Vega and Lectronics make some nice gadgets for IFB, but they are all mono. You might also look at some of the in-ear monitor systems. Stereo, but generally poorer sound quality than the IFB stuff. There are also some systems that are intended for assisted listening applications. In the US they are either infrared or they use the 72 MC band. These tend to have much greater range, but they have the poorest sound quality of the three. 300 meters is pushing it on all of these but you might be able to do it under the right conditions. --scott -- "C'est un Nagra.

Several firms make low-power ( 1W) stereo FM transmitters. (They're primarily
intended for transmitting to radios within your house, or on your own property.) With the right antenna, you should be able to get 300m (1000'), even if such distances are illegal. http://members.tripod.com/~transmitters/links.htm http://www.hobbytron.com/profmsub.html http://www.nrgkits.com/NRG-FM-Transmitters.html http://www.broadcastwarehouse.com/se...fm-transmitter |

"Vedran" can somebody please recommend me stereo wirelles headphones with range up to 300m? price is not important ** Is that 300m through solid rock, a forest full of conifers, from one submarine to another, from one subway station the next ???? Or it is open range across water or desert ? Or something in between like a crowded auditorium ............. Phil |

Yeah, but the OP asked about 300M broadcasting, so regardless, it's against
the law in America. -- Roger W. Norman SirMusic Studio "Scott Dorsey" wrote in message ... William Sommerwerck wrote: Several firms make low-power ( 1W) stereo FM transmitters.

I think in America, the 300M band is used for navigation beacons. --scott Seriously, though, I think you can easily do 300m distance, but you're going to need a licensed system, like the Lectrosonic stuff. The reason we have licensing is so that people don't step on one another, and working on a licensed band also keeps other people from stepping on you inadvertently. -- "C'est un Nagra.

The Lectrosonic wireless mics can reach that(1000 feet) line of sight If you are under very good conditions and are careful, you can often do that. I wouldn't want to count on it on a regular basis, though. no license needed Yes, a license is needed to operate ANY of the Lectro wireless mikes. In the US, anyway. You _must_ fill out the form and send your check in to the FCC. Do not operate these things without getting the license. I don't know of a headset that would do that though The Lectro IFB boxes have comparable electronics to the wireless mikes. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I asked Karl Winkler about this at AES he told me No license was needed and he would promise 600 feet under the worst condition with 1000 feet being the assumed nominal range George |

Here's what I know about the license issue: for VHF devices under 50mW and UHF devices under 250mW, they are classified by the FCC as something like "auxilliary TV transmitters". For applications involved with TV production, they should be licensed. For anything NOT involving TV production (i.e. stage, touring, etc.) they are ILLEGAL. This is the case for anything using the broadcast auxillary services channels. Which I strongly recommend using if you can, because they are hardly ever used. Doesn't matter who makes them: Shure, Lectrosonics, Sennheiser, etc. However, the FCC basically looks the other way because there is NO WAY they could actually regulate their use. There are millions of systems out there, and thousands more each day. This is not the case for the "wireless mike" channels, which are legal for anyone to use if they have filled out the paperwork. Or at least, that is the way it used to be. So basically, don't worry about it, unless you feel like making a donation to the FCC. This is of course not the "officially sanctioned response reviewed by lawyers" but instead the practical, real world one. Bill McFadden's Wireless FAQ is he http://groups.google.com/groups?q=%2...k.com&rn um=1 It used to be posted periodically to this group but it's been a long time since I have seen it and it may not have been updated in a while. I'm still trying to get a straight answer on the legality of using the low-band VHF wireless systems. I have a license form for one, dated 1976. Nobody knows if the itinerant use channels are still legal for wireless down there, at least nobody that I talked to. And, all the information I have may be totally wrong, since the FCC is currently a disorganized mess and regulations seem to be in constant flux. --scott -- "C'est un Nagra.

Well, Michael has to stay on his toes, standing by the phone waiting for the big guys to call and let him know who needs what. No time for technical details when yo' daddy's on the line. -- ha |
