[TenTec] Using a Yamaha CM500 headset with TT Orion II - advice, needed! (Steve Ireland)

[Floyd Sense]

I've used the Yamaha CM500 for a couple of years now with my Orion II.  
I use the bias at the level provided by the Orion.  H/W Mic Gain is set 
to 0.0 dB and a mic gain setting of 13 works just fine. Never had any 
distortion.  I believe I used a 10 mfd cap in series with the audio to 
the Orion.
