Fixed means there’s a constant full scale output – most often used as ‘tape out’ or when using a Lyngdorf Audio TDAI or SDAI as a second ‘slave’ amplifier in a bi-amping set-up. Regulated (variable) means that the output level will follow the level of the volume control. This setting is chosen if you have, for instance, a power amplifier or an active subwoofer connected. -
