The Hosa DIB-443 Sidekick is a compact, transformer-based passive direct injection (DI) box designed to connect unbalanced instruments—such as electric guitars, basses, or keyboards—directly to a mixing console or recording interface.
Key Features:
Circuit Type: Passive (requires no batteries or external power)
Connectors: 1/4-inch TS input to a balanced XLR 3-pin male output (plus a 1/4-inch thru/output jack)
Isolation Transformer: Converts an unbalanced, high-impedance instrument signal into a balanced, low-impedance signal suitable for long cable runs to a mixer.
INST/LINE (or INST/SPKR) Switch: Allows you to toggle how the signal is handled, letting you run clean direct tones or route an amplifier's speaker output safely into the line.
Ground Lift Switch: Breaks the ground connection to help eliminate unwanted 60Hz ground-loop hum and electrical noise
