Quad Cortex Bug Reports

Good morning everyone - new member here

A problem on my quad cortex yesterday

Heaphones out only left channel very annoing hum like white or pink noise, and sounds only right channel correctly

the other out jacks works well…and heaphones (Sony mdr 7506) works well on other devices

Tryed to reboot, changed jack cables and other headphones, even second power supply but still nothing

So just brand new product from three months…always used in good way

So how to solve this problem? Can fix by myself or need to call customer service for warranty?

Thanks a lot everybody

definitely get a message in to Support@Neuraldsp.com ASAP. Where did you buy your unit? Might also have to go thru the retail seller/dealer if there is one.
Support will most likely request a video and audio recording of the issue

Haven’t heard of that particular problem, not aware of a self-fix- sorry.

Hi
Yes already emailed neural support and asked video for better explain of problem, but i think tomorrow call thomann customer service for shipping back product and wait for repair

So anybody have my same problem before?

Hi friend, I encountered this issue too when I first got Quad Cortex. This could be solved by reducing the headphone out level in the I/O setting page, then the static hiss or white noise sound will go away. I guess this is because if we don’t turn down headphone output level (remember neuraldsp said headphone out is dedicated for high-impedance headphones), it’s kinda like we turning the volume knob all the way up in a headphone amp, in which we also get this kind of noise.

I hope this helps : ).

Good Morning

This white noise headphones out problem had with high impedance and low impedance headphones, usually use my Sony Mdr 7506 and white noise still have with sony like Mdr-EX15LP (tried different adapters but nothing)

same problem with both headphones

Tried to set output level lower than before and any kind of volume/impedance settings in the I/O setting page but still nothing

this is the reason that i asked for Rma

So if the problem can be solved in this way that you explained to me will be great, most important thing is when package return to me without any kind of problems because had to play live and i don’t want to have problems on stage during performance

Maybe change product with anoter one can be a little solution

Wainting for updates thank you so much 4 support
