Foreword
Thank you so much for purchasing FiiO's portable high resolution lossless music player M17.
We have prepared this complete user manual for you. We hope this manual can help you get
the hang of the M17 and unleash its full potential.
An introduction to FiiO M17
The smart desktop-class M17 is an entirely new chapter of FiiO digital audio players. Its
desktop-grade DAC, amplification, power supply, etc. give it the output power and sound
quality to rival and perhaps even surpass highly-regarded desktop systems – but in a
portable package.
The left and right audio channels each contain a desktop-class, 8-channel ES9038PRO
flagship DAC. This means that each audio channel has 8 parallel outputs summed together
for superior resolution and minimal distortion for extremely pure audio reproduction.
The desktop-class THX 788+ headphone amp has an output power of up to 3000mW per
channel with a lower output impedance – allowing it to more effortlessly power all kinds of
headphones.
Desktop-grade power supply and gain: the M17 contains two power supplies – a battery
power supply and a power supply powered by external DC power. Under battery power,
there are 4 gain levels: low, medium, high, and headphone mode. When under DC mode,
the enhanced over-ear headphone mode gain is unlocked which can go as high as 16dB in
balanced output.
Desktop-caliber internals: high-end TI OPA2211 op-amp, supercapacitor, ultra-low noise
LT3045 LDO, NDK femtosecond crystal oscillator, etc.
Desktop-level connectivity: not only supports commonly used 2.5mm/3.5mm/4.4mm
headphone outputs, but also adds6.35mm output, RCA coaxial port, USB3.0 and USB2.0
ports.
With desktop-grade configurations, the M17 will be your great partner on the road of music.

The priority of the M17 output port
1. When the PO 3.5mm, 6.35mm, 2.5mm and 4.4mm are output at the same time, the output
will be given priority in the order of insertion; if the 6.35 and 3.5 earphones are inserted at
the same time, both ports have output, and the status bar will display two icons (The same is
true for LO); 2.5 and 4.4 are the same as 6.35 and 3.5.
2. When both balanced and single-ended headphones are plugged in, the first plugged-in
headset will have a sound, and the status bar will only display the first plugged-in headset
icon.
3. The SPDIF output is controlled by a separate switch. The analog output (PO/LO) and
SPDIF digital output can be output at the same time.

4. According to the Android system's own processing method, Bluetooth transmission and
analog output (including SPDIF) will follow the principle of post-access priority.
