operations.
Check speaker wiring and reconnect if
necessary. (See pages 6 and 7.)
Press SPEAKERS ON/OFF 1 and
SPEAKERS ON/OFF 2 correctly.
(See page 19.)
Select the correct source for the main room.
Press MUTING to cancel the mute.
(See page 21.)
Select the correct input mode (analog or
digital). (See page 31.)
Check connections. For analog corrections,
see page 7. For digital corrections, see page
10. For USB connection, see page 11.
Check speaker connection and reconnect if
necessary. (See page 14.)
Set the main/sub setting for the speakers
correctly to use them as the sub-room front
speakers. (See page 27.)
Turn on the amplifier.
Select the correct sub-room source.
Press MUTING to cancel the mute.
(See page 26.)
Check connections. For analog corrections,
see page 7. For USB connection, see page 11.
Check speaker connection and reconnect if
necessary. (See page 14.)

room.
Deactivating the sub-room sound will allow
you to use the Surround in the main room.
This is normal, not the malfunction of the unit.
Selecting different sources for the main room
and the sub-room will avoid these troubles.
If this happens, perform the same operation
again.
Connect the cable to the AM (H) terminal on
the rear panel.
