Specifications

12. Channel Two RCA Audio Input – Connects to the RCA output of a preamplifier or processor. This is the Channel Two
unbalanced connection.
13. Channel Two XLR/Balanced Input – Connects an XLR/Balanced cable to a preamplifier or processor. This is the Channel
Two balanced connection.
14. Channel One Balanced/Unbalanced Input Selector – When the switch is turned towards ‘Un‐Bal’, the RCA (unbalanced)
input is chosen and active. When the switch is turned towards ‘Bal’, the XLR/Balanced input is chosen and active.
15. Channel One RCA Audio Input – Connects to the RCA output of a preamplifier or processor. This is the Channel One
unbalanced connection.
16. Channel One XLR/Balanced Input – Connects an XLR/Balanced cable to a preamplifier or processor. This is the Channel
One balanced connection.
17. Master Power Switch ‐ This rocker switch provides the master power for the amplifier. After it is in the ON position, the
amplifier can be turned on manually from the front panel switch or automatically with the trigger input via 3.5mm input jack.
Under normal use, this switch should remain on, leaving the amplifier in standby position, and coming to full power with
either the front panel ‘STANDBY’ button, or activation through the remote trigger.
In ‘STANDBY’ mode the front panel button will emit an amber glow, but the unit is not fully powered. A small amount of
amps are used in this mode, less than an average night light would use.
If you are away for an extended period of time (more than a few days), shut off all power to the amplifier with the main
power switch on the back of the amplifier.
18. Remote Trigger Input ‐ The XPA‐3 can be remotely triggered by another device. When a remote trigger output from a
preamplifier, processor or other audio device is connected to the trigger input here, the amplifier will power up and shut
down along with the first device.
19. Channel Five Speaker Terminals ‐ Connects to the channel 5 speaker inputs. These 5 way binding posts
accept stripped speaker wire, banana plugs (single or dual), or spade connectors. Be sure to observe correct polarity when connecting
speakers and be sure that the wires do not touch between positive and negative terminals.
20. Channel Four Speaker Terminals ‐ Connects to the channel 4 speaker inputs. These 5 way binding posts accept stripped
speaker wire, banana plugs (single or dual), or spade connectors. Be sure to observe correct polarity when connecting
speakers and be sure that the wires do not touch between positive and negative terminals.
21. Channel Three Speaker Terminals ‐ Connects to the channel 3 speaker inputs. These 5 way binding posts accept
stripped speaker wire, banana plugs (single or dual), or spade connectors. Be sure to observe correct polarity when connecting
speakers and be sure that the wires do not touch between positive and negative terminals.
22. Channel Two Speaker Terminals ‐ Connects to the channel 2 speaker inputs. These 5 way binding posts accept
stripped speaker wire, banana plugs (single or dual), or spade connectors. Be sure to observe correct polarity when connecting
speakers and be sure that the wires do not touch between positive and negative terminals.
23. Channel One Speaker Terminals ‐ Connects to the channel 1 speaker inputs. These 5 way binding posts accept
stripped speaker wire, banana plugs (single or dual), or spade connectors. Be sure to observe correct polarity when connecting
speakers and be sure that the wires do not touch between positive and negative terminals.
Note: Potentially lethal voltages present! Never connect, disconnect or modify speaker wiring with the amplifier turned
on.
24. IEC Power Cable Connection
