  1. I'm trying to find a wiring diagram for these WL183/184/185 lavs with Zaxcom Lemo3 (TRXLA 3.3v). Shure's Lemo3 wiring leaves the mic with quite a bit of hiss/noise floor (too much in my opinion). To connect a Shure lapel mic (e.g., WL183) or headworn mic (e.g., WBH53) to the Shure WA336 Lemo 3 connector: Shure black wire (audio) and Shure cable shield (ground) to Lemo pin 1 Shure red wire (bias) to Lemo pin 3
  2. Good question, Trey. I'm mostly using Normal Sensitivity Cos11D's and I've had them clip (if a cast person laughs/pipes up or happens to look right down into their lav - working on a ladder looking up talking, then looking down talking - that can be a ~20db swing). I understand this clipping is possible because the Cos11D are slightly underpowered by 3volt Zaxcom Transmitters, so they clip out before the advertised dynamic range. This shortcoming basically defeats the TX's "Neverclip". I too keep my MRX's at 0/unity and ride TX gains too, but now I'm wondering if I (too) go lower on the Packs and make it up at the Nova. I just wish the older transmitters could properly power a Cos11D, because I personally like them better than the 4063/6060.
  3. Double-check that you're plugging the cup into that one Hirose 4 lightly-labelled DC IN (on top far right). I know this might also sound obvious, but I remember seeing another post a while back where a user went into one of the other 8 Hirose's (which are the outputs). The interesting thing is it will still pass Power if you went in/out on those 8 (like a passive splitter)... but data/telelmetry can only come in on that one IN port. Might be easy to miss this in a dark bag/cart/rack.
  4. Looks like RX8 is coming next week according to an update Glenn made yesterday on the Zaxcom facebook group. 👍👍
  5. I agree about the bg music, but I don’t believe there would be any artifacts as it’s 100% digital. I got to demo an Axient rack system a couple weeks back and the range does seem to be unmatched (especially based and at such low RF power settings). They have the tiny internal antenna’d transmitters, they just need to figure out a bag sized receiver. And if they can somehow get their 2.4ghz Showlink remote control tx integrated, it would be a welcome disruption.
  6. Any update on the RX8 release?
  7. Hi Larry, I have found myself wiring some Shure 184's for Lectrosonics TA5. Can you clarify if when you suggested running the black AUDIO wire to pin 1/Ground without the resistor, you mean **instead** of going to Pin 5 at all? Or... Black wire to Pin 5 + Ground? Thanks! -Jim
  8. I experienced similar issues using that same exact setup (SNA600a's/PSC Multi/SRc's&Srb). I brought it up recently on one of the sound facebook groups and it was interesting to see many other mixers say they also witnessed the same issues (taking hits) and many of them had abandoned that rig all together for bag use. I too have since abandoned it. The dipoles do offer more gain (you can see it in the scans - compared to whips) and I believe that gain is overloading the receivers front end? It can't help to be running a hop transmitter less than 12" away either (and most of us are in a bag rig). That said... the dipoles do out perform the whips by almost double the distance (according to my field test) however the unfortunate trade-off is that they don't do well at close range (approx less than 50'). Perhaps Lectrosonics might design a SNA600B (B for "bag", optimized with an attenuator and/or PSC could offer some adjustable band pass filtering/attenuation) until then I'm sticking with whips in my bag. PS I considered trying 1 Dipole & 1 Whip, for 'best of both worlds' but as the OP pointed out: the RF signal isn't dropping when these hits/dropouts happen - so I believe diversity-wise, the RX would still choose the channel with the most gain. Too afraid to find out though ;)
  9. Good news for the B1 folks... I just received a UPS notification that my SRc-B1 now has the new rev board in it and it's on route to me 👍
  10. Do you know if your unit received the new PCB?
  11. I sent my SRc-B1 back to Lectrosonics late Nov 2017. Here's the latest update from Lectro (last week): "I didn’t see the post (*referring to this JW thread*), but it is at least partially right. We were applying a component update to correct the range issues with SRC, however during that time, our engineering dept was working to have a new pcb made which would implement the update as well as other improvements they wanted to incorporate to better its performance. The boards are close to being ready, but it could be awhile before we have boards available for the units I currently have in-house to receive the update. I’m sorry I can’t be more specific, but I don’t have a firm ETA from engineering yet. I know they are still in the testing process. If you’d like, I can return your receiver, or we can continue to hang on to it to wait for the new pcb." I'm happy to leave it there until it's figured out.
  12. "You Don't Know How It Feels" was one of my favorite songs to reference an unfamiliar PA system. You can almost mix the song with a graphic EQ. Timeless music - never sounded dated to me.
  13. Thanks Jan for the info. I'm still curious regarding the ID of the receivers... Where can I enjoy this telemetry information? Via a TCX-2 in transmitter mode? Or using different model Betso products/software?
  14. The video isn't showcasing RF interference. It's showing how these units react if/when another TCX-2 transmitter (assigned to the same channel) comes within range (spoiler: nothing happens, until the first tx goes out of range - then the other takes over - but again this is a short unscientific test). These units can be named with 20 different ID numbers, but I'm not sure what the intended purpose is of that is. Perhaps there is software coming? Probably a question for Betso.
