The invention relates to a high-frequency system for an MR apparatus with a high-frequency coil arrangement comprising a plurality of resonator elements (), which is connected to a transmit unit (), where a respective transmit channel (1&#x2013;8) of the transmit unit () is assigned to the resonator elements (). In order to provide a high-frequency system of this kind at low cost, by means of which a high frequency field can be generated in an examination volume () with a field distribution that can be preselected flexibly and variably, the invention proposes that the transmit unit () is equipped with a plurality of high-frequency amplifiers (), the inputs of which can receive low-power transmit signals via a first controllable multiplexer/distributor network (), in which the output signals of the high-frequency amplifiers () can be distributed over the transmit channels () via a second controllable multiplexer/distributor network (). In addition, the invention relates to an MR apparatus with a high-frequency system of this kind.
