140W Amplifier Circuit 2x 70 Watt

Stereo Power Amplifier is 2x70Watt STA550 chip audio power with BASH concept that can be connected with digital perangkkat. 2x70Watt STA550 Stereo Power Amplifier is an amplifier with BTL system with symmetrical power supply with ground. Power amplifier STA550 uses power output transistor which is on the chip and is set to produce a high efficiency audio power.
Power output on the STA550 is using the system without copling ac bridge (direct) and zero offset. Strengthening of the STA550 from stereo power amplifier is +12 dB. 2x70Watt STA550 Stereo Power Amplifier is equipped with temperature sensors for protection from overheating and current-limiting protection system for power amplifier. 2x70Watt STA550 Stereo Power Amplifier is equipped with standby and mute controls to regulate silent or active mode power amplifier.
