    Your calculations are absolutely correct for 50 Ohms. Fifty Ohm values are typically used for RF levels since that is the most common impedance for RF devices and RF measurements. For audio levels, 600 Ohm levels were once the most common. Pro equipment still uses those values as a reference. That is what I did when I referred to 2 dBm, thinking of meter levels in a pro audio mixer or recorder. However, the most correct value for the Lectro IFB output is the 1 Volt into 50 Ohms specification. That is exact and has nothing to do with RF but is an average impedance value for most headphones that typically range between 32 and 80 Ohms.

    All this to say, the IFB will have the least self noise going into a line level input that has enough gain to match to low line levels of 0.1 to 0.3 Volts RMS.

    Larry, can I ask why Lectro doesn't make IFBR1B with a switch to make it line-level and bypass the headphone jack? IFBR1b has to be the smallest transmitter on the market. I know a lot of cam ops would be happy about that. 

  2. So I made a Tip pin 2, Ring pin 3, sleeve pin 1 and one with out Ring pin 3(negative) and it sounded way better. less tubby, not sure why. I'd recommend opening one up and cutting off the connection at pin 3 connection. I know I've read this before. Just forget these things. I need to make my own note book when these things come up lol.

  3. Pertaining to corporate and doc work(haven't done film in a while): AS most of my clients don't know what cedar is, nor do they have post that are aware of the new software, I'm trying to figure out a standard of how to use the new technology. Currently I've set up a bus with processing called "processed audio", or I've added the plugin to the master buss two both channels. Any thoughts on what a "standard" could be? I understand if post made this request, but at the moment I've not yet had one. 

    Is there any reason other than client knowledge why we should be still recording a stereo master track? Say a two person on cam interview, With the 8 series we can make two mixes one lavs, the other booms, each with their individual compression, automix, and cedar. I'm not trying to put post people out of work, but many gigs I work on I know the client is editing in house. 

  4. Wondering if anyone knows how to disassemble an HM. I've got a short in the connector. Shorts when moved. Trying to fix today for quick turn around. I'm hoping this is a simple broken wire or connection as the manual states 

    "do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service."

  5. Thanks but I wanted to make it myself.

    I'm looking for wiring confidence confirmation as I don't have a way to test the cable except on set.

    In theory I think there shouldn't be any phase cancelation issue 😑. Sending same signal to two channels usually just gives a volume bump, but has phased each-other out in circumstances that escape me at the moment. I used to do installations with Bose "mono" L1 systems and sometimes a y cable would cancel out the center in a mix. 

  6. Hi I found the wiring for red 5pin xlr.

    I'm Wondering if I can wire the LR receiver Ta3 mono to a 5pin xlr out to both Red channels as client likes to playback most takes. Having both speakers playing on monitor would be more "professional" though I understand it would not give me that much more volume. I'm unclear of phases issues with this kind of wiring. 

    Thanks

  7. Looking to update my usual R11 or vampire clips for my cos11 and I see a lot of new tools out there. I don't see any youtube reviews and would be grateful on any write ups. 

     

    Thanks

  8. From wikapedia 

    "It is possible to recreate the three-dimensional soundfield, however the soundfield microphone particularly shows its versatility in a stereo or mono application. For example, a forward-facing cardioid is produced by2W+X{\sqrt  2}W+X. By combining the signals in various proportions, it is possible to derive any number of first-order microphones, pointing in any direction, before and after recording. For instance, provided the W, X, Y and Z signals are recorded separately, it is possible to pinpoint the microphone to a certain response from the audience even after recording. Examples of software that perform these calculations are Visual Virtual Microphone, SoundField's Surround Zoneand Ambisonic Studio's B2X decoders plug-ins.

    In other words, the B-format recording can be decoded to model any number of microphones pointing in arbitrary directions: each microphone's pattern can be selected to be omnidirectional, cardioid, hypercardioid, figure-of-eight, or anything in between. This can be done live or in post-production (after the recording is made)." 

    Considering one of the most popular mics (cs3e) has 3 capsules this seams like a viable option.

    Though tetra mic site talks about this decoding technique, Sennhiser dose not mention it on their site. 

     

  9. So I did a project for youtube with this mic as a sub-sub-sub... contractor. I really enjoyed working with it so just bought one. I've not done much MS recording and wonder if this would replace ms recording in the future or at least be another option if post can handle. I really like listening with these type of mics as I've also used the tetra mic. 

  10. Looking for an experienced boom op for most likely one day of filming in a house. Doc style filming in a living room of a birth. Must have good sense of frame line as camera will be moving. Date in between Dec 1-10 email sound with seth at gmail directly please. Working out if they can afford rate to block out dates for one person, or if we get a few names and see who is available when the labor starts.

  11. I know this production company.  This is work for hire for them, and they do not pick the music for their shows.. the network does.. look up the music supervisor of record for the program and contact them.

     

    BTW.. Crazylegs are reputable, and fine to work with.  Many Atlanta based sound mixers have worked for them

    Thanks for the info! 

  12. Very nice, Seth. It's not difficult to publish your work with BMI, then list it at the Library of Congress for copyright purposes. I did it years back when the sites were new and clunky. I'm sure it's much easier now.

    Thanks! and thanks. it's on the to do list. Did it for the first record. 

    Thanks Crew! Mckay was always saying "yay it sounds like people in a room" when we got to that point. And we talked about the "vibe" a lot  You guys must have learned the same terminology.
