72-Channel stereo configuration
This is the ‘standard’ stereo operation mode, with the amplifier driving 2 speakers in stereo (such as the Surround Back Left and
Surround Back Right speakers in a THX Surround EX® home theater system). The amplifier delivers its rated stereo power output
into each speaker.
1Make sure that the KMF-X9000’s power cord is unplugged from the wall outlet before making any connections.
2According to the speakers to be used, set the speaker impedance selector switch as follows:
•For 2 Ω speakers: Set the 2Ω (STEREO)/6Ω OVER switch to 2Ω (STEREO) and 6Ω OVER/2Ω switch to 2Ω.
•For 6-16 Ω speakers: Set the 2Ω (STEREO)/6Ω OVER switch to 6Ω OVER and 6Ω OVER/2Ω switch to 6Ω OVER.
3Connect the amplifier as shown in the diagram.

* If you connect more than one pair of speakers to the KMF-X9000, move the 2Ω (STEREO)/6Ω OVER (THX) switch to the 2Ω
(STEREO) position. The amplifier’s performance is not THX®-certified when the switch is set in the 2Ω (STEREO) position.
Now you can plug the power cord of this unit into the AC outlet!
CAUTION:
Before reconnecting a speaker cord or switching a selector switch, turn OFF the power and unplug the power
cord to avoid malfunctions or damage to the unit.
