2 Connection of the Speaker Cables
· Be sure to connect speaker cables before connecting the
AC power supply cord.
· The load impedance of any speaker used with this unit must
be 6 .
· Be sure to connect the cable from the right speaker to the
right terminal and the cable from the left speake r to the left terminal.
1. Twist and pull off the vinyl tip of the speaker cords. If the speaker cords do not have vinyl tips, connect them directly to the terminals. Make sure the bare ends of the wires are not unravelled.
2. Insert the wire to the rear panel of the unit and close the lever.
Notes :
· To prevent damage to circuitry, never short-circuit positive (+) and negative (-) speaker wires.
· Be sure to connect only positive (red) wires to positive (+) terminals and negative (black) wires to negative (-) terminals.
Placement
Speakers are designed identically so that no left or right channel orientation is necessary.
Use only the supplied speakers
The combination of the main unit and speakers provide the best sound. Using other speakers can damage the unit and sound quality will be negatively affecte d.
Note
· Keep your speakers at least 10 mm away from the system
for proper ventilation.
