A beautiful set of Van Medevoort monoblock amplifiers, each with a power output of no less than 300 watts (unconditionally stable!) in class A. The vM PA330 are mono power amplifiers, featuring two separate power supplies. Each amplifier has its own power transformer, rectifier, and electrolytic capacitors. The main advantage of this is that no interference can occur between the left and right channels. Cross-channel power degradation, as well as interference and crosstalk, are eliminated. No ICs are used, so crossover distortion does not occur. In a standard or conventional class A amplifier, the operating temperature varies because the power output during music playback is not constant. This is not a problem if the speakers utilize most of the available energy for sound reproduction. However, at low power settings, the operating temperature in the output stages of this type of amplifier will rise, negatively affecting its technical performance and lifespan. Van Medevoort has solved and controlled this problem with the vM dynamic class A setting, which is directly controlled by the music signal itself. Heat generation in the power amplifier is no longer dependent on varying signal levels, whether high or low. With a strong signal, the quiescent current (or BIAS) is high, and there is almost no heat or shy generation because the speakers consume most of the energy. With a weak signal, a lower quiescent current setting is automatically applied without unnecessary heat or shy generation: the heat dissipated by the output stage remains constant. The output transistors, in particular, can now operate optimally at an ideal constant operating temperature. This also helps guarantee long-lasting quality and a stable sound image for many years. The input circuit of the power amplifiers is set to static class A.\u003c\/p\u003e\n\n\u003cp\u003e- power: 300 W - distortion: 0.002% 1 Hz - 100 kHz - power bandwidth: 1 Hz - 100 kHz - damping factor: 1200 - 1500 - input voltage: 1.5 V eff. 440 W - input impedance: 100 kOhm - signal\/noise ratio: -106 dB - short-circuit protection: 10 minutes - minimum load impedance: 0.1 Ohm - stability: unconditional - power supply: 230 V\/ 50 Hz - power consumption: 50 W min. 450 W max. - enclosure: steel - weight: 11 kg each - dimensions (incl.): 43 4x80x335 mm (wxhxd) - finish: black (satin)\u003c\/p\u003e","brand":"Van Medevoort","offers":[{"title":"Default Title","offer_id":59370672030041,"sku":"2163","price":890.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/van-medevoort-pa-330-1.jpg?v=1789118820","url":"https:\/\/wenwaudio.com\/en-eu\/products\/van-medevoort-pa-330","provider":"W\u0026WAudio","version":"1.0","type":"link"}
