The Audible Illusions L3 preamplifier’s acquire refers back to the diploma to which it amplifies an audio sign. This specification, expressed in decibels (dB), signifies the voltage enhance the preamplifier applies to an incoming sign earlier than sending it to the facility amplifier. The next acquire worth leads to a louder output for a given enter sign. As an example, a preamplifier with a acquire of 20dB will amplify a 1mV enter sign to 10mV.
Applicable acquire is essential for optimum system efficiency. Ample acquire ensures the facility amplifier receives an ample sign degree to succeed in its full energy output with out introducing extreme noise. Too little acquire could lead to a weak or quiet sound, whereas an excessive amount of acquire can result in distortion and clipping. The L3 preamplifier’s design doubtless incorporates a acquire stage rigorously chosen to steadiness sign amplification with noise ground minimization and harmonic distortion. Understanding a preamplifiers sign amplification properties is essential in accurately matching it with different elements in an audio chain.
