Abstract	A four-detector perturbed angular \gamma\gamma-correlations (PAC) spectrometer for condensed matter study is described. The timing resolution (full-width at half-maximum) is 200 ps for ^{60}Co if BaF_2 scintillators coupled to photomultiplier XP2020Q are used. The spectrometer is equipped with a press; a specially-designed pressure vessel permits one to perform PAC-studies of samples under pressure up to 60 GPa in the on-line mode. In contrast to the common case (usage of single-channel analyzers) the software-controlled energy selection makes the spectrometer easy to use, to control and to adjust.
