Hello, having acquired the Quad Cortex today, it is impossible to get any sound, whether on a speaker or headphones. Does anyone know a solution to this problem, or am I missing something? I followed all the steps in the start-up guide. ---

It could be multiple variables. Start with the I/O screen, depending on which input you are using ensure you are seeing signal incoming. If using XLR or 3/4 out, ensure your gain is up for volume. Also make sure your volume knob is all the way up as recommended by NDSP etc. ---

Thanks for you response see signal in the input and Multi Input, as well as in I/O, but nothing is coming out. I’ve tried with a Kemper Kabinet speaker and with headphones, but nothing works Even though I turn the gain up to the maximum, set the volume to the maximum, or try different combinations, nothing works. ---

I would look at your signal chain next, try setting your output on row 1 to multi-out and see if that works. Also when using headphones there is a separate volume for that as well within the I/O pull down menu. ---

Unfortunately, I have set the output to multi-out, but it still doesn’t work. The same goes for headphones; no matter how I adjust it, it doesn’t make a difference. Can you send links to images of my setup if I’m correct? ---

I notice your input 1 noise-gate is enabled, try disabling the gate and or make sure you aren’t cutting too much signal out. ---

I set it to 0 and disabled it, but it still doesn’t work. ---

What about your pedal in the chain? And… Disable (“Bypass”) the blocks you don’t want to be active. Do NOT use “Mute”. ---

> [@holba](#): > > What about your pedal in the chain? > > Attach a Guitar and Volume up 🙂 I have tried activating all the pedals and turning the volume up to the maximum, both on the guitar and the volume knob on the Quad Cortex, but nothing works. I have even changed all the cables and reconnected my guitar to my tube amplifier, and it works fine except on the Quad Cortex. ---

where did you buy it? You should contact them, and [Support@NeuralDSP.com](mailto:Support@NeuralDSP.com) it could be a hardware failure. Have you tried restoring or resetting? ---

Are you using “Mute” instead of “Bypass” to switch block in your signal chain off? According to your fotos seem’s like not. ---

Have you tried creating a simple preset and testing that? Otherwise, I would reach out to [support@neuraldsp.com](mailto:support@neuraldsp.com) so they can grab diagnostic logs and try to resolve the issue for you. Last thing to verify, are you using the OEM power supply? ---
