Sansui BA-5000


The Sansui BA-5000 is a stereo/mono power amplifier delivering a per channel power output of 300 watts, minimum RMS, both channels driven into 8 ohms over a 20 to 20,000Hz bandwidth with no more than 0.1 % total harmonic distortion.

A high-efficiency output transformer allows the BA-5000 to deliver full rated output at loads of 8, 4 or 2 ohms for 2-channel ultra-stable operation; a full 600 watts in mono. The output transformer also functions as a bandpass filter cutting subsonic signals to protect speaker cones.

Features include:

Temperature sensored cooling fan.

Three protection circuits : ASO (area of safe operation) detection circuit monitors and limits current flow in power transformers ; thermistor self-restoring temperature detection circuit; overload detection circuit with quick-acting fuses.

High-accuracy meters, with logarithmically compressed scale covering 0.01 to 300 watts and decibel scale ; precise, positive controls plus block diagram of instrument interior printed on cover.
