More headroom. And more dynamic range. The J48 Stereo is the perfect companion for your guitars, basses, and high output line level instruments. Unlike typical active DI boxes, the J48 Stereo won’t overload when you play at maximum volume. Thanks to its unique switching power supply, the internal rail voltage can be raised to handle up to 9 volts. That means improved signal handling for virtually noise-free operation. You’ll get natural tone and character, every single time.
