 |
|
Here is what I am learning on this subject:
<![if !supportLists]>1) <![endif]>My current Telex 50D headsets run on 8 – 28 vdc. Changing the cord / plugs will void the warranty.
<![if !supportLists]>2) <![endif]>The ANR headsets in my Flightsuits helmet are supplied by Headsets Inc. and run on 9 vdc.
<![if !supportLists]>3) <![endif]>The plug / connector that Headsets Inc. uses are Switchraft numbers 760 and 712A.
<![if !supportLists]>4) <![endif]>There does not seem to be any movement towards a single connector standard. The person at Telex indicated that their unit in this configuration was extremely low volume and there was no interest in putting any effort into improving it or talking with anyone about standardizing.
<![if !supportLists]>5) <![endif]>I flew again yesterday using my wife’s Bose headset and the ear cups don’t fit my (big??) ears that well. I don’t want to convert back to Bose for myself (she continues to like them a lot).
<![if !supportLists]>6) <![endif]>This is what I am going to do:
<![if !supportLists]>a. <![endif]>Install Headsets Inc. 9 vdc converter / power connector in the front seat of our Decathlon and both seats of the Rocket.
<![if !supportLists]>b. <![endif]>Find a source to custom make very nice 3-plug cables; standard mic, standard headset, and the 760 power plugs. I’m looking for gold plated plug contacts, molded plug bodies, and a nicely molded 3-way “Y” where the 3 breakout. I’ll buy a few of these and retrofit them to whatever I like.
<![if !supportLists]>c. <![endif]>Retrofit this new cable to my Telex headsets (voiding the warranty).
<![if !supportLists]>d. <![endif]>Retrofit this new cable to my helmet.
<![if !supportLists]>e. <![endif]>Keep a couple of extra of these cables for future use.
<![if !supportLists]>f. <![endif]>Headsets Inc. makes an auxiliary 9 vdc Battery Pack. I’ll use this whenever I want to use any of “my” headsets in another aircraft.
This is the most elegant solution I’ve been able to come up with ……. And I’m open to suggestions.
