Radial J48 Premium Active DI

Phantom Powered Active Direct Box. 

The J48™ is an active direct box that has been optimized to handle extreme transients without distortion, with a linear frequency response that extends from 20Hz up to 40kHz.

Features:

• Exceptional headroom & dynamic range
• Retains the natural sound of the instrument
• Merge switch sums stereo instruments to mono
• Powered by 48V phantom, no batteries required
• 15dB Pad: reduces the input sensitivity for active basses and high output keyboards.
• 48V Check: flashes once when the 80Hz filter is depressed to confirm 48V phantom power is present.
• Merge: changes the input and thru-put to two LR inputs and mixes the output to mono at the XLR.
• Input: instrument input connection to the J48.
• Thru: throughput from the J48 to the amp. Hi impedance will not load instrument down.
