Description

The SoundTrap ST440 HF is a four channel digital acoustic recorder for ocean acoustic research. Its ability to record synchronous audio on four channels make it ideal for creating arrays for sound localisation, and its small size enbles integration into tow bodies for linear transect surveys.

Key features:

• Selectable 1 to 4 channel recording
• 384 kHz sampling rate
• Bandwidth 20 Hz – 150 kHz 
• Up to 2 TB of removable data storage
• Up to 8 days continuous 4 channel recording

• 200m depth rating
• Short term recorder – suitable for up to 3 month deployments 

The ST440 HF records signals from up to four hydrophones connected via four wet connectors on the base of the recorder. The hydrophones are the pre-amplified type, and can be on long cables to enable array spacing’s of several meters. Suitable hydrophones can be specified with various gain and bandwidth options.

Output files are in the industry standard WAV or FLAC format. The included software offers flexible deployment options for channel selection, sample rate, delayed start and duty cycle.

Price includes 256GB of memory, remote, cables and software.

The ST440 is desgined for use with SoundTrap HP2 or HTI hydrophones, see the datasheet for details.

The ST440 uses 18650 lithium ion batteries. Batteries are are not supplied with the recorders due to shipping restrictions. They are available in most countries and we recommend purchasing  in the country in which the recorders are to be used to avoid air transport issues. A battery charger will also be required. We recommend the XTAR VC4 or similar.
