SMSL M9 AK4490 32bit/768kHz DSD512 HiFi DAC Decoder+Balance Headphone Amplifier


M9 HIFI user oriented reference level of high-performance decoder,rich digital input interface: USB/fiber/coaxial, external power adapter 5 v external interference,reduce the circuit straight back with balance circuit output (mm) and 6.35 2.5 (mm) headphones mouth two choices,bring out the best in each other.

RCA output carefully designed to switch in the menu:fixed output level or the output mode.

USB digital interface,adopted the advanced XMOS asynchronous processing module,PCM and DSD can transmit the high music file format,especially the Windows operating system,using an ASIO Native drivers, can support DSD512 bit(1/M)decoding,with real DSD data stream sent to the D/A chip,decoding,MAC system free driver,output can be set to 32bit/768 KHZ,plug and play.

Is particularly pointed out that XMOS processing module through tieline,can receive from mobile phones and the digital signal,realizes the PCM and DSD hd decoding.Apple system using 20 to USB Camera Adapter line,the android system USES OTG line.

2 slices decoding chip adopted AKM company high-end AK4490,its excellent performance and with floating point arithmetic of digital filter and rich options,more for the professional equipment use.
Optical fiber and coaxial input support to 192 KHZ,excellent decoding part to ensure the high-fidelity sound,convenient external with digital signal output of a CD player or rotary table.

Power supply part of the inheritance of traditional HIFI equipment,audio use special electrolytic capacitor,we in the tuning process,in a fever of different capacitance,finally chose the capacitance,guarantee the musicality.

Headphone output part adopts 2 slices TPA6120,8-600 headset can deal with,have the balance (2.5 mm)
And the balance(6.35mm)two output modes.

Use the imported high-precision clock circuit,special high precision regulated power supply,time base error,DAC part distortion to 0.0004%,so the decoded signal balance three sections of high resolving power,accurate positioning and density,dynamic,sound field well,simulate the flavour is dye-in-the-wood,string,symphony,rock,classical,pop,etc all kinds of music are very appropriate,both the depth of the bass diving,elastic,and intermediate frequency of charming,sweet and high-frequency exquisite and elegant.

It is recommended to use the playback software:
MAC:Audirvana plus
Apple mobile phone and the device:HF player
The android mobile phone and PAD:seashells player

Low design architecture:
DAC AK4490 x 2
EVOL PGA2311 x 2
HPA TPA6120A2 x 2
OPA OPA1612 x 5
Low sampling rate of PCM support to 768 KHZ,DSD512 hard solution;
Low support native DSD decoding;
DAC use two pieces of AK4490,HIFI fidelity and full balance;
Low output part adopts two Texas Instruments company's senior headphone amplifier IC TPA6120A2;
Built-in frequency asynchronous rise,eliminate clock jitter;
Design is 2.5 mm equilibrium output,convenient to balance the earplugs,can through tieline pick four core card nong balance headphones;
Low audio part use 2 of the low phase noise crystal vibration;
Low and high precision CNC aluminium shell!
