Thank you for choosing this ARX DI-

PLUS

, a major step forward in active

direct boxes. We hope you enjoy us-

ing this unique product as much as we

enjoyed creating it. As with all ARX

equipment, it has undergone exten-

sive factory testing and ‘burn in’ be-

fore shipping. To ensure continued

trouble free use, please familiarise

yourself with the contents of this

manual before using.

Packaged in a single channel stand-

alone format, the DI-

PLUS

represents

a fresh look at active D.I. require-

ments.

• Precision engineered

Ultra quiet, ultra clean circuitry de-

livers maximum headroom whatever

the signal. Premium grade compo-

nents, plus an all-steel chassis gives

excellent hum and noise specifications

and superb audio quality in a tough,

roadworthy package.

• Level control

The DI-

PLUS

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 saparate -40dB Speaker Level in-

put for signal coming from the Ex-

ternal (auxiliary) speaker output of

an amplifier. A global Pad switch

drops both the Normal input and the

Speaker Level input by a further

20dB, making it suitable for all appli-

cations, from the softest keyboard to

the hottest broadcast levels.

• Battery compartment

The revolutionary simple ‘clamshell’

action of the DI-

PLUS

battery com-

partment makes battery changing

extremely easy, even on the darkest

stages. A single 9v alkaline battery

snaps into a PCB mounted battery

holder for fast, secure location. No

fragile battery clip leads to break, no

tools required, no screws to lose.

Production crew heaven!

• Automatic Phantom switching

The DI-

PLUS

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

provide ex-

cellent 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 contrac-

tor, or broadcast engineer, you want

all the dynamics and clarity of the

original sound source transferred to

the mixing console.

The ARX DI-

PLUS

provides a rug-

ged, no-compromise solution to all

direct injection and signal balancing

requirements.
