Behringer DI4000 Specification

The Behringer DI4000 is a professional-grade, four-channel direct injection box designed to interface high-impedance instruments with low-impedance balanced inputs. This unit is ideal for studio and live sound applications, offering superior audio quality and versatility. Each channel of the DI4000 features its own independent input and output, with the capacity to handle both instrument and line-level signals. The DI4000's wide frequency response ensures clear and accurate audio reproduction, while its ultra-low noise operational amplifiers maintain pristine signal integrity.

The unit is equipped with a switchable input attenuation of up to -30 dB, allowing it to accommodate a wide range of input levels without distortion. The ground lift switch on each channel aids in eliminating hum and ground loop issues, ensuring a clean signal path. Additionally, the DI4000 includes a switchable 20 dB output pad, providing further flexibility in matching output levels to the requirements of mixing consoles or recording devices.

Housed in a rugged, roadworthy 1U rack-mountable chassis, the DI4000 is built to withstand the demands of both studio and touring environments. The unit's design includes an internal switch-mode power supply, which operates efficiently on a range of voltages, ensuring consistent performance worldwide. With its combination of robust construction, versatile functionality, and superior audio performance, the Behringer DI4000 is an essential tool for audio professionals seeking to maintain signal clarity and integrity across multiple channels.

Behringer DI4000 F.A.Q.

How do I connect the Behringer DI4000 to a mixer?

To connect the DI4000 to a mixer, use an XLR cable to connect the output of the DI4000 to an input channel on your mixer. Ensure that the input gain on the mixer is set appropriately to avoid distortion.

What is the purpose of the ground lift switch on the DI4000?

The ground lift switch is used to eliminate ground loop hum. If you experience hum in your audio signal, activate the ground lift switch to break the ground loop and reduce noise.

How do I troubleshoot a distorted output from the DI4000?

First, check the input signal level to ensure it is not too high. Then, verify that the PAD switch is engaged if necessary to reduce input signal level. Finally, check all cables and connections for faults.

Can the DI4000 be used with an electric guitar?

Yes, the DI4000 can be used with an electric guitar. Connect the guitar to the input of the DI4000 using a standard 1/4" instrument cable. Use the output to connect to an amplifier or audio interface.

What maintenance does the DI4000 require?

The DI4000 requires minimal maintenance. Keep the unit clean and free of dust. Periodically check cables and connections for wear and replace them as necessary. Store the device in a dry, dust-free environment.

How can I prevent feedback when using the DI4000?

To prevent feedback, ensure that microphones and speakers are positioned correctly, avoid pointing microphones directly at speakers, and adjust the input gain levels appropriately on the DI4000.

What is the function of the PAD switch on the DI4000?

The PAD switch attenuates the input signal by -20 dB, allowing for the connection of high-level signals without overloading the input stage of the DI4000.

Is it possible to rack mount the DI4000?

Yes, the DI4000 is designed for rack mounting. It occupies a 1U space in a standard 19-inch rack, making it convenient for integration into professional audio setups.

How do I use the DI4000 to convert an unbalanced signal to a balanced signal?

Connect the unbalanced source to the input of the DI4000. The DI4000 will convert this signal to a balanced output, which you can then connect to your audio system using an XLR cable.

What should I do if the DI4000 is not powering on?

Check the power cable connections to ensure they are secure and that the outlet is functioning. Verify that the power switch is turned on. If the problem persists, consult the user manual or contact Behringer support.
