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

The typical amplitude of audio signals output from DVD players is around 1 volt peak to peak. This voltage level is a standard reference in consumer electronics, particularly for line-level signals that interface between different audio devices, such as DVD players, amplifiers, and receivers.

Using 1 volt peak to peak ensures compatibility with various audio equipment, allowing for optimal performance without introducing distortion or noise. It also ensures that the signal level is adequate for it to be processed effectively by other devices while minimizing the risk of saturation or clipping in subsequent amplification stages.

In the context of audio systems, other choices like 0.5 volts, 2 volts, and 5 volts peak to peak are generally outside the typical range for consumer audio signals. A 0.5-volt signal might be too weak for proper signal processing, while 2 volts and 5 volts peak to peak are often too high for standard audio line-level inputs, potentially causing distortion or damage to sensitive audio circuitry. Thus, 1 volt peak to peak is widely accepted as the standard for integration with other audio equipment.
