  1. I see what you mean. I think of them all as rack mount panels but as you have pointed out only one is actually named a "Rack Mount". My apologies for jumping in and causing a distraction.
  2. Hi, You will probably need to specify the exact dashboard you are considering. The mounting hole pattern should match but most of the dashboards pack the receivers to closely for the extra radio output connector to fit in the layout. For example; the 644B-V2 may have just enough room to allow for the extra connector, but the 633B-V3 certainly will not.
  3. Hi, Can you please direct me to the little metal wire guard style mount you have mentioned? I would like to compare them to my home made attempts. Thank you.
  4. I found, and remember having seen, the Gotham Audio car plant video. The placements seem fairly routine. The results seem remarkable. I am very curious about the mic placement in the cafe scenes. Those shots remind me of how often I hear awful noises from hidden body mics while talent is squirming around between takes, but in this case the squirming around is on camera.
  5. Hi Jason, Thank you for the reply. I will look for the articles you mention. I am very interested in the mic placement ideas. Thank you.
  6. Hi, I am impressed with the sound. Does anyone have any first hand knowledge of how it is produced? The convertible scenes are uncanny. The amount of clean sound in the cafes seems impressive. The host often brings a noisy car to the episode, and usually wears slim cut shirts that seem to pull and tug as he relaxes in a seated position, yet the sound seems clean. Maybe even too clean. I am wondering if the show depends on good luck, extraordinary amounts of over shooting, or magical post production clean up to get the clean sound I hear. It seems like these epis
  7. Hi, I have some IFB R1A receivers without belt clips and would like to add them. The official part comes in a kit with a new side bezel plate and other goodies. Lectro also has a bunch of other clips intended for their transmitters, which look very similar, and these are offered without the extras so they are also cheaper. The Lectrosonics BCWIRE clip which Lectrosonics describes as suitable for UM200 and UM400 transmitters seem like the ideal form factor for my purposes. The Broadcast Shop describes this item as suitable for the IFBR1 which makes me optimistic.
  8. Hi Constantin, As a suggestion, rather than normalize the peaks to 0dBFS, it would have been possible to normalize the guide tone to a consistent level, and then use the exact same amount of amplitude required to line each of the guides on each respective sample of content. For example; if wave-1 was adjusted by +0.03dB to align the guide tone peak to -20dBFS then adjust the relative content +0.03dB. Likewise, if wave-2 was adjusted by -0.07dB to align the guide tone peak to -20dBFS then adjust the relative content -0.07dB. This procedure would account, somewhat, for
  9. While this may be true for the new fangled virtual reality presentations and perhaps some surround mixes, ambisonics has traditionally been employed to provide an opportunity, either while recording live or mixing in post, to isolate specific portions of the sound field from the whole, with greater precision and latitude of choice, than is possible with other traditional microphone array geometries, when used with similar near-far or distant placement. VR surround effects have come into vogue and currently receive attention, but the introduction of new microphones and advanced dsp
  10. This device looks fantastic, but I imagine it would be more readily received by aficionados if it was priced somewhere between $7,000 and $23,000. The combination of components in a compact integrated form factor seems like a recipe for over coming the many limiting factors in traditional setups. My first experiences with ambisonics was with a corporate owned CalRec system. I have been observing the evolution of technologies, and the elimination of real life problems with ambisonic production for quite a while. It does not seem hard to imagine that a mic array based on
  11. Hi Borjam, Thank you for explaining. This has been very helpful. Thank you.
  12. Hi Borjam, Thanks for the detailed reply. "Romex" wire is not any sort of fancy wire. It is construction grade wiring used in the building trade. Here in the USA, Romex is a trademark brand name that has become a generic name for a wire packaged to suit electrical distribution within building structures. The name is used sort of like Fridge, or Kleenex. It is a very cheap, and easy to source solid core wire that comes in small gauges such as 14AWG and 12AWG. I am only interested in building receiving antennas and I am not experimenting with transmission scenario
  13. Thanks for the additional info. My interest in making DIY 1/2 wave dipoles with the little PCBs I illustrated is related to the idea that it would be easy to connect antenna arms that are the relevant 1/4 wave length for some specific frequency within the 450MHz to 650MHz band. For example; I have been making some, minus the balun, out of "romex" solid core copper, and cutting them to length as needed. It is super easy to refresh the unit with a new length of romex in between projects. If the length is tuned (by choice of length) to resonate near the desire
  14. Looking at the pdf files produced by the MiniVNA testing it seems like the impedance varies widely over a spectrum of frequencies tested. Does that suggest that a dipole structure, as sized in length for some particular frequency, will have some arbitrary impedance at the intended frequency, while at other, perhaps nearby frequencies, the impedance can be significantly different? Can the impedance be accurately calculated, or is a VNA type test the only way to arrive at an accurate figure? It seems that when I read about antennas with an interest in reception, matters t
  15. Thanks for the suggestions. You are correct that some of the SMDs I have found are Mini-Circuits brand, and I agree that it is possible for a DIYer to hand solder a SMD to a PCB, but the process is not what I would call convenient. I have been reading about receiver antenna design for a few years, but have yet to get to the point where I understand how to calculate, measure, and or anticipate the impedance bridge ratio necessary to make proper use of a balun when connecting a home made receiving dipole to a 50 Ohm transmission line.
  16. I have looked around for baluns for DIY dipole projects sized for use within a range of 470 MHz to 600 MHz, but have never found anything that seemed suitable. It's been a while so my memory is fuzzy. It seemed that some very tiny surface mount items may have had specs that seemed appropriate, but were inconvenient to implement in a home brew project. I would appreciate learning how to utilize two coils of wire to make a suitable device, so that the balanced function of the dipole structure can be taken advantage of. I think it could be fun to commission some small inex
  17. Hi, I never had a reason to update the software on my 633, but next week we have a 6 input round table project that makes the Dugan Auto mix seem like a good option for the scratch mix. Has the latest 633 firmware been good to you? Thank you.
  18. Perhaps someone can patent an inline balancing transformer widget designed to adapt an unbalanced lavalier microphone to the balanced input of a transmitting recorder and sell the new fangled devices to operators who promise not to get caught mounting the transmitting recorders on a human being.
  19. In the case of the Sling Studio you can hard wire a 2 channel audio mix directly into the Sling Studio Hub. If the live streaming production is patterned after a typical live TV broadcast, you will have an A1 doing the sound mixing while an A2 makes, or several A2s make, sure that the A1 has some sound to mix. Same as it ever was.
  20. Hi Mike, Thank you for the warning.
  21. Thank you for the suggestion. I have thought about doing something like this, but have never taken the step to try it out. Thank you.

  23. Thank you. I imagine it is a pain to get the wire mesh stuck in the tiny caps but it sure seems like this part is made from $0.05 worth of materials and then a whole lot of *overhead* turns it into a $10 item. It seems like the kind of part that should sell in ten packs for $10 and get drop shipped direct from manufacturer in a small envelope. I can not imagine claiming "lost and damaged" for a part that seems destined to get lost, and when lost is rarely, if ever, caused as a result of carelessness or malice. The darn things just slide off when people are retrieving th
  24. Hello, I like to use B6 mics frequently. Infrequently, but too often, I learn that a protective cap has been dislodged and misplaced while the mic was being removed from talent. The cost of the replacement caps seems unnaturally high at approximately $10 each. Is there a best price source for the protective caps? Thank you.
