pt - 1240pq & pt - 1240peq 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 result in more sound level than a sine wave. the higher the peak - to - peak voltage applied (up to the maximum rated voltage), the higher the resulting sound level. frequency response :
