When it comes to power amps, it?s all about power, reliability and price. Thankfully, TAPCO?s J?1400?delivers on all fronts. In developing these amps, we devised a rigorous power amp test which was literally un-passable by dozens of name-brand amps on the market today. Our new Juice Series passed the test with flying colors. It?s pure premium. Midrange and highs are clean and dynamic. Bass is tight, clean and has the authority one would expect from larger, more expensive power amps.

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.
A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling. The integral soft clip limiter protects against damage to the connected loudspeakers. The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.
