Luxury & Precision P6 64GB PCM1704K R2R DAC Portable Music Player DAP

DescriptionThe originalThe whole machine is equivalent to the use of 2 PCM1704K chips ideal dynamic SNR 118dB.The modifiedThe whole machine is equivalent to the use of 4 PCM1704K chips ideal dynamic SNR 120dB. Increase circuit area accommodate more resistors and components improve hearing and dynamics.All newThe whole machine is equivalent to 8 PCM1704K chips ideal dynamic SNR 123dB Bluetooth audio with protocol stack more FPGA LUT. Improved listening and dynamics improved operability and ease of use increased and optimized Bluetooth audio.Full resistance network discrete R2R DACInnovative 24 Bit full resistance network discrete R2R DAC portable player.One over ten thousandHundreds of one-millionth of a resistor carefully selected to form a discrete R2R DAC network.R2R the beautiful sound can also burstThe whole machine is equivalent to using 8 PCM1704K chips in parallel for ideal dynamics and R2R the beautiful sound can also burst.0 background noiseThe SNR of the whole machine is higher than 123dB 0 background noise and good news to low resistance balanced armature earphones.Simple non-touch operating systemLess interference less power consumption leaving more power for artificial circuits.Optimize Bluetooth with protocol stackA normal Bluetooth clock is a clock that is recovered after parsing data received wireless. The Bluetooth clock of P6 is directly generated by the stop-moment crystal vibration of P6 processed by FPGA and then the parsed audio data is aligned to the accurate clock generated by FPGA and sent to DAC for lower jitter.Volume control systemSelf-developed lossless - electronic switch matrix volume control system lower signal loss easier to use.The original sound reproductionFull resistance PCMDSD native decoding original sound reproduction.Architecture advantages sound characteristicsBecause of the advantages of the R2R architecture and the flexibility of the discrete components the sound of the P6 can be particularly fresh and natural delicate and mellow.Sound is the whole pursuit of P6Although the thrust is great it is particularly friendly to the earphones. In particular it enhances the control of the balanced armature earphones while meeting the demand of high output current and it also needs to achieve a natural stretch of hearing.SpecificationModel: P6Dimensions/weight: 124x67.3x20mm/248gDisplay 3.5-inch IPS screen resolution 480x320Body material: aviation aluminumRear cover: glassMain control: 1812CDAC: Fully discrete R2R decodingCrystal oscillator: Low phase noise -160dB active crystal oscillatorOp amp: EXCELS V-OAmp: EXCELS EP-AInductance: low internal resistance large current metal alloy inductanceButton: ALPSCapacity: 64GB 24 Bit ECC FLASHSupport extended capacity: 512GB micro SD card (TF)
