Prahlad Strickland Posted July 13, 2014 Report Share Posted July 13, 2014 It's my understanding these are around 50hz to 12khz? is that about right? Does anyone have a recording of any audio from an erx2? Are they strictly scratch track or is the audio somewhat useable. 12khz is quite low if that's the low pass Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted July 13, 2014 Report Share Posted July 13, 2014 It's right in line with other ifb systems I've used, r1a ~10k, comtek ~12k. For an ifb system, I think they sound quite good. Quote Link to comment Share on other sites More sharing options...
Ze Frias Posted July 13, 2014 Report Share Posted July 13, 2014 The audio frequency response on the ERXs is from 60Hz to 12kHz, so yes, they would be used for scratch / guide track only, just as you would do with a comtek or r1a. They do sound great though. Quote Link to comment Share on other sites More sharing options...
Prahlad Strickland Posted July 13, 2014 Author Report Share Posted July 13, 2014 good enough for a boom op? for wireless boom also anyone know with the zax camera link if i'd be able to hook up a boom op via the zaxnet, and be able to interupt the boom feed without it also going to the camera? I'm thinking not?, since I think it just has a dual input, not a 3rd dedicated to zaxnet audio...? Quote Link to comment Share on other sites More sharing options...

glenn Posted July 13, 2014 Report Share Posted July 13, 2014 A story related to me last week was that Peter Jackson used the ERX2 for critical monitoring of tracks during the production of the Hobbit movies. The frequency limit of the ERX is not a factor in IFB systems. It is the systems low distortion, absence of noise and direct digital transmission from the Nomad or IFB200 that makes the difference. Just keeping the entire system digital and eliminating multiple A-D and D-A conversions before transmission is a big plus. Glenn Quote Link to comment Share on other sites More sharing options...
Tim M Posted July 13, 2014 Report Share Posted July 13, 2014 Has anyone found any issues relating to reception to be an issue, the show I'm currently working on the cameras each have 2.4Ghz transmitter on them at half a watt for producer monitoring the video signal. With my 1 watt 2.4 zaxnet antenna I can't really reach them from a 50-100ft distance with a solid audio track for scratch. YES I did frequency coordinate the wifi frequencies...there are no intermod or other issues besides possibly receiver desensitization...is there anyway to attach a wifi duplexer? Attaching the transmitter and the ERX to a duplexer and then go through one antenna? Quote Link to comment Share on other sites More sharing options...
JonG Posted July 13, 2014 Report Share Posted July 13, 2014 Tim, Many people use antenna amps to increase range for their 2.4ghz tx. In my experience using an ifb100 at 100mw, I tend to have the stronger signal than the camera video sends, but I recommend to the camera dept to use tx in the 500ghz range instead of 2.4ghz for obvious reasons aside from my amp.

Wandering Ear Posted July 13, 2014 Report Share Posted July 13, 2014 Tim, I have been quite happy with the reach of my 1 watt system. The show I'm on now has 2 cameras with 2x 2.4ghz systems ea (video & preston) and I'm running 2 channels also. I'm running an ifb100 for my boom operators, and that sometimes falls short. The 1 watt has given me great coverage. It fell short when I was in a shed in the woods with video village about 500 feet away with a small hill between us, but picture didn't reach there either.

Glenn What about the Camera link? does that also have the same transmission strength as the nomad or IFB200?, or is it outputting a lower .mw output?

Very good point. I'm very happy with the 16khz that the trx900's stamp, with the DPA 4063, i'm very happy. Quote Link to comment Share on other sites More sharing options...
Prahlad Strickland Posted July 15, 2014 Author Report Share Posted July 15, 2014 The same audio going to the camera is broadcasted via ZaxNet The camera link is 2 channels, does it sum both to mono?, or can you choose to send only boom?

Jack Norflus Posted July 15, 2014 Report Share Posted July 15, 2014 The camera link is 2 channels, does it sum both to mono?, or can you choose to send only boom? Yes zaxnet audio is always summed to mono. In the camera link menu you can chose to send a mono mix, left input only or right input only.

Output power of both the 900cl and the IFB200 are the same. Nomad is slightly, but not much, lower. Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted July 15, 2014 Report Share Posted July 15, 2014 Yes zaxnet audio is always summed to mono. In the camera link menu you can chose to send a mono mix, left input only or right input only. or from a Nomad you can choose to send a specific mix to the ERX (like maybe just the boom and mixer talkback). A few people have said they use the Nomad internal ERX to feed audio to a boom op and another IFB200 or CL to send audio to the camera. Same thing you would do with any other monitoring system that wanted private talkback and/or specific mix to a boom op. You almost can't compare the ERX to other IFB systems. It's fully digital and sounds amazing. You might not get the range of a Comtek, but you get the incredible sound quality. I still own a bunch of Comteks and hand them out to the masses, but when I have a director or scriptie that really needs to hear things, I give them an ERX. Total tangent, I wonder if some people have a hearing loss that makes certain systems sound bad to them. I have had some curse Comteks, but I have also worked with field producers that HATE Lectrosonics IFB and prefer a Comtek 216. Everything was set up right and sounded fine to me. Maybe it's just preference, but I wonder if there is some chance they have a hearing loss and a given model lands in their lost range. Total guess there.

Prahlad Strickland Posted July 15, 2014 Author Report Share Posted July 15, 2014 Laddie, the answers to your questions: 973.835.5000 also 24/7 email tech support i'm going to be honest... sometimes i've asked questions at support, only to get much more thorough and cross referencing answers on here. Their support is amazing, and they always answer. But they aren't always in the field like the fine gentleman on here. e.g. Jack responded, then Johnpaul chimed in, and both guys supplied me with info that crosses into answers + field experience. I also like to ask a few questions, then i'm usually satisfied for a month or so. I'm seasonal, so you don't have to worry, I won't fill up the forum to much.

Mark Posted July 15, 2014 Report Share Posted July 15, 2014 It's good to get some help from members here. It's even better if you download the manuals first and try and find the information yourself. This may even influence your initial questions, and you are more likely to learn more. Quote Link to comment Share on other sites More sharing options...

I have read the maxx manual a few times, and it's revisions. The same with the camear link manual. I could not find the answer to my question in their regarding the .mw output power of the zaxnet transmitter. I agree with you though, and I may have missed something in there. But i'm definately a manual junky Quote Link to comment Share on other sites More sharing options...
