This amplifier allows you to switch between 3
different surround speaker configurations (A, B,
and A+B). There are two sets of surround
speaker terminals (A and B). The SPEAKERS
SURROUND A terminals are for standard
operation with up to 7.1 channels. Use the
SPEAKERS SURROUND B terminals to
connect additional surround speakers for use in
either a separate 5.1 channel system
(independent from the 7.1 channel system), or as
additional speakers to make the 7.1 channel
system into a 9.1 channel system.
Using only the speakers connected to
the SPEAKERS SURROUND A terminals
This is a standard speaker system for use with
movies and Super Audio CDs.
Using the speakers connected to the
SPEAKERS SURROUND B terminals
You can create two separate surround systems, a
7.1 channel system for movies and a 5.1 channel
system for Super Audio CDs. In this case,
connect the surround speakers for movies to the
SPEAKERS SURROUND A terminals and
connect the surround speakers for music to the
SPEAKERS SURROUND B terminals. This is
useful if you mainly listen to Super Audio CDs,
but also want to enjoy a theater-like sound stage
for movies.
Selecting the front speaker
system
Set the SPEAKERS FRONT switch according
to the front speakers you want to drive.

“8Ω”, connect speakers with a nominal impedance
of 16 ohm or higher. When the IMPEDANCE

**When you want to turn off the sound output from
SPEAKERS jacks while turning on the sound
output from PREOUT jacks, set the SPEAKERS
FRONT switch to “A”, “B” or “A+B”, then set
“OUTPUT” in the SPEAKER SET UP menu to
“PREOUT ONLY” (page 39).
