A modified HYPERON spectrometric complex for studying K-meson decays i
s described. The momentum resolution of the magnetic spectrometers and
energy and the coordinate resolutions of the shower hodoscope detecto
rs in the facility are given. The complex reliably identifies beam par
ticles and measures the kinematic parameters of the beam and secondary
particles, including gamma quanta. The experiments were performed at
the JINR Laboratory of Nuclear Problems.
