1. Brand new CNC appearance.
Size: 57*98*20mm. The battery is 4200mAh. The battery life is 8 hours or more.
2. Adhere to the independent dual crystal oscillator + CPLD I2S solution
A 45.1584M crystal oscillator corresponds to a 44.1K sampling rate music format.
A 49.1520M crystal oscillator corresponds to a 48K sampling rate music format.
If the clock is not correct, the concert will “shift”, although not everyone can hear it, but this is a basic HIFI requirement.
3. Complete audio output interface
3.5mm single-ended LO.
3.5mm single-ended PO.
2.5mm balance PO.
4.4mm balance PO.
4. Support 10T TF card, compatible with most music formats and file systems on the market
Support playing APE, FLAC, WAV, MP3, OGG, M4A, WMA, AIFF, ALAC, AAC, DSF, DFF,
Lossless/lossy formats such as ISO, CUE, and even multi-channel DTS cover most of the music formats on the market.
Analyze CUE and ISO in seconds.
PCM up to 384k 32bit
DSD hard solution up to DSD256
Support common file systems of TF card such as NTFS, EXFAT, FAT32, support multiple partitions, no need to format.
5. QCC5125 Bluetooth 5.1 module.
At the same time, it supports APTX-HD or LDAC protocol, which adds lower latency aptx-ll protocol compared to CSR8675. Bluetooth LDAC mode supports up to 96K 24bit.
6. Mainstream DSD Native USB DAC function. Compatible with Amanero Italian digital interface USB DAC solution
The USB DAC solution is ATSAM3UxC, and Zishan rewrote the CPLD code to adapt to Z4.
The driver is compatible with Amanero Italian digital interface. Linux, MAC, mobile phones do not need to be driven. Windows driver download address: //amanero.com/drivers/setupuac2.exe
Computer music software foobar2000, QQ, etc. can choose DSD: WASAPI (push): speaker (Combo384Amanero) Fixed 32-bit output as a USB decoder, which can conveniently support PCM 384K, DSD256.
The USB DAC port of Z4 is an independent pure data port and does not take power, which means that when Z4 is connected to a mobile phone as a USB DAC, it will not consume mobile phone power.
7. The op amp provides a total of 9V and 18V power supply.
Zishan balances the advantages and disadvantages of power consumption and performance, and still uses 9V power supply, with 19 MLCCs, a total of 1900uF filter pool, to meet the sudden change of current in large dynamic music.
8. Dual ES9038Q2M DAC chip and TI OPA1622 headphone amplifier
Z4 includes two ES9038Q2M chips from ESS, which opens up multiple filtering functions of ES9038Q2M.
Contains two TI OPA1622 amp chips, multiple incense burners and multiple ghosts. I believe that the simplest and indispensable DAC+LPF+ amp design can play their respective performance without causing additional interference.
9. The coaxial output supports DoP (need to cooperate with the Z4 expansion board introduced later)
Simply put, it means that the DSD signal is transmitted through the coaxial cable. But at the same time, you need the decoder to support the DoP function. If the decoder DAC in your hand is a DoP-supporting decoder such as ES9038 or mojo, when you use the coaxial connection Z4 to play DSD Real DSD signal transmission and playback can be realized when music.
The Z4 coaxial output supports up to PCM384K DoP128.
