The headphone amplifier in the K3 is designed to drive 32-ohm headphones. It can drive higher and lower impedances, but the audio level will be less. We put 8.2 ohm series resistors at the front jack and again at the rear jack so plugging in a shorted plug wouldn't kill the audio on the other jack. As a result, lower impedance phones will have less drive available. The headphones are *not* attached to the output of the speaker amplifier. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
