Power Requirements

The DI-PLUS2-RC is an active device, ie. it needs power to run. This power can be supplied 2 ways:

• Battery power

In a world first for this type of device, the DI-PLUS2-RC is fitted internally with a State-of-the-Art

Nickel Metal Hydride (NiMH) rechargeable battery. NiMH batteries do not suffer from the memory-effect that plagued earlier Nickel Cadmium (NiCad) batteries, and gradually reduced the amount of power available after each recharge. If you ever owned an earlier analog mobile/cell phone you'd be aware of this unfortunate phenomenon.

These new NiMH batteries also feature extended battery life, to last through the longest show.

• Phantom power

The DI-PLUS2-RC will also run on

Phantom power if available on the mixing console. Switch the Phantom power ON on the channel the DI-

PLUS2-RC is plugged into, and the

Red Phantom power LED will light up on the DI-PLUS2-RC. This means the DI-PLUS2-RC is now running on the Phantom power and the batteries are recharging. If you switch the

Phantom power off the DI-PLUS2-

RC will revert to battery operation.

PLEASE NOTE:

To charge from Phantom Power the

DI-PLUS2-RC needs to be switched on, i.e. a jack must be inserted into one of the INPUTS.

This is not required if the unit is being charged from an external power supply via the DC jack input.

Did you know...

As well as the DI-PLUS-RC and the

DI DI-PLUS2-RC, ARX manufacture a six channel rack mount AC powered Direct box:

The DI-6SM is a 19” 1 RU AC powered unit that has 6 independent Direct boxes, each with high impedance Input and Loop out jack connectors, a oo to +15dB level control, clip LED, balanced XLR output and individual audio ground lift switches. It can also function as a 6 into 1 mic or line mixer at the same

time.

Switches on the rear change it from a 6 into 1 mixer to a 1 into 6 mic or line distribution splitter, each split’s level controlled by the six individual channel controls.

A true Pro Audio toolbox!

Using the DI-PLUS2-RC

The DI-PLUS2-RC 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 ordinary 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 uses are:

• Musical instruments - Keyboards, synthesizers, electronic drums, drum machines

• Consumer audio products - CD players, cassette decks, tape decks, video cassette audio, computers.

Operating instructions

channel to the amplifier. Pushing the

Pad switch IN will reduce both input levels by -20dB if required.

Note: If you are only using One channel of the DI-PLUS 2-RC, make sure that you use Channel A. The

Channel A Input jack switches the

DI-PLUS2-RC on.

Special Note. The DI-PLUS2-RC 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 rear of the DI-PLUS2-RC to a pair of input channels on the mixing console. Pan the channels Left or

Right as required.

Pushing the Audio Ground Lift switch IN will isolate both Pin 1 outputs of the DI-PLUS 2-RC to stop

Ground Loops if required.

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).

If the signal needs monitoring, eg.

an onstage amplifier, then connect a lead from the Loop Outs of each
