Note:
There are protective films on the front and back of Z4, please check,
To use 2.5mm and 4.4mm, you need to turn on the balance function in the DAC settings,please contact us if there have other question
Features:
1. Brand new CNC appearance.
Each Z4 comes from a hollowed out aluminum ingot. This appearance is a self-taught painting by Zishan without art foundation, everyone patted it. The volume is 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 the 44.1K sampling rate music format.
A 49.1520M crystal oscillator corresponds to the 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 balanced PO.
4.4mm balanced 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 decoding up to DSD256
Support common file systems of TF card such as NTFS, EXFAT, FAT32, support multiple partitions, no need to format.
5. Flagship Bluetooth function. Using the latest 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, you can easily 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 power consumption and performance pros and cons, and still uses 9V power supply, with 19 MLCCs with a total of 1900uF filter pool, which can meet the sudden change of current in large dynamic music.
8. Good dual ES9038Q2M DAC chip and TI OPA1622 headphone amplifier
Z4 contains two ES9038Q2M chips from ESS, which opens up multiple filtering functions of ES9038Q2M.
Containing 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.
Z4 coaxial output supports up to PCM384K DoP128.
