BEHRINGER ULTRA-DI DI600P
Thank you for showing confidence in BEHRINGER products by
purchasing the ULTRA-DI DI600P. The DI600P is a high-performance
passive direct injection box.

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 DI600P lets you
directly
tap into a high-impedance, unbalanced
signalfor example, the signal between a guitar and a guitar amp.
From there on, you can feed the signal directly to a mixing console.
1. CONTROL ELEMENTS

Use the
INPUT
(¼" TS) connector for connecting signal sources.
OUTPUT
(¼" TS). This is the unbalanced parallel output.
Connect it to the input of your backline or monitor amplifier.
Because the connectors
and
are wired in parallel, the
OUTPUT connector can be used both as an input and as a direct
unbalanced output of the INPUT signal. For the latter, you can for
example connect OUTPUT with the input of a monitor amplifier.
OUTPUT
(XLR): This is the balanced mic-level output. Use a
high-quality balanced microphone cable to establish
connection.
Using the
GND LIFT
(ground lift) switch, you can fully
separate input and output grounding. Depending on how the
equipment to which your DI600P is connected is grounded,
using the GND LIFT switch lets you lower hum noise or ground
loops. When the GND LIFT switch is in LIFT position, the
ground connection is interrupted.
The
INST/AMP
attenuation switch (30 dB) increases the
operating range of the DI600P considerably, from low signal
levels of a high-impedance mic or a guitar (INST), all the way
to speaker connectors of a guitar amplifier (AMP).
Switchable
FILTER
for guitar applications (7.5 kHz, -3 dB).

2. APPLICATIONS

This illustration shows the standard 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 DI600P after the
effects device, so that you can monitor the effects via the PA
system or the recording as well.
2.2 Taking a signal from a speaker output
Fig. 3: Connection to a power amp output
Sometimes, you want to take a signal directly from a speaker
output, even though just one speaker output is available. When
you set the INST/AMP switch to AMP, you can connect an amp
output to your mixing console (up to 3,000 Watts into 4 Ohms),
without worrying that it will be damaged due to overload!

If you are using a tube amp, you must connect a speaker
or a similar load resistance to the parallel ¼" TS OUTPUT.
