  1. Lectrosonics SMWB coming soon?

  2. Lectrosonics SRc Receiver Announced

    Without diving into the gritty details - the transmitted signal is an error in a predictor algorithm that has been put back int he analog realm, then converted back into digital again upon pickup by the receiver. This error data is then added to the predictor digital signal in the receiver and then converted into analog audio - the AES endplate is converting the resultant analog signal back into the digital realm. It's complicated but the end result is AES3. Gordon
  3. Lectrosonics SMWB coming soon?

    The beauty of it is, if we find a way to change the rate, or any other improvements in firmware for that matter, you will be able to download the file from our website to a micro SD and update all your units without sending anything back to the dealer or factory. Additionally, there will be no USB driver issues or cables or even having the computer present once the card is loaded. That's why we went this way - the micro USB Port took up just about the same amount of board space and then we would have all those weird USB issues and the need for an update program. The SD card simply made better sense. Once we had the card.......
  4. Lectrosonics SMWB coming soon?

    Correct - the Digital Hybrid is sampled at 44.1 - internal conversion was costly from a current (amperage) and a code space point of view. When I import a 44.1K file into a 48K project into Adobe Premiere, the conversion is quick and simple - I hope it's not a pain in other editing suite platforms - shouldn't be. Nope - it would be nice but US Patent laws apply to US manufacturers inside or outside the US. If we were fully located in Tahiti, we would be able to do so - but probably wouldn't because it would cut too much into beach time........ Gordon

    Gordon answers - Patents.....
  6. RIP - Ed Greene

    Ed was a really mellow guy - his input in our early days made all the difference. His patience with us beginners when we first came on the scene was just terrific - I will miss him.
  7. Lectro Power Solution

    The SR series receivers with either the SREXT or the SRAES end plates will allow easy externally powering options - the SRAES plate allows you to send AES digital straight to your mixer if it has AES/EBU inputs.
  8. 600mhz equipment resale?

    Don't confuse CE with RF approvals. CE is the consumer protection regulations - Separate RF regulations cover EU approvals for radio gear. CE has no bearing on the radio testing and regulations. All gear sold in the EU (legally) must bear the appropriate approvals for meeting the EU regulations for transmitters (50kHz deviation, 50 mW power output, SAR testing etc) - said approvals must be done through a certified laboratory and the various nations notified through a "Notifying Body" - typically a division of the test labs. So, a US unit certified under FCC regulations cannot be sold in the EU. Yes, it can be modified to meet the EU regulations but still won't have the proper approvals marks (CE is NOT enough - and the radios must have both CE and RF approvals) . The reverse holds true as well - an EU certified unit is not US legal unless that device is the same in both markets. The NEW regulations that take effect in October of 2018 for US products will be compliant with the EU regulations (except for allowed power levels, which are higher for Part 74 - that's you guys). For any lower powered units (<50mW), we will be able to have them tested and certified for both markets - and carry dual approvals. Units that are capable of higher power cannot get EU RF approvals if they are wireless microphones operating in the normal UHF bands. Messy - and very expensive - business. Testing costs are ridiculous anymore.
  9. T-Mobile to begin rollout of 600 MHz spectrum this summer.

    Blocks 24, 25, 26 will eventually go away, forced off the air by both regulatory mandate (FCC rules) and by physics (the cell transmissions will blow you off the air). That will take time - how long depends on the speed of the execution of the auction reallocation of TV stations and the speed of infrastructure construction by the cell companies who won spectrum in the auction. The ultimate regulatory deadline is July 13, 2020. As far as affecting production for wireless manufacturers - it means we are discouraging US buyers from buying anything in the 600MHz bands now - Blocks 24, 25 and 26 (Band C) - unless you have a valid economic reason to buy now and change later (long term contract that gives you a good return on buying now and using for the next three years as an example). These blocks are still sold elsewhere so we are still building them but we must cease selling them in the US by October 13, 2018. As far as the rest of the 600MHz spectrum NOT owned by T-Mobile (who has the most ambitious implementation plan) - there are numerous other buyers and their rate of adaptation and implementation will vary. Some may not even be up and running by 2020 - it's very hard to predict the future - as others have pointed out, the 700MHz band is not yet fully implemented and it has been 8 years. So, if I owned a Lectro block 26, what would I do? I would first check to see if it can be block changed to a lower block - that is certainly a more cost effective method than any rebates or trade-ins. Several recent models still have that option available. Check with the factory. If so, then wait until you have a good time for a changeup - (you have until 2020) and then get it changed. If it is a really old legacy product where certain parts are no longer available so block or freq changes cannot be done, then I would consider selling it ASAP before the rush or working it to death until it can't be used any longer (legally or physically, whichever comes first), then selling it overseas via eBay and upgrading to the latest generation. If it is THAT old, you got good life out it and an upgrade to the newer gear will give you new capabilities. The good news is that you don't have to act immediately - but act eventually you must. There's no rush, no panic - you will simply notice it getting tougher to us as new stuff starts firing up. Gordon
  10. Need 3 wirless mics

    And the 620-670 is going away. and that FCC-ID number is .......... ?? It should be on a label on either transmitter or receiver. Generally a 6 character alphanumeric - the Label will also have the frequency range
  11. Need 3 wirless mics

    What's the FCC-ID on those wireless? - I sure can't find it on the FCC website. Their website does, in fact, tout their factory in China - and their operational frequency (610-680) does NOT comply with the new regulations based on their published information (608-614 is off limits to wireless mics) About Us GTD Audio Inc, is a professional audio equipment manufacturer.

    Just remember, T-Mobile didn't buy the whole spectrum - just a few 5Mhz blocks - they can't wipe it out singlehanded......
  13. Interesting new wireless system

    Too true, I've been interviewed at trade shows showing our gear while using someone else wireless for the interview - we all just get a good laugh out of it.
  14. Lectro SRc field reports?

    Good afternoon, all, The SRC problems reported early on centered on vulnerability to high power sources in the 450 band - typically walkie talkies. There was a fairly high incidence of reports involving A1, fewer for B1 and even fewer for the C1 band. Keep in mind that since each involves a different group of frequencies, each is a discrete design with variances in components. In September, the A1's were resolved with a systemic RF board design change. The fewer B1 units we received got a change up of a number of components to correct them - it wasn't pandemic in the B1 band - most seemed great but a few had hiccups. The C1's were even fewer in number and in some cases the fixes that helped in the lower bands weren't as effective. B1 and C1 have the same basic board revs. It's hard to determine the serial numbers involved (like a changeover point) because we went back and upgraded a number of units in stock that were not sequential. So, we have been handling it on an as needed basis for units exhibiting issues. As always, our engineers can never leave a design alone for long and we have been working on continued improvements for the SRC due to some export frequency bands from which we learned new tricks and incorporated that in to new board spins. So, officially, we feel the A1 and B1 bands are now solid. C1 is also very good but randomly we encounter one or two that hiccups - we are getting very good at catching that in QC. (Half the battle was duplicating the circumstances) If you are having issues, contact our service department - it a warranty thing. Units going out the door - as testified by many happy users now - are working well. Just remember, not all interference problems are traceable to the design corrections we have found. Often it is environmental coming from a source that we don't know about. The coordination looks good but there is another unknown RF source in the neighborhood that just messes with everything. My point is that not every symptom is the result of early design glitches - but regardless, you know we will take care of you. Larry will hunt me down otherwise - and he gets especially grumpy without his hammock time.............
  15. UCR411a select buttons beep

    Thee is no beeper designed into the UCR411a or transducer of any type. The only thing I can think of would be a faint noise either from the physical button squeaking along the side of the hole in the panel or perhaps a very faint change in oscillation of the controller for the LCD display as the display reacts to the button push. (LCD's and their support circuits can "whine" at extremely low levels) If that's the case, I want your hearing!
