NexGen: Audio Panels Ins and Outs

This is not the post that I started to write. But I can't help myself.

Fig 1. - Commercial Aircraft Audio Panel

The Problem: You just bought a new Gables audio panel for your flight simulator from eBay, but you don't know anything about the panel, so before you do any kind of problem solving you grab your trusty simpers and start cutting.. ie.. It time for that rewire.. right?

Wrong.. You should have done a little investigation, made a few calls maybe even to Gables... Hey they have always been helpful with a pin-out diagram.  You just have to ask nice. That would have solved the problem of the the two connectors at the rear of the unit. ( See Fig 2.)

Bendix Connectors

They are just standard Bendix type connectors that are very well understood.

I am an engineer and you never want to reinvent the wheel!


If you play fast and loose with your cutters then you will end up with this: (See Fig 3.)

 

But with just a little bit of work you could have ended up like this (image below) Now doesn't this look much better with a whole less work! Just remember that this is for one channel, my ACP is taking its inputs from my RSS or Radio Sub System. In the aircraft you have a 'remote electronics unit' which is a distribution amplifier for 12 radios. Remember a pilot my have 4 or 5 radios in his ear, but can only talk on one radio at a time.

    Hi Chris,

     

    Nice update.  An yes, REUSE REUSE REUSE is always a good engineers stock and trade.

     

    Reminds me of one of my early jobs tracing down connectors for some missiles for a test stand.

    We had to comb through the documents to find the pin outs and define the voltages needed to activate the electronics without setting them off.

     

    It always pays to double check the pins and verify block numbers.
