Dual Mono Drive (Function of the KAC-9152D) CENTER UNIT Remote controller f  , 2%-/4% ,).%/54  , 2%-/4% ,).%/54 g f g Subwoofer (2 Ω or higher) A Dual Mono Drive system is a system in which 2 monaural amplifiers are both set to bridged mode to drive one subwoofer with a high-output signal. Setting 1.If you use the connection as shown, set amplifier ¡ to the Forward phase (PHASE: 0 º) and set amplifier ™ to the Reverse phase (PHASE: 180 º). 2.Set all other switches (except for the "PHASE" switch) of amplifiers ¡ and ™ to the same position. Connection 1.Connect the 9 speaker wire to the 9 terminal of amplifier ¡. Also, connect the · speaker wire to the 9 terminal of amplifier ™. 2.Connect between · terminals of amplifiers ¡ and ™. 3.The remote controller can be used just when connected to amplifier ¡. It can be used for more fine control if also connected to amplifier ™. 2CAUTION • Always connect between · terminals of amplifiers ¡ and ™. If a cable is incorrectly connected between 9 and · terminals of these amplifiers, the amplifier protection circuit is turned on. • Use a speaker having the 2Ω or higher impedance only. • To protect the electrical system from a short-circuiting, be sure to remove the · battery cable from the vehicle in advance. • Fully insulate amplifier terminals and speaker terminals to avoid a high voltage from peripherals. 6 English
