This is the amplifier which I have used time and time again for a large range of applications. Street price on this amp is around $429, ranging from $400-$450 area depending on the place of purchase. It is a heavy amplifier weighing in at about 40lbs., and takes up two rack spaces inside your deep rack. The specs show the amp output of about 1400 watts max at 4 ohms bridged, meaning you can get roughly 1400 watts if you chain two 8 ohm loudspeakers together.
I have to admit that my experience with this amplifier has been typically using it outside of it’s realm of stated specs. I typically use it in a 2 ohm bridged mono setting, with two 4 ohm loudspeakers probably approaching the 1900 watt area of output. I must stress that this is not the intended use of the amplifier and should be done so at your own risk. I have yet to find a spec of the actual output of the amp at this rating as it is not rated to do so.
This all being said, the amp works great in this way. I have it paired typically with two JBL SRX speakers or two Peavey TLS 4X speakers running in chains, and get great results every time. The amplifier comes with clip limiters and filters, giving you plenty of pushing power without damaging the amp. Clipping is a bad thing meaning something is being driven too hard, and the limiter is a great way to protect your pricey gear.
These things are built like tanks, and I have seen them survive being dropped, kicked, blown fuses, power surges, rain and hail storms, freezing temperature….the list goes on. They just keep working. You may have to clean the knobs once in a while for dirt on the contacts, but that’s a small maintenance item that should be done anyways.
As I stated before, these amps are heavy. Carrying more than one at a time can be a pain the….uhh…..back. 40lbs. may not seem like much until you carry them back and froth multiple times in a gig. QSC does make a lighter amplifier that performs great as well, the PLX series, but the price range is out of some budget musicans. If you can afford the $600-$700 price range per amp of the plx series, then by all means save yourself the weight and do so. For the rest of us, use a dolly whenever you can.
The amplifiers are typically the grunts of the P.A. setup. They give you the power to throw your voice great distance, and give volume to all of your other gear. A critical piece of equipment like this should be clean and quiet, and let the rest of your gear determine the end result of the powered sound. The QSC RMX 1450 does this with flying colors, and can take a beating while letting you shine. If you are looking for a fairly priced amplifier for your expanding rig, p.a. or stacked, check this great amp out.
