April Music Stello DA100 - Manual (Page 5)

2. Front Panel
POWER :
Turn the switch lever up to turn on the unit. Red LED will be on to
indicate the DA100 is operating.
UPSAMPLE : Y ou can select either 192kHz/24 Bit upsampling or Bypass.
‘BYPASS’ means the digital output is exactly same as the digital input (up to
96kHz/24 Bit).
You should be the judge to decide which mode is better because the musicality
and nuance vary depending on the recording status of the sources.
Generally, we recommend 192 upsampling for most of the playback.
LOCK : Indicate that the input digital signal has been detected by DA100.
INPUT : Select one input you want to listen out of 4 digital inputs.
1 Coaxial, 2 Optical and 1 USB (Universal Serial Bus) inputs are supplied.
