XPA-100

Configuration and Operation

Line Voltage
The XPA-100 can operate from line voltages of 115 VAC +/- 10% or 230 VAC +/- 10%. The
amplifier will automatically detect which line voltage it is connected to and configure itself
accordingly. The Line Voltage indicators will tell you which line voltage the XPA-100 has
detected.
AC Power Switch (rear panel)
The rear-panel AC Power switch controls the main AC power for your XPA-100. When this
switch is in the Off position, the amplifier will not operate. Turning it On will put the XPA-100
into Standby mode.
Standby Switch (front panel push button)
Press to switch the amplifier On; press again to return to Standby; the halo ring around the
button illuminates amber for Standby and blue for On.
Un-Balanced / Balanced Selector Switch
Switches between the Unbalanced (RCA) and Balanced (XLR) inputs. Up selects the
Unbalanced input and Down selects the Balanced input. Only one input can be used at
once. (It is allowed to plug in both a balanced and an unbalanced source and use the switch
to select between them, but only one will be active at once.)
Status LED Switch
Disables the front panel status LEDs when set to Off.
Trigger
When a trigger cable is connected to the Trigger Input (on the rear panel), and a trigger
signal is received (between 5-20 V - AC or DC), the XPA-100 will switch from Standby to
On; when the trigger signal ceases, the XPA-100 will return to Off.
The trigger is typically connected to the preamp or pre/pro that provides a signal source for
the XPA-100, and set to turn the XPA-100 on when the preamp or pre/pro is turned on.
Whenever the XPA-100 is On, the Trigger Output will assert a 12 VDC signal, which may be
used to turn on other equipment.
