Outputs on a Jensen XA 92 amplifier

Hiya,

I picked up a Jensen XA 92 amplifier at a boot sale but it didn't come
with a manual.

It has a socket for high input and speaker outputs but I have no idea
which pins are for which.

I've had a look on the internet but I haven't been able to find any info.

Does anybody which pins are for which?


Thanks,
Matt
