DI-1
Single Channel Active Direct Box
Phantom, Battery or Plug Pack powered in a rugged steel chassis http://www.arx.com.au
The ARX DI-1 is a major step forward in active direct boxes. Using a single channel based on the successful DI-6, the DI-1 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 a steel chassis gives excellent hum and noise specifications in a tough, roadworthy package.
• Gain control
By using a rotary control rather than a simple switch, the DI-1 can be set up to handle the most complex signal. Gain is fully adjustable from 0 dB through to +20 dB, making it suitable for all applications, from the softest keyboard to the hottest broadcast levels.
• Battery compartment
The simple ‘twist-and-slide’ action of the DI-1 battery compartment makes battery changing a breeze, even on the darkest stages. No tools required, no screws to lose. Production crew heaven!
•Automatic Phantom switching
The DI-1 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 revert back to battery mode.
• Multiple power options
The DI-1 runs on 2 x 9 volt batteries, but if they die, it also has a DC input connector, so you can run it from any DC power pack such as a guitar pedal power supply. Now the show can go on, whatever happens.
• Not too compact
A lot of direct boxes are fitted into brittle cast alloy cases. Not this one!
The custom aluminium extrusion surrounding the DI-1, plus its steel innner chassis with 2 batteries make it a solid unit that is hard to dislodge, hard to leave behind, and also harder for people to put in their pockets!
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 transferred to the mixing console. If you’re a musician, then you need to be sure that what you play is what the audience hears. After all, if your sound isn’t important, why bother playing?
The ARX DI-1 provides a rugged, no-compromise solution to all direct injection signal requirements.

• Not too compact
A lot of other direct boxes are fitted into brittle cast alloy cases. Not this one! Computer aided high density design has allowed ARX to slip two channels of ultra high quality DI circuitry into the same custom aluminium extrusion that surrounds the DI-2, making it a solid unit that is hard to dislodge, hard to leave behind, and also harder for people to put in their pockets!
