XPA-1L
4., 10. Negative (-) and Positive (+) Speaker Terminals
Audiophile-grade gold plated five-way binding posts accept banana plugs, lugs, or bare
wires.
5. Unbalanced (RCA) Input
Solid machined gold-plated RCA jack accepts a line level unbalanced input.
6. Un-Balanced / Balanced Selector Switch
Switches between the Unbalanced (RCA) and Balanced (XLR) input. Up selects the
Unbalanced input and Down selects the Balanced input. Only one type of input is active at
once. (It is allowed to plug in both balanced and unbalanced sources and use the switch to
select between them, but only one will be active at once.)
7. Balanced (XLR) Input
High quality XLR connector accepts a line level balanced input.
8. Status LED Switch
Disables the front panel status LED when set to Off.
9. Trigger Input and Trigger Output
The XPA-1L is switched On (from Standby) when a trigger signal is presented at the Trigger
Input; the XPA-1L returns to Standby when the trigger signal is removed. When the
XPA-1L is on, a 12 VDC signal is sent from the Trigger Output to control other devices.
11. Input Voltage Indicator
The XPA-1L automatically detects and switches between 115 VAC and 230 VAC. These
indicators tell you which line voltage the XPA-1L has detected.
12. AC Power Switch
Switches the main AC power to the XPA-1L On and Off. When this switch is Off, no controls
operate (the XPA-1L cannot be turned On from the front panel or by a trigger signal).
11. IEC Power Cord Receptacle
Accepts a standard removable IEC AC power cable (a high-quality commercial power cable
is included).
