The Radial SB-1 Acoustic is a high-performance active direct box made for players that are on the move. Made to fit inside a guitar case, the SB-1 is the smallest Radial DI box ever! But don't let the small size deter... this ultra-compact StageBug sounds absolutely terrific!
The design begins with standard ¼" instrument input with a thru-put to feed your tuner or your on-stage amp. The ultra quiet active circuit at once converts the signal from high to low impedance to reduce susceptibility to noise, buffers it and then balances the signal for long runs to the PA system. And with 48 volt phantom powering, the SB-1 does not require batteries or external supply to make it work. You simply plug in and you are set to go!
The active circuit features a carefully selected 220k-ohm input impedance to eliminate problems with loading while delivering a smooth, warm sound to the audio system. This is particularly important when interfacing vintage guitars with low output pickups when should you plan to do some recording or Reamping. The SB-1 is also equipped with a -15dB pad that reduces the input sensitivity to gracefully handle even the loudest instruments. This makes the SB-1 perfectly well suited for electric bass and keyboards. To reduce feedback, toggling the 180° polarity switch helps eliminate hot spots on stage that can cause low frequency resonance.

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.

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.

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.
