ast 1 00q & ast110trq direct drive transducer operation : direct drive t ransducer devices do not have any included dc circuitry, so the user mus t apply a sine or square wave with the appropriate rated frequency. a square wave will typically re sult in more sound level than a sine wave . the higher the peak - to - peak voltage applied (up to the maximum rated voltage), the hig her the resulting sound level. frequency response :
