StageDirect™ Specifications

The Radial StageDirect is an active direct box that combines instrument switching with a class-A input buffer and state-of-the-art electronics to perform impedance matching and balancing. This results in a near-perfect frequency response from 20Hz to 20kHz with less than 1dB deviation. The StageDirect employs an isolated instrument throughput that helps eliminate hum and buzz caused by ground loops. This also enables the StageDirect to be used with either phantom power or an external 15VDC supply. The StageDirect is unique in that it may be muted using a local footswitch or remotely controlled via an external momentary switch.
