BEHRINGER / DI4000 V2

This rack-mountable 4-channel direct box (DI) offers a wide range of functions and inputs/outputs to meet a wide range of needs.

Rackmount 4-Channel Direct Box (DI)
The DI4000 provides four first-class DI channels in a 1U rack space. Each channel features two inputs (XLR and 1/4"" TRS), a balanced XLR output, and a 1/4"" link output for connecting to an amplifier or monitor console. Additionally, the DI4000 is designed to accommodate virtually any input signal, with up to 40dB of switchable input attenuation and up to 20dB of gain, and the acclaimed OT-1 output transformer ensures a natural, powerful output.

PRO-Active
The DI lets you connect guitars, basses, keyboards (and other line-level devices) to an audio mixer or recorder. The DI4000 elevates DI boxes with a special 8kHz high-cut filter per channel for guitar applications and a phase-reverse switch for optimal signal conditioning. What's more, our DI4000 active DI features a buffered input that respects the source signal far better than passive DI boxes, outputting an optimally balanced, extremely low-impedance (600Ω) signal that's far less susceptible to noise and RF interference (RFI).

Rich Inputs and Outputs
The DI4000 is not simply a ""bass guitar input, mic-level output"" solution. The DI4000 can also connect a guitar amplifier's speaker output to a mixer. The DI4000 has two -20dB attenuation switches per channel, allowing you to connect speaker outputs rated up to 3,000 watts and convert them to balanced XLR outputs. Conversely, for weaker signals, the DI4000 has a +20dB switch, boosting low-level input signals into a balanced signal with true power and unwavering impact. Of course, the DI4000 also features a link output for easy connection to other equipment, such as on-stage amplifiers or monitor consoles. Servo-balanced performance ensures a flat frequency response. Gold-plated XLR output connectors ensure reliable, low-noise operation. Per-channel ground lift switches eliminate ground loop hum problems. The DI4000 does everything a standalone DI can do, and then four times more!
