Amplifiers — Set the amp output level, select a signal crest factor, loudspeaker sensitivity, and distance using sliders and selectors.

Read out the resulting SPL level, see the amplifier output voltage, and also the Watts to the loudspeaker, dB Reference Sensitivity, and the Sine Burst Rating.

Uses generic devices now, soon it will support selecting specific amplifiers and loudspeakers from manufacturers participating in our sponsorship program.
