ACTIVE DIRECT BOXES AND RACK UNITS
 
i -DI Portable Media Active Direct Box   NEW!
Tablets and Smart Phones have rapidly become the audio source of choice for Corporate A.V. Presentations, Seminars, System Demos and Testing, Musicians, D.Js and many other audio system users. Designed by the ARX Engineering team to fill the market niche for a Portable Transformer Isolated Active Direct Box interface, the new i-DI connects all of today's (and tomorrow's) Tablets and Smart Phone devices to the Pro Audio world via a permanently anchored flying heavy duty input cable with a genuine Amphenol Pro Series minijack connector. Ultra low noise and distortion circuitry, plus electronically Balanced XLR outputs complete the i-DI package.

Applications
Corporate A.V Presentations
Seminars
System Demos and Testing
Musicians
D.J.'s / EDM

  • Phantom powered, there are no batteries to go flat during use
  • The i-DI does not use the digital interface cable, so many portable media devices are still able to be charged while playing
  • Full Transformer Ground isolation eliminates Ground Loop hum and Power Supply noise from AC  chargers, PSU, 'Wall warts' etc.
  • Electronically Balanced Outputs with ultra low (<10 Ohms) output impedance lets you drive long cable runs without signal loss
  • Load compensated and RF filtered Input ensures low distortion signal transfer
  • Audio Ground lift switch included for Pin 1 output connection. Switch in or out as required.
  • Ultra low distortion circuitry (.004% 0dB out) Frequency Response of 20 Hz to 20 KHz ±1dB
  • The i-DI is fitted into a Heavy duty all-steel chassis finished in attractive textured white powdercoat, with hardwearing epoxy screen printing and slip resistant rubber base pad
  • Security features include Kensington®-type computer lock slot and optional bracket kit for under-table mounting.

DI Plus RC Single Channel Active Direct Box with NiMH battery
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.

We've powered these new products with internal long life NiMH (Nickel Metal Hydride) rechargeable. NiMH batteries exhibit no memory effect and a long life recharge cycle.

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 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.

Precision engineered
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.

Managing Levels
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. 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.

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.

    DI6SM Six Channel Active Direct Box, Mic/Line Splitter & Line Mixer

    • All new Updated version of our Unique Pro Audio problem solver
    • Six Direct boxes, Mic or Line Splitter and Line Mixer in one unit!
    • Balanced XLR Mic input with Gain control
    • Multiple modes: Six in, Six out; Six in, One out; One in, Six out
    • Individual Output Ground lift switches
    • Up to +15dB Gain available per channel
    • Balanced XLR Outputs; High Impedance Jack Ins and Outs
    • Flawless performance in any audio environment
    Interfaces Unlimited
    MP3 players, Tape/cassette/DVD/CD decks, audio for video, drum machines, synthesizers, bass guitars, computers; at some stage all these need linking up to Balanced inputs, whether the application is Live sound, Studio or Broadcast.

    A Pro Audio Toolbox
    This unique and flexible audio toolbox allows Six independent unbalanced audio sources to easily and quietly interface with Balanced pro audio systems, either to individual channels or summed down to one Master output.

    But that's not all
    By pressing a single switch on the rear panel the DI-6SM will change modes from 6 Direct Boxes plus Mixer to being a 6 way Splitter (mic/line distribution amplifier). Now it will split an incoming microphone or line signal to 6 individual outputs or zones, with an XLR Loop Out to send the microphone output to a mixing desk as well. Switchable phantom power and Gain trim for the Mic input completes this new package

    On the front panel, each channel has 2 IN/OUT jacks, a level control from infinity (off) through 0dB to +15dB gain, and a Clip indicator LED.

    The Master section has a Master volume control and status LED’s indicating whether the unit is in DI+Mixer or in Splitter mode. For your convenience there is also a balanced jack Mix output on the front panel, in parallel with the balanced XLR Mix output on the rear panel.

    Balanced Outputs
    On the rear, each channel has an XLR Balanced output, with associated Ground lift switch and status LED, to isolate the chassis and electronic grounds.

    The Master section has a Balanced XLR output on the rear, and a Balanced Jack output on the front panel. In addition there is a Balanced XLR input with a switch to put the unit in either DI+Mixer or into Splitter mode. In Splitter mode there is a switch to toggle between Microphone and Line level input, as well as a Phantom Power switch and a Loop Output for a microphone signal to go to a Mixing desk as well

    Universal AC Power
    AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and voltage change switch.
