Incremental volume control only – no continuous amplification/volume control allowed?
The size of the increment may be infinitesimally small, so a ‘continuous’ amplification/volume control is allowed. Rather than continuous, a suggested term is ‘variable’ volume control. The term ‘incremental’ is to distinguish from controls that only go directly to the maximum level. Thus, while the increment may be infinitesimally small, it should not be a single increment the size of the entire range of volume.
