6. User changes trigger output turn-on time (During power-up only) (Front panel or
RS-232 port) (Unlocked mode only)
Triggers are used to remotely power on other components in the system, such as
power amplifiers, which are turned on after the preamplifier is warmed up. Trigger
outputs are typically 12 Volt systems, connected via hardwired connection between
components. Triggers typically perform a hold function: when power is released the
remotely powered component automatically powers down.
User input:
User holds down either of Input 1 or 2 buttons (for trigger 1 or 2).
To set trigger timer, user rotates control knob clockwise to 99
maximum (to increase trigger time) or counter-clockwise to 01
minimum (to decrease trigger time). Rotating volume control
counter-clockwise until numerical display shows OF turns off
selected trigger. Addressable through RS-232 port also – see specific
section for command structure.
No two triggers can be set for the same turn on time - numerical
display skips already selected trigger times.
