[. . . ] If connections are loose, there could be loss of sound or noise produced. Never attempt to connect two or more speaker cords to a single speaker terminal. Never short-circuit the + and - speaker cords. If the left and right speakers are connected inversely or if the speaker cords are connected with reversed polarity, the sound becomes unnatural with ambiguous acoustic image positioning. Be sure to connect the speakers and speaker cords correctly. 3 EN 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. 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: 3 Connect the amplifier as shown in the diagram. Preamplifier · For 2 speakers: Set the 2 (STEREO)/6 OVER switch to 2 (STEREO) and 6 OVER/2 switch to 2. · For 6-16 speakers: Set the 2 (STEREO)/6 OVER switch to 6 OVER and 6 OVER/2 switch to 6 OVER.

The amplifier's performance is not THX®-certified when the switch is set in the 2 (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. 4 EN 7Mono (bridged, or BTL) configuration In this configuration, the KMF-X9000's two individual channels operate together to drive a single speaker (such as a subwoofer) in mono. This allows the amplifier to deliver more than double the power of one of its channels to the 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: 3 Connect the amplifier as shown in the diagram. Except for Europe Note: Since bridged operation produces enough output power to pose a small risk of electrical shock from the speaker terminals, please attach the terminal cover as shown in the diagram below: KRF-X9995D DTS-ES DISCRETE 6. 1 MATRIX 6. 1 NEO : 6 PRO LOGIC SURROUND BACK 96kfs CD 2 / TAPE 2 CLIP MONITOR INDICATOR · For 6-16 speakers: Set the 2 (STEREO)/6 OVER switch to 6 OVER and 6 OVER/2 switch to 2. · Make sure to connect the audio input cable to the MONO/BTL input. When a monaural pre-out signal is to be connected, be sure to connect it to the MONO/BTL terminal. Audio cord (not supplied) Stereo mini-plug cord (supplied) For 12 V RELAY CONTROL, see page 6. Except for Europe Mount the supplied speaker terminal cover using the two screws that are attached to the unit. To wall AC outlet Subwoofers (6-16) 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. 5 EN 72-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 speakers: Set the 2 (STEREO)/6 OVER switch to 2 (STEREO) and 6 OVER/2 switch to 2. · For 6-16 speakers: Set the 2 (STEREO)/6 OVER switch to 6 OVER and 6 OVER/2 switch to 6 OVER. 3 Connect the amplifier as shown in the diagram. KRF-X9995D · Make sure to connect the audio input cable to the MONO/BTL input. When a monaural preout signal is to be connected, be sure to connect it to the MONO/BTL terminal. Audio cord (not supplied) Stereo mini-plug cord (supplied) For 12 V RELAY CONTROL, see below. * In the case of 2 In the case of 6 To wall AC outlet Subwoofers (2-16) (Right) (Left) * If you connect more than one pair of speakers to the KMF-X9000, move the 2 (STEREO)/6 OVER (THX) switch to the 2 (STEREO) position. The amplifier's performance is not THX®-certified when the switch is set in the 2 (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. 712 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. · Set it properly referring to "Connections". · Turn the power OFF, eliminate the short-circuiting, then turn ON the power again. · Turn the power OFF and wait until the internal temperature drops.
