Using your Audibox
The AV-DI is a Direct Injection, or
Direct, box. It is a self contained,
stand alone stereo unit designed to
interface a left and right pair of un-
balanced high impedance lines with
professional balanced low imped-
ance inputs. In other words, it will
convert consumer audio signals into
ones that are happy to travel down
a long line and meet a mixing con-
sole at the other end. It has many
applications for Live Sound, Studio
or Broadcast use.
Typical input types are:
• Consumer audio products - MP3
players, laptop computer sound
cards, CD players, audio from DVD
players, cassette decks, tape decks,
VCR audio and more
Operating instructions
Input Connections
A stereo high
impedance source (instrument, un-
balanced lines or similar) plugs into
Inputs A and B (typically Left to A
and Right to B). Pushing the Pad
switch IN will reduce both input lev-
els by -20dB if required.
Special Note. The AV-DI is a Line
level device, so it is not designed to
accept Microphone level signals.
Output Connections
Connect a
balanced microphone lead from
each 3 pin XLR connector on the

the mixing console. Pan the channels
Left or Right as required.
The full-time Soft Ground connection
Grounds both Pin 1 outputs of the AV-
DI through a resistive network to pre-
vent Ground Loops.
Power Requirements
The AV-DI is an active device,
ie.
it
needs power to run. This power can
be supplied 2 ways:
•
Phantom power:
The AV-DI will
also run on Phantom power if avail-
able on the console. Switch the Phan-
tom power ON on the channel(s) the
AV-DI is plugged into, and the Phan-
tom power LED will light up on the
AV-DI to show that it is running on
Phantom power
.
• External 12 - 15 V DC power:
The AV-DI has a DC input connector
for running the unit on an external 12
- 15 V DC power supply. Any 12V DC
wall connector capable of supplying
200 mAmps will work, although for
greatest headroom we recommend
the Audibox PSU which can supply 15
V DC to multiple Audibox devices.
Note the wiring of the connector: the
outer sleeve is –, the inner is +.
