The Behringer Ultra-DI Pro DI4000 4-channel Active DI Box gives you four top-shelf DI channels in one rack space. Direct Injection (DI) boxes, of course, let you plug guitars and basses, keyboards, etc. directly into your board. For impedance matching and signal integrity, they\'re indispensable. The DI4000 is a DI on steroids. With its active circuitry, it sports buffered inputs that won\'t pollute your signal (as passive DIs can). Boasting a bevy of boost/attenuation, groundlift, and connectivity options, Behringer\'s Ultra-DI Pro DI4000 is your audio Swiss Army Knife.

Phantom or battery powered in a rugged steel chassis, with separate Speaker Level input connector
The ARX DI-PLUS represents another major step forward in active direct boxes. Packaged in
a single channel stand-alone format, the DI-PLUS represents a fresh look at active 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.
Level control
The DI-PLUS features a Normal gain high impedance unbalanced input on the front panel, running to
a balanced XLR output on the rear. There is also a separate -40dB Speaker Level input for signal coming
from the External (auxiliary) speaker output of an amplifier. A a global Pad switch drops both the normal
input and the speaker input by a further 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 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 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 provide excellent RF/EMF shielding while making it a sturdy, heavy duty unit that is
hard to dislodge, and hard to leave behind.

for battery changing
Whether you're a Studio or Live Sound engineer, installation contractor, or broadcast engineer, you want all
the dynamics and clarity of the original sound source transferred to the mixing console. The ARX DI-PLUS
provides a rugged, no-compromise solution to all direct injection and signal balancing requirements.

No tools required
| Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during phantom power operation. Metal case 110 x 73 x 42 mm. |
Passive DI box especially designed for guitars.
The PDI09 can be connected between an effect device or amplifier and the mixing console. The PDI09 is not suitable for direct connection to a guitar. Integrated filter circuits simulate the authentic "speaker" sound. Tone can be varied between "Mellow“, "Normal“, or "Bright“.
Technical specifications:
- Input: 6.3 mm jack with parallel "THRU" socket
- Output: male XLR transformer balanced
- Attenuator: (Level switch) 0 dB for line signals, -15 dB for small amps up to 10 w, 30 dB for large amps up to 200 w
- No battery necessary
