The ProCo Model CDPM "Power Mute" Selectable Microphone Muting Switch is an active microphone signal muting device that offers clean reliable performance with any balanced or floating low-impedance (150 ohm nominal) microphone or signal source. The Power Mute may be set to operate as a momentary press-to-mute, momentary press-to-talk, or latching (mic on/mic off) microphone muting switch. The Power Mute is ideally suited for use in broadcast, disc jockey, sports announcing, boardroom, and live entertainment applications when the need to mute a microphone output is required.
Dip switches are used to select the desired Power Mute mode of operation from momentary push-to-talk, momentary push-to-mute to latching. To change the condition of the microphone signal, the user simply depresses and actuates the switch. In momentary mode, the condition will change when the switch is pressed and will revert to its original condition once the switch has been released. In latching mode, the signal condition will change when the switch is pressed and actuated. It will remain in that condition until the switch is depressed and actuated again. The switch on the Power Mute may either be actuated by hand or the unit may be used as a footswitch.
The status indicator light displays the condition of the microphone signal regardless of the selected mode of operation. When the light shows green, it indicates that the microphone is “on”. Red indicates that the microphone is muted or “off”. Connections between the Power Mute 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. A mini toggle ON/OFF power switch is provided and the unit features a tool-free-access battery compartment. The Power Mute may be operated with a 9V battery or with the 9V AC power supply provided. Dip switches are located within the battery compartment. The Power Mute 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.
