Willdife Acoustics SMM-A2 Ultrasonic Microphone for SM3/SM3BAT and SM4 + cable from 3M
€257.50 tax excl.
The SMM-A2 is a new highly sensitive microphone, optimized to make better recordings than any previous model.
Weather-resistant, the SMM-A2 microphone has a differential output that significantly reduces noise from electromagnetic sources.
The improvements made to this microphone have increased the signals coming from the cables (up to 100 meters), it also has a differential output that significantly reduces noise and interference from electromagnetic sources.
The end result is a higher quality recording, even when cables are passed along other cables, on metrology towers or wind turbines.
The omnidirectional SMM-A2 is ideal for unattended recording where the precise direction of bat activity is not known in advance, it can be used on SM3/SM3BAT and acoustic SM4.
Sold alone.
- Be careful, if the microphone is used with cables, to position it slightly or completely downwards (it is omnidirectional), so that water does not accumulate in the foam. Thus prioritize a high-level installation to point the microphone downwards.
- Always use protective foam.
- Make sure that the foam is not pushed against the microphone tip, there must be an 'air gap' between the end of the microphone and the foam.
- Do not handle the microphone if the foam pad is wet.
