The Pro Co SAS1 Sports Announcer’s Switch is a simple, rugged, desktop push-to-talk microphone switch designed specifically for sporting event announcers. This microphone signal actuating device offers clean reliable performance with any balanced or floating low-impedance (150 ohm nominal) microphone or signal source. SAS1 is designed for use with either condenser-type or dynamic microphones. The SAS1 is ideally suited for use in sports event announcing applications but is equally suitable for any application where a desktop push-to-talk device is required. The SAS1 is backed by Pro Co’s five-year, any excuse - even abuse warranty.
