The Audible Illusions L3 preamplifier’s gain refers to the degree to which it amplifies an audio signal. This specification, expressed in decibels (dB), indicates the voltage increase the preamplifier applies to an incoming signal before sending it to the power amplifier. A higher gain value results in a louder output for a given input signal. For instance, a preamplifier with a gain of 20dB will amplify a 1mV input signal to 10mV.
Appropriate gain is crucial for optimal system performance. Sufficient gain ensures the power amplifier receives an adequate signal level to reach its full power output without introducing excessive noise. Too little gain may result in a weak or quiet sound, while too much gain can lead to distortion and clipping. The L3 preamplifier’s design likely incorporates a gain stage carefully selected to balance signal amplification with noise floor minimization and harmonic distortion. Understanding a preamplifiers signal amplification properties is important in correctly matching it with other components in an audio chain.
