Available Power Gain refers to the ratio of the available power output of an amplifier to the input power. It measures how effectively an amplifier increases the power from its input to its output. This gain is equivalent to the power gain only when the amplifier’s output is properly matchedContinue Reading

Available Power Efficiency refers to the ratio of electrical power available at the terminals of an electroacoustic transducer (such as a loudspeaker or microphone) to the acoustical power output of that transducer. This efficiency measure reflects how effectively the electrical power is converted into acoustic power and should be consistentContinue Reading

Auto-reverse is a feature found on some cassette players and other tape-based audio devices that allows for continuous playback of a cassette tape by automatically reversing the tape to play the other side once one side is finished. Here’s a detailed look at how it works and its applications: HowContinue Reading

Automatic Volume Expansion Definition: Automatic Volume Expansion is a process used to increase the dynamic range of audio signals by automatically adjusting the lower levels while keeping the peak levels constant. This technique helps to counteract the loss of dynamic range that may occur during recording, mixing, or transmission. KeyContinue Reading

Automatic Volume Control (AVC) Definition: Automatic Volume Control (AVC) is a technology used in audio systems, including radios and high-fidelity reproduction systems, to automatically adjust and regulate the sound volume. This can involve altering the contrast (dynamics) of sound during reproduction to maintain a consistent listening experience. Key Features andContinue Reading

Automatic Volume Compression Definition: Automatic Volume Compression is a process used in audio engineering to reduce the dynamic range of a signal, specifically targeting sounds that exhibit wide variations in volume, such as orchestral music. This reduction is essential for recording or broadcasting to ensure that the audio remains withinContinue Reading

Automatic Quiet Gain Control Definition: Automatic Quiet Gain Control is a system that combines automatic gain control (AGC) with muting to manage audio signals. This integrated approach is designed to maintain a consistent audio level while minimizing unwanted noise or interruptions. Key Features Operation Applications Advantages Summary Automatic Quiet GainContinue Reading

Automatic Gain Control (AGC) Definition: Automatic Gain Control (AGC) is a system used in amplifiers and receivers to automatically adjust the gain of the signal being processed. This adjustment compensates for variations in input signal strength, ensuring a consistent and uniform output level despite fluctuations in the incoming signal. KeyContinue Reading
