Ampliﬁer/Subwoofer Connections (RCA)

Follow these steps to connect the GTP-870HD to a power ampliﬁer using the 7.1 preamp (unbalanced) outputs. You can also follow these steps to connect a powered subwoofer.

Connecting a 7.1-Channel Ampliﬁer (RCA)

1Using seven RCA cables, connect the 7.1 channel preamp outputs (RF, RS, RB, C, LF, LS, and LB) from the GTP-870HD to the corresponding RCA inputs on your ampliﬁer.

2Connect the S output to a powered subwoofer.

Connecting a 5.1-Channel Ampliﬁer (RCA)

1Using ﬁve RCA cables, connect the 7.1 channel preamp outputs (RF, RS, C, LF, and LS) from the GTP-870HD to the corresponding RCA inputs on your ampliﬁer.

2 Connect the S output to a powered subwoofer.

Connecting a Powered 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 GTP-870HD to the corresponding RCA input on your powered Subwoofer.
