* The maximum recommended amplifier power rating will ensure proper system headroom to
allow for occasional peaks. We do not recommend sustained operation at these maximum
power levels.

†

The Peak Dynamic Power is measured by recording the highest center-to-peak voltage

measured across the output of a resistive load equal to minimum impedance of the transducer,
using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.
