The Pro Co Model CDSO "Sign Off" Latching Microphone Muting Switch is a simple microphone signal muting device that offers clean reliable performance with any balanced or floating low-impedance (150 ohm nominal) microphone or signal source. The Sign Off is ideally suited for use in broadcast, disc jockey, sports announcing, boardroom, and live entertainment applications when the need to temporarily mute a microphone output is required.
To mute the microphone signal, the user simply depresses and actuates the switch. The Sign Off is a latching muting switch, so the signal will remain muted until the switch is depressed and actuated again. The switch on the Sign Off may either be actuated by hand or the unit may be used as a footswitch.
Connections between the Sign Off and the microphone or signal source and to the sound system are made with standard microphone cables.
A female XLR-type connector is provided for Mic Input and a Male XLR-type connector is provided for Direct Out. The Sign Off enclosure is formed of a 16-gauge steel top and a rugged 11-gauge, black epoxy painted steel base. Steel provides excellent magnetic shielding from 60Hz AC hum fields. All control and connector function graphics are identified on a textured polycarbonate overlay. The enclosure is with (4) non-conductive, anti-skid feet on the base of the unit. Top-quality connectors and switches provide trouble-free service even in abusive situations such as remote broadcast and recording operations.
