Emotiva BasX A11 – Power Amplifier
The BasX A11 is a great choice if you’re looking for a high quality power amp to pair with a pre/pro, like their MC1, to power all of the speakers in a 7.1.4 channel system. And, because the A11 provides so many channels of amplification in a single chassis, it also offers some other interesting options, like providing the channels you need to enable you to bi-amp the three big front speakers in a formidable 7.1 channel system.
The BasX A11 is an eleven-channel power amplifier that delivers 105 watts / channel into 8 Ohms and 140 watts / channel into 4 Ohms, all channels driven, with a rated THD+N of < 0.1%, and an A-weighted S/N ratio of <115 dB. The BasX A11 features a heavy-duty linear power supply, high-quality Class A/B amplification, transparent fault protection, and a trigger input and output. High quality industry standard unbalanced RCA inputs enable the BasX A11 to be used with almost any preamp or processor. Audiophile grade five-way speaker terminals accept banana plugs, spade lugs, or bare wires. These features combined allow the BasX A11 to deliver true audiophile performance and sound-quality at an amazingly affordable price.

Sound Quality First
- Designed first and foremost to sound great in all types of audio systems with all types of music.
- Special, high-current LCR channels for driving demanding main speakers with ease.
- Great sounding short signal path 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 Class H power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers, while also maintaining optimal efficiency and cool operation.
- 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.
- Remote trigger input and output allow the BasX A11 to control and be controlled by other trigger-enabled equipment.
- The BasX A11 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.
More Channels = More Flexibility
- By providing a full eleven channels in a single chassis, the BasX A11 offers the flexibility you need to explore more options, like bi-amping, or adding more height channels, without taking up a lot of extra space or making your wiring more complicated.
Stylish New Look
- Emotives redesigned front panel gives the new BasX A11 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.
