Connecting To Other Audio Devices - Fiio X3 Complete User's Manual

5. Unpredictable ordering of files, such as placing several .ape and .cue files in the same directory.
The following directory structure is recommended: create separate folders for albums by the same
artist, and open subfolders within each artist folder to hold single albums in separate subfolders.
6. A mixture of music files of several different codecs and sample rates may also slow down the
player. It is recommended to place files of different codecs and sample rates into separate folders
and to play files of the same type in sequence from these folders, to prevent the X3 from having to
switch between different decoders frequently.
Q: Why does the X3 get a bit hot in operation?
A:The X3 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 X3 to heat up slightly in operation; but this does
not endanger the X3 or the listener in any way.

6. Connecting to other audio devices

Q: How do you connect the X3's line output (LO) to other audio devices?
A: The X3's LO is a standard line out that is designed to be connected to external headphone
amplifiers, car audio systems, home theater systems, powered speakers, etc. The LO provides
sound at a very high volume when either set to a fixed-level output or at the higher levels of the
adjustable output option, which can damage your hearing if you listen to headphones in this output
mode. Please set the output mode to Headphone output before listening to headphones with the
X3.
Q: How to utilize the X3's coaxial digital output?
A: 1. Set the X3's Select ouput to "Coax out" mode.
2. Use the provided 3.5mm coaxial adapter cable to obtain a standard RCA coaxial output port and
connect to the coaxial input of your S/PDIF coaxial digital-compatible receiving device using a
standard coaxial RCA cable.
Q: Could X3 be used with FiiO's docking station?
A: X3 could be used with FiiO's docking station DK1 and desktop amplifier K5 via Micro USB
connection.
