ASTRO AST-300BMVIP/SP Monaural Power Amplifier

Astro Electronics has renewed its lineup of high-grade amplifiers to all monaural specifications. By converting a stereo amplifier to a monaural amplifier, you can obtain higher output power and deeper sound. It is especially effective in improving acoustic performance when driving loudspeakers with high loads. Depending on the acoustics and speaker arrangement of the room, the sound field may lack balance during stereo playback, but by integrating the outputs of both channels by making it monaural, a uniform and stable sound field can be obtained.Audio symmetry can be improved.

AlsoCompared to stereo amplifiers, which weigh a lot of full-size stereo amplifiers, the weight of each unit is reduced to less than half (compared to the company's ratio), so it is not to be overlooked that it is very easy to install and handle. The AST-300BMVIP is 5 cm narrower than the MVIPSP.

The transformer uses an original transformer that pursues sound quality without compromise while keeping the price down. The input terminals and speaker output terminals are gold-plated high-grade terminals.

 For self-biased capacitors, the AST-300BMVIP/SP uses a capacitor that is an order of magnitude higher than 4000 microns, compared to the capacitors used by general manufacturers with 200~400 micros. As a result, although it is self-biased, it has the same sound quality as the fixed bias. Replace a variety of 300B tubes manufactured by vacuum tube manufacturers around the world without hesitation to get the best performance.

In addition, the use of a UL connection increases the output power and contributes to improved sound transparency and resolution. The volume is controlled precisely by adopting a click-type 31-contact attenuator.
