Automatic Mode Control
MERAK will run at
WARM-UP
mode as soon as the mains power is connected and mains
switch set to 'I' position. If automatic mode control is enabled, MERAK will monitor the
input, waking up by any valid music signal above about 5mV and after going back to
warm-up mode if music signal disappeared for a continuous 5 minutes long.
WARM-UP MODE
: MERAK shut down its output stage to save energy while leave the
Class-A signal amplify circuit and Purer-Power supply unit in working status. At a little
expense of less than 5 watt energy consumption, the signal amplify circuit which usually
requires warm-up to achieve the best performance is always in best order.
Any manual operation of the control switch will temporarily disable the automatic mode:
If you wake up MERAK by manual, it will never back to warm-up mode automatically.
If you shut MERAK down to warm-up mode by manual, the mode control is tempo-
rarily disabled and will not enable again unless the music signal on the input disap-
pear for a continuous 5 minutes.
The automatic mode control function is enabled by default to maximum the energy saving
but can be set by user:
DISABLE
: when unit is wake up, press the control switch on the front panel and hold
for 3 seconds, as long as you see the LED start to flash, release the button, the au-
tomatic mode control is disabled.
ENABLE
: when unit is in warm-up mode, press the control switch on the front panel
and hold for 3 seconds, as long as you see the LED start to flash, release the button,
the automatic mode control is enabled.
Burn-in period and Warm-up
As the same with the other audio components, MERAK requests at least 100 hours music
signal burn-in to achieve its designed performance; the sonic will be in best after 500
hours music signal burn-in.
MERAK will not request any warm-up if power switch is keep at on position during daily
use. However, the warm-up time from power off to best operation status will be about 60
minutes in long.
