Definitive Technology 1x15"Longthrow Woofer and 2-15" Radiators (Black) - Manual (Page 12)

English
The subwoofer has a 3-position power option switch:
• Always on
• Auto on via signal (recommended)
• 12V trigger.
Please note that if you hear a noise from the speaker
when the amp powers up or down, this is normal.
The blue LED on the back panel will light up when
a signal is detected and the amplifier turns on.
The LED is red when in standby and no signal is
detected. Please note that after the cessation of a
signal, it may take up to an hour for the amplifier to
actually turn off. This is nothing to be worried about
as the amp will be in low idle mode which uses very
little power (less than 1/2 Watt).
To prevent accidental damage to your subwoofer
from overdriving the system, the subwoofer features
an internal overload protection circuit, which will
turn the subwoofer off or down when overdriven or
overheated and will then resume normal operation
after a few minutes.
