The Stewart ADB-1 is a single channel active direct box that allows an unbalanced source to directly feed a balanced input. Musical instruments, tape recorders, VCRs and sound projectors can be run "direct" to the mixing console, avoiding unnecessary degradation of sound quality. The ADB-1 operates on either phantom power or a 9-volt battery.
FEATURES: Flat response Low distortion Low noise Wide dynamic range No transformer RF protection on input and output Switchable ground isolation Flush mounted slide switches | 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. |
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.

Phantom or battery powered in a rugged steel chassis 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. Rear panel showing Left and Right XLR connectors, ground lift switch, battery check switch and LED, plus phantom power On LED and captive screw for opening up the unit for battery changing 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.
