Hosa SideKick DIB-445 Active Direct Box

The Hosa SideKick DIB-445 is a high-quality, value-priced active direct (DI) box designed for instrument signal routing in professional live sound and studio recording environments. As an active DI, it is perfect for scenarios requiring longer cable runs without introducing noise or interference. Its smart design and superior components make it an excellent choice for clean, hum-free recording in digital audio workstation (DAW) systems.

This DI box converts the unbalanced high-impedance output of instruments—such as guitars, basses, and keyboards—into a balanced low-impedance signal. Operating via convenient +48V phantom power from your mixer or audio interface, the SideKick DIB-445 features one unbalanced ¼” input, one balanced ¼” thru output, and one balanced XLR output. It maintains the natural sound of the input source, offering high headroom and low harmonic distortion. Its impressive audio specifications include a near-perfect flat frequency response of 20Hz to 20kHz with only ±0.2dB deviation, a superbly low noise specification of -95dBu (A-weighted), and THD+N at less than 0.005% at 1kHz, providing pristine audio quality that meets or exceeds the specs of other DI boxes at twice the price. Its sturdy all-metal housing ensures durability even under the most grueling touring conditions.
