Never allow your amplifier to be driven into “clipping”. Otherwise the speakers may be damaged. . When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken never to exceed the speakers’ maximum input. . Do not attempt to clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. . Do not attempt to modify or fix the speakers. Contact qualified YAMAHA service personnel when any service is needed. The cabinet should never be opened for any reasons. . Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of speakers. PLACING THE SPEAKERS Place the speakers on a sturdy, vibration-free surface, on a well-built stand. Using as 2ch stereo speakers Better stereo images will be obtained when the speakers are slightly angled in towards the listeners. Using as main speakers in a multi channel system Position the speakers on both sides of the TV. The positioning of speakers is important, because it controls the whole sound quality of a multi channel system. Set up the speakers on the basis of your listening position by following the owner’s manual supplied with your amplifier. Note These speakers feature a magnetically shielded design, but there is still a chance that placing them too close to a TV set might impair picture color. Should this happen, move the speakers away from the TV set. Effect L Effect R Subwoofer Center NS-4HX (Main L) NS-4HX (Main R) CONNECTIONS TO YOUR AMPLIFIER CONNECTIONS TO YOUR AMPLIFIER This speaker system is capable of standard connections and bi-wired connections. Before making connections, make sure that the amplifier is switched off. SPEAKERS A B LR ++ – – + – Amplifier or Receiver Tighten NS-4HX (L) Loosen Short bar Leave the short bars in place when connecting. NS-4HX (R) Speakers output terminals of the amplifier (or receiver) CONNECTIONS • Connect the screw-type input terminals at the rear of the speakers to the speaker output terminals of the amplifier (or receiver) with the speaker cable. • Connect the (+) terminals on the amplifier (or receiver) and the speakers using one side of the cable. Connect the (–) terminals on both components using the other side of the cable. • Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, –). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass. How to connect: 1 Loosen the knob. 2 Insert the bare wire. [Remove the insulation coating at the extremity of each speaker cable by twisting the coating off.] 3 Tighten the knob and secure the cable. Test the firmness of the connection by pulling lightly on the cable at the terminal. Note Do not let the bare speaker wires touch each other as this could damage the speaker or the amplifier, or both of them.

Bi-Wired Connections This speaker system is capable of bi-wired connections. To connect the speaker to the output terminals of the amplifier (or receiver), two pairs of cables for each of woofer and tweeter are used instead of standard connections. This type of connection decreases the modulation distortion caused by electric resistance of the cables and driving current of the speakers. Consequently, purer sound quality can be expected. To utilize bi-wired connections, remove the short bars from the terminals first, and then connect the woofer and tweeter to the amplifier separately using two pairs of cables. Remove the short bars before connecting.

To remove the cover, hold on to both sides and slowly pull straight away from the speaker. To reattach, line up the four pegs on the speaker with the four corresponding holes on the inside surface of the cover and push gently. When the cover is removed, take care not to touch the speaker units with your hands or to exert excessive Note force with tools.
