Headphone Output Hiss

Hi

I just bought a JoMox Airbase and on testing it I’ve found that the Headphone Output has really bad hiss on it

Ive tested the main outputs and the individual outputs and they seem fine

As it’s a old unit should I be concerned that the hiss could be the start of things failing on the unit or is it something I shouldn’t worry about

Thanks

What kind of headphones are you testing this with?

Hi there m50x audio technica

Thanks

So 38 ohms it seems.
Have you tried other headphones?

I don’t know much about impedance impacts but I’ve noticed that using DT-770 250 ohms made my Push3 hiss disappear… Could be related.

Thanks I will try it out with another pair if I can find them
