wheveverTV inputisselected thevolumeandbalancecontrolswouldbelockedatunitygain.Ifotherinputswere
subsequentlyselected,volumeandbalancecontrolsreturntonormaloperationforthoseotherinputsources.Only
theTVinputswouldbelockedatunitygain.PASSTHROUGHmode,therefore,canonlybeassignedtooneinput
atatime,butthatinputcanbeanyoneoftheanalogaudioinputs.Thepoweramplifierstageisnotaffectedby
