I have recently received a cheap Chinese Sub which was badly dinged up in
the delivery (thanks a bunch, DHL...) and another one is being sent for just
a tenner to cover the shipping charges. So I've taped this one up pro temps
and have had some noises out of it and will give it a good thrashing
shortly.

Anyway , the instructions are in German, so I've got some questions about
the connections, which look quite comprehensive - see:

I take it the 'Hi Level In' and 'Hi Level Out' is where the speaker output
wires from a stereo amp are routed for a normal 'sub/sat' stereo setup?
(amp - sub - speakers.)

Yes. I envisage the subwoofer would rely on the main amplifier power to
move the air, using only active circuitry to provide crossover and phase
adjustment.

What about the 'Line In' and 'Line Out' (which I have never seen before) - I
presume the single SW phono connection from the AV amp can go to either of
the Line In sockets and they are 'commoned', but what are the 'Line Out'
phono sockets for? What would you do with them? (OK, probably nothing for
normal use, but I'm curious....??) Finally the Phase Switch - I haven't
heard much difference with either setting yet. Is there a 'correct' setting?

The one that sounds the best.

The phono passthrough would be for you to insert the subwoofer between a
preamplifier and a power amplifier for the front speakers.
