The results of a preliminary partially quenched (Nf=2) study of the light hadron spectrum, renormalization constants and light quark masses are presented. Numerical simulations are carried out with the LL-SSOR preconditioned Hybrid Monte Carlo with two degenerate dynamical fermions, using the plaquette gauge action and the Wilson quark action at beta = 5.8. Finite volume effects have been investigated employing two lattice volumes: 16³ x 48 and 24³ x 48. Configurations have been generated at four values of the sea quark mass corresponding to MPS/Mᵥ 0.6 - 0.8.
