Transistor Power Amplifier
1 PC HIFI Amplifier 30W Class A FET Single-ended PassA30 Whole Aluminum Casing Mono Design With upc1237 Speaker Protection High Quality Black
Model No: WHFTA-PassA30
It is a pure class A mono power amplifier, which is a very high degree of completion HIFI amplifier, its sound is silky smoothness, also it is too appealing when you listen to the sound of strings and human voice with the unit, and this is definitely a warm sound amplifier, but unlike a little dim sound of tube amp, its sound is warm and detailed, while low dive control and damping is also very perfect.
As its 30W output power at 30 square meters or below space, both with book shelf speakers or floor speakers, it will have a good performance. Remarkably, its signal to noise ratio control very well, you will hardly hear a little noise when you put your ear to the speaker at deep night, although its power is increased to 30W, but the circuit design more rational, so it is still have higher SNR.
1. Basic faithful to the classic PassA30 circuit, which, with respect to the sale of several million PassA5, merely reduces the output power, its structure is completely different, showing the maturity of its circuit!
2. 200W power supply high-quality Toroidal Transformer, using six pieces HIFI Nover 10000uf filter capacitors as CRC, total filtering capacity is 60000uf.
3. The most important is to add upc1237 speaker protection system, switch absolutely no impact sound while performing midpoint of DC protection, to prevent damage and burn your expensive speakers due to the amplifier circuit.
4. Three pairs of matched large power FET tubes expansion flow in parallel, to ensure the driving force.
5. Add a midpoint trimming circuit at differential input, which can correct the problem of midpoint offsetting at some extent.
6. The finished unit with about 2KG heat sink, while it is whole aluminum design, this benefit other parts of the casing become heat sink also in addition, so that the total heat dissipation area greatly increased.
7. As pure mono amplifier designing, it solve separation problem totally, as long as HIFI audiophiles have to understand what the benefits of doing so, the disadvantages are also obvious, is the high cost.
8. In addition to the standard RCA audio input terminal, the unit provides a balanced input interface; convenient to connect a professional preamplifier.
