Nothing balances and isolates a signal like a transformer, and Crimson makes a couple of standard models specifically designed for line output applications. The Crimson 4000A Line Isolator and it’s little brother, the 4000B, are both precision wound using a bifilar winding technique for high common mode rejection. They use nickel steel core material for the lowest distortion and highest fidelity at line levels. And the tough steel case has two mounting points so they stay where you put them, despite the rigors of the road.
So whether you’ve got a long run of cable you want as quiet as possible, or multiple amplifiers you want to isolate from each other, Crimson Line Isolators can give you that bullet proof confidence.
