Here's what one of our guys in the machine shop came up with as a possible way to get even closer to the action.

His books are a hoot!

Our Japanese dealer set up a test some years ago in a theater in Tokyo with the sole purpose of finding out "how many channels can we run at once". Part of the issue is that they have 20 MHz available only (4/5 of one of our blocks). But one advantage there is that there is nothing else in that band - it is set aside for wireless mics only. Also, they have a 10 mW RF power limit. We had SMa and SMDa transmitters, specifically made for the Japanese RF band, covering 779-809 MHz. Oh, one more thing: their step size is set to a minimum of 125 kHz. We were able to get 42 channels working simultaneously. Our dealer told us that the most they had gotten before was 38 (which is already a lot!) so they were thrilled with 42. I had done two potential coordinations for the test, but the dealer had done their own as well, and we used theirs.

The newest stuff at the booth was the WM transmitter, and we brought a stainless steel version that weighs twice as much but will withstand even long term exposure to salt water, and the SRb receiver system. We also brought the DNTBOB88 Dante break out box which I understand was featured on a sound cart in the Sound Devices booth also, and was shown by Coffey Sound at the CAS Parade of Carts. Here's a couple of pictures from the show.

For those of you heading to NAB next week, please use this interactive map to locate us in the Central hall (it will be hard to miss us...) booth C1720. http://www.mapyourshow.com/shows/index.cfm?Show_ID=nab13&exhid=100379&booth=C1720&hall=B If you still haven't registered but are considering it, just go here and use code LV4213 for a free exhibits pass: http://registration3.experientevent.com/ShowNAB131/Default.aspx We look forward to seeing you in Las Vegas!

Matt, Please plan to stop by and see us at Lectrosonics, C1720. I'll be happy to show you what's new. Cheers! -Karl

Reminds me of a small poster we made when I was part of the Air Force Band sound team in the 1990s. It read something along those lines, like: Microphones are not magical. Sound Systems are not automatic (at least the weren't back then!) Audio techs are not telepathic!

I just recently went through this. My sister in law sent me a box of cassettes (mostly her demos and some live shows with various bands). I started by setting up, cleaning and aligning my aging Sony 3-head deck. From there, I went through a Sound Devices USB Pre into Audacity. I maxed the levels before clipping while transferring, then did some basic cleanup, fades, and normalizing. Most of the cuts didn't need any help. But the few that did needed some mild EQ to sound best. I was pretty pleased with the results and now plan to mine my own archive of cassettes. Only problem? It takes a gawdawful amount of time!!!

OK, just got word from engineering that this is a known bug in the transmitter fimware, and there is a fix for it. Can you confirm what firmware version is in your SMQV (it shows at startup)?

The SMQV and SRa I'm testing here on my desk for issue this seem to work fine. It does take several seconds for the audio to come back on after unsleep. However, it does work. Let me run this by the guys in engineering to see if they might have an idea as to what's going on. Would you be able to try something? After unlseeping a transmitter and getting no audio, re-tune it to the frequency of the 2nd receiver channel, without turning it off, and see if you get audio then.

Hi Niall - a quick search with IAS software shows that blocks 19 and 24 are "best" in central Albuquerque, with blocks 22, 23 and 25 coming in close behind. Any one of these blocks should handily supply more than six coordinated channels. As for rentals, any of the main shops (LSC, Trew, Gotham, TAI, Coffey, PSS, etc.) should have such systems in their rental stock & ready to ship. Hit me up if you want me to provide an exact frequency coordination once you've got the gear. Also, if you have time, we'd love to have you out for a factory tour.

FWIW most users I've talked to are using the 4061.

"Back Then" it was OK to place an ad for an "Ambitious Young Man". Today, they could still use one out of those three...

Sounds (& looks) live to me, and awesome, too.

Would love to join in but I'll be heading out on Sunday mid-day. However, I'll be around from Friday evening until then, and would enjoy catching up with you guys.

Why does cargo go on ships and shipping go in trucks?

Just to add to the confusion... the actual block of operation does not change - it can't - that's hardware. However, the brain thinks the block has changed, and sends the wrong frequency info to the PLL. Per Larry F: The micro sends an actual frequency request to the PLL in binary, i.e., 631.000 MHz rather than just A6, so it fails (can't lock the phase) and sends an out of lock signal to the micro. Not sure what happens after that. In other words, it no workie.

The Wisycom system is analog, but offers a selectable digital compander with a latency of 0.4 ms. To my knowledge, the only all-digital system with a <1 mS latency is our Quadra IEM system. But that's not an ENG/Production system by any means. Most digital systems, and our Hybrid system, have about 3 mS latency. That's still a tiny fraction of one frame.

Thanks for posting that info, Jan. I'm sorry that I won't be able to make the service since I'll be out of town. Bill was a kind man and I'm glad I got a chance to know him during the past few years. I'll wear the Spy Next Door jacket he gave me with pride this fall.

Is anyone out there using our IFB transmitter (T4 or T1) directly tied to a Telex MS4002 COM station? If so, what DIP switch setting do you have on the IFB transmitter?

The sound quality would be a very close match to a Sennheiser system, since both the transmitter and receiver are emulating the HiDyn Plus scheme. Range should not be affected as long as you are hitting the transmitter with enough audio level. Power consumption would be the same for both the transmitter & receiver as with any other operating mode. The transmitter would still respond to RM remote commands. You are correct that the transmitter battery level indicator in the receiver would NOT work.

Our Digital Hybrid Wireless systems make it possible to run in "native hybrid mode" i.e. no compandor in the audio path, but they can also emulate our own earlier analog systems, such as the 100 Series and the 200 Series. There are also two additional modes to match with other manufacturer's units: Mode 3 matches Sennheiser's HiDyn+ (3000 and 5000 Series units) and Mode 6 matches Shure's (outdated) UHF compandor (not UHF-R). Mode 5 matches our IFB companding scheme. All of these features are not available worldwide, however - but the US models contain all modes. So, one way to do what the OP is after is to set our transmitter to Mode 3, and set the Wisycom receiver to match Sennheiser's HiDyn+.
