XPR-1

Configuration and Operation

Line Voltage
The XPR-1 can operate from line voltages of 115 VAC +/- 10% or 230 VAC +/- 10%,
and will automatically detect and switch between them. The Input Voltage LEDs on the rear
panel indicate which voltage range has been detected.
AC Power Switch (rear panel)
The rear-panel AC Power switch controls the main AC power for your XPR-1. When this
switch is in the Off position, the amplifier will not operate. Turning it On will put the XPR-1
into Standby mode.
Standby Switch (front panel push button)
When the XPR-1 is in Standby mode, the front panel Standby LED (directly above the
switch) will be lit red. Pressing this button once will switch the XPR-1 On (and the LED will
turn blue); pressing it again will return the XPR-1 to Standby mode.
Dim Button (front panel push button)
The Dim button controls the brightness of the blue accent lighting strips (vertical lights near
the sides of the front panel) and the Status LEDs and LED Bargraph Meters. The button
cycles between full brightness and dim in four steps each time it is pressed.
Meter Button (front panel push button)
The Meter button controls whether the LED Bargraph Meters, Status LEDs, and Accent
Lights are lit. The button cycles through "all on", Status LEDs only, "all off", Status LEDs
only, and Status LEDs plus Accent Lighting (but not Meters) each time it is pressed.
Peak Button and Orientation Button (front panel push button)
The Peak button switches the LED Bargraph Meters between Peak and Peak Hold Modes.
The Orientation button switches the LED Bargraphs between vertical, left-to-right, and right-
to-left bars.
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 XPR-1 will switch from Standby to On;
when the trigger signal ceases, the XPR-1 will return to Off.
The trigger is typically connected to the preamp or pre/pro that provides a signal source for
the XPR-1, and set to turn the XPR-1 on when the preamp or pre/pro is turned on.
Whenever the XPR-1 is On, the Trigger Output will assert a 12 VDC signal, which may be
used to turn on other equipment.
