Radial J48 Active 48-Volt Phantom Powered DI Box
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.
