[SML] Audio from landline phone mic

[mouse at fieldmousepro.com]

Yep, telephone hybrids are still very much in use for the broadcast TV 
world. Getner was one of the more popular brands, and they're often 
called "Getners" as shorthand.

However, they might be overkill for what this situation needs. Since 
there's no requirement to have a 2-way conversation on the telephone 
line, the nulling electronics of the hybrid aren't needed.

An alternative you could try is to simply hook up the microphone wires 
of the phone to your audio console & see if it sounds decent enough for 
your use. If you have an older phone with no electronics, you can 
connect the two phone wires from the normal phone line jack (the center 
two wires of the 4 or 6 pin RJ connector). That way, the handset cradle 
switch will cut off the mic when it's on-hook.

If that doesn't work, or if the phone needs power (48v DC), a simpler 
way is to hook up the wires that come from the handset itself. There 
will be 4 wires on the smaller RJ connector. 2 will go to the mic, and 2 
will go to the speaker. I can't remember the standard pinout, but it 
won't be hard to figure out which is which using a little trial & error. 
You won't hurt anything if you hook up to the speaker instead of the 
mic. Depending on the style of mic on the handset, you might even get 
better audio from the speaker. Just swap the mic & speaker in the 
handset if they're the same size.

Anyway, those are some extra options to consider if you like.
