TB1

Common name: Studio Projects TB1

Production Status: In production

The TB1 is a vacuum tube (valve) microphone incorporating the philosophy that the best microphones use. 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 output is transformer balanced. The TB1 is powered by a dedicated AC power supply (DJ8) and 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. Includes Foam windscreen, microphone clip, power supply, microphone cable and aluminium case.
