Common causes of short circuits in a simple audio amplifier include faulty components such as damaged transistors, capacitors, or resistors that can create unintended pathways for current. Poor solder joints or loose connections may also lead to short circuits, as they can allow wires to touch each other inappropriately. Additionally, overheating due to excessive power draw or incorrect power supply voltage can damage parts and result in shorts. Lastly, external factors like moisture or debris can compromise insulation and cause shorts in the circuit.
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.
The transistor is the circuit component that typically acts as a switch or amplifier. In switching applications, it can control the flow of current through a circuit, while in amplification applications, it increases the strength of weak electrical signals. Transistors are fundamental in modern electronics, enabling various functions in devices ranging from computers to audio equipment.
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.

A sound (audio) amplifier works by making a larger copy, or series of copies, of a weak signal.
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.

Yes. And it will also present the wrong load impedance (mismatch) at the output of the audio amplifier, with the possibility of damage to the amplifier.
In audio look at an amplifier. It will be always a voltage amplifier.
I've seen a Logic chip, 2 input quad NAND gate IC, that was set up as a Audio amplifier circuit.

A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-

An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
