  1. Looking Into Buying Zaxcom IFB

    I've owned and used Lectrosonics R1a receivers in years past and currently own and use Comtek PR-216 receivers, but its time for a change in that the Comteks just aren't performing as reliably as needed. The signal needs to be consistently clean and clear as the client's opinion of my work is influenced by what they hear over IFB. R1a receivers are rock solid and sound fine, but I want to get away from using 9v with a battery life of 8 hours per alkaline. The several days a Comtek will go between battery changes is exceptional, but the 10mw M-216 Option P7 transmitter and plastic case on the receivers have been weak points. So I'm considering Zaxcom for IFB because it's the other option I don’t have experience with, and maybe I've been missing out all this time? What's your experience with an IFB200 to ERX3TCD? In particular, is the range reliably up to 100’ with Zaxnet using 2.4Ghz? Seems like there are so many devices using 2.4Ghz with everyone having a smart phone etc etc that interference could be an issue.
  2. Hey Sound Peeps! There is a host of affordable [cheap] chinese radios that reach up to 520 MHz. I was wondering if anyone had experience transmitting in the 420 Block and using these as comtek substitutes. At $15-25 dollars a piece, it's hard to not consider handing them out to crew instead of comteks or lectro ifb's. The only consideration is if the narrow fm receiver works well enough with a wide fm transmitter to make it acceptably intelligible. This is what I'm thinking about: https://www.aliexpress.com/item/6pcs-Mini-Walkie-Talkie-Retevis-RT22-Long-Range-UHF-400-480MHz-16CH-CTCSS-DCS-TOT-VOX/32741929692.html?spm=2114.01010208.3.265.2RrKbv&ws_ab_test=searchweb0_0,searchweb201602_3_10065_10068_10084_10083_10080_10082_10081_10060_10061_10062_10056_10055_10037_10054_10033_10059_10032_10078_10079_10077_10073_10070_10052_423_10050_10051,searchweb201603_2&btsid=70ad5d16-83dc-458f-a072-9e0910497ff7 I've tested these units and they actually transmit and receive up to 520 MHz, though you'd turn off the TX in this application. The other consideration is that the audio output is a 2.5 mm jack so you would need a 'step up' adaptor to 3.5 mm, but at that price.... Any input? Thanks, dB
  3. I had an interesting issue crop up a few days ago. I have two Comtek feeds: one for my crew and one for Production (which includes Director & Scripty, as well as agency types in VV.) Transmitters are two BST-25 216. So I was working on a commercial shoot in a home. My cart ended up in a corner in the kitchen, and I installed my two Mini-Mite antennas upside down so as not to hit the ceiling. Everything was tested, no problems found. At some point, a four-foot Kino fixture with four bulbs was put next to the car, vertically. It was connected to a Variac dimmer, at what I would call minimal intensity. After all adjustments were made, the light ended up about one foot from the Mini-Mite, directly in the path to where Director and Scripty were seated, some 25' away. Eventually (don't know the timeframe, it was a pretty busy and tense set) we heard that the signal is "cutting out". My boom op checked and, indeed, it was cutting in and out intermittently. We moved the cart to get a clear line of sight to them and it mostly was resolved. Unfortunately, we were short on time and dealing with a difficult shoot, so there wasn't much time to test and troubleshoot properly, so I can't share any more information - but I'd love to hear comments or experiences from my colleagues, in case the issue crops up again. TIA, BK
  4. Phonak with a Lecto R1a

    I have a project coming up where talent will need in ear monitoring with an earwig. I know that different discussions on this topic have been discussed before, but I'm not finding my answer. Can I use a Phonak with a Lectrosonics R1a using some kind of neck loop? I'm thinking that the R1a will give me a better range than the Comtek. Have any of you used an earwig in this way before? Or is there another way to get good range with the Phonak? Any advice would be much appreciated!
  5. IFB UM400a Audio Fades Away

    Seeing if anyone has had this issue with the Lectrosonics UM400a BLK 26 in IFB mode. The issue encountered is, after about 10 min of good strong audio sending to multiple R1a units on set. The audio just fades away, comes back and then fade away. Here are all the things tried and observed to solve the issue. When I send it back to Lectrosonics how should I describe it? So I don't get a message back "We can't find anything wrong." because it looks and acts fine at first, but it seems to take a few minutes for it to happen. Thanks Observations: 1. Still solid green power light on UM400a 2. Green modulation on audio lights on UM400a 3. 3 other identical setup bag rigs with own IFB UM400a on other frequencies (swapped with others for testing) same result with bad unit 4. Sound Devices 664 x1 out put is used on all bags (swapped with others for testing) same result 5. Ta3 -Ta5 cables (swapped with others for testing) same result 6. Uses 9v eliminator (swapped with others for testing) same result 7. IFB is five frequency blocks away from nearest other Lectros on set and changed multiple times to clear channels and checked with other bags IFB to not be intermod. 8. Power cycle unit for 30 sec. fixes issue for about 10 minutes 9. Running just one bag or all bags with IFBs and same result with bad unit
  6. Comtek Range, M216 Vs M216-P7 vs BST75

    I'm investing in a Comtek system to compliment my (rather extensive and elaborate) ERX2 IFB config. I've read the all the literature I can find. Looking for practical guidance on the difference performance in terms of range and fidelity of the following: M216 (10 mw) M216-P7 (10 mw) (will these either of these two cut if for cart use with the right antenna configuration? I'd like to go this route if realistic. I heard a M216 raised on the mast works quite well for some.) BST75 (100 mw) Thanks in advance. - Patrick
  7. New ERX cases

    We are adding a case for the Zaxcom ERX's to our line up. We are expecting to be shipping these in the beginning of August and we expect the retail price to be less than $15 US. We are also looking for feed back on the design of the case since we are still making minor changes to it. Here are photos of the prototype.
  8. As suggested by Jim, here is a single thread suitable for updating information and discussing current issues and activities that affect the radio spectrum we use in our work, particularly for our wireless systems. As Jim suggested I "moderate" this thread, please feel free to post information here, and I'll advise if there are any concerns... OK ??
  9. Hi I've been researching quiet a lot on wireless video solutions and found out that the Teradek Cube 155 might be the best solution there is at the moment for boom op. reality, documentary ect. It seems that the latency that there is, happens in the receiver (the iOS device). My question is: with the so much faster processors and wi-fi parts in the latest models, compared to the earlier, iPhone 4, iPad1 ect, Does anybody know the latency when the Cube is used as a stand alone device with a direct connection to the latest i-devices? And is it possible to use it with audio, as IFB? or are there still a lot more latency when sound is being embedded to the wi-fi signal? Will the use of more than one iOS device on the same Cube 155 signal increase the latency? I hope that there is some users out there that knows about this. Thank you very much
  10. Fine people of the forums, I was curious to know if any one out there in low budget land or else where has come upon a more affordable solution to providing headphones to Director an/or scripty than the standard comtek or zaxcomm IFB? I recently came across something that I thought I'd share and see who is with me on this one... I'm currently running Sennheiser RS160 wireless headphones. $150 on eBay then $100 per extra set of cans. Check 'em out here: http://en-us.sennheiser.com/wireless-headphones-digital-stereo-rs-160 Basically, you send a stereo feed to a 1/8" TRS mini-jack on a small Tx base station (runs on 2xAA not included) and it then sends that mix out to as many as 4 sets of cans. Each HP set has its own power and volume controls and the cans run on 2 AAA batteries (eneloop batteries are included!). So on a small indie set these have worked great so far. Range is stated at 60ft which doesn't sound like much but I have not run into any issues on range. There is an ever so slight delay though as it uses 2.4Ghz which is the same as WiFi. Thoughts? Comments? Concerns? Please do tell!
  11. Wondering if these would be any good for a IFB / reference track for camera. Cheap as chips. Obviously won't be as good as usual suspects (Lectro, Comtek, Senn) Anyone? http://www.thomann.de/ie/the_tbone_tour_guidetg_16_r.htm http://www.thomann.de/ie/the_tbone_tour_guide_16_t.htm http://www.thomann.de/ie/the_tbone_tour_guide_tg_c2.htm
  12. Hey Guys, Curious what people are using for your boom operators to listen on. Comtek? Lectro IFB? Zaxcom IFB? Hard wired? (duplex cable?) Boom box? Or maybe listen off the signal pre-recorder with a SD MM1?
  13. Zaxcom ERX2TCD Timecode Cable

    I am looking to get a Zaxcom ERX2TCD soon to send audio and timecode to camera (most often a RED Epic) but I am having a difficult time understanding what type of cable I will need in order to send both signals to the camera. I have a Nomad 6 and will be using the onboard Zaxnet for IFB transmission. But for the ERX onboard the camera, I am wondering if I need just a basic 1/8" cable from the ERX to the mic input on the Epic or a 1/8" from the ERX to an 1/8" and 4 pin lemo split cable or some other configuration. Also wondering if this would eliminate the need to buy/make a traditional BNC to 4 pin lemo sync cable? Any information would be very helpful.
  14. Antennas for receivers and transmitter?

    Hi everyone Here in the UK, we use for some wireless headphones and receivers a frequency between 864-865Mhz as it is free of licence. As this frequency falls in the rage of wide-band antennas, i was wondering if i could plug my ifb transmitter to the antenna out on my venue receiver and use my 2 shark fin antennas with it at the same time as using the venue? Will it work or will it make some interference from one system to the other? Thanks
  15. controlling TRX 900LT from Nomad

    I'm trying to control the gain of a trx900LT from my Nomad. Not seeing anything in the manual that I might be doing wrong... Nomad and TRX are set to 2404, group 1. Nomad IFB mode is TX. The TRX is displaying "Rx" flag, also, "Jam" and "jammed", but the timecode is not what I see on Nomad (which is set to display and output generated TC). Any ideas what I could check for?
  16. good ifb solutions out there?

    for an upcoming gig i need 3 what do you use and why do you like/dislike it ? thanks for any opinion
  17. 744t with zaxcom IFB and wireless

    Hey guys, I was talking to this production coordinator I'm doing 2nd unit with and he mentioned that the production wanted me to switch to zaxcom wireless. There reasoning is so they can run off and still have good tracks. I've used the whole zax system before (fusion, IFB, & wireless) and it worked for the most part. I wanted to know if I used my 744 instead of a zaxcom recorder would the zaxcom IFB still send the commands to record and stop recording to the zaxcom transceivers? Has anyone tried this? Keenan
  18. 788t output routing

    I discovered a great feature of the 788t when I was testing an ifb today. I have one of my outputs for my utility PL routed to x2 mix with all inputs including mine set on postfade. I was playing back the L mix track and not hearing anything in the ifb. I realized that if I want video village to only hear the live mix, and nor hear the playback, all I need to do is re-route the output going to the comtek xmitter to an output (like x1) . This is very useful if you have to review your tracks regularly. Just FYI
  19. 552 mic mono out to TA5 LMa for IFB

    I want to upgrade g3 to LMa R1a combo. I have difficult time finding info on 3.5 to TA5 cable. I would have contacted Lectro and/or Sound Devices, but believe this is a question to an end user.
