  1. I've been following the 633 threads but haven't come across any comments about whether it throws any radio interference into your wirelesses. I would think not, since it doesn't have a hard drive, but I thought I'd ask... Any Comments? Cheers, Brent Calkin
  2. Hey guys,I am in the market for some wireless handheld microphones for AV hire use. Mostly corporate gigs at smaller venues and no more than (4) mics at a time. I've been doing some research and see a lot of negative comments from the pro community regarding Shure BLX. I don't know much about RF and was wondering if any of you all could help me understand if/why they are a poor option.Thanks!
  3. Had a shoot in a building that may or may not have had an FM radio station broadcasting from it in the Mid-Wilshire district of Los Angeles. Multiple frequency scans with my Wisycom MCR42S receivers with the latest firmware produced many clear frequencies with very low noise floors. Upon dialing up the transmitters (MTP40S with latest firmware), the gain level on the transmitter showed that the lav mic cable was acting like an antenna and picking up all kinds of stray RF. Here's a photo of the transmitter gain level in a silent room with a DPA 4061. Tried a B3 and COS-11 and got the same resul
  4. Hey Everyone, just wanted to let you know that I successfully combined a Zaxcom and WisyCom Sytem together in one Antennatree. I used the Antenna output of the PSC SixPack to feed the MicPlexer2 and from there on went to 2 digital Dual Channel Zaxcom Recievers and one WisyCom analog Dual Channel Reciever. I wasn´t shure if that System would work or if I would get in trouble especially with the WisyCom Reciever beeing fed by the MicPlexer2. But so far everything seems to work fine without any RF loss. cheerz Urs
  5. Hi folks! I'm a bit of a hardcore lurker here, and while I read much, I post little. I'd first like to commend everyone for maintaining such a fantastic community and resource for soundies everywhere! I've learnt (and continue to learn) so much from here. One thing that someone said (can't remember who) but it really stuck with me, was that in this day and age a good production mixer needs to be as knowledgable as possible about RF, and so I've been researching as much as possible and trying to come up with ways to improve my professional practice. One day soon I'll own a full Zaxcom
  6. Hi does anyone know any RF headphones which can cut it for critical listening, or are they all too compressed to use? I was looking at the Sennheiser RS165, which are closed back. I wanted something for artists to use tracking vocals in a studio, so they need to be zero latency, but also to use for general mixing. Are there any RF or equivalent wireless headphones anyone knows of that are decent enough quality?
  7. Hi guys, Anyone know which blocks are clean in Georgia, Tbilisi? Best regards, Nir
  8. I'm doing a reality show at the moment and am sometimes getting this strange interference on wireless. The wireless in question is a Sennheiser 2000 series with a DPA d:screet 4060 mic going into a Nomad. Like you can hear from the sample, it is a quiet pulse not too far from a digital "phone ring" sound. Now I want to ask if anyone might recognize what it is? I'm guessing it might be 4G or 3G phone interference or some other type of interference from a smartphone bleeding into the signal? If it is, then I suppose I'm S.O.L. since the talents of the show are on their phones all the time. Lucki
  9. This Wednesday July 30th! Join us at our Los Angeles branch as we host Massimo Polo for a special Wisycom Q&A session. Massimo will be discussing some future firmware updates, getting the most of your system, and best practices for wireless on set. The event starts at 10 am PDT. You can RSVP by emailing rsvp@trewaudio.com
  10. Hey guys I'm about to do a short shoot in Japan and was wondering if anyone out there has shot there and what lectro blocks are clear? I know Japan has a 10 mW power output limit but was hoping to still use my normal mics as its a short shoot and don't want the hassle of renting locally. Right now I am planning on using blocks 19 & 21 for my cast. Any thoughts on this? Also, anyone use comteks out there? Thanks a bunch -Danny McCullough, CAS
  11. so I was requested by Rado to do a test of frequency scans on block 21 with my Nomad on and off, I did the same with block 24. Bloc 24 with Nomad powered off Block 24 with Nomad powered up Block 21 with Nomad powered off Block 21 with Nomad powered on nothing special done with this test. bag was sitting on my kitchen counter, Nomad switch off, turned on BDS and powered up receivers and did a scan. Then turned on Nomad and re-scanned. Looks to be some RF in block 21 after the power up. Not sure if Glenn has anything scientific for this. My SRa's are fairly close to t
  12. a palm-sized scanner. the spectrum analyzer is a handy and affordable palm-sized box that scans a range of frequencies and tells you what’s nearby. http://livedesignonline.com/sound/closer-look-rf-explorer-scanning-wireless-world?NL=LIVE-03&Issue=LIVE-03_20130523_LIVE-03_716&YM_RID=peterlopata@yahoo.com&sfvc4enews=42
  13. Hi all, Pretty new to field sound. Ive recently been having issues with scanning for clear freq's. i have 4 lectrosonic 411a's. maybe im doing it wrong? my way: Turn on all receivers and transmitters. let sit for a couple seconds. then, turn off all transmitters. Scan with all 4 receivers ( blocks 19,20,(2)21's ) at the same time. find the clearest location on each rx and tweak on all matching tx's. everything is fine until i place them on the talent. It seems like i cant be any more than 10 feet away from all 4 without losing full signal. any suggestions would be great. thanks
  14. Hey Guys, Thought I would share this crazy story. I was shooting a reality show for Much Music in Banff, Alberta and the director approached me the morning of with a crazy request (as per usual). He wanted to have the contestants start at the top of this hill and go tubing down to the bottom delivering lines. I thought it would be a great chance to try out my Lectro SMVs at 250mw. The talent was about 150 meters away at the top of the hill and I had to pull my 411s out of the bag to get the antennas higher up but as you can see from the picture, pretty much full RF the whole way down.
  15. I've been reading A LOT of stuff on the forums lately about antenna's and RF. I'm looking to buy something for my bag to increase the range of at least one mic - not sure if I want to install a distribution system to feed all 5 of my receivers. I read up on the antenna tests that were in the 695 magazine a couple years back, where they seemed to find that mixing antenna types for lectrosonics gear was not a good idea, because lectro's add the signal from the antennas together, instead of picking one or the other. I want the range that a batwing antenna would give me but I'd prefer to carry
  16. My friends and former neighbors at Vark Audio have developed some easy-to-travel yogi antennas specifically for us location folks. They look pretty good and Evan Mater, who designed and built them says they seem to perform pretty well, offering around 10 dB of gain. Here are a couple of cellphone shots I snapped of the prototype while I was visiting the Vark shop today: The longer section is right around a foot long, just for reference. Mounting is via 3/8" X 16 threads in the Delrin block, which you can sort of see in the picture. Evan says the mounting holes will be on the other side of tha
  17. Hi all, I have an older Sanken CS3e and I am picking up a lot of RF interference when it it held next to electrical appliances particularly florescent tube lights. There seems to be little to none Interference when the rear of the mic is pointing at a light but if the mic is parallel or pointing at the light then there is a considerable (completely unusable) amount of interference. We were using it along side a newer CS3e which didn't suffer from this problem, which leads me to believe that there is a problem with mine. I am aware that there is a modification for older CS3e, which I did, bu
