9.2. Connections to the Rear-Mounted Connectors
Notes
• Use the appropriate type of screwdriver for the connector wiring screws.
• When using stranded or shielded cable, do not solder the stripped and exposed ends.
When the cable is clamped, the solder becomes crushed, increasing contact resistance and possibly
resulting in an extreme rise in cable joint temperature.

Step 1. Loosen the terminal screw to insert the cable
into the connector, then retighten the screw.
Note
Tug lightly on the cable to be sure that it does
not pull free. If the cable pulls free, loosen the
terminal screw again and reconnect from the
beginning.
Step 2. Insert the connector into the rear-mounted
socket.
Step 3. Tighten the fixing screw.
Note
Take care not to reverse Steps 1 and 2.
When tightening the terminal screw, force is applied to
the connector pins on the internal circuit board,
possibly resulting in poor contact.
Refer to the following table for the distance of the cable to be connected to the Speaker Output terminal.
