4.2 Operating modes
The C1.2 DAC/Controller has two main operating modes: Normal mode and Menu mode. Normal mode is used
to access standard preamplifier controls (selection, switching and setting level) whereas Menu mode is used to
configure the unit. The C1.2 also includes Shortcuts for quick access to selected Menu mode items. Shortcuts are
user programmable and most Menu mode items can be selected as Shortcuts.
4.2.1 Normal mode
Normal mode is used for standard preamplifier functions. When powered-on, the C1.2 starts in Normal mode.
The display looks as follows:
Normal mode display elements
1. Data type (PCM, DSD, MQA or MQA Studio) and the
incoming audio stream’s original sample rate.
2. Mute indication. If the
7
symbol is present, the
output is muted
3. Analog output level. Only displayed when the C1.2
is used as a preamplifier. When C1.2 is used as a pure
DAC (selectable through the Factory Settings menu),
output level is set to 0 dB and “DAC” is displayed.
4. Analog audio output signal polarity (phase)
indication. If the
H
symbol is present, polarity is
reversed
5. External power supply indication. When an
external power supply is connected and engaged,
<
symbol is displayed and internal power supply is
turned off
6. Clock source indication (internal, audio in, or clock
frequency when an external clock is selected as the
clock source)
7. Lock indication (

or

). Tells if the unit is locked to
a clock source or not
8. Input source name. Each input source can be
