Headsets Inc ANR Upgrade |
| | 
|
|
| Start looking at the ANR upgrades, the starting donor headset. Mono 13.4 DCs - very comfortable, but no ANR. | 
|
| Gel ear pads removed, inserts out, foam support out. That leaves a couple of screws holding the speaker assembly. | 
|
| The DC speakers are all screw terminals. | 
|
| The mic boom / ear cup. | 
|
| The AL clips used to prevent the cable pulling out required cutters and were tougher than I expected. | 
|
| The new ANR parts - pink confa for, dual speaker module and felt cover. | 
|
| All the parts laid out. | 
|
| The RHS speaker assembly with top band cable. | 
|
|
| More soldering / joining the vaious parts - pretty simple just follow the instructions. | 
|
| Close up of the main module, ground, power and signal goes to each side, the mic is just connected directly as before. | 
|
| Then cram the pink foam in and use the double sided tape to keep the modules in. | 
|
| Everything back together and cable guides re-installed. | 
|
| The resulting headset (with battery box) | 
|
|
| During the flying down south I had some problems with the mono position on the new ANR modules. Did some digging and found a couple of try solder joints in the switch unit. Simple once I found it. |
