do not work anymore. Connect the previous speaker wires to "+" (terminal 2) and "-"
(terminal 3) of IN and the next speaker wires to "+" (terminal 1) and "-" (terminal 4)
of the loop-through connection.

consideration the weight of the loudspeaker and the state of the installation. If the
wire is too long, the loudspeaker may hit someone if it falls.
