XPA-2
XPA-2 Rear Panel
1. Trigger Input and Trigger Output
The XPA-2 is switched On (from Standby) when a trigger signal is presented at the Trigger Input;
the XPA-2 returns to Standby when the trigger signal is removed. When the XPA-2 is on, a 12 VDC
signal is sent from the Trigger Output to control other devices.
2. Status LED Switch
Disables the front panel status LEDs when set to Off.
3. Meter LED Switch
Disables the multi-segment LED bargraph meters when set to Off.
4., 10. Balanced (XLR) Inputs
Standard XLR connectors (accept line level balanced inputs).
5., 9. Un-Balanced / Balanced Selector Switches
High-quality metal toggle switches independently select 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 for each channel. (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.)
