QA360 is based on selling high-end player Qianlongsheng same platform QA860 portable products, its near-perfect hardware and software architecture and excellent sound quality performance called concentrated small desktop PC, is a major selling point to the quality of music playback fever device. It has the power QLS latest processing technology, superior real-time software architecture, zero Jitter clock and digital processing circuits, unique isolation filter design, from Qianlongsheng sound radical innovation to noise from absorbing circuit.
starting from the source to ensure HiFi — using high-end desktop architecture same digital player
have compared the different digital players, compared the different digital interface Shaoyou should be emotionally sound digital audio output can be very different, and little more influence on the whole system is not better than decoding brings.
QA360 Player Digital section continues to QA860, still using QLS-HiFi exclusive patented technology — threaded microcontroller pure tone player. Unique program architecture enables digital output with very low clock jitter (Jitter), while design draws QA360 QA860 QA660 and some design experience, though limited by the size and power can not achieve such a high-end desktop player QA860 level, but than many consumer programs using ARM or making the player is there to enhance the level. (As we do with the DVD digital output interface then your decoding can not compete as a CD, because the source has become the biggest bottleneck)
QA360 can play 24Bit / 192KHz high rate of WAV digital audio stream, we know that the traditional CD-ROM only 16Bit / 44.1Khz, the amount of data 24Bit / 192KHz digital mastering of data than a traditional CD 5-8 times (a First 24Bit / 192Khz mastering songs almost the entire capacity of a CD), the digital mastering both in the sound field, density, dynamic and resolving power and so far more than conventional CD quality.
QA360 support DIFF and DSF file (DSD64, 1bit, Stereo) direct playback and also supports direct playback SACD ISO image file, direct hardware DSD decoding output analog signal (DSD package ISO can support, but DST is ISO compression package not supported).
Clock – Digital Audio Soul, QA360 double + One unique crystal design
Clock is blood digital circuit, digital audio, sound quality is the soul!
QA360 the desktop HiFi top player double + One Low Jitter TCXO crystal introduced QA360 portable audio player, audio sampling rate problem perfect solution to achieve a perfect sample of each bit rate and DSD audio source.
QA360 using 3-way Japanese custom ultra Jitter TCXO for the whole audio provide primary MCLK.
Because of the high bit rate music, there are two octave sampling rate, namely 44.1KHZ and 48KHZ multiples, for audio protocol, it requires a master clock is different. DSD is to use 176.4Khz same master clock, but we experiment found that the same process logic control clock DSD data will affect the sound quality, in order to achieve the most perfect HIFI sound quality, we use the third satellite Low Jitter TCXO.
Clock Low Jitter is important to ensure that the clock power supply, high-frequency response is fast enough and clean power is the basis for many products is to spend the expensive crystal, seemingly perfect design, but the clock with the host and with the same a power supply, or power is not very serious isolation and filtering pollution power to bring the number of multiple times the clock phase noise, so low Jitter only appears on the clock manufacturers specifications.
affect the sound portable player biggest bottleneck: — electrical power to the sound of the mother
quality of power supply has to sound decisive impact sound performance, power supply systems if they are ignored, the sound is absolutely impossible to reach the top.
The power supply of two key elements of the most important is the amount of current and purity, sufficient current to allow the equipment to issue dynamic abundant sound, if the current shortage, the sound will be muffled sound, frequency response open, dynamic out do not come; and clean power is to reduce noise and sharp sense of hearing on.
generally good desktop HIFI power part of the proportion of products will reach or exceed 40% of the machine, some foreign power on the desktop name part of the area occupied / cost is up to 50% -70% of the whole machine.
Power section QA360 proportion in two PCB board space up to 50% material cost power supply section of the proportion of all electronic materials are also over 50%.
portable space is the biggest limitation, if we want to allow more processing section to the power supply in a limited space, then the other part is bound to need to make some give way; for example, we have had two CS4398 contrast in mono mode, have been compared with two high-end single op amp amplify both channels, contrasting collected from the DAC to the LPF and then two channel differential amp fully independent processing and amplification, but can not bring much to enhance compensate for the lack of space caused by the processing circuit to reduce power degradation of sound quality. Power became the shortest piece of wood, we have to set aside more space to the power supply section, the shortest plank lengthen this fast.

QA360 volume control volume control using high-end desktop PC architecture perfect solution about balance and digit loss
analog potentiometer to adjust the low-end fine enough so that highly sensitive earplugs difficult transferred to a suitable volume, about imbalance biased tone, almost become incurable.
digital volume will be compressed to reduce the number of bits, a small volume of heavy losses signal conversion accuracy, and is beyond doubt.
PGA2311 is a frequently occurring in tens of thousands of HiFi equipment abroad volume control chip, is a top-level volume control chip, can be programmed to control the amplitude of the analog output of the amplifier, volume control purposes, to note that it is not a traditional sense of the digital volume control, it is a completely analog potentiometer with programmed control, the control steps of 0.5dB, the control range is + 31.5Db to -95.5Db, that is the maximum you can have 255 scale, adjust indeed fine enough, what headphones can easily find the most suitable location volume. Left and right balance of +/- 0.05dB, compared to factory quality standards set for the balance 3dB +/- ALPS potentiometer can be used up tall enough to describe. Of course PGA2311 original bulk orders containing tariffs Price $ 8.00 USD (plus related peripheral more than 10 US dollars) to the less than $ 1 for each of the ALPS 09 type potentiometer on tall enough.
QA360 use PGA2311 for volume control, and to PGA2311 pure enough to ensure sufficient supply of good sound performance.
perfectly restore each music, Music on Hold, vivid and original musical, sounds relaxed, full of atmosphere, clean, transparent, open sound field, extending both ends of the excellent, high-quality but also sufficiently resistant to listen.
With digital coaxial and digital optical output can be used independently as a digital turntable.
