Working with the pedigree of our industry standard DI Plus and DI Plus 2 Direct Boxes, we've redesigned and updated our circuitry and packaging, and the end result is our new DI Plus RC Direct Box.
As a manufacturer, ARX is well aware of the problems of disposing of batteries in an environmentally friendly way so we've powered the DI Plus2 RC with an internal long life NiMH (Nickel Metal Hydride) rechargeable battery that can be charged off either the phantom power on the mic line, or via the 12V DC input, removing battery "throw away" as an issue.
The new DI Plus RC features a low noise high impedance input buffer with switchable 20dB Pad, and a low distortion high current output stage able to drive the longest cable runs. It represents another major step forward in active direct boxes. Packaged in a single channel stand-alone format, the DI Plus RC represents a fresh look at active D.I. concepts.
Ultra quiet, ultra clean circuitry delivers maximum headroom whatever the signal. Premium grade components, plus an all-steel chassis gives excellent hum and noise specifications and superb audio quality in a tough, roadworthy package.
The DI Plus RC features a Normal gain high impedance unbalanced input on the front panel, running to a balanced XLR output on the rear. There is also a separate -40dB Speaker Level input for signal coming from the External (auxiliary) speaker output of an amplifier. A global Pad switch drops both the normal input and the speaker input by a further 20dB, making it suitable for all applications, from the softest keyboard to the hottest broadcast levels.
Automatic Phantom switching
The DI Plus RC will automatically switch itself to the console's own Phantom Power, if available, and an LED will indicate this mode. Turn the Phantom Power off and it will instantly revert back to battery mode.
Rugged all-steel case
A lot of direct boxes are fitted into brittle cast alloy cases. Not this one! The tough all-steel inner and outer chassis of the DI Plus RC provide excellent RF/EMF shielding while making it a sturdy, heavy duty unit that is hard to dislodge, and hard to leave behind.

Whether you're a Studio or Live Sound engineer, installation contractor, or broadcast engineer, you want all the dynamics and clarity of the original sound source transferred to the mixing console. The ARX DI Plus RC provides a rugged, no-compromise solution to all direct injection and signal balancing requirements.
The DI-Plus RC are built on the AudiBox PLUS platform, which allows for a slightly enlarged chassis in order to fit all the components and rechargeable battery in!
