Setup Choices for Power ON
Caution:
Before making any changes to the AUTO MODE Switch insure that the Master Power
switch on the rear of the amp is OFF. Possible damage to the amp may occur due high transient
current during switching or from wiring misconfiguration.
It has:
1.
Constant ON. It is provided by the Front Panel ON/STANDBY Switch. LED must be Blue.
NOTE:
The rear Master Power Switch must be ON.
2.
DC 12V TRIGGER. The Front Panel ON/STANDBY Switch must be in Standby mode. LED will indicate
red. The tip of the plug is (+).
3.
Auto Mode Music. In this mode the amp will energize automatically by sensing a small current when
an audio signal is applied. The Front Panel ON/STANDBY Switch must be in Standby mode. The
switch LED will indicate red.
Constant ON Mode
In the Constant ON mode the amplifier is energized continually. This is the most inefficient mode of
operation. When in this mode the amp is always running and does not conserve energy. If this
mode is selected, careful attention should be given to the steady heat generated. Make sure there is
ample
ventilation to accommodate the excess heat produced in this mode.
To have power ON constant the ON position of the AUTO MODE Switch on the rear of the panel
must be in the ON location to the left. Turn the MASTER POWER switch on rear of panel to the ON
position. With this switch ON you can now energize the amplifier from the front panel. The switch
toggles from ON to STANDBY. To indicate Constant ON the front LED lights will illuminate Blue.
MUSIC Auto Sense Mode
When the AUTO MODE Switch is in the MUSIC mode the power to the unit is controlled by the input
signal present on either the GLOBAL INPUT or any LINE IN for the separate Channel Zones. When a
low level signal is detected on either of these inputs the amplifier will energize and send speaker
level sound to the selected zones. If after 10 minutes no signal is present the amplifier will
automatically turn off. The delay prevents cycling when there is any pause in the sound/music
source. The Front panel switch must be in STANDBY indicated red on the switch. It should turn Blue
when a signal is detected on the inputs. The amplifier will energize.
DC 12V Trigger Mode
When the AUTO MODE Switch is in DC 12V position the system requires an external trigger to
energize the amplifier. Connect a remote two conductor via a male 3.5mm phone plug to the DC
12V TRIGGER IN jack. The tip is (+) positive and the sleeve is (-) negative. If more than one device
needs to be controlled connect that device to the to the DC 12V TRIGGER Out jack via a male
3.5mm phone plug. The front Power Switch must be in the Standby Mode to operate. The LED on
the Switch will illuminate red when in Standby mode and turn Blue when triggered. This indicates
the amplifier is active.
