Remote Connections

712 VDC In/Out (12 V Trigger)

The 12 V trigger allows you to turn the Evolution amplifier on or off, or to and from 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.

8Backlight Control

Ext In. Connect a 12 V trigger to the Ext In input connector to turn off the power status indicator (2) using a remote control. The switch must be set to On/Ext, in order for this to function (see below).

On/Ext. This activates the power status indicator. (This is the factory default position.)

Off. This turns off the power status indicator, during normal operation. The power status indicator remains illuminated for ten seconds after the power but- ton is pressed.
