FIG dual-channel circuit LM378 dual operational amplifier composed of Europe. Supply voltage Ub 24V and 8 ohm load (or 16 Euro), the output power per channel 4W. Circuit with i
nternal current limit and thermal overload protection circuit cut off, etc., also has a power supply, which makes point bias voltage is automatically adjusted. In addition, it also has ripple rejection ratio, good channel separation characteristics, high input impedance and less external components and so on. Particularly suitable for the stereo, stereo tape recorders, FM/AM stereo audio power amplifier for the radio. The circuit has a separate input termination action is high, bass control to limit the high, bass control to give the greatest degree of improvement and off.
