Control elements on the front panel
The front panel has six keys to control the STERN (refer to section 'Overview
front panel' on page 7). You can control all functions with these keys as well as
all setup options to adjust the unit to your preferences (see section 'Setup Menu'
on page 23).
Use the key to switch the STERN on or off. There is a circular operating
indicator around the key, which lights up when the STERN is up and running,
ready to play back music.
The five keys directly underneath the display are dynamically assigned with
functions by the current operating mode of the STERN. The given function of a
key is shown as text in the display right above each key. If no text is displayed,
the key has no function in the present operating mode.
The rotary encoder is used to control the volume setting of the STERN (see
the following section 'Volume control') but as well for navigating through the
menus and user options.

Volume control
The rotary encoder on the front panel of the STERN is used to set the desired
volume level. Turn the rotary encoder clockwise to increase and counter clock-
wise to decrease the volume.
The volume control of the STERN has a range from –80 dB to +10 dB in real
1 dB steps relatively to the level of the input signal. Differences in input levels can
be adjusted for each input channel of the STERN separately (see section 'Offset'
on page 45).
The rotary encoder is a magnetically buffered incremental impulse encoder with-
out an end stop.
The display shows the current volume level in dB during the change of the volume
level as well as a bar graph of the volume in an enlarged manner for a better
readability:
