b. Locate the 6.5 ft (5 m) cable with lime green 3.5 mm (RCA) stereo plugs on each end.
c. Connect the lime green plugs to the input labeled MAIN on the back of the Subwoofer. Connect the lime green plug on the other end of this cable to the lime green jack on one end of the AAC1 Y- adapter cable.
HOW TO ENHANCE PRESENTATIONS WITH DIALOGUE
The 621 output jack (step 5, CONNECTIONS) is connected to a computer sound card. A CD player or other audio source can be plugged into the unused input (AUX INPUT). Mixing of the computer audio output with another audio source can be accomplished by using the Volume Control or On/Off switch on the second audio source. A typical example may be as follows:
A lecturer may want to interject dialogue into a multimedia presentation. If the lecturer has a wireless FM microphone system the output of the microphone receiver can be connected to the unused input on the 621. When the lecturer wishes to make a comment, he either turns on the microphone switch to speak or he can raise or lower the microphone volume control to mix his voice with the computer audio program. Any
other audio device can operate in the same manner.
NOTE: Microphone location in relation tho the speakers is important. Position the microphone so that the speakers are located between the microphone and the audience, or so that the microphone is behind the speakers. If the microphone is placed in front of the speakers, feedback will result.
OTHER USES FOR THE AUX (AUXILIARY) INPUT
You may elect to hook up your Stereo system or Stereo TV to the Auxiliary input so that your speakers may be used for these devices when your primary audio device is not in use. You can also connect your modem

The satellite speakers are magnetically shielded to prevent color distortion on video displays. However, the subwoofer is not magnetically shielded and should not be placed in close proximity to a computer monitor, television or computer hard drive.

IMPORTANT
If you experience any difficulties with your speaker system, check the Troubleshooting section of this Guide. The answers to most setup and performance questions can be found there. If you cannot find the information you need, please call our customer service team for assistance before returning the speakers to your retailer under their return policy. We're available 7 days a week for your convenience:
Monday to Friday: 8:00 a.m. to 12:00 midnight
Saturday & Sunday: 9:00 a.m. to 5:00 p.m.
CONNECTIONS:
COLOR CODING: Notice that the input jacks on the subwoofer are color coded to prevent errors. The plugs that are inserted into these jacks have matching colors. As an example, the left front speaker satellite has a brown connecting plug. The plug is inserted into the left front jack with the brown color strip marking. All other connections are made in the same way.
Do not insert the power plug into an AC outlet until all connections are made.
To insure
1.Connect the orange plug from the 621 Right Satellite to the jack marked RIGHT at the rear of the Subwoofer.
2.Connect the brown plug from the 621 Left Satellite to the jack marked LEFT at the rear of the Subwoofer.
3.Connect the gray DIN plug from the System Controller unit into the DIN jack on the Subwoofer. Note that the DIN plug has an arrow. The arrow should be faced to the right for correct insertion into the DIN jack on the subwoofer. Please insert this plug securely.
4.Turn off the audio source device (console gaming system, portable music system, etc.). Shut computer systems down using the manufacturer’s recommended procedures.
5.Locate the 6.5 ft (5 m) cable with lime green 3.5 mm (RCA) stereo plugs on each end. Connect one lime green audio plug to the MAIN INPUT

The Power On/Off button is located on the System Controller unit. Press the POWER button to turn on the speaker system. Push it again to turn the unit off. A green LED power indicator on the base of the controller will glow to show power is on.
VOLUME CONTROL
A Volume Up button and a Volume Down button are located on the System Controller unit. Repeated pressing of the buttons changes the volume setting by increments.
SUBWOOFER VOLUME CONTROL (BASS LEVEL)
With the Subwoofer in the desired location, the volume control is used to mix the level of the Subwoofer with the Satellite speakers. Mixing is usually done by playing a wide variety of music and speech and adjusting the control until a natural sound is obtained. See PLACEMENT OF SPEAKERS below.
MAIN INPUT AND THE AUX (AUXILIARY) INPUT
Both inputs are equal. The Aux Input is also located at the rear of the Subwoofer. One input can be used for the computer output and the other as described in How To Enhance Presentations With Dialogue below. Make connections as described in step 6 (CONNECTIONS) above. Do not insert the AC power plug into the wall outlet before all connections are made.
PLACEMENT OF SPEAKERS
All stereo information is heard from the satellite speakers. The Subwoofer contains no stereo information and sound is
WARNING: The Subwoofer is not magnetically shielded. The Subwoofer should NOT be placed near video display devices such as a TV or computer monitor. The subwoofer should NOT be placed near computer hard drives. Position the subwoofer at least 2’ (.6 m) away from computer hard drives, or any other media that uses magnetic encoding.
The Satellite speakers are magnetically shielded and can be placed close to a video display (TV, computer monitor) without distorting the video image. Best stereo effect is obtained by placing the speakers as far apart as their wiring allows.
TROUBLESHOOTING TIPS
Find more troubleshooting tips in the FAQs located in the Customer Support area of our web site: www.alteclansing.com.
Q. When connected to my computer sound card, should I use the Windows volume control to adjust the volume of my speakers?
A. No. Adjust the Windows controls to about center as a starting point and then use the speaker controller to adjust volume control. If the volume is turned too high on the sound card, it can distort the sound.
Q. One and sometimes both of my speakers do not work.
A. Check the input cable from speaker to the audio source and make sure that it is connected to the
Q. My speakers give off a crackling sound (or static, or other noise). What could be wrong?
A. Check all cables and make sure that they are connected to
Q. What can cause radio feedback?
A. If you are living near a radio tower you could have interference caused by radio frequency. Try moving your speakers to see if the interference goes away; if not, you may be able to purchase a stereo cable from your local retailer that has a higher percentage of shielding.
Q. Can I hook my speakers to my TV or Stereo?
A. Yes, as long as your TV or Stereo has an unamplified source which is
Q. I have very little bass coming from my Subwoofer. How do I increase the bass output?
A. Adjust the BASS control through your audio sound source (computer sound card control, CD player control, etc.). Check to make sure that all of your cables are hooked up correctly and are making a good connection.
Q. I have a low hum coming from my Subwoofer. Is this normal?
A. Yes. The AC in your house is at 60 cycles per second, which is within the audio frequency of your subwoofer. Some low hum is natural and can be detected when your speaker system is powered on without source audio playing, or when volume is set at an extremely low level.
Q. I have a loud hum coming from my Subwoofer. What should I do?
A. Move the power cord from the power surge protector (if applicable) and plug directly into an AC wall outlet. Move your cables and check to see that they are making a good connection. If you disconnect your stereo cable from the audio source and the loud hum goes away, then you may need to adjust the volume control in your audio source as you may be overdriving the volume settings on your speaker system. If you are using your 621 speakers with your computer system, just click on the speaker icon located next to the digital clock to the lower right of your Windows 9X or 2000 screen and adjust the volume.
Q. When I put my Subwoofer on my desk my monitor distorts. Why?
A. The Subwoofer is not magnetically shielded, and this can cause distortion if it is less than 3 feet from your monitor.
Q. The DIN connector from the controller has multiple pins on one end,
