2-Channel mono configuration
In this configuration you can connect 2 speakers (such as 2 subwoofers) to the KMF-X9000 and send a single preamp signal (such as a
mono subwoofer output) to both speakers without using a Y-adapter. The amplifier delivers its rated stereo power output to each speaker.
1
Make sure that the KMF-X9000’s power cord is unplugged from the wall outlet before making any connections.
2
According 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.
3
Connect the amplifier as shown in the diagram.
• Make sure to connect the audio input cable to the MONO/BTL input.
* If you connect more than one pair of speakers to the KMF-X9000, move the 2
Ω (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 2 Ω (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.

12 V Relay power control
The KMF-X9000 can be powered on and off by a 12 volt trigger signal from a compatible component (such as the Kenwood
KRF-X9995D receiver).
1
Make sure that the KMF-X9000’s power cord is unplugged from the wall outlet before making any connections.
2
Connect the supplied mini cable to the KMF-X9000’s RELAY CONTROL input and the 12 V relay control output of the
KRF-X9995D or other compatible component.
• When the KMF-X9000’s POWER switch is turned ON, the amplifier will remain in the STANDBY mode (the STANDBY
indicator will be lit) as long as there is no signal at the RELAY CONTROL input.
• The KMF-X9000 will automatically turn ON when a 12 V signal is applied to the RELAY CONTROL input.
• When the 12 V signal is removed from the KMF-X9000’s RELAY CONTROL input, the amplifier will go back into the STANDBY mode.
• If there is no cable connected to the KMF-X9000’s RELAY CONTROL input, the amplifier’s STANDBY indicator will not
function, and its ON/OFF status will be controlled by the POWER switch.
