Product Description

Emotiva BasX A-300 is a two-channel power amplifier that offers true audiophile sound quality at an affordable price. The BasX A-300 includes a carefully chosen set of important features, including a heavy-duty power supply, high-quality Class A/B amplification, transparent audiophile-quality fault protection, a trigger input and output, and industry standard unbalanced audio inputs.

At a Glance

The BasX A-300 delivers 150 watts RMS per channel at less than 0.1% THD into 8 ohms; THD+N of less than 0.02%; and a signal to noise ratio of 120 dB referenced to full power. This makes the BasX A-300 the ideal amplifier to serve as the foundation of a great sounding stereo system or to power the important front main speakers in an excellent sounding surround sound or home theatre system.

Sound Quality First

Designed first and foremost to sound great in all types of audio systems with all types of music, A-300 is a great sounding Class A/B output stage ensuring smooth, detailed sound and incredibly natural imaging, without a trace of harshness or strain. Low noise, wide bandwidth design lets you hear everything your high definition sources have to offer.

Solid 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 for years of reliable trouble-free service. A heavy steel 3RU chassis with milled aluminium faceplate offers strength and rugged good looks while double-sided FR4 circuit boards with plated-through holes help optimise signal paths and minimise the need for point-to-point wiring.


You don’t need to be rich to afford BasX components, and you don’t need to be an engineer to figure out how to use them. They’re carefully crafted to give you many years of reliable and trouble-free service, and they’ll look great in your living room or on your audio rack. You can build a complete music system out of our BasX components that will give you a true audiophile listening experience. Or try adding one or two BasX components to round out your existing audio system.

Flexible Connections

A-300 offers unbalanced inputs via industry standard RCA connectors which accept all standard unbalanced interconnects. The 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. The remote trigger input and output allow the BasX A-300 to control and be controlled by other trigger-enabled equipment. It is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and automatically detects and configures itself for the proper line voltage.

BasX Simplicity

While the BasX A-300 offers lots of performance, you won’t need an advanced degree to install and use it, and you won’t need to rewire your home. The BasX A-300 ships with a removable heavy-duty industry standard IEC power cable. Just plug it into an outlet, connect to your preamp or processor and speakers, and you’re done.

Your BasX A-300 will figure out your line voltage automatically, and its speaker outputs are heavy-duty five-way binding posts that accept bare wire, banana plugs, or spade lugs. The industry standard connectors allow upgrades to the power cable or speaker wires; while it's not needed, BasX A-300 is ready if you want to add it later.
