External Amplifier Connections

The GFR-700’s built-in 5 x 125 watts per channel am- plifier has more than enough power for most home applications. Nevertheless, 7.1 preamp outputs are provided so you can hook the GFR-700 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-700’s built-in amplifier 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-700 to the corre- sponding RCA inputs on your external amplifier.

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-700 to the corresponding 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-700 to the corresponding input on your powered Subwoofer.
