Samson S-direct plus is a stereo active direct box designed for keyboards and other instruments with multiple outputs. It provides two linked 1/4-inch input/output paths and gold-plated XLR balanced outputs for long cable runs. Powered by 48 V phantom power or 9 V battery with auto shut-off, it includes a switchable ground lift and a rugged aluminum chassis. The unit delivers consistent frequency response and strong common‑mode rejection for clean, direct signal routing.
