Usage Features

The manual emphasizes proper setup and connection for optimal performance and to prevent damage.

Speaker Placement:

Speakers should be placed on flat, secure bases.
Avoid placing speakers too close to floors, walls, and corners, as this can result in excessive bass.
Walls and windows should be covered with thick curtains for better sound.
Maintain at least 10 mm (13/32") clearance from the system for proper ventilation.
For surround speakers (SB-HS650P-S), they should be placed at approximately the same distance from the seating position as the front and center speakers.
Left and right surround speakers are interchangeable, and there is no specific left or right channel orientation required.
The recommended angle for surround speakers relative to the listening position is 120°.

Speaker Cable Connection:

Speaker cables must be connected before the AC power supply cord.
The load impedance of any speaker used with this unit must be 3 Ω.
Ensure correct polarity: positive (white) wires to positive (+) terminals and negative (blue) wires to negative (-) terminals.
Twist and pull off the vinyl tip of the speaker cords. If no vinyl tips, connect bare ends directly to terminals, ensuring wires are not unraveled.
Insert the wire into the rear panel of the unit and close the lever.
Caution: Do not short-circuit or reverse the polarity of speaker wires, as this can damage the speakers. Speaker cable stickers are included to facilitate correct connection.

General Speaker Use Notes:

Only supplied speakers should be used; using other speakers can damage the unit and negatively affect sound quality.
Avoid playing sound at high levels for extended periods to prevent damage and shorten speaker life.
Reduce volume when:
- Playing distorted sound.
- Speakers are reverberating due to a record player, FM broadcast noise, or continuous signals from an oscillator, test disc, or electronic instrument.
- Adjusting sound quality.
- Turning the unit on or off.
Irregular Coloring on Television: Front and center speakers can affect television picture quality. If irregular coloring occurs, turn the television off for about 30 minutes to allow the demagnetizing function to correct the problem. If it persists, move the speakers further away from the television.
Safety Warning: The main unit and supplied speakers are to be used only as indicated in this setup. Failure to do so may lead to damage to the amplifier and/or speakers, and may result in fire. Consult a qualified service person if damage occurs or if performance changes. Do not attempt to attach these speakers to walls using methods other than those described in this manual.
Handling: Do not touch the front netted area of the speakers; hold them by the sides.
