MICROPHONE 248600 • Digital microphone for use with SpeedGate • D igital microphone for use with datalogging • A nalog microphone for use with Frederiksen timers • A nalog microphone for general sound experiments One unit – many applications The new microphone is tailored to its use by choosing among different cables. In itself, the microphone provides both a basic analog signal and a digital signal that goes high when the sound level exceeds a certain threshold. Lab activity: Studying the Speed of sound The sharp sound from a clapperboard passes two microphones with a given distance between them. The first microphone starts a timer and the second one stops it. For this lab activity, choose a cable (2 pcs.) depending on what timer you use: Frederiksen’s Electronic stopwatch 200260 uses DIN sockets for inputs. Use cable 248601. Frederiksen’s Electronic counter 200250 has DIN sockets as well as 6 mm jack sockets. In this case, you may use a cable 512560 as a less expensive alternative to the cable 248601. Frederiksen’s new SpeedGate 197570 uses modular connectors and connects to the microphone through a cable 197571. Each SpeedGate comes with one of these cables. Therefore, you will need only one more cable 197571 to connect both microphones. Pasco’s dataloggers and their digital adapter uses 6 mm jack plugs. Use cable 512560. Lab activity: studying waveforms For lab activities with sound where the waveform is to be studied, use the microphone’s analog output. With an oscilloscope, use a battery box 251560 and the cable 248601 Plug the microphone directly into Pasco interface with an analog DIN input through the cable 248602.
