What is the typical amplitude of audio signals from devices like DVD players for input to other equipment?

The typical amplitude of audio signals from devices such as DVD players is generally around 1 volt peak-to-peak. This standard level is commonly used in consumer audio electronics to ensure compatibility between devices, allowing for optimal performance without distortion or signal loss.

At this amplitude, the signal is strong enough to drive various types of audio equipment, including amplifiers and receivers, while minimizing noise and interference. This standardization facilitates the interchangeability of audio components across different brands and models, making it easier for consumers to connect equipment without significant issues.

Other amplitudes, such as 0.5 volts or 2 volts peak-to-peak, may be used in different contexts or equipment, but they are less common for standard audio outputs from consumer devices like DVD players. An amplitude of 5 volts peak-to-peak, while prevalent in some professional audio equipment, is typically higher than necessary for standard consumer use and could potentially lead to signal clipping or distortion if not managed properly.
