3 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 Ω.
· Be sure to connect the cable from the right speaker to the right terminal and the cable from the left speaker 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 (white) wires to positive (+) terminals and negative (blue) wires to negative (-) terminals.

· Reduce the volume in the following cases to avoid damage.
− − −
− When playing distorted sound.
− − −
− When the speakers are reverberating due to a record player, noise from FM broadcasts, or continuous signals from an
oscillator, test disc, or electronic instrument.

If irregular coloring occurs on your television
The front and center speakers are designed to be used close to a television, but the picture may be affected with some
televisions and setup combinations.
If this occurs, turn the television off for about 30 minutes.
The demagnetizing function of the television should correct the problem.
If it persists, move the speakers further away from the television.
Caution
Do not touch the front netted area of the speakers. Hold by the sides.
e.g. Center speaker
Do not stand on the base. Be cautious when children are near..
e.g. Front speaker
