Power amplifier
Connecting power amplifiers and two surround back speakers
Connecting power amplifiers
Using auxiliary power amplifiers allows you to listen at louder
volumes than with the TX-DS787 alone. If power amplifiers are
used, connect each speaker to the corresponding power amplifier.
Connecting two surround back speakers
To connect two surround back speakers, connect a power amplifier
to the PRE OUT SURR BACK terminals on the TX-DS787, and
connect the surround back speakers to that power amplifier. You
will also need to make the appropriate setting in the OSD Menu:
Speaker Setup → Speaker Config → Surr Back Out (see page 30).
