In the Music Player section are various settings required by some DACs to operate smoothly with the Aurender Music Server.
Time delay setting – This setting is for DACs that need time to adjust to sample rate changes. If the beginnings of songs are cut off or there is a slight distortion at the beginning of songs when the sample rate changes, please set the delay time to 3 or 4 seconds and the problems should be solved.
SPDIF setting – There are two formats for SPDIF data structure. Most DACs support both, but some legacy DACs only support one. These legacy DACs will work with the Aurender, if the user selects the Consumer format or Professional format. Most DACs accept both formats and this setting has absolutely no effect on the sound quality.
Use Fade-In/Out – Depending on the DAC or amplifier setup, pops or clicks may be heard when pausing and restarting songs. Turning on the Fade In/Out option can eliminate these popping sounds.
Dual-Wire Mode – To toggle Dual-Wire mode on and off, go to Settings of the iPad App. Turning on Dual-Wire mode will send signals through both AES/EBU outputs. If the Aurender is mistakenly set for Dual-Wire mode and used with a single AES/EBU output, the Aurender will display a sampling rate one-half that of the original rate.
Word Clock Mode – Word Clock is automatically turned on when a word clock signal is detected on the BNC input. When Word Clock mode is on, the SPDIF output will synchronize with the word clock signal.
For 44.1, 88.2 and 176.4 kHz sampling rate music, 44.1, 88.2 and 176.4 kHz word clock or a 22.5792 MHz master clock signal are valid.
For 48, 96 and 192 kHz sampling rate music. 48, 96 and 192 kHz word clock or a 24.576 MHz master clock signal are valid.
An optional USB dongle for dCS Master Clocks is available for automatic word clock frequency selection.
