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)

1 Using 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.

2 Connect the S output to a powered subwoofer.

Connecting a 5.1-Channel Ampliﬁer (RCA)

1 Using 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.

1 Using an RCA cable, connect the S output from

the GTP-870HD to the corresponding RCA input

on your powered Subwoofer.
