OMNITRONIC LH-070 Active 2-channel DI box/splitter

2-channel DI box/splitter, active Converts 2 separate unbalanced line inputs (e.g. instruments) into 2 balanced XLR outputs for connecting a mixer Switchable to split mode (input 1 routes the signal to both outputs) Switchable input attenuation: +20 dB, 0 dB, -30 dB Ground-lift switch eliminates ground loop problems 2 signal inputs via XLR connectors 2 low-impedance XLR outputs Microphone phase can be switched Hi cut 8 kHz switchable Modern convex housing design Full rubber housing corners for safe operation Cables can be routed under the housing Operation with 9 V battery

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.

? Requires phantom power or 9v battery
? Ground lift switch
? Instrument or speaker level switch
? Transformerless
? Can be used with amp up to 400w
? RF shielding

Passive 1-channel DI box, black

• 1 high-impedance signal input, 6.3 mm jack
• 1 low-impedance XLR output
• 6.35 mm jack input, and output
• Converts an unbalanced line input (e.g. instruments) into a balanced XLR output for connecting a mixer

• Rugged black metal housing

Package contents

• 1 x device, 1 x user manual

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

At dbx, when we do something, we do it right. So when we decided to create our new direct injection boxes, we didnʼt settle for the same old tired approach to direct box design. With our dbx name on the line, how could we? One look at our new dB10 Passive and dB12 Active direct boxes will tell you that these are clearly different. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally thereʼs a direct box worthy of the dbx name.

Utilizing custom dbx mu-metal-shielded audio transformers, high-quality Neutrik® connectors, and low-noise circuitry preserves the sonic integrity and true characteristics of the signal source. Both boxes include a pad switch that accomodates instrument, line and even speaker level signals. Take even more control of your sound by utilizing the polarity invert switch to set the phase relationship between the direct and mic'd sound.

As a professional, you donʼt have time for interference, so weʼve included a ground lift switch to solve potential hum and buzz problems due to ground loops. And between the combined shielding of the cast metal chassis and the custom-wound transformer, you can be doubly assured of a clean signal free from interference. All of this sits atop a solid, stable footprint, that will keep the box from being dragged around the stage, and the unique contoured underside allows secure stacking of multiple units.

So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx dB10 dB12 is for you.

Active DI-Box SM-60

The electronic Direct-Injection Box SM-60 allows direct connection of electronic
music instruments such as keyboards, synthesizers, electric and electronic pianos,
etc. with mixing consoles in PA-systems and in recording studios.
The SM-6 is designed for applications, where a passive DI-Box does not perfom
satisfactorily, i.e., where the output level of a passive DI-Box is too low for the microphone
input section of the mixing desk.
Because the input impedance of the SM-6 is above 5 MOhm, instrument outputs are
not loaded or in any other way adversely affected. The voltage ratio from input to output
is 1: 1 and is always sufficient for connection with any microphone input. Input connectors
are 1/4" phone jacks, output connector is a Switchcraft D3M; output is 600 Ohms,
transformer balanced. The output level may in certain cases overload microphone inputs -
the line input section of the mixing console must then be used for connecting the SM-6.
The unit operates with a 9 V battery or phantom powering from 24 to 48 volts.
