QA100--Full Digital Stereo Amplifier

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

Page 2 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.
