Description
The Dual Amplifier for AC, DC and Audio Signal, also known as the IEC Dual Amplifier or laboratory signal amplifier, is designed for practical signal amplification in physics and electronics teaching laboratories. The unit provides two independent amplifiers for different classroom and laboratory applications. The first amplifier is a wide bandwidth AC amplifier with a frequency range of 10 Hz to 10 MHz and a fixed gain of 100. This amplifier has no additional controls relating to its operation.
The second amplifier is an audio frequency amplifier operating from DC to 10 kHz, with selectable DC or AC operation and gain up to 500 across 6 switchable steps. The selectable gain values are listed as 10, 20, 50, 100, 200 and 500, allowing the audio amplifier output to be adjusted for different signals and classroom demonstrations. In DC mode, the audio amplifier includes an offset control to compensate for drift by permitting zero output when the input is zero. This offset function is not required when the unit is used as an AC amplifier.
Either amplifier can be switched on from the front panel, with the centre position of the switch acting as OFF. An LED indicates which amplifier is active. Both amplifiers use a common 9 V supply from a rack of 6 × AA batteries, accessible through the rear panel. The LED flashes when the batteries require replacement. A loudspeaker is fitted to one end panel and can be switched from the front panel, supporting audio signal demonstrations and classroom observation. All connections are by 4 mm sockets, with two sockets provided for input and two sockets provided for output.
Users should confirm signal level, frequency range, gain setting, input and output connections, battery condition and compatible experiment procedure before use. Use only with compatible low-voltage educational circuits. Do not connect the amplifier to mains voltage, high-voltage circuits, high-current sources or unknown electrical equipment. Avoid excessive speaker volume, incorrect polarity and unsuitable input signals, as these may damage the amplifier, connected equipment or hearing comfort during demonstrations.
This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the selected IEC Dual Amplifier only. Batteries, signal generator, oscilloscope, microphone, speaker leads, meters, worksheets, PPE and additional electronics accessories are not included unless specified separately.
LabChoice Australia supplies Dual Amplifiers and electronics teaching apparatus for school science laboratories, university teaching laboratories and educational facilities requiring practical signal amplification equipment.
