2Basic operation
2.1 First operation / self test
In case your Streaming DAC was not connected to mains a self test will be performed when it is
switched on by the mains switch (31) for the first time. The unit will check its configuration and that all
the installed components work properly. The procedure is shown in the display. Afterwards the unit will
switch to stand-by.
2.2 Switching on / stand-by
Using the button power (1) You can switch between on (operate) and stand-by. In the on state the
display (4) lights up and the LED (3) is off. In stand-by mode the display is off and the LED is on to
indicate that the unit is still connected to mains.
CAUTION:When switched to stand-by the unit is still connected to the mains. In case of a
thunderstorm or if you leave the house for a longer time we recommend that you switch the amplifier
off by using the mains switch (31) or pull the mains plug.
2.3 Selecting the signal source
The signal source can be selected by turning the source selector (2) until the desired source appears
on the display. You can choose from a total of 6 (SD 3.2) or 7 (SD 5.2) signal sources. The selected
sound source is labelled with SOURCE and is being shown in large capitals on the left hand side of the
display.
CAUTION:If you choose a digital input that has no valid signal, NO DIG SIGNAL or NO USB
PLUGGED is indicated on the display (4).
3.4 Volume setting
Use the rotary encoder (2) to set the desired volume. Depending on rotating speed the volume
increases / decreases in 0.5 dB steps (slow) or 2 dB steps (fast). The actual setting is shown in the
display (4). The current volume level is labelled with VOLUME and is being shown in large capitals on
the right hand side of the display.
Please notethat if the volume is changed using the RC 9 remote control, the level always increases /
decreases in 2 dB steps.
2.4 Sample rate and filter settings
If a digital input is selected, you can choose from a variety of different sample rate settings by using
the multifunctional buttons (5, 6) entitled CONV. The currently selected sample rate is always shown at
the upper right hand side of the display (44.1, 48, 88.2, 96, 176.4, 192 kHz). The acronym NAT,
standing for "native", entails a direct processing of the signal without changing the original sample
rate. The acronym CNV, standing for "Conversion", indicates an applied upsampling process to the
incoming signal.
Please note that a digital signal can not be downsampled to a lower sample rate (e.g. from 96kHz to
88.2kHz). In case you should listen to music compilations with a variety of different sample rates, we
recommended to primarily make use of the settings NAT SMOOTH or NAT SHARP. The digital filter
settings SMOOTH or SHARP can be set according to your personal preference. Please note that a
chosen filter setting is only true for a selected input and is being recalled every time you select the
respective input again, even when the device has completey been switched off before.
