The Radial J48 has gained a tremendous following through the professional audio community. With significantly more headroom, lower distortion and unmatched durability, it is no wonder that the J48 has become the most specified direct box on stages around the world and there is no doubt that the J48 Stereo will follow suit. As you will note, the J48 Stereo is exceptionally linear with a frequency response that exceeds 40kHz. Just as impressive, it produces a wonderful cascade of even order harmonics reminiscent of the finest studio equipment. Amazing signal handling, great sound and low noise… The J48 Stereo rules!
