Clearly, connecting speaker outputs to line level inputs is not a good

thought that I could connect some kind of inductor to step down the

You need an attenuator 'pad' made from a couple of resistors. 33k and 1k would
probably work fine. Connect the 2 resistors in series with the speaker output
connected to the 'far end' of the 33k. Connect the junction of the 2 resistors
to the line input and the remaining connection to the 1k to ground (use the
screen/shield of the line input).


Thanks very much!

If you don't mind, I'm going to reiterate so I'm sure I've understood,
using an RCA connector for the line input.

Connect the positive speaker output (red) to a 33K resistor. Connect
the other end of the 33K resistor to the "centre" of the RCA
connector, and also to a 1K resistor. Connect the outer part of the 1K
resistor to the "outside" of the RCA connector.

Correct.


This leaves the negative speaker output (black) not connected to
anything. Is this OK?

It is.
