Tapco J1400 Juice Power Amp

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.

channel@2ohms these amps save valuable rack space without compromising power output. HIGH CURRENT TOROIDAL TRANSFORMER A high-current toroidal transformer saves rack space and minimizes hum and noise. EXCELLENT SOUND QUALITY The low T.H.D.(0.05%) and high damping factor (400 or higher) gives excellent sound quality. 2 STAGE POWER SUPPLY The high-power units (L1800 and L2400) have a 2-Stage Class-H design that maximizes their performance. EQUIPPED WITH 30Hz or 50Hz HPF All amplifiers are equipped with high-pass filters on each channel to help maintain sound quality, yet help protect the loudspeakers. EXTENSIVE PROTECTION CIRCUITS Extensive protection circuits monitor over voltage/current conditions, overheating, output shorts, and DC voltage to improve performance and reliability. CLIP-LIMITER CIRCUITS Clip-limiters on each channel are provided to help prevent distortion due to excessive signal levels. L.E.D FUNCTION DISPLAYS Power, Clip limiter, Signal, Protection, Mode (Parallel/Stereo/Bridged) LEDs on the front panel indicate the status of the unit in operation.
