The ARX DI-1 is a major step for-
ward in active direct boxes. Using
a single channel based on the suc-
cessful 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 com-
plex signal. Gain is fully adjustable
from 0 dB through to +20 dB, mak-
ing 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. Produc-
tion 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 Phan-
tom Power off and it will revert back
to battery mode.
• Multiple power options
The DI-1 runs on 2 x 9 volt batter-
ies, 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 dis-
lodge, hard to leave behind, and also
harder for people to put in their
pockets!
Whether you’re a Studio or Live
Sound engineer, installation contrac-
tor, or broadcast engineer, you want
all the dynamics and clarity of the
original sound transferred to the
mixing console. If you’re a musi-
cian, 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.
