  14. Subject: DC offset
  15.  
  16. Our HPs 735s, with the 4231 chip, have the same problem, constant DC
  17. offset that is some function of the gain setting.  Analog Devices
  18. aknowledged that their counterparts have this problem.  I've not
  19. contacted Crystal for confirmation that it is a CODEC problem, but it
  20. sure seems that way.
  21.  
  22.  I'm not sure about the drift.  On the Analog Devices 1848, it was
  23. constant, I've not done enough with the 4231 to know.  If you are seeing
  24. drift to a null offset, when do you get the null offset?  Whenever you
  25. change gain?  I may be able to live with this.  That is, if I can set
  26. the gain and at some point in the near future have no offset.
