DB1P is a single-channel passive DI BOX equipped with the same type of MU-METAL core transformer used in the DB1A, which provides minimum distortion, linear phase and hum-free transmission also on very long cables. Thanks to the input stage design, DB1P can accept also signals coming directly from the power output of instrument amplifiers, PAD up to 60 dB. A specially designed input filter is also available for cutting any hiss or buzz noise coming from acoustic or electric guitar and basses.

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

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. |

Tube-buffered DI-Box DI-1000
The Tube-Buffered DI-Box DI-1000 allows the extraction of all the musical details of
musical interfaces without degrading the sound. This can only be achieved by
providing a very high input impedance to avoid any loading of instrument pickups.This
design approach allows seemingly infinite headroom to preserve the real dynamic range
of the interfaced instruments.A vacuum tube enables all these goals to be achieved
without any compromises in sound quality.The sonic difference between a standard
DI-Box and the Tube-Buffered DI-Box is comparable to the musical resolution difference
between a standard microphone and a studio microphone.One of the best transformers,
the very transparent sounding JENSEN JT-DB-E, was chosen providing complete ground
isolation. The parameters of this transformer, like frequency response, phase response,
group delay and geadroom capabilities, play a vital part in the performance of this DI-Box.
Technical Specifications
Input
The signal of the instrument is directly fed to the tube circuit with > 20 MOhms input
impedance to prevent any signal degradation, inevitable in traditional designs.
Buffered Output“
The second stage of the vacuum tube is used to buffer the signal and lower the output
impedance to < 8 kOhms. This unity gain output allows for cable runs of 10 meters
without loosing high frequency information.
Boost circuit
The boost circuit increases the signal send to the output transformer by 15 dB. This may
be useful for instruments with extremely low output, but decreases headroom capability
to 6 Volt rms. Under these circumstances the signal may be clipped, concerning the output
transformer?s signal, which gives you 2nd harmonic tube-like distortion. This distortion
normally does not occur - but is sometimes desirable, being the reason for this special feature.
Unity circuit
The unity circuit feeds a low distortion unity gain signal to the JENSEN output transformer.
This gives the best possible sound quality.
Ground-lift“-Switch
This front panel mounted switch allows complete ground and electrical isolation between the
direct injection box and the console or recording device.
Mechanical Specifications

accessible from the rear panel. IEC mains connector with optional fixture.
Construction details
Double sided glass fibre contacted PCB with 70 mm copper plating. 1% metal film resistors
and the finest polypropylene capacitors are used in the signal path. MIL type Switchcraft jacks
and high performance switches ensure flawless operation. The power supply is optimised via
measurement quality toroid transformer and a low impedance design to ensure the lowest
possible noise. Through a double sided PCB all parts are roadworthy secured. A waterclear
blue LED perfects the aesthetics of the DI box.
