The DI 10A Active DI Box with Midas Transformer and Phantom/Battery Operation from Klark Teknik is designed to interface keyboards, samplers, guitars, and other electronic musical instruments to a mixing console. It can be used to reproduce the character of electric and acoustic instruments allowing more musical performance to be captured for live stage, theater, and rehearsals applications.
The DI 10A is powered by +48V phantom power with a 9V battery backup, which allows the device to function should phantom power fail. Equipped with a switchable input attenuator, XLR input, thru input, and 1/4″ input, the DI 10A accommodates instruments, line, and even loudspeaker-level signals. In addition, it provides extended dynamic range, making it a solution for professional audio and multimedia applications.
