Operation

• Give D2 ten minutes to warm up and attain an internal thermal
   equilibrium, which ensures a seamless flow of enchanting music.

• Switch the one-second buffer on for music and off for video. 

• Turn off the up-sampling feature of your player and play music at its 
  original sampling rate. D2's dedicated DSP with COS Engineering's  
  algorithms will do a the job.

• Fix the volume of your player at its maximum and use D2 to adjust 
  volume. Failing to do so may reduce the bit-depth of music data and 
   compromise musicality.
