1. PPP PPP PPP PP PPP PP gt gt gt gt Due to the internal signal phase corrections the synthesizer can re lock temporarily when switching S PDIF clock frequencies This does not affect the output signals or functionality of iCLOCK S PDIF clock rates are set independently of externally applied clocks Thus iCLOCK provides S PDIF clock conversion from all supported input rates to all generatable output rates DIST does not provide redundancy for the S PDIF outputs If the external S PDIF or AES3 11 signal source fails the S PDIF output pair will fail too If the professional format is selected the physical parameters of the output terminals unbalanced operation level and impedance will remain unchanged The functions and settings displayed on the S PDIF menu pages are automatically adapted with regard to the channel status bits of the professional format Example There are S PDIF receiver circuits causing problems when synchronizing to S PDIF blank frame signals This usually results in increased Jitter and signal instabilities Enabling a DC offset level in the S PDIF blank frame signal will allow for synchronizing any S PDIF input stage This level can normally be processed wi thout problems by the concerning S PDIF input stages thus ensuring reliable synchronization IP hor H Pei function FORMAT This function allows for altering the S PDIF format stored in
