The TC Level Pilot is a high-resolution analog stereo volume control that fits into any active loudspeaker setup quickly, and without need for an extra power supply. Using it as a level control after the DAW helps insure sonic integrity of the audio signal - Level Pilot works independently of the computer or audio interface, providing complete control over levels in all situations.

A quad core fully balanced extension cable eliminates messy cabling. A Bourns potentiometer offers high-resolution control. Level Pilot requires no power to operate and has both balanced and unbalanced compatibility. A “slip-free” rubberized base plate insures placement stability. Range: Off - 0 dB damping.

MSRP: $119
