Overview

If your speakers sound shy, it's because they don't have enough power.

The XPA-4 Gen3 is a 4 channel audiophile home theater power amplifier built on our XPA Gen3 modular platform, designed to bring more control and headroom to the channels that make surround sound feel immersive. Connect it to an AV processor, preamp, or an AV receiver with preamp outputs (RCA jacks usually labeled “PRE OUT”), and you can upgrade the performance of your surround, height, and ceiling speakers without replacing your whole system.

Inside, XPA Gen3 pairs an audiophile Class A/B output stage for clean detail with a regulated switch-mode power supply rated over 3 kW to stay stable when multiple channels demand power at once. Soft-Switch Optimized Class H operation helps it run efficiently while staying composed through dynamic peaks.

Start with four channels today, then expand later as your setup grows. Modules are installed by Emotiva (free with the purchase of new modules) or an authorized service center.

Common uses

• Power surround, height, or ceiling speakers with more control and clarity

• Upgrade an AVR’s effects channels for Dolby Atmos or DTS:X

• Start with four channels now, then expand as your system grows

Features

Sound Quality First
Designed first and foremost to sound superb in all types of audio systems with all types of music. Low noise, low distortion, wideband amplifier design with traditional Class A/B output stage ensures smooth, detailed sound, without a trace of strain or harshness. . Totally stable with real world speakers in real systems; not just on a test bench.
Modern Efficient Circuit Design
Optimized Soft-Switch Class H™ power supply topology delivers improved efficiency without compromising audio performance. Switched Mode Power Supply (SMPS) offers all of the performance of a traditional linear power supply, with improved efficiency and reliability, and reduced overall weight.
Quality Construction
Top quality parts and construction throughout for years of reliable trouble-free service. Heavy steel 4RU chassis with milled aluminum faceplate offers strength and rugged good looks. Solid machined gold-plated RCA input connectors provide a reliable connection with a wide variety of audio interconnects. Fully modular construction allows you to purchase as many channels as you need today, and then add more channels later when and if you need them. Designed, assembled, and tested in the U.S.A. at our plant here in Franklin, Tennessee
Flexible Signal Connections and Power Options
Gold plated five-way speaker binding posts with clear shields allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs. Choice of balanced or unbalanced input for each channel, independently controlled by reliable metal toggle switches. Remote trigger input and output allow the XPA-4 Gen3 to control and be controlled by other trigger-enabled equipment. World compliant AC line voltage operation enables the XPA-4 Gen3 to operate on any line voltage between 100 VAC and 250 VAC 50/60Hz. Standard IEC power inlet fits all standard IEC power cables and most custom audiophile power cables.
Protection
Audiophile-grade fault protection is entirely transparent under normal listening conditions, yet protects the amp and your other equipment from virtually all common faults. The XPA-4 Gen3 is protected from AC line faults by a rugged resettable rear panel push-button circuit breaker. Full five-year warranty ensures that you’ll be able to enjoy your XPA-4 Gen3 amplifier for years to come.

CIRCUIT TOPOLOGY

CIRCUIT TOPOLOGY: The XPA-4 Gen3 is a fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection. The XPA-4 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).

AUDIO SPECIFICATIONS

AUDIO SPECIFICATIONS: The XPA-4 Gen3 features three of our High-Powered Single Channel Modules. Audio Specifications (Four High-Powered Single Channel Modules):
Power Output: 300 watts RMS/channel; 20 Hz – 20 kHz; THD<0.1%; 8 Ohms; one channel driven 550 watts RMS/channel; 20 Hz – 20 kHz; THD<0.2%; 4 Ohms; one channel driven 300 watts RMS/channel; THD<0.1%; 8 Ohms; two channels driven 490 watts RMS/channel; THD<0.1%; 4 Ohms; two channels driven 260 watts RMS/channel; THD<0.1%; 8 Ohms; ALL FOUR channels driven 415 watts RMS/channel; THD<0.1%; 4 Ohms; ALL FOUR channels driven
Power Bandwidth (at rated power; 4 Ohm - 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.1 dB)
Broad Band Frequency Response: 5 Hz to 80 kHz +0/-2 dB
THD + noise: < 0.005%; at 100 watts RMS; 1 kHz; 8 Ohms
Signal to Noise Ratio (8 Ohm load): > 117 dB; ref FTC rated power; unbalanced input (A-weighted) > 91 dB; ref 1 watt; unbalanced input (A-weighted)
Minimum Recommended Load Impedance (per channel): 4 Ohms (one 4 Ohm load or two paralleled 8 Ohm loads)
Damping Factor (8 Ohm load): > 500
Input Sensitivity (for rated power; 8 Ohm load): 1.71 V
Gain: 29 dB
Maximum Power Consumption: 1,700 watts.
Note: The values shown refer to the amount of power the amplifier would consume while playing test tones continuously, on all channels, at full power, into a load bank. Therefore, they are not at all characteristic of what you would expect when playing music or the soundtrack from a movie. Normal audio signals are dynamic, so the amount of power they require from second to second varies widely, and the average is far lower than this. With normal content, even playing very loudly, one of our amplifiers will consume far less power than indicated in the chart, so these values should not be considered to be a circuit requirement for normal operation.
Input Impedance: 33 kOhms (balanced) 23.5 kOhms (unbalanced)

INPUT & OUTPUT CONNECTIONS

Input Connections (High-Powered Single Channel Modules): Unbalanced (RCA); balanced (XLR); one each per channel, independently selectable.
