You should connect the L/MONO Unbalanced 1/4" output of the HD300 to your power amp's 1/4" Channel 1 input.
The "Master Volume" trim pot knob (to the left of the L/MONO jack) will be the output volume control knob for the HD300's signal, so make sure you adjust that accordingly. Also, the UNBALANCED OUTPUT switch should be set to "Line".
The trim knob will need to be turned up; if it's all the way off, there will be no sound to the power amp. Double-check the integrity of your 1/4" cables, too.
Verify that the power amp works by connecting a different audio device output into it, if necessary (like a CD player or mp3 player).
