ETS KMSP-1 Microphone Mute Key Switch with LED Status Indicator
The ETS KMSP-1 is a flush mount, stainless steel, keyed mute switch with an LED status indicator for use with ETS SM1 series microphones. The KMSP-1 is typically used in interview or interrogation rooms when it is required that the microphone be turned off on occasion.
The KMSP-1 can be located anywhere along the cable run between the microphone and head end equipment. It connects directly to ETS switchers / mixers / amplifiers or it can be used with one of our many interface products to make fast and clean connections to DVRs or remote monitoring equipment.
Additional features include euro-style connectors, 12VDC power use, and it can mount flush to a single gang electrical box.
