QA100 Full digital stereo amplifier is a bold essay in the HiFi amplifying field by QLS’s talent engineer team. Instead of using a traditional DAC and an analog signal amplifier, QA100 amplifies 2-way digital signals from CD/DVD players, computers and digital music players directly, and the amplified digital signals then pass through 2-way passive LPF circuits to drive the stereo speakers. Because of cutting off the traditional DAC and analog amplifying elements, QA100 provides a way to reduce the TCO of your HiFi system significantly.

QA100 is able to drive 4Ω@100W-8Ω@60W2 way bookshelf and floor standing speakers smoothly with accurate, transparent, high dynamic range and excellent transient response sound style.

QA100 implementsan ASRC circuit working together with a high-precision, low jitter and temperature compensated crystal to reform the sampling clock,therefore provides the ability to improve the sound quality of the low or mid-end source equipment remarkably.

QA100 designed as open loop digital circuits, thus there is no stable problem even in driving speakers with very low impedance. Moreover DSP technology is employed to correct the expected deviation on the final outputs that made a significant improvement for the amplifier’s line output characteristics.
