External Ampliﬁer Connections

The GFR-700HD’s built-in 5 x 145 watts per channel (EIA/CEA 490-A) ampliﬁer has more than enough power for most home applications. Nevertheless, 7.1 preamp outputs are provided so you can hook the GFR-700HD up to an even bigger rig (the GFA-7707 comes to mind), if desired.

More importantly, these preamp outputs can also be used in tandem with the GFR-700HD’s built-in ampli- ﬁer to connect a subwoofer (S) and surround back (RB/LB) speakers.

Connecting an Ampliﬁer

1Using eight RCA cables, connect the 7.1 channel preamp outputs from the GFR-700HD to the cor- responding RCA inputs on your external ampli- ﬁer.

•Connect the RF, LF, RS, LS, RB, LB, and C outputs to the ampliﬁer and the S output to a powered subwoofer.

2If you have a 5.1-channel ampliﬁer, use ﬁve RCA cables and omit the RB and LB connections. Con- nect the S output to a powered subwoofer.

Connecting Surround Back Speakers

For full 7.1 surround sound, you’ll want to connect surround back speakers, which must be connected to an external ampliﬁer.

1Using two RCA cables, connect the RB and LB outputs from the GFR-700HD to the correspond- ing RCA inputs on your external ampliﬁer.

2Connect your right and left surround back speak- ers to the external ampliﬁer.

Connecting a Subwoofer

The “.1” in 5.1 and 7.1 stands for the all-important Subwoofer, also known as an L.F.E., or low-frequency effects channel. No home theater would be com- plete without a subwoofer rumbling your listening area with thunderous bass.

1Using an RCA cable, connect the S output from the GFR-700HD to the corresponding input on your powered Subwoofer.
