Emotiva A150 Stereo Power Amplifier


The Emotiva A150 offers lots of performance and simple to set up.  The circuitry in the A150 features a heavy duty linear power supply, great sounding high-current short signal path Class A/B amplifier modules, a trigger input and output plus unbalanced audio inputs.  It also includes audiophile quality fault protection that’s completely transparent in normal operation, yet protects the A-150 and your other equipment from common fault conditions.



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.

Power Output (two channels driven)

75 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.1%; into 8 Ohms
150 watts RMS per channel; 1 kHz; THD < 1%; into 4 Ohms

Power Bandwidth (at rated power; 8 Ohm load)

20 Hz to 20 kHz (+ / – 0.07 dB).

Broad Band Frequency Response

5 Hz to 80 kHz (+ / – 1.8 dB).

THD + noise

< 0.02% (A-weighted); at rated power; 1 kHz; 8 Ohms

Signal to Noise Ratio (8 Ohm load)

> 120 dB (A-weighted); ref rated power.
