Instruction Manual
Thank you for purchasing an Onkyo Speaker
System.
Please read this manual thoroughly before using
it. Following the instructions in this manual will
enable you to obtain optimum performance and
listening enjoyment from your new Speaker Sys-
tem.
Please retain this manual for future reference.
Before Using Your New Speakers
• The speaker cabinets are made out of wood
and are therefore sensitive to extreme tem-
peratures and humidity. Do not use them in
locations subject to direct sunlight or in
humid places, such as near an air conditioner,
humidifier, bathroom, or kitchen.
• Place the speakers on sturdy, flat surfaces.
Putting them on uneven or unstable surfaces
where they may fall and cause damage will
affect the sound quality.
• Do not keep water or other liquids close to
the speakers. If a liquid is spilled over them,
the woofer and tweeter inside may be dam-
aged.
• Do not handle the speakers with wet or damp
hands.
In catalogs and on packaging, the letter at the end of
the product name indicates the color. Specifications
and operation are the same regardless of the color.
The speakers can handle the specified input power
when used for normal music reproduction. If they’re
fed any of the following signals, even if the input
power is within the specified rating, excessive cur-
rent may flow in the speaker coils, causing burning
or wire breakage:
1. Interstation noise from an untuned FM radio.
2. Audio from a cassette that’s being fast-forwarded.
3. High-pitched sounds generated by an oscillator,
electronic musical instrument, and so on.
4. Amplifier oscillation.
5. Special test tones from audio test CDs and so on.
6. Thumps and clicks caused by connecting or dis-
connecting audio cables (always turn off your
amplifier before connecting or disconnecting
cables).
7. Microphone feedback.
The speakers contain powerful magnets. Do not put
metal items, such as screwdrivers, close to the speak-
ers, as they may be attracted toward the magnet,
causing injury, or damage to the tweeter diaphragm.
