Song Meter SM4


Song Meter SM4 The smallest and lightest dual-channel weatherproof acoustic recorder available. The 4th generation Song Meter SM4 is a compact, weatherproof, dual-channel acoustic recorder capable of capturing large amounts of data from wildlife such as birds, frogs and aquatic life. The SM4 features two built-in microphones, innovative scheduling tools, large data storage, and low power consumption – a unique combination of features that provide the longest deployment times of any acoustic recorder available. Introducing a new generation of microphones. The SM4 features entirely new, built-in microphones that create higher quality recordings than those from all previous Song Meter recorders. Alternatively to the built-in microphones, the SM4 includes two microphone ports – giving you the flexibility to record additional data from a cabled microphone; a new SMM-A2 cabled acoustic microphone, and/or hydrophone. Two channels give you more recording flexibility. If you need to record two sources of audio at the same time, take advantage of the SM4 dual channel feature. Record in stereo or mono using the built-in microphones, or connect one or two cabled microphone/hydrophones. Adding additional runs of cable to the external microphone give you the ability to capture audio from far-off wildlife such as birds in the forest canopy, or frogs at a nearby pond. Capture months of acoustic data. The SM4 features new power circuitry that significantly increases deployment time over the SM3 – up to 400 hours of recording time using internal batteries. In Sleep Mode, between scheduled recordings, the SM4 uses almost no power, allowing it to remain idle for months – meaning longer deployments, and fewer trips into the field.
