11. How to use coaxial output on QX13?

To use the SPDIF (coaxial output) function, you need to enter the menu and set the SPDIF switch to ON. Then, use a dedicated 3.5mm-to-RCA coaxial cable to connect the QX13 to the input of another device for signal transmission. The pin definition diagram is shown below:

When using the 3.5mm audio output port for single-ended output, it is suggested to turn off the SPDIF switch to avoid conflicts.

Note: The coaxial output volume is fixed and cannot be adjusted on the QX13. Volume control must be handled through the connected DAC or power amplifier.
