Powered Subwoofer Connections

For proper polarity and, thus, ideal system performance, always connect the positive side of the cable to the positive terminals on your speakers and ampliﬁer and the negative side of the cable to the negative terminals.

Front Speakers: The pair of front speaker connections (left and right) on your ampliﬁer will be labeled “Front” or “Main.” Connect the speaker cables for your left and right front speakers using these terminals and then connect the cables to the speakers. Observe positive and negative polarities.

Rear Speakers: The pair of rear speaker connections (left and right) on your ampliﬁer will be labeled “Rear” or “Surround.” Connect the speaker cables for your left and right rear speakers using these terminals and then connect the cables to the speakers. Observe positive and negative polarities.

Center Speaker: The center speaker connections on your ampliﬁer will be labeled “Center” or “Center Channel.” Connect the speaker cables for your center channel speaker using these terminals and then connect the cables to the speaker. Observe positive and negative polarities.

There are two ways to connect Phase Technology Powered Subwoofers to your system: through low-level and high- level connections. These methods differ depending on whether you are using components or a multi-purpose receiver; whether your ampliﬁer, receiver, and surround-sound decoder have separate subwoofer output connections; and whether you are using one or two subwoofers in your system.

Therefore, please read the following guidelines carefully. Be sure to choose one or the other of the connection options, as using both at the same time could severely damage your speakers and ampliﬁer. And always remember to keep the polarity connections correct (positive to positive and negative to negative).

To prevent low-frequency information from being fed to your main speakers, we recommend connecting your front speakers directly to the subwoofer using the sub’s own high-level-output speaker terminals. This method of connection reduces the stress on the main speakers; it requires using the high-level connection guidelines below for your subwoofer(s).

After your powered subwoofer is properly connected, plug it in to AC power and turn the subwoofer’s own level control all the way down, counter-clockwise, before activating the subwoofer’s power switch. Then, gradually increase the volume level while playing music you are familiar with until the bass level is to your liking.

Special Note: System Adjustment for Low-Level Connections

When using a subwoofer that is connected to your ampliﬁer through the low-level inputs, it is recommended that your surround-sound processor (or multi-channel ampliﬁer) be set, if possible, to enable a low –frequency roll-off for your full-range speakers.

This adjustment, sometimes labeled “small speakers” will enable a smoother crossover transition between your primary speakers and the subwoofer.

Single Subwoofer with Low-Level Connection:

Use this method if 1) you use a separate preampliﬁer and power ampliﬁer, 2) if you use a receiver with preampliﬁer outputs and/or subwoofer output jacks, or 3) if you use a separate surround-sound decoder with your ampliﬁer.

Use a pair of audio-interconnect cables – the ones with the colored RCA plugs – to connect the left and right outputs of your pre-ampliﬁer or surround decoder to the left and right low-level inputs of your powered subwoofer. Connect your front, center-channel and rear speakers to our ampliﬁer as previously outlined in this manual.
