Description
The Emotiva BasX A2+ Two Channel Power Amplifier is engineered to deliver high-performance audio with impressive power, clarity, and reliability. It provides 160 watts per channel into 8 ohms and 250 watts per channel into 4 ohms with both channels driven, ensuring strong and consistent output even in demanding listening environments.
With a rated THD plus N of less than 0.02 percent and an A-weighted signal-to-noise ratio of 112 dB, the A2+ delivers exceptionally clean and detailed sound. Its core design includes a heavy-duty linear power supply built around an oversized toroidal transformer and a refined Class A/B output stage that maintains precision across a wide dynamic range.
Audiophile Grade Construction and Expanded Connectivity
A major enhancement featured in the Emotiva BasX A2+ Two Channel Power Amplifier is the addition of balanced XLR inputs for both channels, greatly improving compatibility with higher-end preamps and processors. These join the existing unbalanced RCA inputs, making the amplifier suitable for a wide range of systems.
High-quality five-way binding posts allow secure speaker connections with banana plugs, spade lugs, or bare wire. Every component, from the power supply to the output stage, has been selected to maximize performance while maintaining long-term durability. The amplifier also includes trigger input and output connections for seamless integration with automated systems, ensuring consistent and convenient operation in any setup.
Versatility for Two-Channel, Surround, and Multi-Zone Applications
The Emotiva BasX A2+ Two Channel Power Amplifier excels in almost any configuration where strong and reliable two-channel power is needed. It works beautifully as the foundation for a dedicated stereo system when paired with a DAC or stereo preamp. It is also an ideal upgrade for the front left and right channels of a surround receiver, allowing the main speakers to perform at their full potential.
For installations that include a second zone, the A2+ provides clear and powerful audio that matches the quality of the primary listening area. This flexibility makes it suitable for both beginners entering high fidelity audio and experienced users refining a larger system.
Premium Components and Rugged Exterior Build Quality
Inside and out, the Emotiva BasX A2+ Two Channel Power Amplifier is crafted with durability and performance in mind. The chassis is constructed from heavy-gauge steel with a machined aluminum faceplate that offers both strength and refined aesthetics. Internally, the amplifier uses high-quality circuit boards, carefully routed wiring, and precisely chosen electrical components that ensure stable performance across many years of use.
These elements contribute to the A2+ maintaining its sonic integrity under real-world operating conditions, including extended listening sessions and demanding speaker loads. Every detail reflects Emotiva’s commitment to building equipment that combines audiophile performance with long-lasting construction.
Flexible Power Operation and Intelligent Control Features
The Emotiva BasX A2+ Two Channel Power Amplifier is designed to operate internationally and automatically adapts to either 115-volt or 230-volt AC power. It includes a standard trigger input for synchronized system power control and also offers an automatic signal sensing option that activates the amplifier when audio is detected on an input.
These features make setup simple and convenient, reducing the need for manual power switching. The combination of adaptable voltage, trigger functions, and intelligent monitoring ensures that the amplifier behaves predictably in a wide range of installations. Users can trust the A2+ to operate smoothly and consistently in everyday home theater or stereo configurations.
Stable Operation with a Wide Range of Speaker Loads
The Emotiva BasX A2+ Two Channel Power Amplifier is engineered to perform reliably with virtually any conventional loudspeaker. It maintains full stability with both 8 ohm and 4 ohm speakers, allowing it to drive a wide variety of modern and legacy designs. Its high damping factor and wide power bandwidth contribute to tight bass control, precise transient response, and overall clarity.
Whether the speakers are bookshelf models, floor-standing towers, or part of a multichannel system, the A2+ provides clean and dynamic power that enhances musical detail and cinematic impact. This broad compatibility ensures that users can confidently pair the amplifier with new or existing speakers without concern for mismatch.
Comprehensive Connectivity and Refined Circuit Topology
The Emotiva BasX A2+ Two Channel Power Amplifier offers both balanced XLR and unbalanced RCA inputs for each channel, ensuring flexibility with a full range of audio sources. Output connections are supported by audiophile-grade five-way binding posts that guarantee solid and reliable contact with any speaker cable type.
Internally, the amplifier uses a classical Class A/B topology supported by a robust linear supply and monitored by advanced microprocessor-controlled protection circuitry that maintains safe operation without affecting audio quality. With detailed specifications including a frequency response from 5 Hz to 80 kHz, gain of 29 dB, and impressive signal-to-noise performance, the A2+ delivers precision and authority that exceed expectations for its price category.
