It features a 24Volt phantom power supply to drive an active hydrophone equipped with the standard 3pole XLR connector. High signal output due to a high supply voltage of 4 pcs 9 volt square batteries. The amplifier may also be powered from the included mains powered wall plug AC adaptor. Frequency range from 10Hz to 50kHz. plus a very high gain of 70dB. High and Low pass filters for emphasizing the listening frequency range. A mixing function to connect with a monitor amplifier or a set of headphones.

This unit is compatible with most any type of professional studio recording and reproduction equipment. We recommend the ZOOM type H4 handheld digital recorder to supplement this listening amplifier for recordings and documentation. This device will record the audible range 20hz to 20kHz. For the wider bandwidth of 10Hz to 50kHz we recommend the audio interface AD converter adaptors from ZOOM. They are designed to be connected to a computer with USB interface for recording. Types in qestion could be the following units which offers up to 192khz of sampling rate : ZOOM UAC-2 for Windows USB ZOOM TAC-2 for MAC Thunderbolt ZOOM F8 for 8 channel high quality multitrack recordings.
