  2. Please contact our Parts & Repair dept. and ask for Gerald. I've prepped him with your question. 800-821-1121 It seems that E01 (Europe) firmware is loaded on this unit. Yours, a domestic unit, should be loaded with one of the first four firmware versions on this page: https://lectrosonics.com/firmware/category/174-smwb-series-firmware.html There are details on that page of how to know which version you need, but if you are uncomfortable with any of that, give us a call and chat with Gerald.
  3. Yes, Vector Diversity is used when you can combine two of the channels. You can do that with each pair (channels 1 & 2, and channels 3 & 4). Thus, you could have a 3-channel receiver with one Vector pair and two channels using antenna phase switching (like our UCR411a, Venue 2, etc.) We plan to work with Aaton to make the Hydra compatible with the DSR4, yes.
  4. Yes, the DSR4 has an IP3 of +15 dBm whereas on the SRc it is +5 or so. In the scenario you described, the DSR4 (like the DCR822) should hold up better than the SRC does.
  5. New answer! The Superslot spec has the same pins carrying two balanced analog channels, and two AES 3 channel pairs. So, with the DSR4 receiver, channels 1 & 2 would be on balanced pair pins 1 (gnd), 2(+) and 3(-) and then channels 3 & 4 would be on pins 1 (gnd),, 18(+) and 19(-). This means the Octopack, and similar analog distro/slot units can support 4 channels per slot, if the receivers are set to AES outputs.
  6. The backplates for the DSR4 will be the same size as the older ones (for the SR Series) and in fact the older ones will fit on the new 4-channel receiver. They will even power it and you can get channels 1 & 2 out of them. However, for the full functionality with the new receiver (4 audio channels out via analog or AES3 on the DSR4EXT, or two AES pairs via DB25), you'll need the new plates. No provisition for direct headphone out on this unit - just nowhere to put that. No other remote control in this receiver.
  7. The question is (or should be) what's the cost per channel? $4,500/4 puts it near the lowest cost per channel available in a self-contained portable receiver. The antenna phase switched diversity (for 4-channel operation) is similar to what we've used in the UCR411A, Venue 2, etc. but revised specifically for this model. It works very well.

    IFBlue

    We have B1 units in stock at the HQ, C1 units are slightly backordered and should be caught up within a short time. Any Lectrosonics authorized dealer in Europe has access to the IFBlue units and can order them for you. Also JBK in France has IFBlue units in stock, in the A1, B1, and C1 bands. https://jbkaudioshop.com/en/search?q=ifblue
  9. Congratulations to Mac Ruth, Mark Mangini, Theo Green, Doug Hemphill and Ron Bartlett for their Oscar win for best Sound! And congratulations to all the nominees for their fine work on Belfast, No Time to Die, West Side Story, and The Power of the Dog. For all the details: https://abc.com/shows/oscars/news/winners/oscars-2022-nominations-sound
  10. There are a few operational reasons why the receiver doesn't recognize pilot tone: 1. The compat mode has changed. Make sure the same compat mode is selected in the transmitter and receiver. The default for standard US product would be "NU Hybrid". 2. If your system is in the A1 frequency band, there may be a mismatch of pilot tone frequencies if you are operating on a frequency between 486.400 and 495.600 MHz. This frequency range is common to both Block 470 and Block 19, so both the transmitter and receiver have to be on the same frequency AND the same block. 3. If your transmitter audio gain is set far too low, the receiver can squelch (mute audio) even at normal distances. Your audio gain should be set on the transmitter so that peaks in the audio trigger the -20 modulation LED to blink red briefly.
  11. The Wireless Guide from Lectrosonics mentioned above is a booklet. You may also want to watch this series of videos "Wireless Side Chats" starting with the basics and getting into advanced topics:
  12. Different genre but one of the most amazing performances of anything ever is this one of Tchaikovsky's sextet "Souvenir de Florence". Just incredible, virtuosic playing, ensemble work, and musicianship all around. Very well recorded, too - clean, clear and dynamic. Looks like it might just be the two Schoeps omnis.
  13. The V2 hardware update in the DSQD has been in place since the December 2020/January 2021 production runs. Part of the reason for the change was that we had to design out any AKM parts since their factory (for A/D and D/A converters) burned down in fall of 2020. The difference in performance between Vector Diversity in the V2 version, and Ratio Diversity in the V1 version are very subtle and will not be noticed by most users. This is because the DSQD platform wasn't designed from the ground up for Vector, the way the DCR822 was. So, getting Vector Diversity shouldn’t be reason alone for someone to upgrade their units (a $1,500 cost to replace both boards, by the way). The way to tell if a unit is V1 or V2 is by looking at the firmware either during bootup or looking at the "About" screen in the Tools & Settings menu. If the unit is running firmware v1.xx.xx then it is a V1 version. If running 2.xx.xx then it is V2. And, if you go to update a unit using Wireless Designer, it will know which version you have an install the correct update.
  14. Dejan, bias of 4v works just fine with the DPA lav mics and 4099s, etc. In fact, I'm doing a setup right now with our SSM and some 4099s, and they sound great together. I do set the load impedance to "0" instead of low, though, for more sensitivity with this particular mic. That is always an option.
  15. Looks like the PLL has come unlocked. We should take a look at that unit in our service dept.
  16. Vector Diversity is available in digital and Hybrid modes in the DCR822 and in the DSQD V2. I would say, though, that Vector yields more of an improvement over standard ratio diversity when using digital modes.
  17. Off and on for some years now we have had reports of a “whine” at 2.75 kHz in the audio of the SMWB family transmitters. For the customers experiencing this issue, the short term “bandage” has been to turn off the remote capability of the unit. Units that were sent in to our service department received replacement circuit boards. In other words, this has not been an ideal situation. I have good news! Our intrepid programmers have found a way to solve this problem purely in firmware. Thus, we have now published updates for ALL versions of the SMWB family transmitters, including models specific to International markets, and even for those models with older hardware made prior to mid-2019. All of the specifics of all the different versions, with full revision history for each are here: https://lectrosonics.com/firmware/category/174-smwb-series-firmware.html Please note that it is extremely important that you follow the information on that page carefully. Because we have made these transmitters for more than 4 years, there are different hardware versions out there. Installing the wrong firmware can “brick” these units, requiring further handholding that I’m certain we all want to avoid. The instructions for the process of updating the firmware in these units is in the manual on p. 18. https://lectrosonics.com/downloads/category/61-transmitters.html?download=736:smwb-manual-all-models We are here to help! If you have ANY QUESTIONS or have any doubt about this process or which version to install on a given unit, please contact us at 800-821-1121 (US) or +1 (505) 892-4501 email is service.repair@lectrosonics.com
  18. Update: we dug through the archives from a few years back and found the background info on why we "corrected" the polarity of the DPA input setup for the SSM. We found that the original version reversed absolute polarity. With firmware v1.03 this was corrected so that a positive sound pressure at the mic capsule results in a positive voltage on pin 2 of the receiver output. It may be that the A10 system then is "reversed" in this regard.
  19. The end-to-end latency with the SSM and any 3rd-generation Hybrid receiver (SRc, Venue 2) is about 2.9 ms. Your figure for the A10 is correct, thus the difference between the two should be about 0.9 ms. There are several ways to adjust for the polarity mismatch - first, as you suggest, the output polarity in the A10 receiver can be switched to reverse. This can also be done in the Lectrosonics receiver. Also, instead of "DPA" input setup in the SSM, use a custom setup with the following values: Bias 4, Reistance Lo, Polarity pos (normally it is "neg" in the standard "DPA" setting). It may be that either the A10 system or the Lectrosonics system reverses polarity in an absolute sense. But if you ever only use one of the systems, you would never notice. It's not something you can typically hear on its own. If the two systems are used for different things, i.e. lav and boom, you might not notice it then, either, since the boom mic is usually a couple of feet away from the voice while the lav is a few inches - the natural delay difference means that you wouldn't necessarily hear a phase cancellation from different signal polarity. But, you might be able to see it in the waveforms.
  20. We have shipped IFBlue receivers in the A1, B1, C1 and 941 bands. Currently, A1, C1 and 941 units are in stock at the HQ (this changes daily, however). And, we have another batch in the works, likely available in late January. The 941 units are compatible with the IFBT4-944 transmitters, although those transmitters offer 8 MHz of tuning range (944-952 MHz) while the IFBlue 941 receivers have a 19 MHz tuning range (941-960 MHz). As long as the transmitter & receivers are on the same frequency, they will work - no pilot tone compat problems in IFB mode.
  21. LuisT, what version of firmware is running in your SSMs? If it is v.1.02 or earlier, we corrected that in v.1.03 and all subsequent versions.
  22. Most likely the display itself would need to be replaced. Contact our Parts & Repair dept. and they can provide the info. 800-821-1121 or service.repair@lectrosonics.com
  23. Jobo, not that I'm aware of. All the USB cables I have laying around here work for me. My only thought is that the connector itself must be fully seated in the receiver micro-B USB socket.
