The title of the final report title is " The Design Of Hearing Device Of Long Distance By Using Multi Stage Amplifier And Low Pass Filter (Multi Stage Amplifier)". In the final report, the author aims to study the workings of the operational amplifier circuit and amplifier class B (Push Pull) on the circuit this hearing devices. In designing this tool, used some circuits that regulator circuit, pre-amplifiers, filters, and amplifiers class B (push-pull). The first most important stage in the design process is to make the block diagram of the circuit, making the circuit paths, and choose the components that fit the needs and then get the results and discussion. This tool requires an input voltage of 14.4 volts, then a small microphone captures audio frequency signals and transform them into electrical signals, entered into a series of pre-amplifier IC LM741 reinforced with two levels, further strengthened by a string of class B amplifier as voltage amplifier, then in filter by filter circuit LPF order to four, the final amplifier and the output of the audio output (sound) with a frequency range of 1 Hz - 1 KHz. Key word : Op-amp IC LM 741, amplifier push pull , pre-amplifier, LPF.
