Hi Yosuk

All iLive digital inputs have a Sample Rate Converter (SRC) on each digital input pair.

The SRC will convert incoming AES/SPDIF/optical signals to be in sync with the internal iLive sampling clock (48kHz).

This deals with drift or small external sampling rate differences between external inputs. Or compatibility with other input sampling rates, for example, 44.1kHz or 96kHz.

It also allows the system to run without external wordclock sync between all devices.

For sync’d systems where the external device is in sync with the iLive internal clock, it is possible to disable the SRC, in channel pairs. This can reduce latency through the SRC where latency is absolute critical. SRC latency can accumulate in cascaded digital devices all using SRC. This can be problematic in vocal/percussive musician monitor feeds or broadcast monitoring feeds.

By default the SRC is On, therefore you do not need to worry about any syncing issues.

If you are outputing audio from the iLive digital outputs, you will need to configure the device you are sending audio to so that it can recieve the audio at 48kHz. You may also need to set the device as a slave, check the manual of the AES device you are connecting the iLive to.

Hope this helps
