Allmetal, impact resistant design. Ruler flat frequency response from 10Hz-35kHz. Flexible connectivity with 1/4" and XLR input and output connections. Samson STL transformer isolates input and output signals. Mono line isolation box eliminates hum and buzz caused by ground loops. The Samson MLI1 is a line level passive isolation box designed to remove hum and buzz caused by ground loops, as well as to convert unbalanced signals to balanced signals for long cable runs. Combining premium sound circuitry with durable, roadworthy construction, the MLI1 provides highquality signal connection solutions for live, broadcast and studio applications. The MLI1 features Samson's STL transformer that delivers an extended, ruler flat frequency response from 10Hz-35kHz (±0.2dB) with ultralow distortion. The transformer isolates the input signal from the output signal, removing any DC noise. The Ground Lift switch disconnects the ground from the Input and Output connections which eliminates hum caused by ground loops.
