Larry Janus is no stranger to broadcast engineering, but his passion is excellent design of vacuum tube based audio circuits, and then controlling their functions using modern control electronics via WiFi. This passion leads to a clever integration of a tube-based mic pre-amp, fully remote controlled using a phone app over WiFi. This arrangement gives rise to some interesting and convenient possibilities for stage-placed mic pre-amps with remote control. Larry Janus joins us from his well-equipped home lab in Florida.
