  1. Yes, with the DSR4DB25 bottom plate, the DSR4 receiver can be docked in the SL-2 and provide 4 channels of audio in AES format. using two receivers with these bottom plates would give you 8 channels total, just as you've described.
  2. Not particularly well. UHFR "audio reference companding" is quite a bit different from the older "UHF" compandor that they used prior to the UHFR series, and what Mode 6 was based on. It may be OK for scratch, VOG, and the like, but for critical applications, I would not recommend it.
  3. ADJ, if you enable AES outputs on your receiver, then you would need to connect those to an AES input on your 833. Or, analog outputs from your receiver into analog inputs on the 833, which then are converted to digital inside the unit. This latter signal chain involves only one conversion. The AES out from receiver is one conversion (inside the receiver) then into an AES input (resampling) on the mixer. It is still only one conversion to digital, but re-sampled. I would challenge anyone to hear the difference but it might be possible in some circumstances. The question then becomes a practical one: if you are short on analog inputs on your 833, then connecting your receiver to the mixer via AES frees up two analog inputs. Regarding latency: if you are mixing lav and boom to one channel, you will get phasing due to the difference of acoustic delay (boom further away) between the two channels. It will vary depending on the difference of distance. The electronic latency won't change unless you change the way the units are connected (re-sampling does introduce a small amount of delay, usually well under 1 ms).
  4. The SRc and the Wisy units output analog from the receivers, so there is an A/D step either in the receiver bottom plate (if using an AES output bottom plate) or in the mixer input, so a conversion step will happen either way. This is of course different for receivers with direct digital outputs like the Lectro 822 or DSR4, Zax, Audio LTD, etc.
  5. No, there isn't a battery eliminator for the LMb. -Karl
  6. Hi Constantin, as it turns out, the DSR4 output routing will be simple on one hand, but also (I think) meet your needs. There are two output sets: one for "jack 1" and one for "jack 2". You can choose either AES3 or Analog for each jack set. For instance, Jack set 1 can be set to "AES3" and on the two balanced pairs, you'll get all four receiver channels in two AES3 pairs. Then, on Jack 2, you can choose analog, and get receiver channels 3 and 4. If you'd rather have 1 and 2 analog for your redundant scenario, then set Jack 2 to AES3 (you'll get all four channels) and then choose analog for Jack 1 and you'll get receiver channels 1 & 2 in analog format. For the case where you want "receiver channels 1 and 3 analog while all four are digital out of the other jack" the workaround is to change which receiver channels are receiving which transmitters. I hope that makes sense!
  7. SMA type 3dB attenuators should work very well in that application. If you are getting plenty of range with say 25 mW coming out of your hop transmitter/s, then this is a good option. They will make the antenna/base connector about 3/4" longer, as Jason mentioned.
  8. According to our engineering team, there are some tradeoffs when trying to solve this issue where both analog and digital outputs would be active simultaneously per receiver channel. I'll be chatting more with engineering next week to see what those tradeoffs are and how they might impact the product overall including delivery times.
  9. You'll be able to choose routing options in the menu just like in the DCR822, but with 4 channels rather than 2.
  10. Ben, so sorry I missed your question back in June! Yes, you can use the DSR4 exactly as you've described - you can set any two channels up to act as a "stereo receiver pair" to output the two audio channels from that stereo signal.
  11. Jason, I understand you talked to Gerald in our service department about your concerns. Was he able to answer your questions?

    WTF

    Thanks for posting that, Mono. I've always liked Laurie Anderson - she's always been incredibly innovative. And her point about "stories" as the basis of all her work is instructive. Stories are the basis of all of our work, when it comes down to it.
  13. There is talk of it! We need another programmer, though, so if you know anyone good, please send them our way.
  14. Thanks for posting this, Doc. I know Kelly is excited to man the Lectro table there, and we'll have the latest goodies to show! We hope to see a lot of the production audio community there. If nothing else, stop by for a T-shirt!
  15. We will still service them as long as possible - we always reserve a certain numbers of boards and parts for this purpose. In terms of an alternative, the DCR822 was designed to A) fit in the same space with the same cross section, and provide top notch performance while offering 2 channels, 6 blocks tuning range, on-board recording and Wireless Designer hookup. The UCR411a has an IP3 of +8 while the IP3 of the DCR822 is +15. And, you can still use your Hybrid transmitters with the 822.
  16. Kasey knows his stuff, too - you're in good hands. -Karl
  17. 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.
  18. 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.
  19. 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.
  20. 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.
  21. 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.
  22. 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
