Confi gure Trigger
Overview
A trigger is an industry standard interface where a wire is connected between components
enabling control the power on or off sequence simultaneously or with a delay. The Evolution
707 uses standard 12v DC Triggers. KRELL components use a constant 12v for a power
ON state and 0 volts for the power OFF state. Connect a 12v trigger cable to one of the 4
trigger outputs on the Evolution 707. Connect the other end of the trigger cable to the
Trigger input of a multi-channel amplifi er for example. Triggers can also be utilized to turn
on certain components associated with specifi c inputs while turning off others. 12v trigger
cables are terminated with 1/8” phone jacks.
Confi gure Trigger
Select a button preset device to confi gure.
Choose whether one or all the triggers will be confi gured at once. The options are:
Selective or All triggers. If the all triggers option is selected then the Mode and
delay will be confi gured for all (4) trigger outputs for that selected button preset.
If Selective is used then each trigger can be confi gured individually for that button
preset. The selective options are Trigger 1, Trigger 2, Trigger 3 and Trigger 4.
NOTE:
Trigger 1 is enabled for all button presets by default.
Mode sets the behavior of each specifi ed trigger the options are:
Main Only – Trigger output is active for the Main zone only for the selected device.
Main and Zone 2 – Trigger output is active for both the Main zone and Zone 2 for the
selected device.
Always Off –Trigger output is OFF for Main and Zone 2 for the selected device.
Zone 2 Only - Trigger output is active for the Zone 2 only for the selected device.
Delay - sets the time delay between when the device button is selected and the 12v signal is
sent. This is an added feature to allow the staggering of when components turn on, this can
be critical when big power amplifi ers are in use. The delay setting is between 1 Second and
30 Seconds.
