Powered Subwoofer Features

If you are using equipment that has only one monaural subwoofer-output jack, you may make the connection between this jack and the left or right low-level input of the powered subwoofer. If more volume is desired even after increasing the subwoofer’s separate level control, use a “Y” audio connector to connect both the left and right low- level subwoofer inputs to the single monaural subwoofer output jack.

Dual Subwoofers with Low-Level Connection:

When using two powered subwoofers, or will be connected to the right channel and the other to the left channel. This requires using RCA audio cables to connect the left output of your preamp or decoder to the left low-level input on the subwoofer that you are designating as the left-channel sub.

Repeat this process for either subwoofer, using the right-channel low-level outputs and right-channel low-level inputs of the subwoofer.

Single Subwoofer with High-Level Connection:

You will be connecting your subwoofer directly to your ampliﬁer’s main speaker outputs with this method and then conne3cting your speakers to the subwoofer’s outputs.

To do so, connect the left-channel main speaker output of your ampliﬁer to the high-level left-channel input terminals of the subwoofer. Then connect the left main speaker to the left-channel output on the subwoofer. Repeat this process for the right channel. We suggest using good-quality, heavy-gauge cables for the ampliﬁer-to-subwoofer-to- speaker connections.

Dual Subwoofers with High-Level Connection:

Connect the left-channel speaker terminals of your ampliﬁer to the high-level, left-channel input terminals of the subwoofer that you are using for the left channel. Repeat the process for the right-channel subwoofer, using the right-channel outputs and inputs.

Now connect your main left and right speakers directly to your subwoofer speaker outputs. Your center and rear speakers are connected to your ampliﬁer as normal.

Alternate Subwoofer High-Level Connection:

With some system conﬁgurations it may not be convenient to connect the main loudspeakers through the subwoofer high-level outputs. Under these conditions, an alternate connection method may be used. To accomplish this, connect the left-channel speaker level input of your subwoofer to the left-channel speaker output of your ampliﬁer. Repeat the process for the right-channel connections of your subwoofer and the main right-channel speaker. This means that you are connecting the subwoofer high-level inputs in parallel with the connections for your main speakers. (See diagram alternate connection 2.)

Subwoofer Connections with High-Pass Filters: Phase Technology powered subwoofers are equipped with internal high-pass crossovers providing a -6 dB per octave slope for the high-level outputs.

Some premium models also feature an active crossover with -24 dB per octave slope for its low-level output. (Refer to the speciﬁcations for your model.)

When using these low-level outputs, it is necessary to have either separate preamp inputs and outputs or separate component ampliﬁers, preampliﬁers or decoders. The low-level inputs should be connected as noted in this manual. The low-level outputs from the subwoofer must be connected back to a preampliﬁer, a decoder, or main ampliﬁer inputs with standard RCA-type connecting cables. Be certain to connect the respective left- and right-channel inputs

and outputs as noted.
