Production Data
The output mixers LOPMIX and LONMIX and their outputs LOP and LON are controlled as described
in Table 39. Care should be taken to avoid clipping when enabling more than one path to LOP or
LON. The LOATTN attenuation control can be used to prevent clipping when more than one full scale
signal is input to the LOP mixer.
