Narrative:

We were on vectors for atl runway 28 ILS. We had been set up for ILS runway 27L. I; as the PF and co-pilot; made the changes in set-up but failed to notice I hadn't set the proper front-course for runway 27L and didn't reset it for runway 28. When we were given a heading to intercept the localizer runway 28; I also noticed for the first time we were cleared for an ILS prm approach. We hadn't set in the monitor frequency. As I start to put in the frequency we flew through the runway 28 localizer. I noticed this in fairly short order and immediately and aggressively turned back to centerline but by then we had come to the attention of the controller who gave us instructions to descend and back to centerline. We continued the approach for an uneventful landing.

Narrative: WE WERE ON VECTORS FOR ATL RWY 28 ILS. WE HAD BEEN SET UP FOR ILS RWY 27L. I; AS THE PF AND CO-PLT; MADE THE CHANGES IN SET-UP BUT FAILED TO NOTICE I HADN'T SET THE PROPER FRONT-COURSE FOR RWY 27L AND DIDN'T RESET IT FOR RWY 28. WHEN WE WERE GIVEN A HDG TO INTERCEPT THE LOC RWY 28; I ALSO NOTICED FOR THE FIRST TIME WE WERE CLRED FOR AN ILS PRM APCH. WE HADN'T SET IN THE MONITOR FREQ. AS I START TO PUT IN THE FREQUENCY WE FLEW THROUGH THE RWY 28 LOC. I NOTICED THIS IN FAIRLY SHORT ORDER AND IMMEDIATELY AND AGGRESSIVELY TURNED BACK TO CTRLINE BUT BY THEN WE HAD COME TO THE ATTENTION OF THE CTLR WHO GAVE US INSTRUCTIONS TO DESCEND AND BACK TO CTRLINE.
