Behringer ULTRA-DI DI600P Passive DI Box with Speaker Emulation

The Behringer ULTRA-DI DI600P stands out from typical passive DI boxes by combining a high-performance OT-1 transformer with a built-in 4x12 guitar cabinet emulation, delivering a rich, amp-like tone straight to the mixing console without the need for batteries or phantom power. This rugged, road-ready unit is engineered to preserve signal integrity and transient response, making it an indispensable tool for live sound engineers, studio musicians, and bass or keyboard players who demand reliability and sonic clarity.

Highlights

• Passive design requires no external power, eliminating battery hassles and ensuring consistent performance.
• Switchable input attenuation pad (0 dB, -20 dB, -40 dB) accommodates a wide range of signal levels, from instrument to speaker output.
• Ground lift switch effectively eliminates hum and buzz caused by ground loops.
• Dual 1/4" TS inputs (unbalanced) and a 1/4" TS link output allow simultaneous connection to an amplifier and a mixer.
• Balanced XLR output with 600 Ohm impedance ensures noise-free long cable runs.
• Speaker emulation filter recreates the sound of a 4x12 cabinet, ideal for direct recording or live performance.
• Ultra-low distortion and wide frequency response (10 Hz to 50 kHz) maintain audio fidelity.
• Robust metal chassis withstands the rigors of touring and frequent setup/teardown.

In daily use

Connect your electric guitar, bass, or keyboard directly to the DI600P's 1/4" input, and send the balanced XLR output to the mixing console or audio interface. The link output lets you simultaneously feed your stage amplifier for monitoring. When connecting to a speaker output, engage the appropriate pad to prevent overloading, and use the speaker emulation to capture the character of a miked cabinet. The ground lift switch is your first line of defense against hum in electrically noisy environments. Thanks to its passive circuitry, the DI600P operates transparently without coloring the signal, ensuring your instrument's true tone reaches the PA or recording system.
