This is a well-documented problem in the Orion II that has to do with a
different attenuator/chip scheme between the speaker circuit and headphone
circuit. It's not impedance related, although large deviations from 32 Ohms
or using low-sensitivity headphones will make the problem worse. The newest
firmware version, 2.041XT brings the two levels closer together when used
with the 'IF AGC' setting.

Subject: [TenTec] Head-Phone volume in Orion2
I have the (perceived) problem that the volume from my head-set
headphones is much lower than the equivalent speaker volume. I'm using a
Danmike head-set (32 Ohm, 97dB @ 1mW (IEC 318))
Is there any way to adjust the relative output volume between the
speaker and head phone outputs?
