Dynamics 137 ATTACK-This determines how soon the signal is expanded once the Expander has been activated. With a fast attack time, the signal is expanded almost immediately. With a slow attack time, however, the initial transient of a sound passes through unaffected. Attack times from 1 to 5 milliseconds are a good place to start. RELEASE-This determines how soon the Expander returns to its normal gain once the trigger signal level exceeds the threshold. If the release time is too short, the gain will recover too quickly causing level pumping (i.e., noticeable gain fluctuations). If it is set too long, the Expander may not have time to recover before the next low-level signal appears and it will be expanded incorrectly. Release times from 0.1 to 0.5 seconds are a good place to start. GAIN-This sets the Expander's output signal level, and can be used to compensate for the overall level change caused by the expansion process. DME32-Owner's Manual
