The Power Amplifier is a very useful classroom resource that allows students to amplify and listen to a variety of audio sources ranging from microphones and audio devices with a 3.5mm headphone socket, to signal generators equipped with 4mm socket outputs
The amplifier is particularly suitable for driving Vibration Generators and Rubens' tubes when a power signal generator is not available
The amplifier has an internal 10W speaker that can be switched offWhen not required
The outputs are overload and short‐circuit protected
