QLS QA100  Class T Digital Amplifier 100 W*2 (@4Ω) amplifier 24/192 TAS516

 

   QA100 is a true digital amplifiers, a stereo 100 Watt(@4Ω)amplifier with 5 single digital audio input.

   Traditional amplifiers input and process analog signals, which will generate various negative factors that may impact the sound effect, such as distortion, frequency attenuation and bad channel separation. QA100 directly process and amplify the input digital signals,The whole process mostly transits and processes digital signals with an anti-jamming capability higher than analog signals, It is this very reason why digital amplifier tends to generate better sound effects than analog amplifier.

   QA100 can automatically recognize and support 16bit and 24bit 32K-192K stereo PCM digital signal input. The asynchronous sampling rate conversion (ASRC) technology is adopted. Combined with high-precision temperature compensated crystal to reform digital clock, it can drastically reduce jittering of digital clock and provide signals with smaller noises, a larger amount of information and higher precision to the amplifier. In the meantime, impact of input digital signals on the acoustics is also reduced, which therefore drastically lowers requirement for the front sound source.
