That link has some weird special characters stuck on the end of it. Not sure 
how that happened. This link works 
https://elecraft-kx.groups.io/g/main/message/9486 and is the link in the 
updated blog post.

Yes, both provide power for active electronics that boost the mic 
element's output and make an impedance transformation (the mic element 
is VERY high Z) to drive the mic preamp (in the case of the unbalanced 
mics used in ham radio), or to drive a long length of cable (for 
balanced pro mics).


The two systems are very different though -- the bias circuitry used for 
unbalanced electret mic elements won't work for balanced pro mics, and 
the "phantom power," a positive DC voltage applied equally to both sides 
of the balanced cable (pins 2 and 3) with negative to the cable shield 
(pin 1) won't work with unbalanced electret elements. Those pro mics 
have a gain stage and low-Z balanced line driver built into them, which 
operates from phantom power.


Indeed, there are unbalanced, capsule-only versions of miniature pro 
mics that are used with wireless mics, using the same unbalanced "bias" 
method we use in ham radio, and the bias is provided by the wireless 
transmitter. This is what you're seeing with clip-on mics worn by on-air 
people, and by musicians with clip-on mics.

Re: [Elecraft] Microphone Setup Confusion

2023-05-16 Thread Walter Underwood

The mic bias is +3.3 V on the tip. On the KX3, there is also a logic level DC 
voltage on the ring. This is not as clean as the mic bias and can cause some 
noise on mics that short those. You can split out those signals with a TRS plug 
or a stereo-to-mono splitter. See this blog post (from me) for details.

https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/

Phantom power for studio mics is quite different.

Bias is a much lower voltage than phantom power.

Is what Elecraft calls mike "bias" in the K3 and K3s Owners handbooks 
Equivalent to the "48 volt ghost voltage" required for condenser mikes et al
In the broadcast and music industry ?

It is mentioned that "mike bias" needs to to be turned on for condenser type
mikes
But off for dynamic types which is also equivalent for the more common 
Term  "48 volt ghost voltage"

No. "Elecraft bias" is a low voltage applied to electret mics.
