ACCESSORIES
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.
SM4BAT Armor
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.
Song Meter Surge Protector
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.
