XPA HC-1
Configuration and Operation
Line Voltage
The XPA HC-1 can operate from any line voltage between 100 VAC and 250 VAC and from any line
frequency between 50 Hz and 60 Hz. The amplifier will automatically detect which line voltage it
is connected to and configure itself accordingly.
AC Power Switch (rear panel)
The rear-panel AC Power switch controls the main AC power for your XPA HC-1. When this switch
is in the Off position, the amplifier will not operate. Turning it On will put the XPA HC-1 into
Standby mode.
AC Circuit Breaker (rear panel)
If an electrical power fault occurs, the button on the rear-panel Circuit Breaker will pop up. When
the Circuit Breaker button is up, the XPA HC-1 will not operate, and neither the Status LED nor the
Standby Button will be lit. The Circuit Breaker is reset by pressing the button firmly in.
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 Switches
This switch selects between the Unbalanced (RCA) and Balanced (XLR) inputs. Only one input
will be active at once. (Both a balanced and an unbalanced source may be connected at the same
time, and the switch used to select between them, but only one will be active at a time.)
Status LED Switch
Disables the front panel Status LED when set to Off.
Trigger Input and Output
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 HC-1 will switch from Standby to On; when the
trigger signal ceases, the XPA HC-1 will return to Off.
The trigger is typically connected to the preamp or pre/pro that provides a signal source for the
XPA HC-1, and set to turn the XPA HC-1 on when the preamp or pre/pro is turned on. For multiple
XPA HC-1 monoblocks, the Trigger Input of each amp may be connected to the Trigger Output of
the previous unit.
Whenever the XPA HC-1 is On, the Trigger Output will assert a 12 VDC signal, which may be used
to turn on other trigger-enabled equipment.
