About the A100 mkII
The Emotiva A-100 mkII is a stereo amplifier designed to provide high-quality sound with a solid power output of 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms, suitable for driving most modern loudspeakers. It operates in Class A/B with a heavy-duty linear power supply and an oversized toroidal transformer to deliver ample current for demanding speakers. The amplifier features a short signal path for high current, unbalanced RCA inputs, and audiophile-grade 5-way binding posts for speaker connections. It includes a front-panel machined aluminum volume knob surrounded by an illuminated ring indicating power and fault status. The A-100 mkII supports flexible power options including a 12-volt trigger input and output, and can auto-sense incoming audio signals to power on automatically, making it ideal for remote zone applications. It also offers a headphone output that uses the main speaker amplifier stage (with internal jumper configuration) to deliver high power to headphones safely. The unit is housed in a rugged steel 2RU chassis with a milled aluminum faceplate, measuring 8.5" wide x 3.125" high x 15" deep and weighing approximately 11.8 lbs. It is built with quality components and double-sided FR4 circuit boards to optimize signal paths and reliability. The frequency response is 20 Hz to 20 kHz ±0.08 dB at 1 watt, with a signal-to-noise ratio greater than 110 dB (A-weighted). Input sensitivity is 600 mV, and input impedance is 27 kOhms. The amplifier is protected against common faults, with status indication via the illuminated ring. It supports 115 or 230 VAC line voltage (switch selectable).
