Categories: Car HiFi Power Amplifier Mono
Product: Ampire MBM 500.1 (12 volt version of the MBM1.24V)
Power amplifiers that look small and harmless are often underestimated. The mono from Ampire's MBM series is the best example of this. It is packed with technology, countless components cavort on the circuit board, a suspicious number of which have more than three legs. The technicians have poured a lot of brainpower into this circuit in order to generate the necessary efficiency for performance, which makes such performance development possible in the smallest of spaces. Of course, a Class D circuit is used, and Ampire has put a lot of thought into a clean signal. The output filtering is carried out very carefully, which leads to quite successful distortion measurements despite the digital technology. You don't have to worry about performance with the 500.1, 276 or 450 watts make even adult woofers tremble. The equipment also earns great praise, there is even an adjustable bass boost, and the extremely useful automatic switch-on for operation on the factory radio is also on board. In the listening check, the little Ampire comes out as a powerful subwoofer tamer, she also shines with enormous control. Even with more demanding bass passages, it maintains an overview. In addition, she can impressively stage firmly kicked kick drums, and very well provide them with dry punch. A performance that is quite inspiring, so that the MBM 500.1 truly deserves an award.
