About Samson Isolation Box

Let the Samson MLI1 Mono Passive Isolation Box be your ultimate solution for pristine audio signal integrity in the most challenging environments. Engineered to tackle the common issue of hum and buzz interference, the MLI1 expertly eliminates noise caused by ground loops. This is achieved through its high-quality passive isolation design, which also adeptly converts unbalanced signals into balanced ones, making it ideal for maintaining signal clarity over long cable runs.

At the heart of the MLI1 lies Samson's proprietary STL transformer, renowned for its exceptional performance. It ensures an extended, ruler-flat frequency response ranging from 10Hz to 35kHz (with an impressive +/-0.2dB deviation), coupled with ultra-low distortion. This precision-engineered transformer is the cornerstone of the MLI1's ability to isolate the input from the output, effectively eradicating any DC noise that could compromise your audio quality.

The MLI1's Ground Lift switch is an indispensable feature for audio professionals. By severing the ground connection from both the Input and Output, it resolves the hum issues that are often symptomatic of ground loop problems. This simple yet effective tool is a testament to the MLI1's commitment to delivering clean, uninterrupted signals for live performances, broadcast settings, and studio recordings.

Durability is not an afterthought with the MLI1. Encased in a robust 14-gauge steel chassis, it is built like a fortress, ready to face the rigors of the road. This roadworthy construction ensures that the internal components, including connections, switches, and solder joints, are shielded against the wear and tear of touring. The MLI1's sturdy exterior guarantees that it will deliver quiet, reliable performance time and time again.

Whether you're a touring musician, a broadcast engineer, or a studio technician, the Samson MLI1 Mono Passive Isolation Box is an indispensable tool in your audio arsenal. It offers a professional-grade solution to common signal issues while providing the durability needed for consistent use in any professional audio setting.
