Robbe Navy Sound Module RO8270

A sound module for model boats, containing six digitally stored original sounds. At any time a signal can be superimposed on the engine noise simultaneously, such as the Martins horn, foghorn, ship#92s bell, typhoon or destroyer siren, without interrupting the sound of the diesel engine.
The diesel engine sound varies according to the speed of the drive motor, and features start-up and run-down sound phases. The sound module features an integral 8-channel multi-switch decoder which is used to switch the individual sounds on and off.
A further two multi-switch switched channels are available for any purposes you wish, and can be used for direct control of auxiliary functions drawing up to 1 A (lights, anchor winch etc.). All inputs and outputs are protected against short-circuit and reverse polarity.
The sound module can be used with the earlier 6-channel and the current 8-channel robbe Multi-Switch modules, and also with other makes of similar unit. A powerful, high-volume amplifier stage provides distortion-free reproduction, and the volume is infinitely variable.
A Multi-Switch module must be installed in any robbe Futaba system transmitter to control the sound effects.
