A 2-channel active stereo direct box providing direct insertion of a STEREO audio signal into a STEREO mixer or recorder. A variety of audio signals can be connected to your DI-2, e.g. guitars, bass guitars, drum machines, keyboards, outboard signal processors, high powered speaker output from an amplifier etc. Besides that the DI-1 is also useful for connecting imbalanced signals such as DJ mixers, effects processors and keyboards to a main PA or recording mixer. The DI-2 can be powered either by a single 9 volt battery or standard 48 volt phantom power. The DI-2 enables you to tap off the signal from a guitar or bass guitar and pass the signal from the THRU output to the guitar / bass guitar amplifier without affecting the original sound.The OUTPUT connection gives cancellation of hums/buzzes while leaving the original signal clean and pure. The device comes in a sturdy aluminum shell with stabilizing rubber grip feet.
