The DN200 Active Stereo Direct Injection Box from Klark Teknik is a dual-channel and multi-mode stereo DI box that delivers superior connectivity and audio performance. Housed in a robust alloy case with the same form factor as the DN100 Single-Channel DI, and further protected by a replaceable silicon sleeve, the DN200 features inputs on pairs of XLR, TRS, and RCA sockets, plus a switchable 20 dB pad and a ground lift switch.
In addition, the DN200 can operate in Sum mode, where left and right input signals are merged and routed to both left and right outputs, or Split mode, routing the left input signal to both the left and right outputs. The DN200 supports 24 to 48V phantom-power operation.

DOD AC 275 Active Direct Box with Switchable Ground Lift and Attenuator-2nd Hand- The AC 275 is an active, phantom powered direct box. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free. Housed in a cast alloy chassis, the AC 275 supplies two, high impedance, unbalanced 1/4" jacks and one low impedance balanced XLR jack. It operates with battery or phantom power.

The alphaton Direct Injection-Box SM-50 allows direct connection of electric guitars,
electric bass, and electronic music instruments with mixing desks of PA systems
and of recording studios.
The SM-50 reduces the amount of microphones used on stage, thus improving gain
before feedback.
Coloration of sound is avoided. Clean signal without interference from other instruments
eases the job of the recording engineer. The use of a strong aluminium die-cast box allows
trouble-free function for a number of years even under adverse conditions. Double grounding
(hum) can be eliminated by activating the built-in ground-lift switch. Isolation voltage between
input and output is 2500 volts, against ground 1500 volts (with ground-lift switch activated).
The box thus complies with toughest safety standards.

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.

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 |
