Important Safety Precautions and Explanation of Symbols ! The exclamation point within an equilateral triangle is intended to alert the user to the presence of important installation, operation, and service instructions in this manual. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltages within the enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to the user.
The power cable for the XPA-1L should be unplugged from the outlet during severe electrical storms, or when unused for a long period of time. Only replace the fuse(s) in the XPA-1L with fuse(s) of proper value and voltage rating. The XPA-1L should only be cleaned as directed in the Manual. Avoid spraying liquids directly onto the unit and NEVER spray liquids into the vents. Care should be taken so that small objects do not fall into the inside of the unit.

XPA-1L Introduction Ask any audiophile what kind of amplifier they dream about owning, and they’ll tell you: “A set of Class A mono-blocks!” Audiophiles know that Class A amps sound the best. There is zero crossover distortion, and the output devices are biased up to their most linear operating range.
XPA-1L About This Manual This User Manual will provide you with the information you need to get started enjoying your XPA-1L Differential Reference™ Monoblock Power Amplifier. We suggest that you read through the entire manual; we kept things as short and direct as possible. Even if you’re an expert user, you will probably find some interesting information and useful suggestions.
XPA-1L Features The XPA-1L Differential Reference™ Monoblock Power Amplifier features our fully discrete, high-current, short signal path, class A/B output section, and all the advanced engineering and high quality construction you’ve come to expect from Emotiva. The XPA-1L also has an exciting new feature.
XPA-1L Unpacking Your XPA-1L was carefully packed and should reach you in perfect condition. If you notice any shipping damage or other issues when you unpack it, please contact Emotiva immediately. Gently remove your XPA-1L from the packing carton and remove all wrappings and shipping material. It is important to save the box and all packing materials in case your power amp ever needs to be moved or shipped back to the factory for service. We truly value customer feedback and would like to hear from you.

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).
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.
XPA-1L Quick Start To get the most from your XPA-1L, we urge you to read the entire manual. If you just can’t wait to listen to it, this section will cover the basics you need to get started. • • • Find a secure location for your XPA-1L (you probably have a pair of them). Connect your XPA-1L to a signal source. Connect your XPA-1L to a speaker (4 ohm or 8 ohm) using reasonably heavy gauge speaker wires (at least 18 gauge). • Find some music you really like to listen to.
XPA-1L Connections Connecting speakers to your XPA-1L Your XPA-1L has no special connection requirements; audiophile grade, gold plated, fiveway binding posts are provided for connecting one speaker. • • • • • • • • ALWAYS turn off the amplifier before connecting or disconnecting speaker cables or signal source interconnects. ALWAYS verify that your speaker cables are firmly attached, and not shorted to each other or to any other cables, before powering up your XPA-1L.
XPA-1L Configuration and Operation Line Voltage The XPA-1L can operate from line voltages of 115 VAC +/- 10% or 230 VAC +/- 10%. The amplifier will automatically detect which line voltage it is connected to and configure itself accordingly. The Line Voltage indicators will tell you which line voltage the XPA-1L has detected. AC Power Switch (rear panel) The rear-panel AC Power switch controls the main AC power for your XPA-1L. When this switch is in the Off position, the amplifier will not operate.
XPA-1L Care and Maintenance Periodic Maintenance Your XPA-1L requires no periodic maintenance or calibration. Cleaning your XPA-1L • • If necessary, the XPA-1L should be cleaned gently with a soft rag. If something sticky gets on the front panel or case of the XPA-1L, it should be cleaned with a mild cleaning solution applied to a soft rag, followed by wiping with a clean rag dampened with plain water and drying with a soft dry rag or cloth.
