CONNECTIONS
■ Connecting to an external amplifier
If you want to increase the power output to the speakers,
or want to use another amplifier, connect an external
amplifier to the PRE OUT jacks as follows.
• When audio pin plugs are connected to the PRE OUT jacks for
output to an external amplifier, it is not necessary to use the
corresponding SPEAKERS terminals. Set the volume of the
amplifier connected to this unit to the maximum.
• The signal output through the FRONT PRE OUT and CENTER
PRE OUT jacks are affected by the TONE CONTROL settings.
• Signals will only be output from the FRONT PRE OUT jacks
when SPEAKER A is turned off with ZONE B selected for SP
B SET (see page 57).
1 FRONT PRE OUT jacks

2 SURROUND PRE OUT jacks
Surround channel line output jacks.
3 CENTER PRE OUT jack

4 SURROUND BACK / PRESENCE PRE OUT
jacks
Surround back or presence channel line output jacks.
5 SUBWOOFER PRE OUT jack
Connect a subwoofer with built-in amplifier, such as the
YAMAHA Active Servo Processing Subwoofer System,
to this jack.
• Each PRE OUT jack outputs the same channel signal as the
corresponding speaker terminals. However, when both surround
back and presence speakers are connected to this unit, the
channel of the signals output from SURROUND BACK /
PRESENCE PRE OUT jacks may not correspond to the
location of the speakers connected through SURROUND
BACK / PRESENCE PRE OUT jacks.
• Adjust the volume level of the subwoofer with the control on
the subwoofer. It is also possible to adjust the volume level by
using the remote control of this unit (see “Manually adjusting
speaker levels” on page 45.).
• Some signals may not be output from the SUBWOOFER jack
depending on the SPEAKER SET (see page 49) and LFE
LEVEL (see page 51) settings.
