Measured on IEC baffle using Bruel & Kjaer 3144 model microphone.
For correct readings, measurement should be conducted after a sufficient run-in period,
at minimum temperature of 21º C (69.8º F), for both drive unit and measurement environment.
Morel operate policy of continuous product design improvement, consequently specifications are subject to alteration without prior notice.
