BBC high impedance headphones.
Hi could any one please tell me if high impedance magnetic headphones are wired in series or parallel? They are 2000 ohms each ear.
Thanks Mick. |

Re: BBC high impedance headphones.
If you're asking how they're wired, check with a meter across the lead or plug.
If you're asking how they should be wired, presumably for use with a crystal set, the answer is in series.

Re: BBC high impedance headphones.
You'll probably find that the harness is permanently wired in series.
