Marten - M•Amp Mono Power Amplifier

M-Amp là sự kết hợp giữa hai nhà thiết kế Leif Olofssom (chủ nhân của Marten Design) và Partik Bostrom (giám đốc AnaviewAB - Thụy Điển). M-Amp có thiết kế ngoài đúng chất Bắc Âu, đẹp và sang trọng, không cánh tản nhiệt, sử dụng vật liệu chrôm. Ampli này sử dụng công nghệ Class D AMS (Adaptive Modulation Servo) do chính Patrik Bostrom phát minh, cho hiệu suất cao, khả năng tái tạo dải tần cực rộng, cho âm thanh chi tiết và cực nhanh. Ampli có công suất 550W/kênh, nặng 45Kg.

 

Marten - M•Amp Mono Power Amplifier 

M•Amp Mono Power Amplifier is a joint venture between Leif Olofsson, chief designer of Marten, and Patrik Bostrom, founder of the design house Anaview AB in Sweden, now CTO of Abletec A/S. He developed a revolutionary new loop linearization technology called AMS (Adaptive Modulation Servo) that M•Amp is based on.

Using our revolutionary AMS technology, the M•Amp delivers a powerful, transparent, musical sound utterly free from distortion.

Marten - M•Amp Mono Power Amplifier

AMS (Adaptive Modulation Servo) was invented by Patrik Bostrom, founder of the design house Anaview AB in Sweden. The core of the Marten amplifier is an inverting globally self oscillating class d stage. This class d stage is a load independent wide bandwidth (-3dB @ 120 kHz) first order modulator, switching at 600 kHz, with a constant loop gain of 30dB all the way up to the switching frequency. The result is a true delay line, which displays very wide bandwidth and fast transient response.

The AMS is connected to the positive and negative inputs of the core amplifiers modulation stage, acting to eliminate the imperfections of the modulation. The gain of the core amplifier cannot be affected by the servo so the wide bandwidth first order behaviour of the class d modulator is perfectly preserved. The servo has flat 20dB gain up to 20 kHz, creating a constant linearity in the audio band.

Marten - M•Amp Mono Power Amplifier

To ensure no compromise to excellence is made, two independent channels are used in a balanced configuration.The result? A truly exceptional amplifier with a very wide bandwidth, ultra low noise/distortion, high output power and very low losses.
