About This Product
A weak signal from a generator or microphone cannot drive a speaker on its own, and the amplifier shows students how gain raises it to an audible level. It supports lessons on amplitude, loudness and energy conversion, and acts as the drive stage for resonance and sound-wave demonstrations.
Frequently Asked Questions
What should be connected to the output of the 5 W Amplifier?
A suitable loudspeaker. Make the connections with the amplifier switched off, check that the speaker rating suits the amplifier, then switch on and raise the output gradually.
