For more information and a copy of the Declaration of
Conformity (EN 45014), see the Song Meter User Manual.
- Physical Specifications
- Dimensions: 8.4" x 7.1" x 2.4"
- Weight: 2.8 pounds with batteries (SM1, SM1-M); 1.6 pounds w/o batteries (SM1P, SM1-MP)
- Enclosure: IP 66/67, NEMA-4 (weatherproof)
- Operating temperature: -4ºF to +158ºF; -20ºC to +70ºC
- Audio Specifications
- Built-in stereo omnidirectional microphones (SM1 and SM1-P only)
- Sensitivity: -35 +/- 4dB (0dB = 1V/pa @ 1KHz)
- Frequency response: 20Hz - 20,000Hz
- Signal-to-Noise Ratio: > 62dB
- High-pass filter: Optional 160Hz high-pass filter can be enabled per
channel.
- Mic. amplification: Programmable -1.5dB to +45.0dB in 1.5dB increments, per channel.
- Sample rates: 4000, 8000, 16000, 22050, 24000, 32000, 44100, and 48000 samples/second
- Digital format: 16-bit PCM (.wav) or Wildlife Acoustics lossless compression format (.wac)
- Storage
- SD/MMC flash card slots: 2
- Compatibility: SD, SDHC, MMC, MMC Plus (see Flash Card Compatibility for details)
- 16GB SDHC cards are available from vendors today for a total of 32GB
capacity with more expected as new SDHC and MMC Plus cards become
available
- Capacity is typically doubled when using compression
- Power
- Batteries: (SM1 and SM1-M only) 4 "D" batteries (Alkaline or NiMH)
- External power supply: (SM1-P and SM1-MP only) 6-12V DC, 500mA (models shipped before March 31, 2008 are only rated to 6V).
- Consumption: 140 +/- 10 mA during recording, < 1 mA when
sleeping between recordings. Add 10mA for SM1-P and SM1-MP models when recording and sleeping. Add 10mA for compression at high sample rates.
- Recording time: 79 +/- 4 hours assuming 11,000 mAh NiMH batteries in
ideal conditions, or over 100 hours in most cases with fresh Alkaline
batteries
- Future Expansion
- Field upgradeable via SD/MMC cards
- 400 MIPS DSP, 8MB SDRAM, 4MB Flash available for future signal
processing applications such as detection, classification and
compression.
