Connecting and Setting the Input
Selection Switch
This section describes how to connect the loudspeaker to a power
amplifier or other speakers. The connector of this loudspeaker consists
of four terminals; terminal 1 of the loop through terminal is "+", terminal
2 is "+", terminal 3 is "-", and terminal 4 of the loop through terminal is
"-". Terminals 1 and 2 and terminals 3 and 4 are connected inside the
loudspeaker, respectively.
Parallel connection
Even if one speaker has a problem, other speakers will work fine.
As shown below, connect the cable to the next speaker using the same
terminal used for the cable from the previous speaker.

Loop through connection
With this connection method, it is easier to identify which speaker
is experiencing trouble. If the Euroblock connector is disconnected
from a speaker, subsequent speakers will no longer operate. Connect
the cable from the previous speaker to the IN "+" (terminal 2) and "-"
(terminal 3), and connect the cable to the next speaker to the loop
through "+" (terminal 1) and "-" (terminal 4).
