beartrax Posted June 28, 2014 Report Share Posted June 28, 2014 an option that has worked for me on a few productions is using my lectrosonics tx in ifb mode then affixing r1 (r1a) rx to cameras and distributing r1/a for production listening as well, i like using a single tx for dual purpose, all in all not too bad on the budget either there are many options for tx... t-1 /t-2 /t-4 or even um400a / uh400a / hh / or any sm variety … i typically just use a single mono mix because it's only a scratch to camera and production doesn't need stereo … i have cables to feed 2 ch input of camera if needed, i have quite a few r1/a rx so this is a good fit for me... i can easily feed a few cameras and have a bag full for production … r1/a run for 5-6hrs on 1 9v battery, i put a little tape on the volume knob when r1a is on camera so level doesn't accidentally get moved … all in all seems to work well for me, as you know many ways to do this depending on resources and production .. something i really like about this is i can tx at 250mw so with a a good frequency range is excellent, of course good separation & coordination with your other frequency blocks is key at 250mw ... also if i need more rx i can run 400 & sr series rx in fib mode in the same block and pick up the audio as well and if available i can take advantage of a slot camera if using sr Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted June 28, 2014 Report Share Posted June 28, 2014 Is there a difference in quality when you put a Lectrosonics in IFB mode? Quote Link to comment Share on other sites More sharing options...
BAB414 Posted June 28, 2014 Report Share Posted June 28, 2014 I use G3s for mono mix hops and SRbs for stereo hops when necessary. The problem is powering the SRb which on some cameras you get away with a p-tap out. On c300s and DSLRs etc, you'll need the batt sled.

Due to the flexibility of digital signal processing, the UCR411A is also able to operate with Lectrosonics 200 Series, Lectrosonics 100 Series, IFB Mode, as well as Modes 3 and 6, which work with certain non-Lectrosonics transmitters.

beartrax Posted June 28, 2014 Report Share Posted June 28, 2014 I'm curious as to way even use the IFB mode then? What's the advantage? why do anything … because we can … but seriously i'm not sure what aspect of the use you're questioning … are you wondering why use it if it's a slightly lesser quality…? for me i like to use this method, as i stated above, for the convenience of a single tx handling production monitoring and camera hops simultaneously using gear that i already have handy … and sometimes i like the idea of have my hops & ifb at 250mw, and when i'm working as a 1 man audio dept out of a bad it's been a good fit for some productions i thought i'd mention this set up i have used because the price tag isn't too bad if someone was looking to purchase a different way to hop … plus depending on what pieces are paired together there can be desirable flexibility … you can get a 411 (or 401) smqv (or um-uh 400a) and r1/a(s) and have the option of talent mic in hybrid mode or hop + ifb in ifb mode … of course there's other ways you can get these pieces to work for a given scenario … most any set up will have some limitation of sorts depending on the production … this set up doesn't offer tc & recording or aes, however when i've used this set up nothing more was required than it was capable of, if the production requires more then i reach for something else Quote Link to comment Share on other sites More sharing options...
LarryF Posted June 28, 2014 Report Share Posted June 28, 2014 The R1(a) receiver was (is) a single band compander system with pre-emphasis and a maximum deviation of 20 kHz and a frequency response that starts to fall off at 15 kHz. Frankly, they sound better than they should. Remember, this was designed for IFB. The only reason to use IFB mode is if you have an R1(a) receiver in the receiving mix. Otherwise use the 400 mode (digital hybrid) for better frequency response (22k), noise suppression, much wider deviation and lower distortion. However, to paraphrase the 70's "If it sounds good, do it!" Best, Larry F Lectro Quote Link to comment Share on other sites More sharing options...

Mirror Posted June 28, 2014 Report Share Posted June 28, 2014 @beartrax, Ah, I think I get what you're saying. You use the IFB mode because you can use multiple IFB receivers, which are cheaper to buy, as opposed to using multiple 411 receivers all tuned to the same frequency (more money). EDIT... I see Larry and Mike both posted with the answer while I was typing my response. Quote Link to comment Share on other sites More sharing options...

Mungo Posted June 29, 2014 Report Share Posted June 29, 2014 Hi Jeff, if I had to buy new hops now, I would try out the Sony UWP-D. It's very very very cost effective for Digital Hybrid, has true diversity receivers with audio out for camera/mixer and also a headphone out for anyone listening on set. So you need to buy only one transmitter and multiple receivers. The biggest advantage of them is the possibility to power them via USB. Plug power in and forget. Almost any cam has a USB jack, professional and semi and radio shack. I haven't tried them yet, but the idea is great I think. You only need a lav mic from another manufacturer if you use it as a wireless microphone transmitting system because Sony's lavs seem to sound very poor. Greets!

Jeff Wexler Posted June 29, 2014 Report Share Posted June 29, 2014 Based on your suggestion, I looked into the SONY UWP-D series wireless --- quite impressive and so reasonably priced! I'm trying to figure out what's wrong with them, to offer that much flexibility and features in a rugged package for that price. It is a digital hybrid though it is not exactly clear what they are doing --- they talk about using a digital compander before transmitting (analog transmission of course) which I guess is how digital-hybrids generally work. Also, it is a true receiver diversity system which is a good thing. I would love to hear from someone who has had some real world experience with these SONYs.

Mungo Interesting inexpensive option for sure. Reading the specs though it seems the rx only outputs mic level. I prefer to go line into the camera if possible. However if the headphone out is loud enough they would make a decent ifb feed for not too much money. Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted June 29, 2014 Report Share Posted June 29, 2014 Some people do something similar with the Sennheiser G3 series. Receiver as reference hop on camera and the IEM versions for IFB all being fed by a single transmitter. I got a little mixed up. I was once told about a show doing it "one man band" put the talent mic in IFB mode so the producer could listen and the camera's 411 receiving IFB mode. That's a different situation because they are never getting the talent mic at full quality. This is different. Quote Link to comment Share on other sites More sharing options...

Jack Norflus Posted June 29, 2014 Report Share Posted June 29, 2014 I don't have any direct experience with the UWP-D series. But I have used other Sony wirless in the past and I have to say I was quite disappointed with the range. But like I said this was an older analog system.

Not only the range was bad but the sound wasn't great either. The analog companding was nasty sounding. Quote Link to comment Share on other sites More sharing options...
