IMGSTAGELINE DIB-100 Passive DI Box
Product Information
Specifications
- 1 symmetrical output (XLR)
- Ground lift switch to interrupt the ground connection between the input and output
- 1 asymmetrical input (6.3mm jack)
- 1 asymmetrical through output (6.3mm jack) for taking the signal from the input jack
Product Usage Instructions
-
Applications
The DI Box (Direct Injection) DIB-100 is designed for connecting a musical instrument with an unbalanced, high-impedance output to a balanced, low- impedance input of a mixer. This setup helps prevent interference, especially over long cable runs. -
Features
- Attenuator for reducing high signal levels
- Direct connection to the speaker output of an instrument amplifier
- Maintains the sound quality of the signal through the amplifier
-
Operating Instructions
-
Connect the musical instrument with unbalanced output to the DI Box’s asymmetrical input using a 6.3mm jack cable.
-
Connect the DI Box’s symmetrical output (XLR) to the mixer’s balanced, low-impedance input.
-
If needed, use the groundlift switch to interrupt the ground connection between the input and output for troubleshooting ground loop issues.
-
To reduce high signal levels, adjust the attenuator on the DI Box accordingly to match the mixer’s input level.
-
If connecting directly to a speaker output of an instrument amplifier, ensure to maintain the sound quality of the signal through the amplifier.
FAQ
-
Q: What is the purpose of a DI Box?
A: A DI Box helps in connecting musical instruments with unbalanced, high- impedance outputs to balanced, low-impedance inputs on mixers, preventing interference and maintaining sound quality. -
Q: When should I use the groundlift switch on the DI Box?
A: The ground-lift switch should be used when troubleshooting ground loop issues by interrupting the ground connection between the input and output of the DI Box.

DI Box
These instructions are intended for users with basic knowledge of audio
technology. Please read these instructions carefully before operation and keep
them for later reference.
Applications
- The DI Box (Direct Injection) DIB-100 has been designed for the optimum connection of a musical instrument with an unbalanced, high-impedance output to a balanced, low-impedance input of a mixer (see fig. 2). Due to the balanced connection to the mixer, interferences can be prevented even in case of long connection cables.
- High signal levels can be reduced with the attenuator and be matched to the mixer input. Thus, the DI Box can also be directly connected to the speaker output of an instrument amplifier (e. g. guitar amplifier). Consequently, the effect of the amplifier on the sound of the signal is maintained.
Important Instructions for Use
The product corresponds to all relevant directives of the EU and is therefore marked with. The product corresponds to the relevant UK legislation and is therefore marked with UKCA.
- The product is suitable for indoor use only. Protect it against dripping water, splash water, and high air humidity. The admissible ambient temperature range is 0 – 40 °C.
- For cleaning only use a dry, soft cloth; never use water or chemicals.
- No guarantee claims for the product and no liability for any resulting personal damage or material damage will be accepted if the product is not correctly used or not expertly repaired.
- If the product is to be put out of opera-tion definitively, dispose of the product under local regulations.
Setting into Operation
The DI Box does not require a power supply.
Connecting the unbalanced input
Connect the output of the musical instrument to the input jack “INPUT” (3).
Alternatively, the input jack can also be connected to the speaker output of
an instrument amplifier.
Attention!
Never connect speaker outputs of amplifiers operating in the bridge circuit;
the DI Box will short-circuit them.
If the switch “ATT.” (5) is at the left stop at “0 dB”, the level of the input signal is not attenuated. If distortions occur on the following mixer, set the switch to position “−20” or, in case of very high signals, to position “−40”.
Connecting the balanced output
The balanced output signal is available at the XLR output (1). Connect the
output via a balanced cable to a highly sensitive input of a mixer (e. g.
microphone input).
Using the feedthrough output
For feeding the instrument signal simultaneously to an amplifier, connect the
amplifier input to the jack “PAR. OUT” (4) [see fig. 2]. This is where the
signal coming from the instrument is directly applied.
Attention!
The feedthrough output is not suitable for connecting speakers. Risk of
overload!
Groundlift switch
If the ground lift switch (2) is in the “OFF” position, the ground of the
unbalanced input (3) is connected to the ground of the balanced output (1).
This switch position should be chosen first. However, in the case of hum
loops, set the switch to the position “ON” (grounds separated).
