loudspeakers for all the sources except the Tuners. The range is between 0 and 100.
Sets the prescale values for the Nicam standard sounds for tuner inputs. Changing this value you
can adjust the level of the output sound going to loudspeakers for Nicam sounds entering the analog sound input of MSP. The range is between 0 and 100.
Sets the prescale values for the FM/AM standard sounds for tuner inputs. Changing this value you
can adjust the level of the output sound going to loudspeakers for FM/AM sounds entering the
analog sound input of MSP. The range is between 0 and 100.
Sets the input voltage going to IF decoder AGC pin. Changing this value you can adjust this voltage for optimum Tuner performance. The range is between 0 and 31.
These are used for color bias adjustment. The range is between 0 and 255
