USB-C Cable:
Coaxial Cable:
Connect the coaxial cable to an external DAC, to allow
the DX260MK2 to work as a digital transport.
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.
Clear TPU protection case:
Use the TPU protection case to protect the DX260MK2
chassis from scratches.
Screen Protector:
Use the screen protector to protect the DX260MK2
screen from scratches.
Warranty Card:
The warranty card will be requested at the time of
warranty repair. Please retain the warranty card.
Quick Start Guide:
This reviews the basic functions of the DX260MK2.
Balanced Burn-in Cable:
Plug the burn-in cable into the output socket and keep
playing music to burn-in the DX260MK2. The burn-in
process helps the DX260MK2 sound reach its full potential
by forming the capacitors and stabilizing the electronic
components used.

4
Tips for burn-in
The use of the 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 DX260MK2, 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 DX260
MK2 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.
