QLS QA661 Lossless Master Tape Player Fever Digital Turntable USB Sound Card
100% Brand New

QLS QA661 has a MCU architecture, supports WAV, FLAC, APE, DSD and other formats, built-in XMOS digital interface, word clock output, coaxial input signal purification function
Note: The word clock output only works for the internal player. When using the USB interface and external coaxial input, the word clock does not work (no output)


All items guaranteed 100% BRAND NEW in the original edition Box.


MCU single-threaded program architecture, remote control decoding is completed by another chip, high real-time, ultra-low Jitter to provide high-quality sound assurance.
QLS's next-generation zero jitter clock circuit uses a high-quality crystal oscillator together with an audio-dedicated PLL, and provides it with a high-quality clock power supply to ensure high-accuracy, low-jitter digital audio clocks.
Implementing the design concept of electricity as the mother of sound, using a new generation of power supply circuits, not only low noise, fast response, high ripple suppression, more importantly, the isolation and mutual influence of various power supply parts does not affect each other, ensuring the quality at the same time The background is dark, live, full and full of simulated flavor.
The whole machine design implements the ultimate fever theory. The power input socket uses Swiss Schurter filter sockets and comes standard with Swiss Schurter fuses, giving up the front power switch and the Standby function of the electronic switch that easily affects the sound quality.
The multiple separation and isolation methods are designed for multiple circuits in the machine, and a single machine is designed as multiple independent units to prevent the generation of digital sound.
Digital signal isolation uses the excellent digital audio transformer SC947-02 to ensure high quality and good sense of hearing.
Nuvotem Talema sealed toroidal transformers are used to ensure quality from the source of electricity.
In pursuit of extremes, the CMC fever RCA coaxial mount is used to ensure good electrical transmission performance.
The complex shock absorbers and shock absorbers are designed to ensure that the sound is extremely pure, extremely clean, and extremely solid.
Self-adsorption circuit, metal shield plate isolation, and housing processing are added to the free electron absorption circuit to ensure the sound is smooth and quiet.
Liquid metal filtering Multi-processing power and signals to ensure that the sound has sufficient density and layering.
Both the audio and main control boards use a 4-layer circuit board design to ensure complete ground plane and digital high-frequency signal integrity, while ensuring a low internal resistance of the power supply circuit.
The internal brands, resistances, capacitors, and other device brands and models do not compromise, ensuring that the overall design does not appear to be significantly short.
All functions of the software are based on the sound quality that will not be affected. We will not hesitate to cut off all formats or functions that affect sound quality.
Most of the raw materials are purchased directly from abroad. Although the price is more than domestic, it can ensure quality.
The aluminum panel remote controller has more quick control keys for quick search or positioning of songs, and at the same time, more humanized control.
Digital output: coaxial output, optical output, digital balanced AES/EBU output, word clock output. Each way can output at the same time and do not interfere with each other.
USB interface: The QA661 has an XMOS USB interface with a very high sound level.
