POWER AMPLIFIER & SPEAKER

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 off when not required. The outputs are overload and short-circuit protected.
