Do digital signals (CDJs/Serato) output a special signal that can damage speakers? (pg. 2)

What I would suggest is, once everything is working again. Set up the gear like normal, and run program (music) through the rig. I'm not familiar with djm-2000 but I'm guessing 10 on all faders is most likely 0db. Set a good level input and output. Let the levels go to 0db. Once that's found, connect to your amp without speakers attached, don't want to piss off the neighbors. Crank both amp channels to full and watch what your amp is reading. If you're seeing limits come on, try adjusting the gain on the back of the mixer like Clay described and see if that eliminates the limits. At this point your entire system should be unity or 0db. As far as turning the amps, I wouldn't go any lower than 2 o'clock. What model amp is it and what type of speakers? Are the speakers running passive full range, or bi amp? The reason is because all our boxes at Clair are JBL loaded and we use Crown, QSC, and Lab Gruppen amps. I cam give you info on what these guys want to see.
Another thing. You friend may want to consider at some point, getting a compressor/limiter. This will greatly protect the speakers and the amps.
This is bugging now, who is sound guy that told you Serato was the problem? Maybe he's hitting too much of the old stale 54 candy cause that's a crock a . |

| I once thought the same thing. When I first made the transition from vinyl to digital music. It hurt my ears. I had never experienced that before. I would listen to my mixes that I had recorded via my turntables in the same headphones and my ears didn't hurt. But whenever I'd spin music I got off of beatport they would. That led me to believe that because of better frequency range, and the fact that I hadn't gotten used to it, my ears hurt. Maybe that frequency can blow speakers too. |

| What are you talking about Ryan? If it's hurting your ears, turn it down. |

You hadn't listened to a CD before?
Or do you mean when you started using MP3s? If they were poor quality MP3s then the digital distortion may have been what was hurting your ears. |

On the original topic...
While I'm convinced this guy is talking out of his arse, theoretically you COULD end up with some unwanted high frequencies in the output signal.
This is how:
Although the digital signal only stores frequencies of up to 22kHz (or 48kHz in a system with a sample rate of 96kHz - the maximum frequency is always half the sample rate), the data is just passed around as 'numbers' until it's actually needed as an analogue signal. This happens at the output of the last digital component - in this case the DJM2000.
If the last digital-to-analogue converter (which will be on the output of the DJM2000) is a big crock of e, it could suffer from clock noise... the clock in these things can be several hundred MHz, so that frequency can get dropped onto your signal line.
But even the cheapest systems should have a low-pass filter on the output of the digital circuitry to get rid of anything out of the range of human hearing - that includes Pioneer mixers, even if their sound quality is fairly rubbish at the best of times. |

| I wonder how much longer it will be until we see dj equipment with word clocks built in or atleast a connection to an external clock. Or possibly better D/A convertors. Both would help. |

S/PDIF uses a word clock... |

| I mean a word clock in which you can tie the mixer, cdj, computer, into one source (master clock) so everything clocks at one rate. It eliminates all the crap like noise, jitters, and data errors. Basically an Apogee Big Ben for dj gear. |

what was hurting you was your own beliefs, nothing else.
you are out of your mind, and not in touch with reality what so ever.
half your post are completely retarded the rest are just ing missinformation. easy down on the ecstasy bro. |

| audio signals were not made to destroy speakers, only if you set the volume to high, kinda obvious dont u think |
