A stereo amplifier picks up an analog signal and outputs it as a stereo signal. But how does it actually work? The stereo amplifier receives less than it outputs. To obtain more energy, it is important that the stereo amplifier uses another energy source to magnify the signal. A stereo amplifier is used together with a stereo system. Such amplifiers are available in consumer electronics stores and online trading platforms.

Audio & Hifi: Stereo amplifier Video Guide
The active part of a stereo amplifier is a transistor. This copies the incoming audio signal from an audio component and fills it with another energy source. With stereo amplifiers in vehicles, the transistor takes the energy from the car battery. With a home stereo system or a home cinema system, the mains supply is responsible for this, to which the amplifier is connected by means of a mains adapter. Amplifiers for stereo systems work with both direct and alternating current.
The incoming audio signal itself cannot be magnified, so it remains in its regular state. The stereo amplifier uses the signal (image) of what is received, like a copier in a magnified copy, and converts its copy into a larger signal. Without an amplifier the incoming signal would be the same as the outgoing signal. In order to produce a particularly powerful sound, a stereo system is dependent on an amplifier. In the past, all components of a hi-fi system had to be connected to each other via cables. This was by no means a problem due to the appropriate plugs, but over time more and more manufacturers are opting for wireless connections. It is possible to transmit the incoming signal via WLan (Wifi) or Bluetooth. This allows amplifiers to be set up separately from the stereo system. Stereo amplifiers can be operated using the remote control supplied. These have been standard for decades. The function is entered using the buttons on the remote control. For movies such as music, the amplifier can be individually adjusted to regulate distorted sound. Not all audio inputs are equal or weak and require the same gain to produce a consistent sound.
Yamaha is committed to the highest quality in building electrical components for sound reproduction. This also applies to stereo amplifiers with digital sound. Gold plated input sockets are used for better transmission of the audio sounds and the loudspeakers should also have gold plated plugs, as the material conducts much better and more evenly than silver plated plugs. The A-S501 with D/A converter offers coaxial connections, digital inputs for audio from Blue Ray players and/or TV sets and a connection for a Bluetooth wireless adapter. Accessories may be required to use the amplifier. For example, to increase the distance between loudspeakers and amplifier. An audio cable with gold-plated “banana plugs” is used for this purpose. The Bluetooth adapter enables the transmission of audio files via an external electronic device that can receive and transmit the Bluetooth signal. Theoretically it is therefore possible to completely dispense with other stereo system elements, since the home laptop or computer functions as a transmitter of audio files. The PC is connected to the Bluetooth adapter of the stereo amplifier. By playing the audio file in the PC, the signal is sent to the amplifier, which copies it and produces a new larger signal, which the stereo amplifier outputs through the speakers. It is important that the amplifier is capable of compensating for hearing loss by independently controlling both higher and lower frequencies. This results in an even frequency, which is especially important for films. Because the audio signals are stored on DVD or Blue-Ray in different frequencies. Who doesn’t know this when a loud signal suddenly drowned out the previous dialogues in an action scene? Impractical if the film is watched from the evening while the children sleep in the children’s room next door. Such a control prevents the frequency from fluctuating. Another major supplier of stereo amplifiers is Pioneer. The manufacturer also relies on quality elements in its components to produce a very good sound. Pioneer stands out from the competition in terms of colour, which also offers stereo amplifiers in silver or brushed chrome. This brings variety into the home living room. Stereo amplifiers are not only available for stereo systems or home cinema systems, but also for the telephone to amplify the ring tone. The “CL11” device from Geemarc is also equipped with a red signal lamp and is ideal for the elderly and hearing-impaired to make sure they don’t miss a call in the future.
