Emotiva BasX A2 Stereo Power Amplifier

The BasX A2 is a two channel power amplifier that delivers 160 watts / channel into 8 Ohms and 250 watts / channel into 4 Ohms, with a rated THD+N of < 0.02%, and an A-weighted S/N ratio of 112 dB. The BasX A2 features a heavy-duty linear power supply, high-quality Class A/B amplification, transparent fault protection, and a trigger input and output. The BasX A2 also offers a convenient feature that allows the amp to switch on when an audio signal is detected at its input - which is especially useful if your preamp or receiver doesn't offer a trigger output. High quality industry standard unbalanced RCA inputs enable the BasX A2 to be used with almost any preamp or processor and audiophile grade five way speaker terminals accept banana plugs, spade lugs, or bare wire. These features combine to enable the BasX A2 to deliver true audiophile performance and sound quality at an amazingly affordable price.

The BasX A2 the ideal amplifier to serve as the foundation of a great sounding stereo system, to power the front main speakers on a surround sound system, or to upgrade the front left and right channels of your favorite surround sound receiver.

Sound Quality First

• Designed first and foremost to sound great in all types of audio systems with all types of music.
• Great sounding Class A/B output stage ensures smooth, detailed sound and incredibly natural imaging, without a trace of harshness or strain.
• Low noise, wide bandwidth design, and a highly optimized input stage, lets you hear everything your high definition sources have to offer.
• Totally stable with real world speakers in real systems; not just on a test bench.

Solid Engineering And Quality Construction

• A heavy duty linear power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers.
• Top quality parts and construction throughout deliver years of reliable trouble-free service.
• Heavy steel chassis with milled aluminum faceplate offers strength and rugged good looks.
• Double sided FR4 circuit boards, with plated-through holes, help optimize signal paths and minimize the need for point-to-point wiring.

Flexible Signal Connections and Power Options

• Unbalanced inputs via industry standard RCA connectors accept all standard unbalanced interconnects.
• Heavy duty insulated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.
• Auto-On input sensing
• Remote trigger input and output allow the BasX A2 to control and be controlled by other trigger-enabled equipment.
• The BasX A2 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and will automatically detect and configure itself for the proper line voltage.

Stylish New Look

• Our redesigned front panel gives the new BasX A2 a sleek modern aesthetic that fits well with virtually any room décor.

Strong Yet Silent System 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.
• Full three-year warranty ensures that you'll be able to enjoy your BasX power amplifier for years to come.
