XPA-1L
XPA-1L Front and Rear Panels
1. Class A - Class A/B Mode Switch
When this switch is in the Class A/B position, the XPA-1L functions as a very high quality,
low distortion Class A/B amplifier (250 watts @ 8 ohms / 500 watts @ 4 ohms).
When this switch is in the Class A position, the XPA-1L functions as a pure Class A amplifier
for all signals up to 35 watts. If the signal level exceeds 35 watts, the XPA-1L automatically
transitions seamlessly into Class A/B mode and delivers its full rated power.
2. Status Display Window
This window houses the status LED. When the XPA-1L is Off or in Standby mode, the
Status LED will be unlit. When the XPA-1L is powered On, the Status LED will illuminate red
for a few seconds and then turn blue. If a fault occurs, the LED will flash red.
Note: The status lED switch on the rear panel disables the lED when set to off.
3. Standby 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.
