osa Posted May 23, 2015 Report Share Posted May 23, 2015 thought i might share this for others out there in the same boat. i was in a search of alternative fuels for my qrx 235 camera link. when not D-tapping, i am typically using sony style slim batts like the ones used on SRA/SRB's that give about 3 hour usage or less on a qrx with an iKan 12v regulated sled. with the sony's being discontinued i wanted to find an alternative since my chinese versions are failing left and right. i know others out there use the lithium packs for approx 6 hours use but i was a bit scared by the disclaimers of "do not charge unattended" or "do not charge anywhere near stuff you dont want to burn down". this sort of goes against keeping things super compact but i tried an experiment today with 6x black eneloop pro's in series and a voltage regulator. in keeping the voltage regulated at 12 volts i was able to get just shy of 4 hours of continuous run time on my qrx235. i felt this was a successful alternative to some of the other options out there. my goal is to make a 6-pack aa battery holder to velcro to a qrx and keep as slim as possible. seems like a decent alternative power source since i am using these black eneloops for talent tx etc and i feel the power these give is substantial enough to be quite dependable. this of course is just to hold over until the rx200 launches and then i hope to be able to get one and use the two together with erx's in multi camera setups with the same batteries. just thought i would share. will post pics soon when my setup is complete in case anyone is interested. -Ken Quote Link to comment Share on other sites More sharing options...
Ze Frias Posted May 23, 2015 Report Share Posted May 23, 2015 IMO, if the battery solution cannot holds the receiver for at least 6 hours (or until lunch break), it's not the right solution for me. I just don't want there to be one more thing for me to have to think of while in the middle of everything. I especially don't want the possibility of a scenario where the receiver battery dies in the middle of a take, and that audio is lost. I, too, patiently await for the RX200 to become available, mostly because of its small size and that it also delivers timecode, but I'm concerned about the internal battery life I was initially told at NAB (~4 hrs). If that is the case, I will forgo internal batteries and just come up with a custom external battery solution. Quote Link to comment Share on other sites More sharing options...

Well just a bit of a post NAB update - recent tests with the RX200 are showing internal NiMH batteries will yield in the area of 8 hours of run time and way more if you use power save. Lithium batteries will be in the ballpark of 10 hours without power save. Quote Link to comment Share on other sites More sharing options...

Derek H Posted May 23, 2015 Report Share Posted May 23, 2015 Friendly suggestion to Zaxcom.. Make the sides smooth so it will fit in a BEC box. The NAB demo had a big knob on the side that would make that impossible. Quote Link to comment Share on other sites More sharing options...

johnpaul215 Posted May 23, 2015 Report Share Posted May 23, 2015 ~8 hours battery life is awesome! very happy to hear that. Quote Link to comment Share on other sites More sharing options...
pindrop Posted May 23, 2015 Report Share Posted May 23, 2015 Yes all clear now thanks. The QRX does indeed have 4 channel ENG receiver printed on it, I'd forgotten that, so it's entirely logical, if a little specialized in the context of radio mics use of channels?

Derek H Posted May 23, 2015 Report Share Posted May 23, 2015 It's really a dual receiver, in the same way the Lectro SR is. The only way it can receive 4 audio "channels" is by tuning in two transmitters both of which are in stereo mode. And how often is anyone who owns one actually using it that way? People have been confused about this from day one of the QRX100 I think.. So, the new RX200 is much more like a Lectro 401 or their new LR compact single channel receiver. Of course, being a Zaxcom wireless it can receive a stereo transmission.. Quote Link to comment Share on other sites More sharing options...

Not often, but just a few short hours from now I plan to simultaneously receive both a stereo and a mono signal on one of them at the world's largest single day sporting event.

I did this on a show last year. I had my mixer feed 1&2, and the host's mic always going to CH3.... Just in case. Took a little tweaking to make the frequencies work, and not ideal, but it was ok. I did it because I joined a show that previously had no mixer and the host had what was usually the only lav directly feeding the A camera. They would pop off the cuff things as we were "done shooting" and walking back to the van. After missing a few of those, I worked this out.

JWL Posted May 10, 2016 Report Share Posted May 10, 2016 What is the IFB audio range like for the QRX235 compared to the IFB100 for directors (who have erx's). The specs say the ifb 100 has 75mw power and the QRX235 has 50 mw, But how are people finding the difference out in the field? Quote Link to comment Share on other sites More sharing options...
