Been RTFMs again.

The B50 expects to see an 8 ohm speaker load and the M760 expects to see
100mw at 600 ohms on the 'music' input. Any 'sparkies' with an opinion on
how to match up these devices?

I'm not a sparkie, but if you have an 8 ohm speaker it will have
about 0.5 volts of audio across it when sounding. At this low impedance
that will be enough for the radio. It wouldn't work if you fed a high
impedance output into a low impedance input, but its fine this way
round.

My calculation suggests for full output from the music input
you'd need getting on for 8 volts of AC but I expect that'd be enough
volume for a disco.
