If curtain or a piece of paper is attracted by the air intake, the internal temperature will rise and protection circuitry will be activated. In this case, the sound will not be output. Connections Make connection as shown below. When connecting the related system components, refer also to the instruction manuals of the related components. Do not plug in the power lead until all connections are completed. 7 Connections of speaker cords For U.S.A. Connections of speaker cords CAUTION: 1 Strip coating. 2 Loosen. 3 Insert. 4 Secure. If the unit is used in the U.S.A., please read the supplement to the operating instruction entitled “Connection of speaker cords”. Warning! Particular attention must be given to making good electrical contact at the amplifier-output and speaker terminals. Poor or loose connections can cause sparking or burning at the terminals because of the very high power that the amplifier can deliver. Connection of banana plugs (Except for some countries, like Singapore, etc.) 1 Secure. 2 Insert. • Sound will not be heard if the speaker terminal is not fully secured. CAUTIONS: • • • • Connect all cords firmly. 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 7 2-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: • 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.
