8. DSP Equalizer Introduction

All working modes of the K19 support DSP equalizer, which can be adjusted through the connected computer or mobile phone.

When using the DSP equalizer on a computer, please use a USB cable to connect tthe K19 through its RS232 port to the computer, and download the DSP equalizer software first.

(Windows version download: Click here MAC version: Click here You could also search and download 'FiiO DSP' from the APP store. ). When using the DSP equalizer on a mobile phone, please download the FIIO Control app to use it.

When K19 switches EQ on and off, the sound is interrupted for about 1 second?

K19's EQ is a hardware implementation. When switch on or off the EQ, the system will initialize, turn off the power and switch the audio path for the DSP chip.In order to avoid the sound like the impact sound which affects the experience, so the mute treatment has been done. The EQ of the player is realized by software algorithm with no hardware involved, so there will be no sound interruption when switching.

Can the EQ parameter files exported by Windows DSP and MAC OS DSP be shared?

Yes, the EQ parameter file exported from both systems can be cross recognized and used. You can also share it with other users.

DSP EQ is available in which output?

All working modes of the K19 support DSP equalizer for analog outputs, such as PO, BAL, RCA_LO, BAL_LO.

The DSP EQ is not available for digital outputs, such as COAX and OPT outputs .

Since the EQ function of K19 is realized by the dedicated DSP chip, the EQ is not available for digital output signals (coaxial/optical output) which do not pass through the DSP chip is not available.
