IWISTAO HIFI Power Amplifier Pure Class A 2X8W Combined Headphone Amp Desktop Black 1969 Circuit Whole Aluminum Case Audio
This is a Pure Class A Desktop amplifier combined with headphone amplifier, its midrange and high-frequency is very musical mellow taste, absolutely no frizz, and it has high infectant power to listen human voices and other strings, also this is definitely a warm sound amplifier, warm and detailed, while the control of low frequency diving and damping is also very perfect. Further, its signal to noise ratio is remarkable, noise is hardly to be heard when you put your ear to the speaker at deep night. Adopted DC 24V supply voltage, its quiescent current is raised to about 1A, to ensure that its measured output power per channel achieve 8W.
1. Based on the classic 1969 a circuit that can be popular over half a century, still let the fans loved that explains where her unique beauty lies!
2. Used 5A relay to switch speakers and headphone output, this can be done via buttons Sel of the front panel.
