The LX-2 performs the dual functions of splitting a line level audio signal and providing level attenuation where necessary. A premium Jensen transformer inside provides exceptional frequency response and phase coherency to ensure that the highest audio quality is maintained, while isolating the two outputs from each other to eliminate hum and buzz from ground loops. For situations where a level adjustment is required, the trim control on the LX-2 allows you to attenuate overly hot signals. This gives you the ability to drive your mic preamps hard to achieve coloration, while trimming the level at the LX-2 to avoid clipping the inputs of your recording interface. This trim control is activated by a recessed ‘set & forget’ switch; if attenuation is not needed, simply disengage this switch to prevent accidental and unwanted level adjustments.
