Behringer DI-400P High-Performance Passive Direct Injection Box

Introducing the Ultra-Compact DI-Boxes from BEHRINGER

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that?ll corrupt the signal.

The DI400P lets you connect instruments or amplifier outputs. It converts any unbalanced signal to a balanced signal and eliminates unwanted noise. With its high-performance transformer, it also allows you to use very long cables without the loss of high frequencies.

This is the sort of medicine that?ll cure headaches in your studio or on stage.

DI box παθητικό 1-channel DI box, passive Converts unbalanced 6.3 mm jack line input (e.g. from instruments) into balanced XLR output for connecting a mixer Switchable input attenuation: 0 dB, -20 dB, -40 dB Ground-lift switch eliminates ground loop problems 1 signal input (6.3 mm jack) 1 parallel output (6.3 mm jack), feed-through of the input signal 1 low-impedance output (XLR) Gray housing

You're serious about getting rid of all that excess noise on stage, but you've got so many line
instruments you don't know where to start. The ADB-4 from Stewart can take care of all your
high impedance problems. The ADB-4 is 4 active direct boxes, all in a module that only takes
up half a space on your keyboard rack. It's a rugged, durable piece of equipment that packs a
lot of DI power.

Inline Transformer IA-2

The model IA-2 line matching transformers !S designed to properly match a low impedance
signal to a low impedance source. The advantage of "ground lift" switching allows to optmize
hum problems.

The ARX DI-PLUS 2 represents another major step forward in active direct boxes. Packaged in
a single channel stand-alone format, the DI-PLUS 2 represents a fresh look at active stereo
D.I. concepts.

Precision engineered
Ultra quiet, ultra clean circuitry delivers maximum headroom whatever the signal. Premium grade
components, plus an all-steel chassis gives excellent hum and noise specifications and superb
audio quality in a tough, roadworthy package. Accurate Left and Right channel level matching keeps
the stereo image centred.

Level control
The DI-PLUS 2 features two high impedance unbalanced inputs on the front panel, running to balanced
XLR outputs on the rear. A a global Pad switch drops inputs by 20dB, making it suitable for all applications
from the softest keyboard to the hottest broadcast levels.
 
Battery compartment
The revolutionary simple 'clamshell' action of the DI-PLUS 2 battery compartment makes battery changing
extremely easy, even on the darkest stages.
A 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 2 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 2 provide excellent 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 contractor, or broadcast engineer, you want all
the dynamics,clarity and stereo information of the original sound source transferred to the mixing console.
The ARX DI-PLUS 2 provides a rugged, no-compromise solution to all stereo direct injection and signal
balancing requirements.
