“While less expensive DI's are easy to find, this one has proven it's worth to me - I intend to buy a couple of them for my studio.”    ~ Dave Martin, Audio Media magazine

Radial J48 Active Direct Box

  Active 48-Volt phantom powered direct box
  Minimal power draw with high rail voltage
  Will not choke when driven hard
  Low inter-modulation distortion

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, 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 J48 is built to handle the abuse on the road and features a unique welded I-beam construction for years of trouble free performance.







Optional J-Rak rack-mount addaptor:

The J-Rack is a unique direct box shelf and 19” rack adaptor that allows up to 8 J48 or JDI direct boxes to be rack-mounted in 2 rack spaces. This unique adaptor allows improved inventory management for sound companies allowing DI inventory to be used as stand-alone or rack mount depending on tour needs. The J-Rak is shown here with 4 JDI's and 4 48's, 2 of each are mounted with inputs facing front and 2 of each with outputs facing front.
