XPR-1

About the XPR-1

The Emotiva XPR-1 is a monoblock power amplifier designed for audiophiles seeking high power and clean sound. It delivers 1000 watts RMS into 8 ohms and 1750 watts RMS into 4 ohms. The amplifier features a fully balanced differential Class A/B topology with a Class H modulating power supply, utilizing a 2.5 kVA toroidal transformer and a 240,000 µF capacitor bank for stable, high-current delivery. It employs 36 output transistors in a triple Darlington output stage and uses precision metal film resistors and low ESR film capacitors on multi-layer glass epoxy PCBs. The power supply capacitors are distributed to optimize transient response and minimize ripple. The front panel includes dimmable LED meters with configurable orientation and brightness. Protection circuitry monitors temperature, shorted speaker connections, and ground faults, controlled by an ARM-7 microprocessor. The amplifier weighs 99 pounds and measures 9.5" H x 17" W x 19.5" D. It supports universal AC line voltage (115/230 VAC auto-switching) and requires a dedicated 20 amp circuit for optimal performance. The XPR-1 is known for its combination of power, precision, and value,
