The Radial J48 MK2 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 Radial J48 MK2 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 of the Radial J48 MK2 include a -15dB pad, 180º 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 Radial J48 MK2 is built to handle the abuse on the road and features a unique welded I-beam construction for years of trouble free performance. The main features of the Radial J48 MK2: Active 48-Volt phantom powered direct box Minimal power draw with high rail voltage Will not choke when driven hard Low inter-modulation distortion
