Phantom Powered Active Direct Box The J48 is a high-performance active direct box for live concert touring and professional recording studio applications, with the ability to handle extreme transients without distortion while delivering the natural sound of your instrument.
Higher Rail Voltage, Higher Headroom Most battery-powered guitars and basses will produce as much as 7 Volts when played at maximum volume, which can easily overload typical active direct boxes that can only handle about 3 Volts. The J48 uses a unique switching power supply that raises the internal rail voltage to handle up to 9 Volts, resulting in improved signal handling and greater headroom. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of the instrument to shine through.
