• Notes
• Stereo amplifier with 210 watts per channel into 8 ohms.
  2 Multi-LED output meters. Power output 210 watts minimum RMS per channel into 8 ohms from 20 Hz to 20 kHz with no more than 0,09 total Harmonic Distortion.
  Continuous power 260 watts per channel into 8 ohms @ 1000Hz; 360 watts per channel into 4 ohms @ 1000 Hz.
  Typical total harmonic distortion 0,09% @ rated power output into 8 ohms @ 1000 Hz; 0,09 @ rated power output into 4 ohms @ 1000 Hz. Intermodulation disiortion (60 Hz : 7 kHz = 4 : 1) less than 0,09 @ rated power output into 4 ohms.
  Frequency response 12 Hz to 40 kHz, + 0 - 1 dB. Signal to noise ratio 110 dB (IHF "A-weighted). Residual noise 120 microvolts (IHF "A-weighted"). Daming factor 1000:1 @ 1000 Hz. Input impedance 33K ohms minimum. Imput sensivity 1,0 Volt RMS @ rated power output. Speaker impedance: Will accept 4 ohm or greater speaker load. Slew rate better than 18 Volts/microseconds. Rise time (small signal) less than 4,0 microseconds. Phase shift 0 degrees @ 20 Hz lagging 18 degrees @ 20 kHz. Power requirements 60 Hz, 120 Volts AC (USA and Canadian models) or 100 - 120 Volts/220 - 240 Volts AC, 50/60 Hz. Power comsumptions 1200 watts (10 Amps) maximum @ rated output.
