What is the advantage of a fast Slew Rate ?
A. In order to maintain audio signal transients, an amplifier must be fast enough to reproduce them without distortion. Transient Intermodulation Distortion (TID) is a specification often overlooked in audio circuit design. With the advent of digital recording devices, the analog input levels required for Full Scale Deflection (0dBFS), can be in the order of +20dBu so it is important that the driving device is capable of reproducing transients at this elevated level. The MA-2.2 design and slew rate of 140V/uS ensures low levels of TID right up to +24dBu.
