Product Information: ..
The microphone box is a universal, dual-channel amplifier for electret microphones with a band width of 10 Hz to 40 kHz. Both channels (A und B) can be switched between Signal, Level and Trigger modes. The sensitivity of the pre-amp is adjustable and allows measuring instruments and oscilloscopes to be connected directly. The threshold for the trigger is also adjustable. The microphone box is particularly suitable for use with long and short microphone probes and the microsecond counter in order to carry out experiments on the speed of sound.
