If you wanna rock the house, you need the Juice!

Delivering pure premium power and reliability, the 800-watt J-800 stereo power amplifier is great for smaller coffeehouse gigs when amplifying a couple of guitars and a few vocals.

Pure Premium Power

This series of amps deliver gobs of power and maintain their high-quality sound for volumes ranging from quiet to cranked. With three models delivering 800, 1400 and 2500 watts of premium power amplification you're sure to find a Juice Series amp.

Features you can use

Sure, the Juice Series looks great, but who's going to see them in a rack on side of the stage? You will, that's who. That's why Mackie and Tapco added some nice extras to make your job easier. The front-panel includes a volume control and bright signal presence and overload LEDs for each channel. A tour around the back will reveal a mode select switch for mono/stereo/bridged mono operation, a 30Hz subsonic filter for eliminating the lowest of the low frequencies, plus a main breaker and clip limiter circuit for amplifier and loudspeaker protection. Balanced 1/4-inch and XLR inputs plus separate binding post and Speakon outputs for fast setup and no hunting for adapters.

Great for every application

Whether you're setting up for band practice in the garage, waking up at 5 P.M. to get to the club for tonight's gig, or at the club waiting for the bass player to arrive for sound check, you can count on the Tapco Juice J-800 amplification system to deliver exceptional sound quality without fail.

Solid amp, good performer

By Zippo the Heavier

This amp is nothing fancy, but it works well. Stock A/B topology is proven reliable. Massive transformer will deliver high current when needed. Protection circuit turns amp off if you hook it up wrong or do something else stupid. When the amp cools down, it wakes up good as new. It is a bit heavy, but the premium lightweight-topology and components cost more, so that is a fair trade for those on a budget. The sound is really fine for an amp in this price range, ten times better than most rock bands need. Good deal.


even better than expected

Picked these up to produce a keyboard centered fusion - jazz duo . Currently used this amp to power a pair of kustom kpc115s on poles with a powered nady ssw-15a sub. Added a set of gemsound piezo super tweeters to each side , yielding 300/side at 4 ohms. Result; great, clean sound. The best thing about this amp is the noice floor. No hiss. Will finish out this system with another 800 for monitors, and a 1400 to power a set of kustom kpc 215s. Done deal this setup will yield 450/side plus 300/side. More than enough with the powered sub and the keyboard players twin alesis sumo 300 amps(305w each) the juice series offers power ranges that are real-world usable in a very roadworthy package. Yeah, they are heavy but I would be skeptical about reliability if they weighed nothing. sound mountain productions.
