Soft Limit™ is a superior analog design preventing the digital clipping that causes distortion by instantaneously rounding off transient peaks before they hit the analog-to-digital converter. This technology allows several more decibels of apparent level to be recorded while subtly providing an analog-like warmth to the sound.
An Apogee technology first introduced in 1992 on Apogee’s AD-500 converter, Soft Limit can be heard on countless platinum selling records around the world. Once a technology exclusively reserved for Apogee’s most advanced audio converters, Soft Limit is now available in most current Apogee products such as Duet, Quartet, Element & Ensemble, as well as Symphony I/O
With Duet 2 and Quartet, Soft Limit has a single setting utilizing the default -2dB threshold:
With Symphony I/O and Maestro 2, there are 4 available settings: -2 dB. -4 dBfs, Soft Saturate and Soft Crush. Each setting possesses its own characteristics for a wide range of versatility in the analog-to-digital conversion process. You can read more about Soft Limit on Symphony I/O here:
