The Behringer DI4000 Ultra-DI Pro Direct Box makes it easy to connect several signals to your console without hum or other noises. Up to 40dB of switchable input attenuation lets you connect anything from unbalanced line and instrument signals, to an amp's output with up to 3,000W. There's even a built-in preamp to pump up weak signals. 4-channel DI also includes gold-plated XLR and 1/4" inputs/outputs, shielded internal power supply, 8-segment LED, and more. One rackspace.
