Radial’s Shotgun stereo amp driver/distro can drive up to four amps without introducing ground-loop interference. Each output is buffered to lower impedance and allow the player drive the signal longer distances onstage. Output 1 provides a ground path to the guitar while Outs 2, 3, and 4 are transformer-isolated to eliminate ground-loop hum typical in multi-amp setups. Each out also has a ground-lift switch. When used dual as a 1×2 splitter, its Constant Load Correction (CLC) circuit ensures impedance remains consistent. It uses a standard 9-volt power supply or connection to a power brick, and its top-mounted polarity-reverse switches ensure all amps play in-phase.
