The Rossi X-ray Timing Explorer made a short (10 ks) observation of the radio galaxy Centaurus A on 14 August 1996. Analysis of the combined 2.5-240 keV spectrum has revealed the presence of a broad iron emission line and yields an upper limit to a Compton reflection component significantly below values for radio quiet Seyferts. This is in addition to a heavily absorbed primary power law extending beyond 200 keV, plus an identical unabsorbed power law at about 6% of the intensity of the primary flux in this short observation. The implications of these components will be discussed in context of the radio quiet/radio loud dichotomy.
