Additional Information
7Connecting the speaker system to the amplifier
Before connecting—| • Turn off the power to the amplifier before connecting the speaker |
| system; otherwise, the speakers may be damaged. |
| • The impedance of each speaker is 6 Ω. Before connecting them |
| to your amplifier, check the speaker impedance range of your |
| amplifier. If the impedance of this speaker is out of the speaker |
impedance range indicated on the amplifier, you cannot connect |
| this system to the amplifier. |
• The maximum power handling capacity of the |
| Excessive input will result in abnormal noise and possible |
7Typical connection method to an amplifier
Connect the speakers to a speaker terminal of the amplifier with the speaker cords by referring to the diagram on the left.
•Make sure to match the polarity (ª and ·) when connecting the speaker cords.Front right | Center speaker | Front left |

Warnings, Cautions and Others
| – Operating the amplifier, |
| – Tuning FM stations, |
| – |
| – Continuously reproducing high frequency oscillation or high |
| pitch electronic sounds. |
• When using a microphone, do not aim it at the speakers or use it |
| near the speakers; otherwise, the howling which occurs may |
| damage the speakers. |
| • Before replacing the cartridge, always turn off the power to the |
| turntable; otherwise, the clicking noise may damage the |
| speakers. |
7General layout of speakers
Place all speakers at the same distance from the listening position if possible.
•Usually place the center speaker close to the TV.•When you place the center speaker on a TV, make sure the surface is level and stable.
*For a subwoofer, JVC’s
Do not lean against the speakers, as the speakers could fall down or break, possibly causing an injury. Especially be careful that children do not lean against them.

7Precautions for installation
•Do not install the speakers on an uneven surface or in a place subject to vibration; otherwise, they may fall over, causing damage or injury.
–Take the occurrence of earthquakes or other physical shocks into consideration when selecting the installation place, and secure the speakers thoroughly.
•To prevent deformation or discoloration of the cabinet, do not install the speakers where they are exposed to direct sunlight or high humidity, and avoid installation near air conditioning outlets.
•Speaker vibrations may cause howling. Place the speakers as far away from the player as possible.
•The speakers are magnetically shielded to avoid colordistortions on TVs. However, if not installed properly, it may cause color distortions. So, pay attention to the following when installing the speakers.
–When placing the speakers near a TV set, turn off the TV’s main power switch or unplug it before installing the speakers. Then wait at least 30 minutes before turning on the TV’s main power switch again.
Some TVs may still be affected even though you have followed the above. If this happens, move the speakers further away from the TV.
| • Tuner reception may become noisy or hissing if a speaker is |
| installed near the tuner. In this case, leave more distance |
between the tuner and the speakers or use an outdoor antenna |
for better tuner reception without interference from the speakers. |
If the speakers are facing a solid wall or glass door, etc., it is recommended to furnish the wall with materials that absorb sounds, for example by hanging up thick curtains, to prevent reflections and standing waves.
•To use the speakers without any trouble–Do not reproduce sounds at so high a volume that they are distorted; otherwise, the speakers may be damaged by internal heat buildup.
–When moving the speakers, do not pull the speaker cords; otherwise, the speakers may fall over, causing damage or
injury.– When holding a satellite speaker, do not grasp the speaker (upper) portion, but always grasp the leg (lower) portion of the satellite speaker.

Speaker and Speaker cords—to improve the sound quality
About DD (Direct Drive) speakerDD (Direct Drive) technology improves sound localization and transmits the powerful sounds.
About the OFC cordThe core wires of the supplied speaker cords are made of OFC (Oxygen Free Copper).This OFC cord enables high quality sound reproduction.
When connecting the speaker cordsMake sure to match the polarity (ª and ·); otherwise, the surround effect will become less effective. After connecting, check that the exposed cores are fully inserted into the terminal.
When using other speaker cordsObserve the following;•Buy thick speaker cords rather than thin cords, and make them as short as possible for connection.
•Use speaker cords of the same length for both left and right speakers.•Do not use long speaker cords; otherwise, the sound quality may deteriorate.© 2004 Victor Company of Japan, Limited | 0304NSMMDWHCE |
