linjenivå

Linjenivå is a Swedish term that translates to "line level" in English, referring to a standard signal level used in audio equipment. It represents the strength of an audio signal that is typically produced by source devices such as CD players, audio interfaces, and preamplifiers, and that is sent to input devices like amplifiers or mixers. The standard nominal level for line level is typically +4 dBu (which is approximately 1.23 volts RMS) for professional audio equipment and -10 dBV (approximately 0.316 volts RMS) for consumer-grade equipment.

Understanding line level is crucial for proper audio signal routing and gain staging. If a signal is too low, it may be overwhelmed by noise when amplified. Conversely, if a signal is too high, it can cause distortion or clipping in the receiving equipment. Matching the output line level of one device to the input line level of another ensures optimal signal integrity and sound quality. While "line level" is a general term, specific devices will often have their own specifications for output and input impedance, which should also be considered for optimal performance.
