Connecting the Receiver —Continued
Using a suitable cable, connect the receiver’s PRE OUT:
SUBWOOFER to the input on your powered subwoofer.
If your subwoofer is unpowered and you’re using an
external amplifier, connect the PRE OUT:
SUBWOOFER to the amp’s input. If you want to use a more powerful power amplifier and
use the receiver as a preamp, connect the receiver’s PRE
OUT: L, R to the amp’s input, and connect all speakers
to the power amplifier.
