To connect the Aquarian PA4 Hydrophone Buffer/Preamp to your microphone preamplifier, you will need to follow these steps:
1. Determine the power source: The PA4 can be powered either by phantom power from your microphone preamplifier or by an external 6 ~ 12 volt DC power source.
2. Set the gain: The PA4's gain can be adjusted from 6 to 56dB by jumper configuration and output wiring. Refer to the user manual for specific instructions on how to set the gain according to your requirements.
3. Choose the output type: The PA4 can provide either differential (balanced) or single-ended output. Select the output type that is compatible with your microphone preamplifier.
4. Connect the PA4 to your microphone preamplifier: Use appropriate cables to connect the output of the PA4 to the input of your microphone preamplifier. Ensure that the connections are secure and properly grounded.
5. Power on the PA4 and microphone preamplifier: If using phantom power, make sure it is enabled on your microphone preamplifier. If using external DC power, ensure that the power source is connected and providing the correct voltage.
6. Test and adjust: Once everything is connected, test the setup by recording or monitoring the audio signal. Adjust the gain and other settings as needed to achieve the desired sound quality.
Note: It is important to keep the PA4 and all connectors and electrical components as dry as possible, especially when working in corrosive environments such as seawater or chlorinated water. The PA4 is not waterproof.
