1. DESCRIPTION OF THE V 40 SE
Power Management and the Ecomode:
The V 40 SE input and output tube heaters as well as its high-voltage rails are logic controlled to
ensure that the conduction of the output tubes as well as input stage voltages are constantly
monitored and controlled by the
Power Management System
to protect the vital internal parts
(tubes, rectifier, electrolytic caps, switches, etc.) against excessive turn-on current. This increases
the lifetime not only of the tubes, but also the caps, while all power related components derive benefit
through this system.
The
Ecomode
serves to reduce heat and unnecessary power consumption when the unit is switched
on but not in use. After approx. 7 minutes without receiving signal, the V 40 SE Ecomode is activated,
turning down the power. In this “sleep” mode, the V 40 SE draws only 10 W Idle current. Therefore,
nearly no heat is produced by the running unit, and 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 V 40
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 V 40 SE owner a level of security against any problems when leaving
the unit powered on.
