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 unbalanced high impedance lines with professional balanced low impedance 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 console 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, unbalanced 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 levels 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

AV-DI to a pair of input channels on 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 prevent 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 available on the console. Switch the Phantom power ON on the channel(s) the AV-DI is plugged into, and the Phantom 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 +.

Did you know ...

As well as the AV-DI, ARX manu- facture other products in the unique Audibox range:

The ISO-Balancer for balancing unbalanced signals, and also the ISO De-Balancer, which will de-balance a signal when required to connect to an unbalanced input.

The ISO-Later is a Dual channel Unbalanced to Balanced Low Impedance transformer isolated converter, and the ISO Splitter is a transformer isolated 1 input to 2 outputs splitter for splitting 1 input 2 ways in applications where complete Galvanic isolation is required.

Both available in Single Channel or Double Header format.

The Ear Driver is a Headphone Amplifier with 2 pairs of Stereo inputs each feeding two channels of headphone level outputs. It has individual Level controls plus a 12 15VDC power connector. A compact, flexible unit

The P ro-DI is an ultra compact Active Direct box, with normal High Impedance input as well as a separate speaker level input for connection to instrument amplifiers.

Other features include –20dB Pad and Audio Ground Lift switches,
