Addition in V1.20 (May 26, 2023)

[NT-505-X]/[UD-505-X]
 The clock synchronization function can now also be used when the input source is COAXIAL1/2 or OPTICAL1/2.
 Clock synchronization can be turned on or off separately for each input source.

 ATTENTION
 To use clock synchronization with COAXIAL1/2 or OPTICAL1/2, the connected digital audio output device must support
 clock synchronization and be synchronized to the same clock output device as this unit.
 If only this unit is synchronized to the clock output device, noise might occur in the playback sound.
