Logic Pro Certification CRAS Practice Test 2025 – Comprehensive Exam Prep

To manually adjust the make-up gain of a compressor, turning the auto gain off is necessary. When the auto gain function is engaged, the compressor automatically adjusts the output gain based on the amount of compression applied, which prevents the user from making manual adjustments to the make-up gain. By disabling this feature, you gain full control over the output level, allowing you to manually fine-tune the make-up gain to achieve the desired loudness and tonal balance in your mix.

In contrast, enabling the auto gain function would negate the need for manual adjustments since the system would handle make-up gain automatically. Setting the threshold to zero does not directly relate to manually adjusting make-up gain; rather, it influences when the compressor starts to process the signal. Using the output gain knob might seem plausible, but if auto gain is enabled, adjustments made here will not reflect any manual effort since the compressor will adjust the output automatically. Therefore, turning off the auto gain function is a critical step for manual control over the make-up gain.
