My Orion 1 has the same problem reported in the original posting. I have to
run the AF gain at about 75% when driving my Heil ProSet, and unplugging the
earphones causes the internal speaker to really blast since it only requires
about 30% AF gain to drive it fully. I'd also like a solution without
losing the Heil ProSet, which I really like.

Does anyone have a method that matches the output of the Orion 2 to the
Heil Pro set earphones. I believe the O2 has a 600 ohm output and the
headset is 8 ohms. I tried using two of radio shack 1000ohm to 8 ohm
audio transformers, but that didn't seem to work, unless I did something
wrong. I used two to try to use the stereo feature of the O2. I have
the rf mod in also.
I don't like unplugging the earphones and having the audio blast into
the room when I forget to turn down the audio gain.
Any help would be appreciated.

The headphone output of the Orion II is 16-32 ohms. I have two Heil
Pro-Sets, a Heil BM-10 and a Heil Quietphone. They all work fine directly
plugged
into the front panel headphone jack.
