The PS-2400 is a high power stereo amplifier which incorporates a rugged 2 unit all-steel chassis ensuring structural rigidity and protecting components. The low-noise fans offer both quiet and cool operation while the high energy toroidal transformer saves weight. The amplifier incorporates rear located switches which permit ground lift, operational mode selection (bridge, stereo or parallel) and input sensitivity selection.
