You side with the crazy hillbilly?!!!!!

Tsk, tsk, tsk. Just more self-serving name-calling, and still we see no quantitative data supporting your less than tenuous grasp of the technical issues, while all the while blustering authority.

Then, looking at your posting record reveals that you're more interested in quantity than you are in quality and that your goal seems to be to post as many articles as possible in order to up your "score", regardless of the worth of the content of your posts.

YYWE - if you say so..............

 

So, if one were to endeavor to make a custom output transformer and knew the output impedance of the intercom panel is 600ohm, what would the high side of the transformer be? The load side of the transformer would be 16ohm, to match a common stereo headset.

And the last question would be, since it's "reflective" from the load back to the input side, is it better for the input side (the xxx : 16ohm) to be the same, greater, or less than the intercom panel output?

It's amazing how many articles and papers exist on this subject but fails to really get into specifics like that.

 

With any decent amplifier if the load impedance is close to or above its rated output impedance things are generally not a problem. 2:1 over impedance is not really an issue other than having a slightly less than optimal per transfer capacity which as you have found out means having to turn up the volume a bit to compensate for it.

I for one have abused amplifiers of all designs all my life and never had any major issues with running something with a higher than nominal load impedance.

Lower than rated impedance loads while running at the upper end of the amplifiers output capacity is where you run into problems.

So if I'm attempting a transformer--a custom-- what would the high end need to be if the load is gonna be 16 and the source ohms are 600?

I wish I had the output voltage.

If you making a custom unit then aim for 600:16 +-10% and be done with it.

Personally, if it was me and nothing is giving problems I would just live with it as is.

 

That's why Ian is on my Ignore list. I only peeked this time because I have a dog in this fight.

As I have learned the hard way, don't turn off your ignore list. You will always regret it later, guaranteed.

How many are you on?

 

How many are you on?

How should I know.

If I am on any it's obviously no one's that matters enough to me to be aware of it.

Pretty much same here.
