Like its counterpart, the Digital Stream D2A1D20 is not CESB certified, and therefore is not eligible for use with the $40 government coupon in the United States. It does, however, have all the standard CESB features, and it can output over RF to either channel three or four. The Digital Stream D2A1D20 is no longer officially available for purchase, as it has been succeeded by the Digital Stream DTX9900.
