Gain more depth with monaural amplification
Enjoy the tasteful sound quality of analog sound sources
Astro Electronics has renewed its lineup of high-grade amplifiers to all monaural specifications. Along with the shift to monaural amplifiers for stereo power amplifiers, monaural preamps have also been adopted.The main purpose of a mono preamplifier is to convert a stereo signal to mono and reproduce it without interfering with each other by dividing the signal into left and right.
Especially in the use of mono sound sources and playback of mono recordings,It provides proper coupling of mono signals for clear playback with minimal noise and interference. This allows you to enjoy the original quality of monaural sound sources.

The transformer uses an original transformer that pursues sound quality without compromise while keeping the price down. The input/output terminals are gold-plated high-grade terminals.
Many analog sound sources, such as analog records and analog cassette tapes, are in monaural format. You can use a monaural preamplifier to enjoy the tasteful sound quality of analog sound sources.
Audiophiles and enthusiasts may be obsessed with playing mono sound sources.The AST-2000MVIPSP is a key component to meet such demands.
The AST-2000MVIPSP can finely adjust the audio balance during monaural playback. The attenuator uses 41 contacts for more precise control.
The AST-2000MVIPSP provides optimal performance not only for stereo sound sources, but also for monaural and analog playback. It will be used to accurately reproduce the characteristics of monaural music and provide a rich musical experience.
