Phantom Powered Active Direct Box
The J48™ is an active direct box that has been optimized to handle extreme transients without distortion, with a linear frequency response that extends from 20Hz up to 40kHz.
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 which have are only able to handle about 3 Volts. The J48 uses a unique switching power supply that raises the internal rail voltage so it can handle up to an incredible 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.
