The Radial Engineering STUDIO-Q is a talk-back interface with a built-in microphone. The STUDIO-Q features a simple cue switch that turns on a built-in microphone or the 'producer' mic XLR input. Once depressed, the signal is routed to the studio headphone system while it automatically shunts the program to the desired level. The program signal path is balanced for easy integration with any console with fully variable level control on the front panel. When the band is full-on, a remote output may be used to send a dry contact to a beacon and attract attention. This can also be set with DC power to accommodate a LED beacon.
