Remote Connections
7 12 VDC In/Out (12 V Trigger)
The 12 V trigger allows you to turn the Evolution amplifier on or to stand-by
from other components.
Out. The output sends 12 VDC (12 V trigger) power on/off signals to other Krell
components and other devices that incorporate a 12 V trigger, allowing whole
systems or parts of systems to be easily controlled remotely. Mono 3.5 mm
connectors are used in the following configuration: Tip = +12 V, Sleeve = GND.
Notes
When an Evolution amplifier is in the operational mode, the 12 V trigger provides 12 Volts
of DC output. When the amplifier is in the stand-by mode or off, the DC output is
0 Volts. A maximum of 30 mA is available from the 12 V trigger output.
Consult the owner's reference of the components used in a custom installation to take
full advantage of the remote capabilities of an Evolution amplifier.
