XPR-1 XPR-1 Mono-block Reference Power Amplifier User Manual
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 electric shock to the user.
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful where the power cable enters the power outlet and the unit. Only connect the XPR-1 an electrical outlet or extension cord of appropriate type and rating. MOST power strips and extension cords are NOT sufficient to safely supply the power required by the XPR-1. Using a power source of insufficient capacity will constitute a safety risk and also seriously compromise the performance of the XPR-1.

When this switch is off, no controls operate (the XPR-1 cannot be turned On from the front panel). 7. IEC Power Cord Receptacle Accepts a standard IEC C19/C20 AC power cable and requires a dedicated 20 Amp high-current AC outlet. If you do not have an appropriate outlet, please contact your electrician to install one.
XPR-1 Quick Start To get the most from your XPR-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 XPR-1s. Make sure you choose a stand or shelf that can support the full weight of the XPR-1s safely. Connect each XPR-1 to your signal source. Connect each XPR-1 to an 8 ohm or 4 ohm speaker using heavy gauge speaker wires (at least 12 gauge).
XPR-1 Connections ! A word about safety The XPR-1 is capable of delivering large voltages and currents at its speaker terminals. If, while music is playing, the speaker terminals or speaker cables are inadvertently shorted to each other, to interconnect cables, or to ground, the XPR-1 can cause damage to associated equipment, and may even pose a risk of electric shock. • • • • Ensure that the XPR-1 is powered Off before changing any connections.
XPR-1 Connecting an input source to your XPR-1 Your XPR-1 amplifier has separate balanced (XLR) and unbalanced (RCA) inputs; a switch selects which input is active. Be sure to set this switch correctly. We suggest using reasonably high quality cables, keeping cables no longer than necessary, and avoiding running signal cables near power cables and speaker cables whenever possible. DO NOT connect a digital signal to the input of your XPR-1 (or you may damage it or your speakers).
XPR-1 Configuration and Operation Line Voltage The XPR-1 can operate from line voltages of 115 VAC +/- 10% or 230 VAC +/- 10%, and will automatically detect and switch between them. The Input Voltage LEDs on the rear panel indicate which voltage range has been detected. AC Power Switch (rear panel) The rear-panel AC Power switch controls the main AC power for your XPR-1. When this switch is in the Off position, the amplifier will not operate. Turning it On will put the XPR-1 into Standby mode.
XPR-1 Care and Maintenance Periodic Maintenance The XPR-1 power amplifier requires no periodic maintenance or calibration. Cleaning the XPR-1 • • • If necessary, the XPR-1 should be cleaned gently with a soft rag. If something sticky gets on the front panel or case of the XPR-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.

XPR-1 Troubleshooting The XPR-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 XPR-1 but, if you do, here are a few things you could try: Problem: No sound is heard (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 XPR-1 is fully inserted and is tight.
XPR-1 Problem: No sound is heard (all the LEDs are flashing red). Reason: The XPR-1 is in Protect mode, which indicates a Fault condition. • • • Switch the AC Power switch Off and On to clear the Fault condition. If the fault remains, look for a shorted speaker cable or damaged speaker. Check your sources and source connections (a bad interconnect, DC on the input, or an otherwise bad source component can cause a fault). Problem: The Standby LED is red and the XPR-1 fails to come on when triggered.
