L.Pass A30 Mos FET Single end pure class a 30W power amplifier amplifiers audio hifi channel | Электроника

Reminder： 1, the machine is a pure after the power amplifier, no volume control, must be used with the pre amplifier 2, the machine for a single channel design, the need for stereo, please buy 2 sets, be sure to pay attention to!   If you need MOS FET preamplifier,Please contact me!   Parameters: Maximum output power: 30W 1KHz continuous power without distortion. Distortion: 1KHz sine wave 30W output <0.01%; Input sensitivity: <2Vrms. Amplifier voltage gain: 11 times. Power supply voltage and maximum power consumption: <110W, AC220V Volume and weight: 280*212*90mm, 6.8Kg     The circuit characteristics of integrated design: Basically faithful to the classic PassA30 circuit 200W high quality loop cow power supply, the use of 6 fever 10000uf Nover CRC capacitor filter, the total filter capacity of a total of 60000uf, the most important: Join the upc1237 speaker protection system, switch machine is absolutely no impact sound, execute the midpoint of DC protection at the same time, eliminate the power amplifier circuit and burn your expensive box damaged. Three pairs of large power field effect transistor parallel flow output, ensure the driving force. In the differential input link to join a midpoint of the fine-tuning of the circuit, can be a certain degree of correction of the midpoint of the problem. Finished machine uses about 2KG of the heat sink, while the whole machine is aluminum design, the benefits of doing so is that in addition to the heat sink, the other parts of the machine is also involved in heat, making the total heat radiation area greatly increased. Pure post mono design, to prevent separation from the more, as long as the fancier, all understand what the benefits of doing so, disadvantages are also obvious, is the high cost. In addition to the standard lotus audio input, the machine provides a balanced input interface, easy to connect to the front end of the professional.
