Alesis 5.1 manual Connecting the speakers, Connecting the Digital SoundTouch Control Center

Position the Digital SoundTouch™ Control Center where it is easy to reach.

Connecting the speakers:

Once you have positioned the speakers, connect them to the subwoofer. Two 6’ lengths and three 15’ lengths of speaker cable are included. If you want to position your speakers further

away, you can use commercially available speaker cable.

Important: Do not plug the subwoofer into AC power until all connections have been made. Improperly connected or shorted speaker wires will damage the system.

On the back of each speaker, unscrew the terminal connectors until you see the holes through the center posts. Insert the cable into the holes, and tighten the connectors.

Connect the speaker end of each wire before connecting the subwoofer end.

On the back of the subwoofer, press the lever on the terminal and insert the cable. Release the lever and the cable will be locked into position. To avoid wiring confusion, connect the speakers to the subwoofer one at a time. Be sure to connect the cables from the red and black terminals on the speakers to the corresponding red and black terminals on the subwoofer. The cable has a white stripe to aid in maintaining proper polarity.

Important: To avoid shorting out the sys- tem, make sure that no exposed wires

touch each other and that no stray wires touch other terminals.

When properly connected, the speakers will operate “in phase” and your sound quality will be optimized. If not connected properly, the system will operate “out of phase.” While this won’t damage the system, the sound will be less clear and the bass sounds will be diminished.

Important: Only use the ProActive 5.1 satellites with the ProActive 5.1subwoofer. The system is not designed to be used with any other speakers.

Connecting the Digital SoundTouch™ Control Center:

Attach the D-sub cable from the Digital SoundTouch™ Control Center to the subwoofer and tighten the thumbscrews on each side of the connector. To extend the cable to the control center, use only a Alesis approved extension cable. Contact Alesis for more information and availability.

Important: Do not use an extension cable designed for computer monitors. Computer monitor cables may damage your ProActive 5.1 system.

Connecting your Audio Sources:

The ProActive 5.1 speaker system can connect to as many as 4 different audio sources simultaneously. These sources can be connected in a variety of different configurations, depending on the type of equipment you have.

NOTE: To use the optical or coax jacks, you will need to purchase an optical or coax cable separately. These are readily available at most consumer electronics retailers.

Instructions are provided below for each type of equipment.

A common configuration might be:

•PC Audio Sound card to 6-channel direct using multiple RCA phono connectors

•Mixer console using 1/4” TR jack outouts

•Multi-channel Recorder with AES/EBU output (optical or coax)

•Analog audio into standard mini-jack

NOTE: These represent only some of the possible configurations

Digital Connection

If your sound card has a digital output jack, you can use it to connect to the Digital SoundTouch™ Control Center. The control center supports either an optical or a coaxial connection. Check your source device documentation for instructions on how to enable it’s digital output.

Analog Connection

Use the 6-channel direct input cables to connect the Digital SoundTouch™ Control Center to the analog jacks on your sound card, mixer, recorder, etc. There are 3 types of analog inputs to the system: mono 1/4” TR jack, mono RCA phono and 3.5mm 2-channel mini-jack. For optimal sound, connect only those cables necessary for your sound card and leave the other cables unattached at both ends:
