XtremPro Hi-end Ground Loop Noise Isolator / Filter for Car Audio / Home High-fidelity System - Black (65042) Introduction: A ground isolator is required if interconnection of several units has created a ground loop resulting in hum noise. It is mainly used in car Hafiz systems. The ground isolator is always inserted between two units with line connections. Features: THD: Transmission Ratio: 1: 1 Input/output impedance: 12 kO Frequency Range: 20-30, 000 Hz Gold-plated RCA Jacks / 2 Inputs, 2 Outputs How to Use: Connect the line outputs (e. g. of the car radio) via screened cables with phono connectors to the phono jacks INPUT of the ground isolator. Connect the phono jacks OUTPUT via screened cables with phono connectors to the line inputs of the following unit (e. g. of the power amplifier). Do not confuse the R/L channels.
