ADI-1

Active Direct Inject Box

Introduction

Congratulations for purchasing the ADI-1 Active Direct Inject Box. This unique unit is the
ultimate, multi-functional active DI box. The ADI-1 is indispensable for solving many audio
mismatch and hum problems in numerous stage and studio applications.

• Eliminates impedance mismatch problems and converts any sound source at
almost any level (from guitar to speaker inputs) into a clean, powerful hum-free,
noise-free and interference-free balanced signal perfect for even extremely long
cable runs

• Full-featured controls and connections include On/Off, Ground Lift, and Guitar/
Speaker Source Select input attenuation switches; unbalanced 1/4" TS Input and
Parallel Link Output jacks; and servo-balanced XLR Output jack.

• Parallel link output allows ultimate hookup flexibility by enabling applications such
as connection to the input of the backline or monitor amplifier.

• No compromise circuit design and stringent component selection provide
absolutely flat, full frequency response across the entire audio spectrum, and
negligible distortion for the most natural, powerful audio available.

• Portable aircraft aluminum extruded case for ultimate roadworthiness, long life and
reliability

• Powered either by console’s +48V phantom power or internal 9V battery

Controls and Connections

(1A)

(1)

(1) ON/OFF BUTTON

When pressed, this enables the 9V battery power for the unit. If the device connected to
the ADI-1 XLR output has 25V-48V phantom power enabled, the ADI-1 can be used
without draining the 9V battery. Disabling the ON/OFF button will save battery power
when using phantom power.

(1A) POWER ON INDICATOR

This LED lights whenever the unit is on, either from external phantom power, or from
internal battery power when the unit is switched ON.

CAUTION: Always turn on the ADI-1 before turning up the volume on devices connected
to the ADI-1 outputs to avoid damaging your equipment or speakers.

(2) GROUND LIFT BUTTON

When pressed, this disconnects the ground connection between the 1/4" input and XLR
output to eliminate hum caused by ground loops.
