Barrie" Subject: AeroElectric-List: Pro G hub As typical of many discussions people throw out comments without specific experience with the product. After reviewing many of the posts here are my comments. First, the company was sold a while back and is in the hands of some great people in Minnesota. I purchased mine from the previous owners. I was working on an issue and contacted the new owner (Tim) and he was 100% helpful. The previous people were great too. Everything worked as it should from the first time the power was applied. There were a couple of minor issues encountered that are discussed below. Someone mentioned the weight difference. I think in the overall scheme it may add a little but so does failing to go to the bathroom before flying!!! It will handle ANY system. As far as upgrading, it is as simple as adding the appropriate cable. There may be a chance you would have to send in the hub, but not sure. How many people change out their panel anyway. If you needed to can the who thing, this would be the cheapest thing to replace anyway. You get the complete wiring diagram and specific "pin outs" for each cable. Not being familiar with this aspect of building, I found the diagrams and pinouts easy to read. I mounted the Hub just behind the panel (tip up) on the right side. It is 100% accessible and looks very neat with the cables tied together and running to the avionics. All of the cables have the computer look with sealed connectors at each end. (except the audio panel at the avionics end) I figure I added about $400 to the overall cost of the wiring with the system. The $400 was well worth the reduction of the BS factor on the install. The install is quite simple with biggest issue being the audio panel with lots of loose wires to find their homes. I have the Pro G hub with the following equipment integrated with the hub. Garmin 340 audio panel Garmin 430 GPS Nav/Comm Garmin SL40 Garmin 330 Mode S transponder Garmin 106A CDI Trutrak Digiflight II VSGV auto pilot ACK encoder The only issues I had with the purchase was not know what the full capabilities of the avionics I selected. As an example, I did not know that I needed 4 unswitched audios for various components. The old Approach Systems apparently did not either and didn't wire for these. With the guidance of Approach Systems I was able to pin out a few more wires. Also the Garmin 330 Mode S transponder has Density Altitude capability if wired for a temperature probe. I did not know this. Again I wired a couple of wires and it was done. I spoke with the new owners about this. I recommended that they conference with customers as to their equipment and the capabilities so everything is wired as desired and the full capabilities are experienced. Tim related they would do that. I should also point out that their knowledge of individual pieces of avionics is exceptional. Since they are an avionics shop the knowledge base is excellent. In summary, if you are concerned about your ability to wire your panel, simple or complex, do not hesitate use the Approach Systems product. Despite the nominal extra cost you will reduce your wiring time 10 fold with a system that works as it is supposed to. Sorry for the length but I wanted to clear up some of the misconceptions reported. Darwin N.

This battery pack uses 6 each AA batteries. My dilemma is that I own 2 aircraft (both tandem seating) and several headsets (all ANR) and need to eliminate all battery packs. I have a strong dislike of things flopping around in the cockpit. This dilemma seems to be exasperated by the lack of a standard power voltage and connector to drive the ANR in all headsets. My questions are: 1) What voltage does my 50D headset ANR run on ?? The specs in the Telex website differ from my actual unit in that my unit is using 6 ea AA batteries. The website says this unit runs on 4 each AA batteries. If it is running on 9 volts it will help my situation. I've contacted Telex about this and am waiting for an answer. 2) One of my other ANR Headsets is a helmet with Headsets Inc. ANR system that runs on 9vdc. I spoke with Headsets Inc. and he didn't know what connector he is using for the power - would anyone here know ?? 3) Does anyone have a sense of a "standard" connector configuration emerging ?? 4) I believe the connector configuration I will be choosing will be: a. Standard microphone connector b. Standard headset connector c. Similar style but different sized plug for ANR power - powered at 9 vdc. This would allow each headset with this configuration to be used in any of my aircraft; or any other aircraft with either no ANR or an auxiliary battery pack to power the ANR. Would you please give me feedback on this plan ?? Is it optimal ?? 5) What power connector would anyone here recommend ?? 6) Is there any other source for this magic Power Supply to supply good 9 vdc ?? 7) My wife has the Bose headset - I'm guessing it runs off a different voltage given it uses 2 each AA batteries. What can I do to make it fit into my scheme ?? My design goals are: A) Inter-compatibility (or as much as possible) between my headsets and my aircraft. B) No battery packs in my 2 aircraft C) Ability to allow anyone else with standard headsets to plug into my aircraft (with or without their own ANR). D) Ability to use my headsets in other aircraft not equipped with my ANR Power plugs - using an auxiliary battery pack of my own. E) Keep all of my headset cords short with connectors located near my shoulders (I have done this before and it works very well).

The female receptacle pins are protected by being internal in the "male" shell. So both are mechanically shielded by their shells. Hope this helps.

I made up small connector panels for each of the headset positions, placed them close to the shoulders as you described, and ran a twisted pair to each. The twisted pairs all come back to an LM317 based power regulator set to provide 9V. Any headsets I purchase will be 9V compatible. I can add the miniDIN connector if it isn't there already. 4 AAs will be 6V I believe, and 2 AAs will be 3V. 1.5V for each cell. But they may be wired in parallel within the battery pack, instead of in series. Series configuration multiplies the voltage. Parallel configuration multiplies the (capability to supply) current. It's not save to assume. It would be relatively easy to set up the LM317 to switch between regulating resistors, but you stand a STRONG chance of ruining a very expensive piece of headset gear. If you must have varied types of headsets, the real solution is to have construct a regulator for each, put it in a tiny box that stays attached to the ANR power cord and will then interface with ships power. You can set each headset to what it expects.

Works great but you need a battery pack for other ANR headsets. If I did it again I would just install Bose connectors and make up some short pigtails with a Bose male on one end and standard headphone sockets on the other. You could add a power connector to the pigtail for other ANR headsets. To deal with the stereo/mono issue I used stereo headphone jacks with a few hundred ohm resistor in series with left and right to allow use of mono or stereo headphones. IIRC this was suggested by the intercom manufacturer.

Yes that is what&n bsp;I do.
In addition though I always a rrange that the male shell (plastic

________________________________ Message 14 ____________________________________ Time: 04:28:59 PM PST US From: Ralph Hoover Subject: AeroElectric-List: ANR Headset Power without batteries Larry, I just received Jacks for my Headsets Inc. install from Mouser. If you wish to isolate the ground you will also need .312 I.D. Shoulder washers. I didn't order any and had to machine a pair!! www.mouser.com ----------------------------------------------------------------- ORDERED STOCK NUMBER SHIPPED PRICE EXTENDED ----------------------------------------------------------------- 2 502-L722A 2 4.290 8.58 Switchcraft L722A DC Jacks PWR JCK LNG BSHG "2) One of my other ANR Headsets is a helmet with Headsets Inc. ANR system that runs on 9vdc. I spoke with Headsets Inc. and he didnt know what connector he is using for the power would anyone here know ??" -- Ralph C. Hoover RV7A hooverra at verizon dot net ________________________________ Message 15 ____________________________________ Time: 07:40:48 PM PST US From: Ralph Hoover Subject: AeroElectric-List: ANR Headset Power without batteries Carl, The jury is still out,I have not flown with the ANR conversion yet. When I first turned them on in the shop the fan the was running disappeared. It seems like they will work just fine. Headsets Inc recommends there power adaptor, I believe I will brew my own although I am planning on using a switching regulator. The converter they supply is ground isolated and that is what I plan on replicating. The converter I selected is on backorder until the end of April :( . The audio and dc power share grounds so there is a chance of introducing noise into the system using a LM317 locally at the jacks. I may try the LM317, it sure is a lot simpler and cheaper (LM317's) live in my junk box! The actual installation of the ANR modules was straightforward, the hardware is well done. I replaced the cable with the optional cable that they offer as I don't like the idea of the power cable zip tied to the audio cable. -- Ralph C.

Likewise I would go with a single cord - otherwise looks a bit 'amateurish', and going DC Mono H10-13.4 to stereo ANR is attractive.
