TRIGGERED POWER CONTROL

Another method for turning the ULTIMA LE-1 on and off is by
means of the POWER TRIGGER IN jack, located on the FM-2
module (see Rear Panel Layout on page 14). When a dc voltage of
between 4 and 15 volts is supplied to this

" mini jack (tip is

positive), the ULTIMA LE-1 will turn on and remain on until the
trigger voltage is removed. 

More reliable than music sensing, trigger control is frequently
available in integrated audio-video systems.  

A NOTE ON POWER MANAGEMENT…..

Power can be controlled by the trigger feature or Automatic Music
Sensor, but not by both simultaneously. If you insert a plug into
the POWER TRIGGER IN jack, be sure to disable the Automatic
Music Sensor. Still, you can always use the front panel POWER
switch to turn the ULTIMA LE-1 on or off, regardless of what
automatic control feature is in use. The POWER switch will
always override the active power control feature in use.  

For example, when Automatic Music Sensor is active, pressing the
POWER switch will turn on the ULTIMA LE-1 even though the
music may be at such a low level that the automatic circuits are not
activated. (For signal levels below threshold, the ULTIMA LE-1 is
kept in the Standby mode, to eliminate its turning on due to tran-
sient signals or stray noise impulses.) If the POWER switch is
pressed off and Automatic Music Sensor is active, the ULTIMA 
LE-1 will enter Standby mode and turn power back on if an audio
signal of sufficient level is present at its inputs.  

If triggered power control is being used, the front panel switch will
turn the ULTIMA LE-1 on or off, regardless of the presence or
absence of a trigger signal. The ULTIMA LE-1 will re-synchronize
with the trigger signal after the trigger signal sequences through
on-off or off-on states, accordingly.
