stopping "pop" in new set up?
Didn't want to start a new thread, but those following know of my recent
acquisitions and definite upgrades from mixing in the car. In a nutshell, a world of difference! Ok, here's an annoyance I'm having but not sure how to solve: The Presonus speakers and Behringer 202 box are connected both to one another with the box plugged in to the laptop USB port. Booting up the laptop, I seem to get an annoying "pop" from the speakers. Doesn't seem to matter if I have the volume on the Behringer turned all the way down, I still get the pop. What's the best way to circumvent this? I feel this could be *potentially* damaging to the speakers under the wrong conditions or over time. Thanks again! |

Turn the speakers on after the computer is finished making all of its rude noises. I have a sequenced power strip that has a few outlets that come on as soon as I switch the power on, a few that come on about 10 seconds later, and the ones that the power amplifier for the monitors are plugged in comes on 30 seconds later. I got mine at a hamfest for about $5, but they're pretty expensive normally. You're better off just getting a cheap switched power strip, plug the speakers into that, and turn them off before you shut down the computer, and then, when you boot up the computer and start playing some audio and don't hear anything, you'll remember to switch on the speakers. -- For a good time, call http://mikeriversaudio.wordpress.com |

Thanks, the six outlet power strip is exactly what I did. I had a spare for ages in the trunk of my car and now it has a use. At least I can now switch on the speakers simultaneously from my chair as opposed to having to flip the switch on the back of each one each time. And now avoid the pops altogether. |

Any system. geoff |

Turn-on pops are annoying, but they're rarely damaging unless something is really wrong or you've done something really careless. Still, it's not difficult to avoid them by establishing a good habit, so it's a good idea to do so. -- For a good time, call http://mikeriversaudio.wordpress.com |

Good thing they're not because I have forgotten to turn the strip off first a couple of times when powering down the laptop and got the pops. . I can see what you mean about the timed strips, but I'm under the impression the delay feature only worked during power up. However, I can see where such a delay strip would be useful. |

I've been turning on and plugging/unplugging stuff for 50 years and have never blown anything.

"JBI" :

Every single time your ears hear that loud unpleasant "POP!" will remind you to not forget the "correct" order next time. ;-) Just do it often enough and you will learn... |

Some power sequencers offer sequenced turn-off as well as turn-on, so you can have your speakers turn off first. But as I mentioned, and you've observed, it's an expensive way to avoid remembering to do things in an orderly manner. On the other hand, why ever turn your computer off? I have six or seven computers here and the only one that's ever turned off, other than for maintenance, is the laptop that's only used for travel. Also, I don't know if your speakers offer it, but several powered speakers off an automatic standby mode that puts them in a very low power consumption mode if they haven't seen a signal in an hour or so and turn on automatically when they see a signal. So that might mean that they might not turn on fast enough to catch the "pop" when you turn your computer on or off. -- For a good time, call http://mikeriversaudio.wordpress.com |

I have six or seven computers here and the only one that's ever turned off, other than for maintenance, is the laptop that's only used for travel. I turn them off because I only use laptops for my main system. I still have a desktop, but it's old and I have had instability issues with it lately that I am trying to work out. So, as a result, I have two identical laptops, one I seriously beefed up a year ago, while the other, this one, used for Internet and other less demanding purposes. I do video work as well, so needed something fairly robust. Now these laptops still probably can't hold a candle to what I could go out and buy today, but they are still better than the very old desktop. That being said, in the days when my desktop was the main workhorse, it stayed on for years. I learned some hard lessons though using it for the first part of those years without any kind of UPS and power outages destroyed a hard drive or two. Lesson learned and UPS introduced. Also, I don't know if your speakers offer it, but several powered speakers off an automatic standby mode that puts them in a very low power consumption mode if they haven't seen a signal in an hour or so and turn on automatically when they see a signal. So that might mean that they might not turn on fast enough to catch the "pop" when you turn your computer on or off. No, these Eris E5's don't seem to have that. Thanks! |

Trouble is, the delay can be just long enough to be annoying. Do class D amps have to warm up or something? |

Do class D amps have to warm up or something? No, not to "warm up" like tubes, but it does take a second or so for all the capacitors to charge and they don't all charge at the same rate. There may be some low frequency instability that appears as a thump in the output during that period while things stabilize. If you're talking about the automatic standby feature, yeah, you can miss a note or three before it decides that it's time to let the music through. That could be annoying, so if it is, don't use auto-standby, and turn your speakers on after you turn on whatever is feeding audio to them, and before you start playing the music. -- For a good time, call http://mikeriversaudio.wordpress.com |

Many amps, especially Class D amps, have a microprocessor on board that stages powerup. -- Les Cargill |

In article , says...
Many amps, especially Class D amps, have a microprocessor on board that stages powerup. I'd believe that. These monitors are quite recent. The delay is far more than a second or two - more like 15...just enough to be almost-annoying. They don't start until I send some audio and the delay begins then, not 15s after turning them on. --- This email has been checked for viruses by AVG. http://www.avg.com |

One on my computer rack, one on my console, and one one on my effects rack. I power up the computer first, the console (well, the C|24- I sold my analog D&R Cinemix a few years back), and one on my outboard rack which also controls my monitors. I reverse the order when I power down. I had to use trial and error to figure out what to plug where, but I finally have everything set so there are no pops. I really like having just three switches control the dozens of AC powered devices. |
