The gain can be set by means of two identical DIP switches
located on the bottom side of the unit, one for the right
channel and one for the left channel. For a correct stereo
image both switches must be set to the same position.

The gain setting is optimal if, upon reaching the desired maximum volume,
there is still a little reserve for readjustments. For use as preamp, the +0 dB
gain setting will be just right in most cases. The following table contains some
recommended gain settings for various headphone models.

Gain settings for various headphone models
The suggested gain settings in the table below are merely approximate values
and depend on personal listening habits and also on the sensitivity of the differ-
ent headphone types. Start by selecting the lower gain setting. Only switch to a
higher gain setting if you get to the right-hand stop of the control quite often
without achieving your desired maximum volume level.
