Content

Passive direct box for connection of unbalanced musical instruments
and line-level sources to low-Z balanced microphone input for PA or
recording. Not recommended for speaker-level use. 1/4" (6.35mm) input
(with parallel 1/4" output). Switch for ground lift. Male XLR-type balanced
mic-level output. Uses Pro Co CBT-1 transformer (20k/150 ohm).

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.

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.

  • Parallel 1/4" Thru Jack
  • Transformer Isolated
  • Premium Shielded Custom dbx Transformer
  • Balanced XLR Lo-Z Output
  • 3-Way 0/20/40 dB Pad Switch
