Automatic Dynamic Loudness Contouring (ADLC) technology ensures a fuller and comfortable listening experience especially at low perceived levels. Based on industry leading technology from TC Electronic, ADLC ensures that amplifiers make the best of what comes into the system regardless of output gain (or volume). At the limits of a loudspeakers SPL capability, the amplifier extends its useable range, keeping distortion at bay.  This dynamic processing automatically eases off at higher SPL so that the system maintains a consistent full-bandwidth sound with full impact at all listening levels.
