Problem with ddj rr with dm 40

Wait, you don't have sound or it's quiet?

Have you properly installed the drivers and configured the DDJ-RR as your audio device within the rekordbox preferences?

Have you also adjusted the channel trim and master level knobs?

It was ok for 4 hours. After did not worked.

After a break it work for few seconds and again the volume goes to very very low level.

Can you confirm if the speakers continue to work after that same duration, or if you use a different set of speakers / output device, that they still receive signal? I'm trying to determine if it's the speakers or controller causing the issue.

I put the speaker on my pc and have the same issue.

Okay, so that helps narrow it down.

Are you using the speakers at what might be considered a high volume? I'm wondering if the amplifier circuit is overheating and engaging thermal limiting?

Let's around say around 75%volume. This is the reason for i writting here, i dont no. I dont like the ideea of beeing limiteded. What is the best solution off speaker for ddj rr without eny limitation? And how solve my problem?

Unfortunately it's impossible to tell if, even at that volume level, it's simply overheating, because a low input signal at 75% volume may still be low output, but a high input signal could be much louder, and thus driving the amplifier in those speakers to overheat.

It's always important to match the speakers / amplifiers (whether separate or built-in) to the usage. Obviously a stadium-sized concert will need much more power and output than a nightclub, which is still far more than a house party, or even a single room. If you're overdriving the DM-40's to the point of overheating and thermal shutdown engaging to protect the amplifier from failure, perhaps you would be best suited with a larger speaker with a higher output capacity.

We have several models, but again - these are more for studio. If you're looking to rock a party, then these would be better suited for that purpose.
