Power amplifier Quad 405 MK 1

Quad 405 MK1 power amplifier Type Stereo power amplifier * Compensation value when both channels are driven simultaneously. Power and distortion factor (8 Ω load, sine wave input) 0.01% or Less (at 100 Hz, 100W output) 0.01% or Less (at 1 kHz, 100W Output) 0.01% or Less (at 10 khz, 100W output) Output internal impedance 3.3 μ H in series with 0.03 Ω Offset voltage 7 mv or less Frequency Response (1 kHz Standard) Low frequency : -1dB at 20 Hz High frequency : -0.1 dB at 20 Hz, -3dB at 50 kHz Input sensitivity 0.5 V (8 Ω Load, 100W Output) Input impedance 20k Ω / 220 pf Slew rate 0.1 V / μ s Maximum input limit If the input signal is up to + 20 dB, it will be restored immediately. Crosstalk (at 1k Ω input load) 80dB(100Hz) 70dB(1kHz) 60dB(10kHz) Signal-to-noise ratio -96dB (for A correction) -93dB (uncorrected) Protection circuit Electrically operated by current control circuit. The peak output current is limited to 8.5A, and the output short-circuit is limited to 3.1A. If both outputs are short-circuited simultaneously for an extended period of time, overheating may result and malfunction may result. Pwer 100 ~ 130 VAC / 200 ~ 250 V, 50Hz/60Hz Power consumption 30W ~ 350W (depending on input level) External dimensions Width 340.5x Height 115x Depth 195 mm Weight 9kg
