Microphones and Accessories for the Song Meter SM4

Song Meter SMM-A1 Acoustic Microphone SMM-A2 Acoustic Microphone

The cabled SMM-A2 acoustic microphone is an entirely new microphone, designed to create higher quality recordings than those from all previous microphone models. The microphone is weatherproof and can be deployed up to 100 meters away from the recorder.

Song Meter SM3 Hydrophone SM3-H1 Hydrophone

The SM4 recorder can also be used with an available hydrophone, the SM3/SM4 Hydrophone, for making underwater recordings. The hydrophone ships on a 20 meter cable and attaches to the same connectors as the cabled microphones.

An ultrasonic hydrophone to record dolphin echolocations is also available.

Song Meter SM3 Power CableSM3/SM4 Power Cable

The SM3/SM4 Power Cable allows the SM4 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. The SM4 will handle external power sources from 4.5 to 17V DC and is protected against accidental reverse voltage.

Padlock Marine-Grade Padlock

Chosen for the Song Meter SM4BAT, SM4, SM3BAT and SM3, 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.

Cable LockWeather Resistant Cable Lock

Specially selected for the Song Meter SM4BAT, SM4, SM3BAT and SM3, 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: Lock is keyed differently.

ArmorSM4/SM4BAT Armor

Created to keep prying teeth and claws away from your SM4 and SM4BAT, the custom designed Armor accessory is the best solution for maximum protection. Armor encases your Song Meter in an indestructible steel structure coated in a durable powder epoxy finish. It also protects cable and power connections, and provides visibility of the unit's LED light.
