Front Panel Layout
Front Panel LED Display
The front panel display contains Status LED lighting to indicate the condition of the XPA-1.
NO LED = Amplifier is OFF
BLUE LED = Normal Operation
FLASHING RED LED = Fault Condition
See “Troubleshooting” section for details.
Front Panel Power Switch
This switch provides the ON/OFF control of the
XPA-1 from the front panel. When the unit is
off and in standby mode, the switch illuminates
amber. Automatic switching is accomplished
with the 3.5mm trigger input on the back panel
using a 5-12VDC control signal.
Rubber Feet
These rubber feet keep the XPA-1 elevated for bottom ventilation as well as for vibration isolation.
