修改于 星期四, 六月 12 在 11:44 AM

[Inputs supported by K17]

K17 supports USB input, coaxial input, optical input, line input, balanced input, Bluetooth input, streaming, local playback, a total of 8 input modes. You can use the remote control or the front panel menu knob to remotely switch the input mode.

 

[Input Priority]

USB input: Front panel USB input port > Rear panel USB input port

Other input modes can be switched by knob control menu selection, infrared remote control or FiiO Control APP.

Airplay and ROON: The now operating mode will have priority. For example, if you connect ROON to play songs first, and then your phone is connected to airplay. The K17 will switch to airplay mode.

 

[Output supported by K17]

K17 supports 6.35mm single-ended output, 4.4 balanced output, XLR4 balanced output, RCA line output (LINE OUT), balanced line output (BALANCED OUT), optical output, coaxial output, a total of seven output modes.

Note: Optical and coaxial ports have no output in line or balanced input modes

 

[Output Priority]

[PO] front panel output:4.4mm, 6.35mm and XLR4 balanced output, with the same priority, can be output at the same time. But it is not recommended to use it for a long time at the same time, especially when the impedance of the two earphones is quite different. The output volume may be too loud and can cause the low-impedance headphones in it to overload and cause damage.

[LO] or [PRE] rear panel output:LINEOUT and BALANCE OUT can be output at the same time.

[PO+PRE] the output ports in the front and rear panels have output at the same time; the volume is adjustable.

[Coaxial and Optical outputs]

Coaxial and optical output with no control switch are always in the output state. The volume of optical/coaxial output is not adjustable. You can adjust the volume of the decoder device connected to the out port. (Optical and coaxial ports have no output in line or balanced input modes)

 

[Are there any differences between the 2 sets of RCA_LO outputs on the rear panel?]

There's no difference. It's completely wired in parallel and can be used to access a pair of main speakers, a subwoofer.

 

[Which headphone port on the front panel has the best sound quality?]

Theoretically, the XLR4 balanced port is not much different from the 4.4 balanced port. And the balanced output port sounds more balanced and has more power than the 6.35mm port.

Different headphone ports with different headphones will have a different taste. The sound quality is not good or bad absolute distinction. It is recommended to try and compare by yourself.

 

[The relevant recommendations for connecting speaker]

1.Generally, when connecting to the amplifier or active speakers, please adjust the volume of the amplifier or active speakers to low level before connecting. Gradually adjust to suitable level after connecting to avoid popping sound.

2. In LO mode, the output volume is max and can not be adjusted . please adjust the volume of the amplifier or active speakers to low level before connecting. Gradually adjust to suitable level after connecting to avoid popping sound.

3. When connecting to speakers with no volume adjustment, it is recommended to use PRE mode in K17.
