USB-C cable：
Coaxial cable：
Connect the coaxial cable to an external DAC, to allow the
DX220Max working as a digital transport.
AC adapter (18V)：
Use this AC adapter to charge the battery of the analog
section.
4.4mm balanced to 3.5mm single ended cable:
CA02 2.5mm balanced to 4.4mm balanced adapter:
To output a 3.5mm single ended line from the 4.4mm
balanced line out port. Be aware of that this cable has
direction. It cannot be used for the output from a 3.5mm
port to a 4.4mm input.
Connect the Type-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.
To convert a 2.5mm balanced plug to a 4.4mm balanced
plug. The furnished burn-in cable is 2.5mm. Therefore,
please use this CA02 with the 2.5mm balanced burn-in
cable when you want to burn-in the DX220Max.
Balanced burn-in cable：
Plug the burn-in cable with the CA02 into the BAL output
socket, and keep playing music to burn-in the DX220Max.
The burn-in process helps the DX220Max's sound reach its
full potential by forming the capacitors and stabilizing the
electronic components used.

5
Leather case：
Use the leather case to protect the DX220Max’s chassis
from scratches.
Screen protector：
Use the screen protector to protect the DX220Max’s
screen from scratches.
Warranty card：
The warranty will be requested at the time of warranty
repair. Please retain the warranty card.
Quick start guide:
This reviews the basic functions of the DX220Max.

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 Max, 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 Max
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 DX220MAX 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, based on
the AMP8 module, 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 MAX has versatile outputs that incorporate a 4.4mm
balanced line out, 4.4mm balanced phone out, and a 3.5mm
single ended phone out. The voltage output of the 3.5mm
single ended is up to 4.4V RMS, and the balanced phone out
is up to 8.8V RMS.
-Kemet polymer tantalum, Toshin UTSJ, Panasonic, Nichicon
Audio Electronic, Amtrans PET film capacitors are used in
the MAX.
