This solid amplifier produces the characteristic Sansui Sound which made the Japanese brand so beloved in the 1970s. Simple, elegant design. Black front with round aluminium buttons. The Sansui AU 2900 is an integrated stereo amplifier with ample power (20 watts, both channels into 8 ohms, at 1000 Hz) and dramatically low distortion, clean tone characterise the most moderately-priced of the AU Series. Its design is also based on the true complementary OCL power circuit, with dual-transistor differential amp in the initial stage. Power output: 20 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 30kHz Total harmonic distortion: 0.3% Damping factor: 50 Input sensitivity: 2.5mV (mic), 2.5mV (MM), 150mV (DIN), 150mV (line) Signal to noise ratio: 70dB (mic), 70dB (MM), 85dB (line) Channel separation: 45dB (MM), 45dB (line) Output: 150mV (line), 30mV (DIN) Speaker load impedance: 8Ω (minimum) Semiconductors: 17 x transistors, 4 x diodes, 4 x IC, 1 x LED Dimensions: 400 x 120 x 240mm Weight: 6.3kg Year: 1975
