A cross-shaped diffusive system with two superconducting and two normalelectrodes is considered. A voltage $eV < \Delta$ is applied between the normalleads. Even in the absence of average current through the superconductingelectrodes their presence increases the shot noise at the normal electrodes anddoubles it in the case of a strong coupling to the superconductors. Thenonequilibrium noise at the superconducting electrodes remains finite even inthe case of a vanishingly small transport current due to the absence of energytransfer into the superconductors. This noise is suppressed byelectron-electron scattering at sufficiently high voltages.Comment: 4 pages, RevTeX, 2 eps figure
