IWISTAO HIFI Power Amplifier Class A FET Tube Single-ended 2 x 16W PassAm Circuit Whole Aluminum Casing Desktop
Model No: WHFFA-PA01
PassAm is a small desktop power amplifier, supper bass, and its high-frequency is too flavor, definitely not irritable, smooth like as silk in general; it is infective to listening to the sound of strings and human voice, and this is definitely a warm sound amplifier, whose voice is warm and delicate, while control power of low frequency and damping are also very perfect. Then there is remarkable controlled for noise of the unit, has come to the point of terror, you put your ear to touch the speaker may have a little noise when late at night.
1. Basic faithful to the classic PassAm circuit, merely reduces the output power to compare with expensive model PassA5, and its structure is completely same, showing the maturity of its circuit.
2. Per channel with four 10000uf to compose a CRC filter capacitor, total filtering capacity is 80000uf. The most important is, left and right channels have independent filtering circuit. Not only does it reduce the ripple further, but also it improves the overall separation fundamentally.
3. Added upc1237 speaker protection system, switch absolutely no impact sound while performing the midpoint of the DC protection, to prevent damaging the amplifier circuit and burning your expensive speakers.
4. Integrated volume control potentiometer link.
5. Added a trimming circuit in the mid-point differential input that can correct the problem for the offset of midpoint at a certain scope.
6. The unit used was 1kg heat sink approximately, and it is made of whole aluminum, its benefits are, the unit is also involved in heat radiation except heat sink, so that total heat dissipation area is increased substantially.
7. As a pure design, the chance to have a cooling capacity of more than 50 degrees outside, you should be prepared mind, this circuit is not nice if it is not hot.
1. Don't touch the amplifier when it works, there is high temperature on it because the amplifier works on Class A state.
2.The lead time of AC110V version is about 10 days. If you buy 110V version, it means you accept the term.
