decode, possibly causing slowdowns in the player UI. You may convert such APEs to FLACs or
uncompressed WAVs using programs such as foobar2000 on the computer first to make it easier on
the player. The sound quality will be the same.
b) Playing high bitrate files or DSD files from slow micro SD card may cause stuttering. Class 10 or
above genuine micro SD cards are recommended.
c) As far as Android devices go, the X7 is a device with modest processing resources. Although the OS
has been deeply customized for uninterrupted audio performance, this can be compromised if too many
unrelated apps are installed and run in the background. You may try uninstalling any unnecessary apps;
alternatively, try using Pure Music mode (Section C.1) to play music stored on the X7 or DLNA networks and
switch to Android only when other operations are desired.
Why does the X7 get a little hot in operation?
A: The X7 utilizes an SoC with high clock speed, a separate DAC, and (also separately) a high power headphone
amplifier and independent analog volume control in the amplification stage, thus dissipating way more power
than consumer DAPs typically performing computation, DAC and amplification all on the SoC. Apart from
outputting more power to your headphones, a lot of this power is also dissipated as heat, thus causing the X7 to
heat up slightly in operation; but this does not endanger the X7 or the listener in any way.
Why can’t I go to the homescreen by pressing the home button?
A: Please check the X7 operation mode you are currently in by pulling down the settings menu from the
upper right of the touchscreen. If you’re in Pure Music mode, tap on its icon to reboot in Android mode
to view the Android homescreen.
Why can a click be heard inside the X7 when I insert / remove headphones and
when powering on and off?
The X7’s headphone output goes through a relay to the headphone output. The relay disengages briefly when the
X7 is turning on and off and when headphones are connected / disconnected from the X7, thus isolating headphones
from potentially dangerous transient pops when the amplifier section is powered on and off. The relay is a
mechanical connection that makes a small clicking sound when engaging / disengaging. Please don’t worry as this
is normal.
