SC LIVE 4 controls stopped working, followed by no Master Out or headphone Cue

Engine DJ Hardware Standalone Controllers

Hi everyone,

I am having several problems with my Denon DJ SC LIVE 4 and I am hoping someone has experienced something similar.

The issue initially started during a live set, when the main Browse/Select rotary knob stopped responding. I could no longer use it to browse through or select music, and the channel Load/Select controls used to load tracks onto the decks also stopped working.

Because this happened in the middle of the set, I reset/restarted the unit. After the reset, the control issue was no longer the main problem, but new audio problems appeared: there was no longer any audible output from the Master outputs or the headphone Cue, even though the channel and Main level meters continued to show an audio signal.

I connected it to my Mac, entered firmware recovery mode by holding the Browse knob, Back and Forward buttons while switching it on, and reinstalled the firmware using the SC LIVE 4 updater.

The unit now starts normally again. I can load and play tracks, and both the channel meters and Main meter show an audio signal.

However, I now have no audio from:

  • The Master outputs to my external speakers

  • The headphone output when pressing the channel Cue button

I have already checked:

  • Channel Gain and faders are open

  • Main Volume is turned up

  • Crossfader is centred

  • Cue button is illuminated

  • Headphone Level is turned up

  • Cue Mix is fully towards Cue

  • Speakers, headphones and cables work with other equipment

  • The Mac and USB cable have been disconnected

  • All USB drives and other devices have been removed

  • The unit has been fully powered off and unplugged

  • Master Out and headphone Cue have been tested separately

The meters clearly show that audio is playing, but nothing reaches the physical outputs.

Because the first symptoms were the Browse/Select knob and track-loading controls becoming unresponsive, I am wondering whether this could be a wider control-board, audio-board or internal hardware failure rather than just a firmware or routing issue.

Has anyone experienced this combination of problems? Are there any additional diagnostic or reset procedures I can try, or does the unit probably need to be repaired?

Thanks in advance.

Was it very hot where you were playing? Is your player mounted in a case?

If the player overheats, you can experience the kind of problems you’re describing.

If the player is in a case, take it out so it can get some ventilation.

If the player has overheated, you need to wait for it to cool down before starting it up again.
