Radial’s J48 active DI is the choice of engineers around the world! The J48’s unique phantom powered DC-to-DC transformer isolated switching power supply provides amazing headroom while eliminating ground loops, hum and buzz. The Jensen® transformer-equipped JDI from Radial handles high-output, active instruments with a musicality that audio engineers love! The welded I-beam construction insures that this direct box will stand the abuse the road can throw at it.
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, 180° 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. - Active 48-Volt phantom powered direct box
