Studio Projects TB1 Vacuum Tube Condenser Microphone Overview:

The TB1 is a vacuum tube (valve) microphone incorporating the philosophy that the best microphones use high quality, yet minimal components, along with hand selected tubes. Using the finest available materials to build the best possible capsule, the Studio Projects TB1 achieves this philosophy and more. Valve microphones have long been appreciated by studio engineers for their warm yet natural sound. The Studio Projects TB1 provides audiophile sound engineers with the classic vacuum tube design combined with today’s better quality components.

The circuit design of the TB1 uses as few components as necessary to prevent added noise and coloration. A special hand selected 6072 “dual triode” vacuum tube is used to ensure consistency. The TB1 is powered by a dedicated AC power supply (DJ8). The TB1 provides the warm transparent sound associated with an expensive quality vacuum tube preamplifier. This perceived sound characteristic has been very popular and sought after for vocals and instrumentation soloists.
