MICROCONTROLLER UNIT (MCU)
INTELLIGENCE
The built-in MCU controls all of the amplifier's operational
behaviors. It turns the amplifier on and off, monitors various DC
voltages for acceptable values, detects bad ground and output
DC offset conditions, performs various timings, manages input
and DAC selectors, manages EU auto shutdown, and shows
various normal and error/fault conditions. The red/white
STATUS LED on the front panel is used to indicate these
conditions with various colors and blink rates. Refer to the
BLINK CODES section for details. Please review this section
before attempting to operate the Monolith™ Liquid Gold
X
amplifier.
DC Plug-In Delay
The
Monolith™ Liquid Gold
X amplifier has several built-in
delays to ensure that all DC voltages are in their proper ranges
before allowing you to power up and connect headphones.
The first important delay is immediately after plugging in DC
power. The MCU waits 3 seconds before measuring the DC
voltage of the power source. If this source is not within range
the MCU will show a blink code using the STATUS LED on the
front panel. You will not be able to power on the amp until the
