Clair Brothers Line – Level Isolation Transformer Box 1990s - Black

This Clair Brothers Line-Level Isolation Transformer Box is in very good condition. It’s been around the world a few times on tour and works perfectly with high quality components. Part of the silk screen label describing the ground switch position has peeled off. It also has random scuffs on the finish.

Key Features & Functionality

• Design: 1:1 Jensen transformer and capacitor to block DC voltage (such as phantom power or intercom power supplies) while passing clean audio.
• Ground Loop Elimination: Resolves balanced line pins to ground to act as a line-level terminator and eliminate persistent hum and buzz. 
• Usage: Commonly deployed by professional road technicians for split feeds, long cable runs, and resolving grounding issues between consoles, drive racks, and press equipment.
