What term is used for the standard level of an analog audio output from consumer devices?

• A. Peak level
• B. Line level
• C. Digital level
• D. Reference level

Answer: (B)

Line level is the standard nominal analog output level that consumer audio gear uses to drive other equipment’s line inputs. It represents a typical operating range, ensuring compatible gain structure across devices. For consumer gear, this is usually around -10 dBV (about 0.316 V RMS), while professional equipment commonly uses +4 dBu (about 1.23 V RMS). This differs from peak level, which is about the maximum instantaneous amplitude, and from mic level or instrument level, which are much lower and require preamps or different interfacing. Digital level refers to the signal in the digital domain, not the analog output standard.
