USB-C cable：
Coaxial cable：
Connect the coaxial cable to an external DAC, to allow the
DX300MAX working as a digital transport.
AC adapter (12V/1.5A)：
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 out from the 4.4mm
balanced line out port.Be aware that this cable is one
direction. It cannot be used for the output from a 3.5mm
port to a 4.4mm input.
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.
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 DX300MAX.
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 DX300MAX.
The burn-in process helps the DX300MAX'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 DX300MAX’s chassis
from scratches.
Screen protector：
Use the screen protector to protect the DX300MAX’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 DX300MAX.

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 DX300MAX, 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
DX300MAX 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 DX300MAX are
