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.
Only replace the fuse(s) in the XPA-1 with fuse(s) of proper value and voltage rating. The XPA-1 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. ! You should seek service for your XPA-1 by qualified service personnel if any of the following occur: 1. The power-supply cord or the plug has been damaged. 2.

XPA-1 Introduction Thank you for purchasing the new and improved second generation Emotiva XPA-1 Differential Reference™ Monoblock power amplifier. Monoblocks deliver the absolute best in audiophile quality sound; totally separate amplifiers, each with its own independent power supply, provide the ultimate in channel separation and pristine sound quality.
XPA-1 About This Manual This manual will provide you with the information you need to get started enjoying your XPA-1 stereo 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. If you’re really in a hurry to get started, please read the Quick Start section (on page 10); you may then read the remainder of the manual at your leisure.
XPA-1 Features The XPA-1 Differential Reference™ Monoblock Power Amplifier features our fully discrete, highcurrent, 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-1 also has an exciting new feature.
XPA-1 Unpacking Your XPA-1 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-1 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.
XPA-1 XPA-1 Front Panel 1 2 3 4 ® CLASS A A/B ® STANDBY 1. Class A - Class A/B Mode Switch When this switch is in the Class A/B position, the XPA-1 functions as a very high quality, low distortion Class A/B amplifier (600 watts @ 8 ohms / 1000 watts @ 4 ohms). When this switch is in the Class A position, the XPA-1 functions as a pure Class A amplifier for all signals up to 60 watts.

Two positive and two negative binding posts are provided to facilitate bi-wiring (both negative terminals are electrically the same, as are both positive terminals). DO NOT connect the negative (-) speaker terminal of the XPA-1 to ground, or to the negative speaker terminal of another amplifier.
XPA-1 4. Trigger Input and Trigger Output The XPA-1 is switched On (from Standby) when a trigger signal is presented at the Trigger Input; the XPA-1 returns to Standby when the trigger signal is removed. When the XPA-1 is on, a 12 VDC signal is sent from the Trigger Output to control other devices. 5. Unbalanced (RCA) Input Audiophile quality gold plated machined RCA input connector (accepts a line level unbalanced input). 6.
XPA-1 Quick Start To get the most from your XPA-1, 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-1’s. Connect your XPA-1’s to a signal source. Connect each of your XPA-1’s 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-1 Connections Connecting speakers to your XPA-1 Your XPA-1 has no special connection requirements; audiophile grade five-way binding posts are provided for speaker connections. • 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-1. • Always use high-quality speaker wire; 18-gauge or heavier.
XPA-1 Connecting the Trigger Input and Trigger Output The Trigger Input accepts a 12 VDC (nominal) trigger signal from another device via a standard 1/8” mono plug. When the trigger is asserted, the XPA-1 will switch On; when the trigger is removed, the XPA-1 will return to Standby mode. The Trigger Output sends out 12 VDC whenever the main power to the XPA-1 is On (and NOT when it is in Standby mode) which can be used to switch on other units with trigger capabilities.
XPA-1 Configuration and Operation Line Voltage The XPA-1 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-1 has detected. AC Power Switch (rear panel) The rear-panel AC Power switch controls the main AC power for your XPA-1. When this switch is in the Off position, the amplifier will not operate.
XPA-1 Care and Maintenance Periodic Maintenance Your XPA-1 requires no periodic maintenance or calibration. Cleaning your XPA-1 • • If necessary, the XPA-1 should be cleaned gently with a soft rag. If something sticky gets on the front panel or case of the XPA-1, 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.

XPA-1 Troubleshooting The XPA-1 is carefully designed and manufactured from high-quality precision components to ensure years of trouble free operation. We really doubt you’ll ever have any problems with your XPA-1, but if you do, here are a few things you could try: Problem: No output (nothing is lit). Reason: You have no AC power. • • • Verify that the rear panel AC Power switch is On. Verify that your circuit is live. Verify that the line cord on the XPA-1 is fully inserted and is tight.
XPA-1 Problem: The halo around the Standby button is lit amber and the XPA-1 fails to come on when triggered. Reason: The XPA-1 is in Standby mode and should respond to a valid trigger signal. • • Check your trigger cable. Check the trigger settings on your source equipment. Problem: No sound is heard; the LEDs are flashing red. Reason: The XPA-1 is in Protect mode, which indicates a fault condition. • • • • Switch the rear panel AC Power switch Off and On to clear the Fault condition.
