SMM-U2 Ultrasonic Microphone
The SMM-U2 microphone's low noise and superior sensitivity results in recording bat calls at greater distances. The enclosure's innovative waterproof design includes a built-in mounting bracket that allows for a wide range of mounting options. The microphone includes a 5 meter cable, and can connect with cables up to 100m in length with no adverse effect on recording quality.
SMM-U1 Ultrasonic Microphone
For legacy projects that require year-to-year microphone performance continuity, the SMM-U1 microphone can be used in place of the more advanced SMM-U2.
Song Meter SM4BAT GPS Option
For researchers who have large geographic areas to cover, the GPS option is a valuable, time-saving tool. When deploying multiple recorders, use a single GPS accessory to set and synchronize the date, time and location settings on/between each of your recorders. For mobile transects, connect the GPS accessory to log recording locations and transect path.
SM3/SM4 Power Cable
The SM3/SM4 Power Cable allows your Song Meters to run on external battery power, or a complete solar panel charging system. Simply plug the cable into the recorder's power connector and connect the other end to the battery system using the included spade or ring terminals. Song Meters will handle external power sources from 4.5 to 17V DC and is protected against accidental reverse voltage.
This lock will ensure your recorder's cover is secured. The unit features a brass body and cylinder to provide extra resistance to the elements. The marine grade lock is keyed alike, allowing multiple locks to open with the same key.
Weather Resistant Cable Lock
The adjustable locking mechanism holds the 6'/1.8m cable tight in any position for a secure fit. The unit features a weather resistant lock and vinyl coated 5/16"/8mm braided steel cable. Note: Locks are keyed differently.
Made of indestructible steel and coated in a durable powder epoxy finish, this custom-designed case is the best solution for preventing prying teeth and claws from damaging your SM4BAT. It provides visibility of the unit's LED light and also protects the unit's cable and power connections.
Ultrasonic Microphone Calibrator
Since ultrasound is beyond the range of human hearing, verifying proper system and microphone performance can be a challenge. The Ultrasonic Calibrator is designed to verify the sensitivity of our ultrasonic microphones as well as overall system performance.
Song Meter Surge Suppressor
The Song Meter Surge Suppressor protects SM4/SM4BAT recorders from power surges that could harm your recorders. This accessory should be used wherever microphones are mounted at elevation. Combine the Surge Suppressor with the SMM-U2 Grounding Bracket for added protection.
The suppressor is also compatible with the SM3 and SM3BAT.
SMM-U2 Grounding Bracket
If you’ve mounted your SMM-U2 ultrasonic microphone to a metrology tower, wind turbine or some mounting point at elevation, this custom-designed bracket protects the SMM-U2 from electrical surges or static discharge that could damage the microphone and recorder.
The grounding bracket is easy to attach and can be used with the Song Meter Surge Suppressor for maximum protection.
Use of the Song Meter Surge Suppressor with the grounding bracket is highly recommended.
NOTE: The SMM-U2 microphone not included.
SM4BAT FS RS-232 Monitoring Interface Cable
Designed for wind farm operators who need to know the status of their Song Meters, the SM4BAT FS RS-232 Status and Activity Monitoring Interface cable connects the SM4BAT FS to data loggers such as the Ammonit Meteo-40 and Campbell Scientific CR1000.
The SM4BAT FS can now respond to remote operator requests for cumulative numbers of bat passes and pulses detected, as well as timestamp, voltage, temperature, and flash card capacity.
