Hi. For a series of grounds, I insert my headphone in the headphone amp which is connected via rca with the Topping dx3 pro dac. I would test a file and I plugged the headphone directly in the dac. It did not work. I used foobar2000, then I tested another player but with the same result. I am not able to listen without using the amp. The dac is a its best: 0.0 db. Why?

Thanks and best,

davide

It's in the manual.

It's probably set to 'line out output'. You need to enter the setup menu and change it to one of the other two output modes.

Thanks. I'll check it. Nevertheless, I didn't set the dac to "line out output". I read the manual, but it is very cryptic...

Thanks,

Per Topping/ Amazon

  • Pre-amplifier function :Adapt to different usage scenarios, DX3 Pro+ has 4 output modes: Headphone Amp, Headphone Amp+ Line out, DAC, and Pre amplifier.
The manual is a mess for sure. But somewhere on the remote there is a headphone out buttton and light on the main display if set to on. Likewise there is a line out button on the remote and a light on the display.
