Radial J48 1-channel Active 48v Phantom Power Direct Box
Features:
• Minimal power draw with high rail voltage.
• Will not choke when driven hard.
• Low inter-modulation distortion.
• Innovative merge function.
• Welded I-beam construction makes it impossible to torque the PC board. This virtually eliminates cold solder joints - the No.1 cause of system failure in the field.
• An innovative 'slide-in-place' XLR trace makes it possible to use I-Beam girder construction.
• A digital switching power supply steps-up the internal rail voltage to 9-Volts. The J48 will not choke like other DI's when hit with large transients.
• A military-grade PC board is employed for maximum wear and tear in abusive environments. Welded steel standoffs ensure the PC board will not shift.
• A -15dB pad allows super hot inputs such as that from a CD player to be connected and balanced for long runs.
• Momentary 48V Check LED will flash once when the 80Hz filter is depressed to tell you phantom power is present.
• The Merge function turns the input & thru into 'left & right' inputs to mono mix at the XLR output. This handy function saves valuable inputs on the mixer.
• The input is connected to the instrument.
• The thru-put is connected to the instrument amplifier. The J48 has a high input impedance to reduce loading.
• Our book-end design creates a protective zone around the switches & connectors for best protection.
• A heavy-duty baked enamel finish for excellent durability and great looks for years. 100% 14-gauge steel construction.
• The 600 Ohm balanced XLR out is mic level to properly match concert splitters - will drive 1000 feet without appreciable noise.
• A polarity reverse switch flips the polarity from the AES standard Pin-2 to Pin-3 on the XLR and is used when combining sounds that may be out of phase.
• An 80Hz low-cut (highpass) filter gently reduces excessive bass for more headroom and clarity. Eliminates run-away resonant feedback from acoustics.
• The ground-lift disconnects the ground path to the transformer at the XLR output. This is used when a ground path is made at the input side such as with a keyboard.
• A no-slip full bottom pad reduces mechanical vibration, improves electrical isolation and keeps the J48 from moving around on busy stages.
