    The Radial J48 is a great sounding active direct box that has been optimized to produce maximum headroom while working within the limited current available from standard 48V phantom power. By employing a unique switching power supply, the J48 is capable of peak transients to 9 volts without choking. The result is lower harmonic distortion, half the inter-modulation distortion and significantly improved dynamics over other DIs.

    Features include a -15dB pad, 180degree polarity reverse, a unique merge function to mix two signals to mono, an 80Hz high-pass rumble filter, and ground lift. Like all Radial products, the J48 is built to handle the abuse on the road and features a unique welded I-beam construction for years of trouble free performance.

        Comments about RADIAL ENGINEERING Radial J48 Active 48V Phantom Powered Direct Box w/Digital Switching Supply:

        I use it to connect a Bass and Bass Amp to a audio mixer for live shows. I don't have to worry about batteries (like the one I use before this)because of the phantom power.
