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.
