The DBX Driverack RTA Condenser Microphone is a omni-directional, flat frequency, measurement microphone designed for use with DBX"s Driverack systems. The Driverack RTA microphone lets you Pink and optimize the EQ settings of any room through the use of the Auto EQ in the Driverack Wizard setup assistant. Even though the Driverack RTA Condenser Microphone is designed to be used with the Driverack systems, this is still a condenser microphone and works great on acoustic guitars, pianos, drums or just as a room microphone.
