MONACOR INTERNATIONAL DIB-102 2 Channel DI Box
2-Channel DI Box
These instructions are intended for users with basic knowledge of audio technology. Please read the instructions carefully prior to operation and keep them for later reference.
Applications
The DI Box (Direct Injection) allows for optimal connection of a musical instrument with a high-impedance, unbalanced output to a low-impedance, balanced input of a mixer (see figure on page 11). Due to the balanced connection to the mixer, interference can be avoided even when long connection cables are used. If hum loops occur, the ground connection between the instrument and the mixer can be interrupted by means of the ground lift switch.
High signal levels can be reduced by means of the attenuator and matched to the mixer input. Thus, the DI Box can also be connected directly to the speaker output of an instrument amplifier; the effect of the amplifier (e. g. guitar amplifier or tube amplifier) on the sound will be maintained at the mixer input.
Overview for channel A
(channel B is identical)
- XLR output jack, bal.
- Ground lift switch
- Input jack, unbal.
- Parallel feed-through jack, unbal.
- Sliding switch to attenuate the input signal
Important Notes
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 operation definitively, dispose of the product in accordance with local regulations.
Operation
The DI Box does not need any power supply. In the text below, only channel A is described. Proceed in the same way to set channel B into operation.
Connection of the input
Connect the output of the musical instrument to the jack INPUT (3). Set the sliding switch ATT. (5) to the left stop (“0dB”).
If there are any distortions on the subsequent mixer, set the switch to the position “−20” or, in case of very high signal levels, to the position “−40”.
Alternatively, connect the input jack to the speaker output of an instrument amplifier to transmit the effect of the amplifier on the sound.
Attention!
Do not connect speaker outputs of amplifiers operating in bridge mode; they
will be short-circuited by the DI Box.
The output voltage of the amplifier must not exceed 32V; otherwise, the DI Box
may be overloaded. This means: 125W with an 8Ω speaker or 250W with a 4Ω
speaker.
Set the sliding switch ATT. (5) to the right stop (“−40”), or, if necessary, in case of low volume, to the mid-position “−20”.
Using the feed-through output
To route the instrument signal directly to an amplifier, connect the amplifier input to the jack PAR. OUT (4). The signal received from the instrument is directly available at this jack.
Attention!
The feed-through output is not suitable for connecting speakers. Risk of
overload!
Connecting the balanced output
Use a balanced cable to connect the XLR jack OUTPUT (1) to a high-sensitivity input of a mixer (e. g. microphone input).
Ground lift switch
When the ground lift switch (2) is in the position “OFF”, 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 case of hum loops, set the switch to the position “ON” (grounds separated).
