6.5. Ecomode (power saving mode)
The
Ecomode
serves to reduce heat and unnecessary power consumption when the unit is switched
on but not in use. After approximately 8-12 minutes without receiving signal, the MRE 220 SE
Ecomode is activated, turning down the power. In this “sleep” mode, the MRE 220 SE draws less
than 20 W Idle current. Therefore the running unit produces no heat, because the heater voltage and
the high voltage for the power amplifier section are switched off. When the music signal is once again
sensed by the MRE 220 SE, the Ecomode circuit will turn the unit back on, with a warm-up/start-up
delay of approximately 60 seconds before the unit will operate.
The Ecomode also serves to increase the lifetime of the tubes, while having an added benefit of
improved safety
allowing the MRE 220 SE owner a level of security against any problems when
leaving the unit powered on. The Ecomode is a safety and energy-saving feature that automatically
switches off the amplifier's tube circuitry during breaks of approximately 8-12 minutes.
Ecomode reduces the overall power consumption of the amplifier to under 20W, compared with
180W in normal operation. When detecting a signal, the MRE 220 SE reactivates automatically and
is ready for use again within approximately 60 seconds.
Eco off:
The Ecomode function is off, the Ecomode
LED on the top doesn’t burn.
Eco on:
LED display on the top side:
The Ecomode function is activated. The
Ecomode LED lights up in GREEN.
After an approximately 10-minute silence,
Ecomode turn the Unit down. The Ecomode
LED changes to RED/Orange indicating
that the Ecomode circuit is powering down
the unit.
Note:
If you switch the MRE 220 SE on with Ecomode active, it will go through the start procedure. If it
fails to detect a music signal, it will shut down after approximately 10 minutes. Ecomode is not the
same as standby, however, because certain sections of the amplifier remain on.
Important!
You cannot adjust the BIAS in Ecomode once the amplifier has powered
down!
The signal switching level of 0.6 mV results in approx. 40 µW output power
of the MRE 220 SE. In case of a speaker with a high efficiency an adjusted
listening level can be lower than this value. The Ecomode would drive the
unit down. In such cases the Ecomode should be switched off
