Acoustic Module AM 661S + 100m long cable on hand reel (P/N 9300102): Use of
AM661S Acoustic module is recommended in poor acoustic propagation conditions,
in noisy environment or when long cables are required between TT801 cabinet and
Dunking Transducer. AM661S use is recommended when the sound velocity profile
presents strong gradients near the surface (as it exists in the tropical and equatorial
waters for example). Long cable helps also in reducing the impact of vessel noise
environment by getting the AM661S as far away as possible from thrusters or
propellers.

This feature helps to give an audio indication of sonar signal reception. Acoustic
frequencies received by the dunking transducer are converted into 0-8 kHz audio
frequencies. Headphones enable to listen to the acoustic signals in the seawater
specifically the CAF Acknowledgements pulses or the PFR pulses when the Pinger mode
is activated.
The TT801 front panel is described in Figure 7.
