8300 MkII Sound Reception System
5.9.3 Audio Settings
The audio settings of the P-8300 MkII display unit allows a user to adjust the signal-to-noise ratio required prior to a foghorn
being detected. The default value is 2.25, calibrated to handle a foghorn where the bulk of the energy lies between 700-2100
Hz from 0.5 nautical miles when a horn creates a 111 dB SPL sound level.
The signal-to-noise ratio configuration ranges from 2 to 6. The higher the values the stricter the P-8300 MkII display unit will be
in detecting foghorns. Lower values will detect more foghorns, but are more susceptible to false detections.
To configure the signal-to-noise ratio:
1. Use the slider or manually type in a value.
2. Click the
Save settings
button.
