To be connected to any kind of standard audio amplifier (capable of 2-8ohm). Cannot be used for 100V or 70V transmissions! An operation with a speaker protection module DSP-1 which is adjusted accordingly is recommended. It will protect the UWS-100 against overload, because the volume level of the underwater speaker cannot be heard outside the water and above the water surface area.
The radiation of both the sound and the volume is different underwater than it is in the air. Thus, it is recommended to try out for the ideal position of the underwater speakers in order to obtain perfect results. Basically, the sound of the systems is always to be evaluated underwater. There is practically no sound to be heard above the water surface area. For greater capacities or for achieving higher volume levels, the application of several underwater speakers is recommended which should generally be distributed evenly. One single underwater speaker is able to sufficiently radiate the sound in about 25m3 of water.
