manual abstract
Typically, the outputs will be marked as “front output” and “rear output.” In some cases, slightly different terminology may be used. The sound card’s documentation should help you determine which outputs to use with your speaker system. 1. Connect the lime green 3.5 mm stereo plug, which is connected to the right speaker, into your sound card’s input labeled “FRONT,” which is also lime green in color. 2 System Specifications Peak Power: Frequency Response: Signal to Noise Ratio @ 1 kHz Input: 2.4 W Continuous RMS; 3.5 W Total Peak Power (Power rating conforms to FTC Amplifier Rule #16 C.F.R.

No sound from one or more speakers. Crackling sound from speakers. Sound is distorted. Radio interference. AC cord isn’t connected to the wall outlet. Surge protector (if used) isn’t powered on. Wall outlet is not functioning. Power isn’t turned on. AC power cord is not plugged in. Volume is set too low. Audio cable isn’t connected to audio source. Audio cable is connected to wrong output on audio source. Left speaker is not connected to the right speaker. Problem with audio source. Bad connection. Volume control in Windows is set too high. A problem with your audio source. Volume level is set too high. Windows volume control is set too high. Sound source is distorted. Too close to a radio tower. Check to see if the power on LED is illuminated on the right speaker. If not, connect AC power. If the speaker’s AC power cord is plugged into a surge protector, make sure the surge protector is switched on. Plug another device into the wall outlet (same jack) to confirm the outlet is working. Turn volume control knob clockwise. Verify the speaker’s AC power cord is plugged into the wall outlet and a power LED will illuminate. Turn the volume knob clockwise to raise the volume. Check volume level on the computer sound card or alternate audio source device and set at mid-level. Connect the lime green 3.5 mm stereo audio cable to the audio source. Make sure the cables are inserted firmly into the correct jacks. Make sure the lime green 3.5 mm stereo cable is connected and fully inserted in the “line-out” or “audio-out” jack on your sound card or other audio source. Ensure brown cable, connected to the left speaker is inserted into “to left speaker” output on right speaker. Test the speakers on another audio source by removing the lime green, 3.5 mm cable from the audio source and connecting it to the “line-out” or headphone jack of a different audio source (e.g., portable CD, cassette player or FM radio). Check all cables. Make sure they are connected to “line-out” or “audio-out” jack on your sound card or other audio source—and NOT “speaker-out.” Check the Windows volume control and decrease if necessary. Unplug the lime green 3.5 mm stereo cable from the audio source. Then plug it into the headphone jack of an alternate source (e.g., portable CD player, cassette, FM radio, etc.) Decrease volume level by turning volume control counter-clockwise. Check the Windows volume and decrease if necessary. .WAV and .MID files are often of poor quality; therefore distortion and noise are easily noticed with high-powered speakers. Try a different audio source such as a music CD. Move your speakers to see if the interference goes away. You may be able to purchase a shielded cable at your local electronics store.
