Nuvo NV-D2120 Installation Manual page 12

Setting the power mode switch to the left in the Audio mode (Fig. 5) sets the amplifier to respond to the presence of an audio signal. If you are
triggering the amplifier in this way, you should expect a slight delay before it turns on.
When the audio signal is removed the amplifier will remain on for approximately three minutes after the incoming audio signal has ended before
the unit turns off. This will prevent the unit from inadvertently turning off when the audio signal is very low or stops temporarily.

When setting the power mode switch to the center (Fig. 6) the amplifier will turn on or off only when the Power button on the front of the amplifier
is pressed.

Setting the power mode switch to the right (Fig. 7) sets the amplifier to respond to an incoming voltage. This voltage can be AC or DC and anything
from 3-30 volts. This is very useful in conjunction with a multiroom audio system or preamp that has a voltage trigger output. In this mode the
D2120 will turn on or off with the source equipment.
