Product Overview
The Hosa DIB‑443 Sidekick Passive DI Box is a compact, no‑power‑required device that allows you to connect guitars, basses, keyboards, and other mono instruments directly to a mixer or audio interface via XLR, while converting the high-impedance unbalanced signal to a low-impedance balanced signal.

Why Use It & Benefits for Installers / Musicians
-
Noise & Interference Rejection
The isolation transformer helps eliminate hum and interference (especially over long cable runs) by decoupling ground loops.
-
Signal Matching
Converts high‑impedance unbalanced instrument signals into low‑impedance balanced signals suitable for long cable runs to mixers or audio interfaces, preserving signal integrity.
-
Flexible Routing
The parallel ¼″ output lets you continue to drive your amp while sending the balanced XLR feed to the console or recording system without needing extra splitting gear.
-
Zero Power Required
Because it’s passive, there’s no need for phantom power or batteries, reducing setup complexity and failure points.
-
Compact & Rugged
Its sturdy housing and small footprint make it easy to integrate into pedalboards, rack systems, or mobile rigs.
Example Installation / Usage Scenario
Imagine you’re on stage with a guitar and an amp. You want to send your signal to the house PA while still driving your amp locally. You connect your guitar → DIB‑443 input (¼″ TS) → amp input, and also send the DIB‑443’s XLR output to the mixing console’s channel. The ground lift switch helps reduce hum or buzz if you notice ground loop noise. Because the DIB‑443 is passive, you never need to worry about batteries running out mid‑gig.
In a recording setup, you could place the DIB‑443 between your instrument and the preamp or audio interface, letting you keep cables quiet and signal clean for capture.
