Configuration and Operation
Line Voltage
Verify that the Line Voltage switch (protected slide switch on the rear panel) is set for the
proper supply voltage for your area.
Status ring
The ring around the front panel Volume control illuminates to show status.
• OFF indicates that AC Power is switched off (or is missing).
• BLUE indicates that the A-100 is on and operating normally (the blue Position LED on
the knob should also be illuminated).
• AMBER indicates that the A-100 is in Standby mode.
• FLASHING AMBER indicates that the A-100 is in Protect mode.
Power Mode switch
The Power Mode switch controls how the A-100 reacts to audio inputs, trigger control
signals, and the AC Power switch.
The front panel Volume control sets only the level for the Speaker outputs (it does not affect
the loop output).
When the rear panel AC Power switch is set to Off, the A-100 X will not respond to any input
or signal.
WhenthePowerModeswitchissettoOn- the A-100 is controlled only by AC Power
switch. When the AC Power switch is Off, the A-100 will not operate. When the AC Power
switch is On, the A-100 will operate; the Speaker Outputs will be active and audio signal
present at the Input will be buffered and sent to the loop Output.
WhenthePowerModeswitchissettoOff-the A-100 is controlled by the AC Power
switch AND the Trigger Input. When the AC Power switch is Off, the A-100 will not operate.
When the AC Power switch is On, the A-100 will remain in Standby mode until a Trigger
input is received . When the Trigger Input is active, the A-100 will switch On and operate;
the Speaker Outputs will be active, audio signal present at the Input will be buffered and
sent to the loop Output, and the Trigger Output will be active.
WhenthePowerModeswitchissettoAuto-the A-100 is controlled by the AC Power
switch and the audio signal. When the AC Power switch is Off, the A-100 will not operate.
When the AC Power switch is On, the A-100 will remain in Standby mode until audio signal
is detected at the input. When the A-100 is in Standby mode and an audio is sensed at the
input, the A-100 will switch On and operate; the Speaker Outputs will be active, and audio
signal present at the Input will be buffered and sent to the loop Output.
