The Behringer Ultra-DI Pro DI4000 4-channel Active DI Box gives you four top-shelf DI channels in one rack space. Direct Injection (DI) boxes, of course, let you plug guitars and basses, keyboards, etc. directly into your board. For impedance matching and signal integrity, they\'re indispensable. The DI4000 is a DI on steroids. With its active circuitry, it sports buffered inputs that won\'t pollute your signal (as passive DIs can). Boasting a bevy of boost/attenuation, groundlift, and connectivity options, Behringer\'s Ultra-DI Pro DI4000 is your audio Swiss Army Knife.

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.

|With added functionality and enhanced audio performance, the AR-133 has been
designed to be more affordable for musicians, studios and PA companies.
The unit includes phantom power and battery supplies as standard. Should the
phantom power from the console fail or be accidentally switched off, the AR-133
automatically switches over to the internal 9V battery providing uninterrupted use.
The unit is housed in a rugged aluminium extrusion case, with robust polyurethane
end-cheeks which give the AR-133 a very distinctive look.
Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning
that the AR-133 can be used to convert unbalanced signals to a balanced output on
The arched case allows cables to run back underneath the unit from the end for neat
Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or
amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick
solutions to ground-loop problems.
The AR-133 uses an enhanced version of the same audio path as the AR-116, now
regarded by many people as a reference standard. The sound quality is legendary,
particularly on acoustic and bass guitars.
Numerous applications can be satisfied by the AR-133. For example, as well as the
traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier
outputs, and other electronic sources.An additional bonus is the ability to use the AR-133
as an active balancing device.

Conceived and designed by BEHRINGER Germany
With the DI100, you can rest assured that your sound source will reach the console balanced and noise-free. BEHRINGER's take on the all-important active DI box gives you functionality, durability and incredible sound at a remarkable price.
Plug into the DI100's balanced 1/4" TRS or XLR input, then send a signal to your console via the balanced XLR output. You can even plug your guitar or bass amp's speaker output into the DI100, which can handle ratings of up to 3,000 Watts and still deliver a perfect signal. It also features a 1/4" LINK jack to send your signal to an on-stage amplifier. The DI100 also has a switchable attenuation pad, allowing input levels of up to +50 dB. There is also a ground lift switch to eliminate noise associated with ground loops. The DI100 also features BEHRINGER's renowned OT-1 output transformer.
Superior Sound, Incredible Value
DI boxes are an essential part of any stage or studio, and the DI100 delivers the exceptional sound you expect, wrapped up in a rugged, road-proof aluminum case with stackable rubber corners.
|A Reamping-Box is mainly used in studios. It allows you to play back a recorded guitar signal and send it to a guitar amp, where it can again be taken and recorded by the microphone. This allows the sound engineer to take time to experiment with the sound of the instrument using different amplifiers.
The DACCAPO box ensures optimal impedance matching and eliminates ground loop hum through the use of a transformer. The signal level to the amplifier can be adjusted with a volume control.
