps has ceased trading! Does anyone know ANYTHING about
"Modular Communications Ltd" of Telford Road, Bicester, Oxon, UK, or
their products. I don't know how to connect up the amps, either to each
other or to speakers. There is a number of 5-pin DIN plugs on the back
of the main amp, but not on the mixer amp

Speaker connection is simple, but you must use speaker units designed for
100 volt line as they incorporate a transformer. They are simply wired in
parallel. You can buy the transformers separately to allow the use of
'normal' speakers, though.

I'm not sure what all the 5 pin DINs would be for on the amp - but I
sincerely hope they're not used as 100 volt line connectors.
