Subwoofer Volume The SUBWOOFER knob on the control pod controls the volume of the subwoofer. Turn the knob clockwise to increase the subwoofer volume and counterclockwise to decrease the subwoofer volume. Headphones To use headphones with the system, plug them into the labeled jack on the control pod. When headphones are connected, the speaker system is muted. System Specifications* Altec Lansing’s superior sound comes from our patented Dynamic EQ technology, which utilizes custom-built, high-fidelity drivers, state-of-the-art equalization circuitry, and a harmonious mix of the following specifications: Sound Pressure Level (SPL): 103 dB System Response: 40 Hz – 20 kHz (-10 dB) Total Continuous Power: 50 Watts RMS Signal to Noise Ratio • Front Speakers: 5 Watts/channel @ 8 ohms @ 1 kHz input: > 80 dB @ 10% THD @ 150 Hz – 20 kHz Drivers (per satellite): One 2" full-range driver 2 Channels Loaded Subwoofer: One 5.25" woofer • Rear Speakers: 5 Watts/channel @ 8 ohms @ 10% THD @ 150 Hz – 20 kHz 2 Channels Loaded POWER REQUIREMENTS • Center Speaker: 10 Watts @ 8 ohms @ 10% THD @ 150 Hz – 20 kHz USA, Canada and applicable Latin American countries: 120 V AC @ 60 Hz Single Channel Loaded Europe, United Kingdom, • Subwoofer: 20 Watts @ 8 ohms @ 10% THD @ 40 – 150 Hz applicable Asian countries, Argentina, Chile and Uruguay: 230 V AC @ 50 Hz Single Channel Loaded ETL/cETL/CE/NOM Approved *Power rating conforms to FTC Amplifier Rule #16 C.F.R. Part 432. No LEDs are lit. Power isn’t turned on. AC power cord isn’t connected to the wall outlet. Surge protector (if used) isn’t powered on. Wall outlet not functioning. Turn on the speaker system by pushing the On/Off button located on the control pod. An LED will light on the control pod when the power is ON. Check to see if the “Power On” LED is illuminated on the control pod. If not, connect AC power. If the 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 verify the wall outlet is working. Troubleshooting Symptom Possible Problem Solution 3 No sound from one or more speakers. No sound from center or rear satellites. Crackling sound from speakers. Sound is distorted. Radio interference. No sound from subwoofer. Low hum from subwoofer. Loud hum from subwoofer. Too much bass from subwoofer. Distorted monitor. Power isn’t turned on. Volume is set too low. Speaker system isn’t connected to audio source. Speaker system is connected to wrong output on audio source. Problem with audio source device. Switch on the rear of the subwoofer is not in the proper position. Rear or center level is set too low. Bad connection. Volume level in computer operating system is set too high. A problem with your audio source device. Volume level set too high. Computer operating system volume level is set too high. Sound source is distorted. Too close to a radio tower. Subwoofer volume is too low. Bad connection. The AC in your house is at 60 cycles per second, which is within the audio frequency of the subwoofer. Bad connection. Volume on your audio source device is set too high. Subwoofer volume is too high. Subwoofer too close to monitor. Verify the AC power cord is plugged into the wall outlet. Turn on the speaker system by pushing the On/Off button located on the control pod. An LED will light on the control pod when the power is ON. 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. Check plug connections on the audio source. Make sure the signal cable(s) is/are inserted firmly into the correct jacks. Make sure the lime green 3.5mm stereo cable is connected and fully inserted into the “line-out,” “audio-out,” or the headphone jack of the audio source. Test the speakers on another audio device. Remove the lime green 3.5mm stereo cable from the audio source device and connect it to the “line-out,” “audio-out,” or the headphone jack of another audio source. Change the position of the switch. Increase the rear or center speaker volume level. Check all cables. Make sure they are connected to the “line-out” or “audio-out” jack on your sound card or other audio source — NOT “speaker-out.” Check the computer operating system volume level and decrease it if necessary. Unplug the stereo cable from the audio source. Then plug it into the headphone jack of an alternate audio source (e.g., Walkman, Discman or FM radio). Turn the VOLUME knob counterclockwise to lower the volume. Adjust the computer operating system volume and balance levels to the center as a starting point, then adjust the level on the speaker using the volume control. WAV files are often of poor quality. So distortion and noise are easily noticed with high-powered speakers. Try a different sound source such as a music CD. Move your speakers until the interference goes away. Increase the subwoofer volume on the control pod. Check to make...
