Shure's PG27 microphone represents the new breed of USB-based active mics, drawing both power and connectivity from a built-in USB interface. Many of the functions of the mixing console have been transferred onto the microphone itself – you'll find volume and gain controls, a -20db cut for noisy sources and, most importantly, on-mic live monitoring, which cuts out the usual latency that software monitoring suffers.
