Behringer Ultra-DI DI20 Professional Active 2-Channel DI-Box/Splitter User Manual

1. Sarrera

The BEHRINGER ULTRA-DI DI20 is a versatile direct injection (DI) box designed for both stage and studio applications. It efficiently converts unbalanced 1/4'' TRS line inputs into balanced XLR outputs, providing impedance and signal matching for direct connection of instruments to mixers and amplifiers. Its unique Split mode allows for flexible signal routing, making it an indispensable tool for musicians and audio engineers.

2. Ezaugarri nagusiak

• Goi mailako soinua: Ultra-flat frequency response from 10Hz to 70kHz for pristine audio.
• Azken aldakortasuna: Converts unbalanced to balanced signals with 1/4" and XLR connectivity.
• Zarata gutxiko errendimendua: Exceptionally low noise floor of 100dBu for clear recordings.
• Inpedantzia optimizatua: Matches instrument or audio source impedance to prevent signal loss.
• Broad Gain Range: Selectable max input range of +12/+32/+52dBu for various input levels.
• Dual Channel/Split Mode: Functions as two independent DI boxes or splits a single signal to two outputs.
• Phantom Power or Battery Operation: Can be powered by mixer's phantom power or a 9V battery.
• Lurreko igogailua etengailua: Eliminates ground loop problems.
• Eraikuntza iraunkorra: Ultra-rugged, road-suitable metal case.

3. Konfigurazioa eta konexioak

The DI20 offers flexible connectivity for various audio setups. Ensure all connections are secure before powering on the unit.

• CH 1 IN (BAL/UNBAL): 1/4" TRS input for Channel 1. Accepts both balanced and unbalanced signals.
• CH 2 IN (CH 1 OUT LINK): 1/4" TRS input for Channel 2. Also functions as a link output for Channel 1 when in Split mode.
• CH 1 OUT (BAL/UNBAL): XLR output for Channel 1. Provides a balanced or unbalanced signal.
• CH 2 OUT (BAL/UNBAL): XLR output for Channel 2. Provides a balanced or unbalanced signal.
• ATTENUATION Switch: Adjusts input sensitivity (0 dB, 20 dB, 40 dB) to prevent clipping from hot signals.
• MODE Switch (LINK/2-CH): Selects operation mode. "2-CH" for two independent channels, "LINK" for splitting Channel 1's signal to both outputs.
• GROUND Switch (LIFT/GND): Lifts the ground connection to eliminate hum caused by ground loops.
• BATTERY Switch (ON/OFF): Powers the unit using a 9V battery.

3.2 Powering the DI20

The DI20 can be powered in two ways:

• 9V bateria: Insert a 9V battery into the compartment on the bottom of the unit. Ensure the BATTERY switch is set to "ON". The battery automatically shuts off when phantom power is applied.
• Botere boterea: Connect the XLR outputs to a mixer or device that provides +18V to +48V DC phantom power. The unit will automatically draw power from the phantom source.

4. Funtzionamendu moduak

The DI20 offers two primary operating modes, selectable via the MODE switch:

4.1 Two-Channel Mode (2-CH)

In this mode, the DI20 functions as two independent direct boxes. Each channel (CH 1 and CH 2) operates separately, converting its respective 1/4" input to an XLR output. This is ideal for connecting two different instruments (e.g., two guitars, or a guitar and a keyboard) to a mixer.

4.2 Link/Split Mode (LINK)

When the MODE switch is set to "LINK", the signal from CH 1 IN is split and sent to both CH 1 OUT and CH 2 OUT. This allows you to send a single instrument's signal to two different destinations simultaneously. For example, you can send one output to the main mixer for the house sound and the other to a guitar amplifier on stage jarraipena egiteko.

5. Mantentzea

The Behringer Ultra-DI DI20 is built for durability. To ensure its longevity:

• Mantendu unitatea garbi eta hautsik eta hondakinik gabe.
• Saihestu unitatea muturreko tenperatura edo hezetasunetara ipintzea.
• When not in use, switch the BATTERY to "OFF" to conserve battery life.
• If using battery power, replace the 9V battery when the indicator light dims or the audio signal weakens.

6. Arazoak

Ohiko arazoak eta haien konponbideak:

• Soinurik ez: Check all cable connections. Ensure the unit is powered (battery "ON" or phantom power active). Verify input and output levels.
• Burrunba edo burrunba: Activate the GROUND LIFT switch. Ensure all cables are in good condition and properly shielded. Check for other electrical interference in the setup.
• Soinu distortsionatua: Reduce the input signal level using the ATTENUATION switch (20 dB or 40 dB) if the source signal is too hot.
• Bateria azkar husten da: Ensure the BATTERY switch is set to "OFF" when the unit is not in use. Replace with a fresh 9V battery.
