Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).

But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.

At AVStore, we provide you with a GST compliant invoice for every purchase.

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.
