  1. Here's my view from last night - front of house at Bob Jones University's first performance of Titanic: The Musical: This is by far the most involved show I have ever run: 49 channels of wireless with a cast of 65+ and 13 wired mics on a 25 piece live orchestra in the pit. The trailer below was shot by our internal media folks at a dress rehearsal. The audio is essentially my front of house mix, so please excuse the large number of open mics at times. We hired 6 professional singers for lead roles, but everyone else - cast, orchestra, crew, and designers - are students, faculty, and staff. EDIT: The embedded video worked for me but doesn't seem to be working for some. Here is a link that may work better: https://www.facebook.com/bjuedu/videos/411084119653155/
  2. So this one was certified in July, before the flurry of ETSI modifications. I should have looked further back.
  3. Geometry seems reasonable for 5-pin lemo... No FCC certifications since November so not likely a new transmitter.
  4. It looks like this has now been accomplished, since firmware v6.0 is now on the web site. From the release notes: VRWB v6.0 - 11 December 2018 Substituted NU Hybrid (NUH) and NU Hybrid with talkback (NTB) for 100 Series and Mode 6 compatibility modes, respectively. Removed REFUMAUS mode. Fixed rounding error in "mhz" serial update command. Thanks to all the folks at Lectrosonics for maintaining compatibility between this now-discontinued product and the current crop of transmitters.
  5. What power would this have been? The original SMV already would have had 50mW - was there an even lower power option available?
  6. I see from snooping the FCC ID database that the re-certifications of all of all current Lectrosonics transmitters have come through in the past few weeks. I have made up a rule that I think works for telling the older units from the newer by the FCC ID on the label: The newer units have an FCC ID that contains an "A" AFTER the band designation. Some examples follow. A simple example is the LMb: FCCID "LMBA1" is LMb in A1 band with 75kHz deviation FCCID "LMBA1A" is LMb in A1 band with ETSI mask compliance and 50kHz deviation. A few are weirder, like the SMWB series where the single- and double-battery models are electrically identical and share the same FCCID. The older models use the single battery model number as the FCCID, but the newer use the double battery model number. However the "A after the band designation" rule still works: FCCID "SMWBA1" is SMWB (and SMDWB) in A1 with 75kHz deviation. FCCID "SMDWBA1A" is SMDWB (and SMWB) in A1 with ETSI mask compliance and 50kHz deviation. For block-wide units, the naming system isn't the same as before either. The older block-wide units shared a common FCCID for several blocks. A band designator of E, L, M, or H corresponded to bands A1, B1, C1, and D1 respectively. Now each block gets its own FCC ID: FCCID "DBZWML" is a WM in block 21, 22, or 23 with 75kHz deviation. FCCID "DBZWM21A" is a WM in block 21 with ETSI mask compliance and 50kHz deviation. Bear in mind that this is unofficial information based on my observations - but I believe it to be accurate.
  7. For a COS11 on an original UM400 you want "universal" figure 5 with the resistor. In fact the universal wiring should work for ANY Lectrosonics transmitter with a TA5F connector. If you know you will only be using UM400a or newer, then you may choose to use the "servo bias" figure 11 without the resistor instead. But figure 11 is not for the original UM400.
  8. We had some SMa (which, I believe, is electrically identical to SMDa except for the dual batteries) for a while and it was my experience that the batteries did run down after being in the transmitter a while. But never so much as to make a noticeable difference just overnight. Any chance you always use the same set of batteries and one is bad? Depending on the way the dual battery setup is implemented internally it could be possible for a bad battery to slowly drain the other - but not fast enough to notice under normal use. As a point of reference, our SMa transmitters would go about 1.5 hours on an alkaline and about 4.25 hours on a lithium. With dual batteries you should be getting in the neighborhood of double that if both batteries are contributing.
  9. I prefer the AKG C34 because it can do stereo. If you have the right rig you can route the signal from each of the four "virtual capsules" to its own wireless transmitter. That way you can wait until post to decide if you want to do mid-side.
  10. I feel your pain because we have tens of thousands of dollars in 600MHz systems that will be illegal in a couple of years too. Some we have been able to get re-blocked, but even though that was less expensive than buying new, it still was a significant cost. Those Sony transmitters look like they have a 30mW power output setting and a 5mW power setting. After July 13, 2020 the legal power limit for operating in the duplex gap and guard band will be 20mW. It is doubtful whether 5mW would be useful and the 30mW setting would be illegal - but if there is no resale value to speak of, it may be worth hanging onto them and seeing how they do.
  11. If nothing else I expect a flurry of transmitter re-certifications - like, this month - or there will be problems with having things to sell. That is, unless there is something about the new rules I don't understand - or someone has set up a shell grantee code to thwart my searches on "dbz"
  12. MCI JH-24. We still have ours here. My time here began during its last days of regular use but we still need it to play stuff from the archives from time to time. Just last week I used it to transfer a 16 track orchestral film score.
  13. Yes, that is the case I have been making for the last few years. It's just that everybody else is making their cases too... Yes, that is true.
  14. Nice for you. I can't answer you about anybody else, but in my situation there is no way I am going to sell our 22 channels 600MHz gear (that are still functional, legal, and that I need to do my job) until I have funding approved to replace them. Because I cannot unilaterally decide where my organization spends its limited resources, all I can do to get funding is to make my best case for the capital expenditure and send my request up the chain of command.
