EMOTIVA A-150 Stereo Power Amplifier

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 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 for years of reliable trouble-free service.

• Heavy steel 2RU 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 A-150 to control and be controlled by other trigger-enabled equipment.

• The BasX A-150 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.

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.

Circuit Topology

The BasX A-150 is a two channel power amplifier. The BasX A-150 combines classical audiophile amplifier architecture, based on a heavy-duty linear power supply, and a carefully designed high current short signal path Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price.
