ULTRA-DI DI400P
Thank you for showing confidence in Behringer products by purchasing the
ULTRA-DI DI400P. The DI400P is a high-performance
passive direct injection box.
◊ Please read the safety instructions that appear at the end of this
document.
Being on stage or in the studio, musicians often look for ways to connect
certain signal sources directly to the mixing console. Even though this
approach has obvious advantages, there are still some technical hurdles
obstructing its implementation. For example, keyboards seldom feature balanced
outputs, and guitars can not be directly connected to mixing consoles because
of the high impedance of guitar signals.
The DI400P lets you directly tap into a high-impedance, unbalanced signal—for
example, the signal between a guitar and a guitar amp.
From there on, you can feed the signal directly to a mixing console.
Control Elements and Connections
(1) + (2) PARALLEL IN/OUT (¼” TS): These connectors are used for
connecting unbalanced signal sources. Because both connectors are wired in
parallel, they can be used both as an input and as a direct output to loop the
signal through to a monitor amplifier.
(3) OUTPUT (XLR): This is the balanced mic-level output. Use a high-
quality balanced microphone cable to establish a connection.
(4) Using the GND LIFT (ground lift) switch, you can fully separate input
and output grounding. Depending on how the equipment to which your DI400P is
connected is grounded, using the GND LIFT switch lets you lower hum noise or
ground loops. When the GND LIFT switch is in the LIFT position, the ground
connection is interrupted.
The SERIAL NUMBER of the DI400P is located at the bottom.
Connecting an Instrument Signal
This illustration shows the application of a DI-box. The signal feeding the
amplifier remains unchanged; it is simply taken and routed into
the amp. The low-impedance balanced signal is forwarded to the mic input of
the mixing console. This application has its advantages particularly with bass
guitars because very few microphones can linearly transmit bass frequencies
with high signal levels. If you are using effects, insert the DI400P after the
effects device, so that you can monitor the effects via the PA system or the
recording as well.
