Behringer DI4000 audio module 3000 W RMS rated power

The Behringer DI4000 audio module 3000 W RMS rated power is a professional 4-channel active direct-injection (DI) unit designed for stage, studio and broadcast use. It provides impedance and signal matching for direct connection of instruments, speaker outputs and line-level sources to mixing consoles and recording equipment. Built with BEHRINGER OT-1 transformers for an ultra-flat frequency response and gold-plated XLR and 1/4" TRS connectors, the DI4000 supports high-power speaker connections and offers precise level monitoring through an 8-segment LED meter.

Advantages

The DI4000 accepts direct speaker output connections of up to 3,000 W RMS while maintaining low noise operation and clear signal integrity. Integrated features such as a +20 dB gain switch for preamplifying low-level signals, switchable input attenuation to handle high input levels, phase reverse and ground lift switches for easy troubleshooting, and an 8 kHz high-cut filter for guitar applications provide flexible routing and signal control. Illuminated switches aid operation in low-light situations and the unit includes a reliable LED level display for visual monitoring.

Suitable for

• Live sound reinforcement where direct speaker or instrument connections are required
• Studio recording for clean DI signals and accurate level control
• Broadcast setups needing reliable impedance matching and low-noise operation
• Stage rigs that require phase correction, ground lift, and high input handling

Key specifications

• 4-channel active DI configuration
• RMS rated speaker connection capacity up to 3000 W
• BEHRINGER OT-1 transformers for ultra-flat frequency response
• +20 dB gain switch for preamplification of low-level signals
• Switchable input attenuation allowing very high input levels
• Phase Reverse switch
• Switchable High-cut filter at 8 kHz
• Ground Lift switch to eliminate ground loop hum
• Accurate 8-segment LED level meter
• 1/4" TRS and gold-plated XLR connectors
• Illuminated control switches for low-light operation

How to use

Connect instruments, speaker outputs or line-level sources to the 1/4" TRS inputs and use the DI outputs to feed mixers or recording interfaces via the gold-plated XLR connectors. Use the +20 dB gain switch when connecting low-level signals and engage input attenuation when handling high-level sources. Apply the phase reverse switch to correct phase issues between channels and use the ground lift switch if ground-loop noise is present. Monitor levels with the 8-segment LED meter to avoid clipping and adjust attenuation or gain as required.

Recommendations

For reliable operation, verify input and speaker-level compatibility before connecting high-power outputs, enable attenuation when necessary, and use the ground lift and phase reverse functions to address noise and phasing problems. The high-cut filter is useful for taming excessive high-frequency content on guitars and similar sources.
