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.
