What does an opto (optical) compressor's response characteristic tend to be?
Answer: Smooth and program-dependent with a slower, musical release
Opto compressors use a light-cell circuit that yields a smooth, gentle, level-dependent response.
What is gain reduction metering showing you?
Answer: How many dB the compressor is currently turning down the signal
The gain reduction meter displays the amount of attenuation the compressor is applying in real time.
Setting too fast an attack on a drum bus typically does what?
Answer: Clamps the transient and softens the punch
A fast attack catches the initial transient, which can dull the snap and punch of drums.
What is the purpose of a VCA compressor in mix work?
Answer: Clean, flexible, precise control suited to bus and master compression
VCA compressors offer versatile, accurate gain control, making them popular on mix buses like the SSL.
Why is bit depth relevant to dynamic range?
Answer: Higher bit depth provides a larger possible dynamic range and lower noise floor
Each added bit increases theoretical dynamic range by about 6 dB, with 24-bit offering far more than 16-bit.
What does 'auto release' on a compressor do?
Answer: Adapts the release time to the program material automatically
Auto release lets the compressor adjust release timing based on the incoming signal for more natural results.
What is the threshold on a compressor?
Answer: The level above which gain reduction begins
Signal must rise above the threshold before the compressor starts reducing gain.
