  • Page 7 WARNING: Due to the extremely high power output of the M-1500/2000 when used in Bridged mode, be sure to use only loudspeakers sufficiently rated to handle the resultant wattage (in Bridged mode, these must be 8-ohm speakers).

  • Page 8: Protection Circuitry

    To guard against this problem, make sure the M-1500/2000 receives adequate ventilation on all sides and that both the front and rear panels are unobstructed. - SEVERE OVERCURRENT CONDITIONS This occurs whenever the signal being input to the M-1500/2000 rises to a level above 20% THD (Total Harmonic Distortion). - SHORTED SPEAKER CABLES This will occur if, due to faulty wiring, the hot and ground signals being output by the M-1500/2000 short one another.

    Speaker Impedance Speaker Impedance M-1500/2000 series amplifier has three operating modes: Stereo, Bridged and Parallel and allows you to connect multiple speaker systems in parallel. Therefore, the minimum speaker impedance various depend- ing on the combination of these speakers. Be sure that the speaker impedance falls below the specified impedance.

  • Page 12: Caution For Speaker Connection

    The output capacity of your amplifier is very high: 1000W+1000W (4Ω) in stereo and 2000W (8Ω) in monaural on the M-2000: 750W+750W (4Ω) in stereo and 1500W (8Ω) in monaural on the M-1500. Be sure to use a speaker system that has sufficient input capacity.
