Harman Kardon 75 Owners Manual - Page 18

SPECIFICATIONS AMPLIFIER SECTION Power Output: 45/45 watts, RMS, both channels driven simultaneously into 8 ohms, 20-20kHz at less than 0.5% THD at 120 volts, 50/60 Hertz AC. (In special double power stereo mode) 4x 18 watts, RMS into 8 ohms, 20-20kHz at less than 0.5% THD at 120 volts, 50/60 Hertz AC. ALL FOUR CHANNELS DRIVEN SIMULTANE- OUSLY. (Power measurements made by the most stringent and conservative standards. If measured by competitive standards, power would be 55/55 in stereo and 4x 23 in 4-CH) Power Bandwith: From less than 10 to beyond 40kHz into 8 ohms, all channels driven in stereo or 4-CH mode at less than 0.5% THD. Total Harmonic Distortion: Less than 0.5% at any power rating from 0.1 watt to full rated power. (Typically runs below 0.2% from 20-20kHz at full power output) Intermodulation Distortion: Less than 0.15% at rated output. Hum and Noise: Better than 85dB below rated output (unweighted) in stereo or 4-CH mode. Damping Factor: 40:1 at 4 and 8 ohms. Frequency Response: From below 4 Hertz to beyond 70kHz, -±0.5dB at normal power levels. From below 1 Hertz to beyond 100kHz at normal power levels. Square Wave Tilt: Less than 10% at 20 Hertz through phono preamplifier and power amplifier simultaneously. Square Wave Rise Time: Better than 2 microseconds. Stability: Absolutely stable with any type load. Phono Overload: Greater than 75 millivolts. Bass and Treble Tone ± 12dB bass boost and cut at 50 Hertz. Control Action: -±. dB treble boost and cut at 10kHz. TUNER SECTION FM Sensitivity: 2.0 microvolts, IHF. Ultimate Signal to Noise Ratio: 70db. Capture Ratio: 2.5dB. Image Rejection: -50dB. Spurious Response Rejection: - 78dB. Multiplex Separation: 35dB. Total Harmonic Distortion: 0.6% mono. 0.7% stereo. AM Rejection: -50dB. SCA Suppression: Totally inaudible. AM Sensitivity: 200 microvolts/meter. Image Frequency Rejection: Better than 55dB. IF Rejection: Better than 55dB. Selectivity: Better than 34dB. GENERAL Dimensions: 16%" W x 15' D x 5' H (less knobs)
