I just got this and installed it. Can't give a review yet. Maybe put one on later, but so far, works fine.

Very powerful PA System Amplifier. This amp with run your electric bill up very quickly. It uses a lot of power. I'm running both channels to 2 separate custom 15" Eminence enclosures with passive crossovers, built in, through the EMB 48 channel outboard EQ, two 24 channel Mackie mixers, a DAC, to a Mac Mini and I can only turn the volume 2-3 notches from 0 at max, before the neighbors call the police. This amp would pair much better with a pair of 1000-2000 watt 15-18" passive PA system drivers.Overall a great bargain for the price. Very powerful, but draws a lot of current from the AC socket. For anyone of the previous reviews that stated the fans are too loud, they are audible but for the power that this amp produces you wont even hear once your system is at around 53db.

Once the 115V transformer was changed for one working from 240V it is fine. However, a straight 240V: 12V: 12V does not work and required some extra turns to be hand wound to achieve the open circuit voltage of 18V: 18V. A straight 240V: 18V: 18V winding gives too high an open circuit voltage. Once this bifilar winding of about 46 turns was added to the 12V: 12V to make 18V: 18V open circuit everything works well. The unit provides excellent performance at a good price. The morale is to make sure you have a unit for a working voltage of 240V. The units are available with alternative input voltages.

This review is geared towards a beginner, like I was before I got to know my system. Like the title suggests, you should buy this unit if you plan to tri-amplify your system. If you need help interpreting that concept, it means that your highs, mids, and woofers will all have their own amplifier, respectively.If you're picky about your sound like I am, you might even decide to take advantage of the subwoofer output for a full range (neighbor angering) sound. This is a mono channel, but if you're buying a crossover you should already know that won't effect performance negatively.This box gives you all of the right controls over the crossovers. It offers high, mid, low and subwoofer level controls, 30hz cutoff for the low and subwoofer channel, phase inversion for each channel, and two independent crossover points. One point will cut the high and mid frequencies and the other will separate the mid and low frequencies. The low and subwoofer crossovers will allow for some overlap if you want them to.I'll admit that I actually use this box for a bi-amplified system. To achieve this, I've set the mid/high point wide open to allow all mid/high frequencies. To protect my PDBT28 tweeters, I simply used the passive crossover that came with them in the box. With a little tweaking on the sound board's preamp, they sound just fine until I manage to install an equalizer in my line. If your primary input is a mobile device like a tablet or cell phone, you can also use the 6-band digital equalizers that are in the device's settings.
