(Pair) Differential Reference™ Monoblock Power Amplifiers with Switchable Class A or Class A/B Operation
Features offered by the XPA-1L include:  • Fully balanced, Differential Reference™ design with quad differential input stage and     cross-coupled active current sources.  • Switchable Class A and Class A/B operating modes.  • Massive, high current toroidal power supply.  • Advanced microprocessor operating system which protects the amplifier from all fault     conditions.  • Discrete differential front end, no integrated circuits.  • Balanced and unbalanced inputs.  • Trigger input and output.  • Front panel status LED with switchable stealth mode.  • Fully protected from all fault conditions.  • Machined, gold plated, unbalanced RCA input connector.  • Heavy duty, gold plated, clear jacketed audiophile speaker binding posts.  • Soft-touch power switch.  • Solid milled aluminum faceplate.  • Automatic 120/230 AC voltage detection and switching.  • IEC power inlet.  • Laser etched serial number badge.  • Transferrable warranty.  (These units have warranty until September 24, 2018).

Topology:  Fully balanced, fully discrete, quad differential, high current, short signal path, with user switchable Class A or Class A/B operation. 
Number of Channels:  1 
Power Output (rated power; THD < 0.1%):  250 watts into 8 Ohms; Class A/B operation.  500 watts into 4 Ohms; Class A/B operation.  35 watts Class A, transitioning to 250 watts Class A/B into 8 ohms; Class A operation. (Note: In Class A mode, the XPA-1L operates in pure Class A mode at all power levels up to 35 watts, at which point it automatically transitions into Class A/B mode). 
Rated Power Bandwidth (at rated power; 8 Ohm load):  20 Hz to 20 kHz + / - 0.15 dB. 
Minimum Recommended Load Impedance:  4 Ohms (which equals one 4 Ohm load or two paralleled 8 Ohm loads). 
Frequency Response:  10 Hz to 80 kHz (+ 0 / - 2 dB). 
THD + noise:  < 0.005% 
Signal to Noise Ratio (8 Ohm load):  > 90 dB at 1 watt (A-weighted).  > 116 dB at rated power (A-weighted). 
Damping Factor (8 Ohm load):  > 500 
Speaker Output Connections:  Audiophile grade five-way binding posts, gold plated with clear insulator, 1 pair. 
Power Supply:  90,000 uF of storage capacitance.  450 VA heavy duty toroidal transformer. 
Input Sensitivity (for rated power; 8 Ohm load):  1800 mV. 
Gain:  29 dB. 
Input Connections:  Unbalanced (RCA); balanced (XLR); switchable. 
Input Impedance:  50k ohms. 
Trigger:  Trigger Input: 5 - 20 V (AC or DC); <10 mA input current required.  Trigger Output: 12 VDC; can drive any load up to 100 mA. 
Power Requirements:  115 VAC or 230 VAC +/- 10% @ 50 / 60 Hz (automatically detected and switched). 
Front Panel Controls and Indicators:  Standby; push button (halo ring changes color to indicate Standby or On).  Status LED; illuminates blue for normal operation, flashes red during power-up or when a fault occurs (may be disabled by rear panel Status LED switch). 
Rear Panel Controls:  AC Power switch; rocker switch (switches AC mains power).  Status LED switch; small slide switch (disables front panel Status LED).  Input selector; toggle switch (selects between balanced and unbalanced inputs).
Protection:  The XPA-1L is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions. 
Dimensions:  17” wide x 3.875” high x 19” deep (includes feet and binding posts). 23” x 24.5” x 8.75” (boxed). 
Weight:  35 pounds unboxed (45 pounds boxed).
