They make excellent pro-quality headsets, and mics, for that matter, such as the legendary MD 421. I can't say about their prosumer or consumer gear, since if I'm going to buy Sennheiser I'm going to, you know, 'buy Sennheiser.' But the HME 26 and HMDC 26 headsets are top-rated, and cost accordingly (with tax, about $500). I know of many radio stations who use Sennheiser headsets in heavy RFI environments (a 50KW AM with the studio co-located with the transmitter qualifies as 'heavy RFI') with no issue. These are of course balanced output mics. The HME is a condenser (with pro-level 48VDC phantom power), and the HMDC is a dynamic. See http://en-us.sennheiser.com/global-downloads/file/739/HMx_26_Broadcast_0109_US.pdf for the manual. Several companies over the years have built excellent headsets around the Shure SM10 and variants, but, like with the HMDC 26 above and any other small-diaphragm dynamic you need top-end high-gain preamps to effectively use them (signal level is directly proportional to diaphragm size). I have an SM10, and the preamp is critical for low-noise performance of that mic. You could probably get a used or NoS SM10 for $150 or so without any issue, but the preamp will cost at least that much to bring it up to a signal level your laptop can use. For day-to-day use I use an older GE headset with a reasonable electret condenser mic that can be powered by consumer-grade phantom sources like a typical laptop mic input or devices like my Edirol R-09. I used to directly record on my laptop, but I found that using the R-09 and its pro-grade 24-bit converters, then doing production on my CentOS laptop, using Harrison Mixbus, gave me far better quality than using my so-so laptop mic input and sound card. Hum can come from many sources, but most PC motherboard sound cards aren't known for the quality of their preamps, and it would not surprise me if the preamps themselves are the source of the hum. Since you're using a desktop, you have some really nice options for audio interfaces; certain older MAudio Delta cards come very highly recommended; I have one of the Delta 1010LT cards that actually still works with Linux, and it has superb quality. A source for more info on high quality audio interfaces can be found in multiple places, but I'd actually recommend you search the archives of the Rivendell broadcast station automation package mailing lists for recommendations; see http://www.rivendellaudio.org/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As most desktops have the AC ground pin wired to the chassis, floating the chassis might well eliminate the hum. no need. as he said but the third prong is ungrounded. also, things like fluorescent lamps can greatly contribute to hum, although that often sounds like a buzz. lamp dimmers too, try switching any dimmers in the general area to either 100% on or totally off. correct. normally, repeat, normally, wiring for outlets and light are different wire runs, but they may be common leg of 240 mains at panel. not really, the wire itself has to be shielded coaxial wire. if its actually the headset itself, I'd suggest getting another one. I've had better luck with USB headsets of late instead of analog ones plugged into on-board audio, as the onboard audio microphone inputs are generally of very poor quality. even with usb headsets, quality/cost is to be considered. cheap preforms as cheap is. low the price, lower the quality of results. you get what you pay for. -- peace out.

Is it a 60 cycle hum? If so, it's probably induced by poor grounding. I suspect so. Is that something I can fix? that depends on where the grounding problem is... I dont' remember if this is a desktop/deskside machine, or a laptop... if it's a laptop, and if the power cord is a polarized 3-prong plug, I don't think there's much to be done about it UNLESS the outlet you're using is wired wrong, or there's a more widespread grounding/wiring issue in your building. if it's a desktop, I'll assume it's already a 3-prong polarized plug (unless someone has used a 2-3 prong adaptor, or the building is mis-wired. All the above kind of assumes a US-like outlet. I don't recall where the OP resides/works, so that may be all wrong. You can get cheap devices that plug into a 3-prong outlet and have little LED lights that indicate whether the wiring is correct, as regards ground and neutral, or not. Also, it's possible that you've got a cheap headset/mic combo that does not have the shielded audio cable wired correctly. It's also possible that it's a cheap-a** rig that doesn't even use shielded cable from the plug to the mic/phones. I've got one such headset here that injects hum into the microphone feed on either my desktop or my netbook. however, when using the netbook, if I disconnect the AC power, the hum goes away. Go figure. Reversing the (2-prong) plug in the outlet doesn't make any difference in this case. So, if I need to record something, I'll borrow my wife's USB headset which, as of last usage, worked fine. -- Fred Smith -- fre...@fcshome.stoneham.ma.us - But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. --- Romans 5:8 (niv) -- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
