There will only be one individual working that sector (NE satellite, 126.97). Hartsfield does have dedicated arrival/departure controllers and sectors, but to the best of my knowledge, the sectors covering all of the airports around Atlanta do not have any dedicated departure positions. Many of the turbojet aircraft departing PDK, FTY, RYY, MGE, etc., will often be handed off to the departure sector(s) for ATL, but they still talk to the appropriate satellite controller first.
