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).
