Constantin Posted August 9, 2016 Report Share Posted August 9, 2016 I'm using it on my current show to transmit audio and timecode to cameras and haven't had a single drop out in audio according to camera operators Very interesting! So are they wearing headphones? Quote Link to comment Share on other sites More sharing options...

Yes, it's a reality show, and they like to wear ear buds to follow story. But some times they just don't care so you see earbuds hanging off their shoulders. ;-) haha Quote Link to comment Share on other sites More sharing options...

Tony Johnson Posted August 9, 2016 Report Share Posted August 9, 2016 14 hours ago, Jose Frias said: Correct, active amp. It has a DC jack on one of the sides, and I have a power cable wired to hirose to power off of my Audioroot distro. It's very low power draw, about 100mA. It's a 1W amp, OEM by Sunhans for Sound Guys Solutions, but specially tuned and filtered to work with Zaxnet. I have done some very unscientific tests, and have found there to be 25-50% range increase overall with just a rubber duckie straight on the amp. More impressive though is the better reception through walls and other hard surfaces. I'm using it on my current show to transmit audio and timecode to cameras and haven't had a single drop out in audio according to camera operators, even with some of them being in other rooms or areas, though I haven't been over 50 feet away from them either. I would imagine that a different / directional antenna would maybe provide increased range towards a specific direction, but on this show cameras can be in any direction so probably not ideal for me right now. I remember seeing Sam Kashefi post a small directional antenna not long ago, it looked good. This is such good news and I am sure it will be great on carts too with an L-Com antenna. The DC power draw will be way more elegant than what I currently have. All in all a winner without even trying it. When can we expect to lay our hands on these?

John Blankenship Posted August 10, 2016 Report Share Posted August 10, 2016 100ma x 12v = 1.2 watts of power dissipation and would radiate the same amount of heat as a 1.2w light bulb. However, how that 1.2w is dissipated via the chassis would affect how it feels to the touch at any given point. Remember, Ohm's Law is for your protection! Support your local Electromotive Force.

Ze Frias Posted August 11, 2016 Report Share Posted August 11, 2016 Also, here's a photo that Kashefi posted on the Facebook Zaxcom group regarding his directional Alfa 7dBi antenna: Below is the link: https://www.amazon.com/dp/B003ZWPRUI?psc=1 This antenna will not work directly into the zaxnet connection on the Nomad as it is reverse polarity. You'll need an adapter (or this amp) to make it work. Quote Link to comment Share on other sites More sharing options...

Jeff Wexler Posted August 11, 2016 Report Share Posted August 11, 2016 2 hours ago, MartinTheMixer said: If you guys (and girls) could weigh in. What is it about the heat that has you concerned? I think generally the concern with heat, with any component of our gear, is that heat is an enemy and can often lead to shortened life, reduced performance and failure. Almost every electronic device we use produces heat and each manufacturer has to figure out the best ways to dissipate the heat (heat being a necessary and expected by product of the components and processing in use). There have been times in the past where the manufacturer has not figured out how to deal with heat --- the first StellaDAT got so hot that it would just shut down altogether, making it basically unusable on many jobs. Several of the RED Cameras, unable to deal with their own heat production, have had similar problems. So, bottom line, heat is always something to be concerned with until a piece of gear proves itself to be reliable and not subject to failure.

I have taken devices apart before and been really surprised about how pitiful a job the maker has been at heat sinking. I switched from one mixer/recorder to a different one, and the heat went way down, along with wattage usage. Until I switched to the more efficient mixer/recorder, I was considering a huge heat sink attached to the top of the device. I had already inquired with the manufacturer about doing this, because I was concerned about sending all that heat in one direction. That last sentence is poorly worded, but I will leave it there. The manufacturer indicated this would not lead to new problems, but I changed devices, so I did not make the mod. Quote Link to comment Share on other sites More sharing options...
