Analogue Amplifier Amplifying analogue signals, signal deterioration may occur. 1-Bit Digital Amplifier Amplifying 1-bit digital signals, signal deterioration is minimised. There is a considerable difference between amplifiers that process analogue signals and those that process digital signals. Analogue signals transmitted and amplified by analogue amplifiers suffer signal noise and degradation due to their nature. 1-bit amplifiers, however, transmit and amplify a pure 1-bit digital signal generated by a 7th-order (delta-sigma) modulation 1-bit A/D converter. Processing digital rather than analogue signals, 1-bit amplifiers virtually eliminate the sound deterioration that plagues analogue amplifiers. By taking full advantage of digital technology, 1-bit amplifiers achieve high-quality, stunning sound.
