Good morning, first time posting.
Still trying to get a good education on the subject matter, so forgive me if questions are presented properly.
--I have an aircraft intercom that puts out an audio signal with 600ohms. I do not have the power information for it--still looking.
--Normal aviation headsets use 300ohm speaker cups (150 when in parallel).
--I have a 1000:8 audio output transformer (found one remaining radio shack #273-1380 in my city) that does the job, but I'm wondering if I should be more specific since the headphones I'm using are standard over-the-counter 16ohm speakers.
--This project is merely to solve the problem of finding FAR more comfortable ear buds and headphones in the consumer market than in the realm of aviation-related products.
I'm having a tough time getting some general output transformer questions answered:
1. Is the 1000:8 a range within which appropriately rated devices can be fit, or a ratio that is applied to whatever is sitting on each end of the transformer?
2. Or, if I use 16ohm speakers does that mean it's effectively 2000 on the upwind side? I ask this because although the sound quality works VERY well, I've had to reposition the volume knob on the panel to a higher setting than where it usually sits.
3. What does the 1000:8 mean when the incoming signal has an output impedance of 600?
4. Should I be looking for a custom transformer with 600:16?
Thanks in advance; I'll be researching in the meantime.
