USB-C cable：
Coaxial cable：
Connect the coaxial cable to an external DAC, to allow the
DX320MAX working as a digital transport.
AC adapter (12V/1.5A)：
Use this AC adapter to charge the battery of the analog
section.
Connect the USB-C cable to a computer for charging,
data transfer, and USB-DAC function.The USB-C cable
can also be used with a USB charger to charge the
battery of the digital section.
Leather case：
Use the leather case to protect the DX320MAX’s chassis
from scratches.
Screen protector：
Use the screen protector to protect the DX320MAX’s
screen from scratches.
Balanced burn-in cable：
Plug the burn-in cablinto the BAL output socket, and keep
playing music to burn-in the DX320MAX. The burn-in
process helps the DX320MAX's sound reach its full
potential by forming the capacitors and stabilizing the
electronic components used.

Warranty card：
The warranty will be requested at the time of warranty
repair. Please retain the warranty card.

Tips for burn-in
The use of the burn-in cable is very straightforward. The
burn-in cable is used to form the capacitors and to condition
the rest of the circuitry. The method for burn-in is to use
normal resolution music, as higher resolution causes more
heat due to the higher demand on the system. Also, use a
normal listening volume, as the higher volume will have a
higher power consumption therefore more heat will be
generated. While burning in the DX320MAX, both the
balanced and the single ended components are being
affected and burned in.
The burn-in time can be from 100 to 200 hours and the
burn-in doesn't have to be continual. You can power off the
player and continue the burn-in process after a few days. It
is also not mandatory to use the burn-in cable, we supply it
as a convenience for when you are not listening to the
DX320MAX and you would like to get your dap conditioned
as soon as possible. You can also just listen to the player
and enjoy the music as your player goes through this process
while playing through IEMs or headphones.

Main Features
-The digital and analog sections of the DX320MAX are
powered separately, with each having an independent
charging system. The digital and analog hardware and signal
communications, adopt optocouplers and I2C isolators to
completely isolate the digital to analog sections from any
interference.
-The AMP section is powered by a true +/- 8.4V battery
pack. No voltage boost is used, which ensures the highest
purity and current output.
-An optimized super class A discrete amp circuit, which
eliminates the switching distortion of transistors, while
providing the sound signature of a class A amplifier, that
also significantly reduces heat generation, is used.
-The DX320MAX has versatile outputs that incorporate a
4.4mm balanced phone out/ line out, and a 3.5mm single
ended phone out/ line out.
-The voltage output of the 3.5mm single ended is up to 4.5V
RMS and the balanced phone output is up to 9V RMS.
-Electrolytic capacitors and film capacitors are used in the
DX320MAX.
-A custom analog 4 section stepped attenuator that has less
than +/-0.1dB channel tolerance imbalance, has been
selected.
-Quad BD34301EKV DAC Chips are incorporated.
-Bit for Bit playback with support up to 32bit/768kHz.
-Support of Native DSD up to 512x.
-5.0" IPS screen (1080*1920), with On Cell capacitive touch
panel.
