Input Indicators
In normal use, one of these indicators (J) illuminates to indicate the selected input. For Dual AES, both
AES 1 and AES 2 indicators illuminate. If the DAC is not receiving data through the selected input, the
indicator will flash.
Sample Rate Indicators
The column of sample rate indicators (K) remain off when the unit is not locked. When the unit locks to
incoming digital data, the indicator for the detected sample rate will illuminate. When receiving DSD
data, the 176.4 and
192 indicators illuminate.
When the volume is adjusted, the function of these indicators changes to show the volume setting in
10dB steps, see the table below. 5 seconds after the last volume adjustment, they display the sample
rate once more.
