Hi Sirs,

Please provide guidance for my customer's DRC tuning with TAS2557 PPC3.
with the following configurations, DRC can take 3 seconds to take effect after turning on noise gate. Would you pls advise if there is missing or mistake?

Customer's test tone in tine and frequency domains:

Thank you and Best regards,

Hi Wayne,

I think there is actually not much to see form the test tone captures. Usually DRC (and also other features) tuning is performed with sounds or music tracks, not single tones.
Have you already gone through section 4.3 of the Smart Amp Tuning Guide?
