Overview

Featuring the same pro features as the rest of PLX2 Series power amps and plenty of punch. But the PLX1804 comes at a friendlier price for those who don't need bridged or 2-ohm operation. Designed to power one or 2 speakers from each amplifier channel (4 ohm minimum loading) it offers a simplified feature set while retaining genuine, uncompromised PLX performance and technology. Weighing just 13 pounds this "plug-and-play" amplifier is perfect for ultraportable rigs, as well as reference-quality playback.

Very lightweight. Advanced cooling with flow-through heat sinks and front exhaust; front-panel LED power, clip, -10dB, and signal present indicators; Speakon outs; 21-position front-panel gain controls; balanced XLR inputs with TRS connectors; and patented PowerLight power supply technology combine to make the PLX1804 one of the most versatile andpower amp available.

Clip limiting protects speakers while thermal limiting maintains operation even during abnormal overloads.

900W/ch @ 4 ohms, 600W/ch @ 8 ohms.

Simple,Light, and Poweful!

By DJ SOKIN

from Long Beach, CA

Comments about QSC PLX1804 Lightweight Professional Power Amplifier:

Have have two dual Yamaha 15's and these speakers are power hungry. At 900 watts in a 4ohm rating, it feeds my speakers what it needs. I had this amp for about 3 months giging and it really helps my back due to its light wieght. I have used other amps and this amp is the best amp although without the other features. Its a simple plug and go amp with the power needed to shake the dance floor! recommend to my friends for sure.

Not Dead from a Dead Short

By Paul from Texas

from Austin/San Antonio, Texas

Comments about QSC PLX1804 Lightweight Professional Power Amplifier:

I cannot say enough about this amp. Not only does it deliver incredibly clean power from an ultra-light chassis, it is also tough and resilient. This past weekend, I was playing indoors, but the weather outdoors was perfect, and there were a lot of folks both inside and outside. I decided to use my monitors as my indoor system, and move my other speakers outdoors. I routed the speaker cables through a metal door casing, and thought I had enough clearance to keep the cables from fraying. Unfortunately, I was wrong, and after an hour or so of staff going in and out and closing and opening the doors, the cables frayed and shorted on the metal door frame. It was about 20 minutes or so when I noticed that there was warm, then HOT air coming out of my PLX 1804. The fan was blowing max, and the whole corner of the room was heating up. I shut the amp down when I realized what had happened. Since it was near quitting time anyway, I left everything to cool down. When I showed up the next day to pick up my equipment, I was amazed to find that the amp powered right up and worked perfectly! I've always owned monster Crown amps, but this amp has changed my mind forever. I can't think of a more clean, lightweight, powerful and bullet-proof amp on the market today. I'd guess the amp ran 20 minutes into a dead short!!! QSC has won me over!!!

Amazing performance! Perfect for mobile DJs!

By DJ Tommytoony

from Ann Arbor, MI

Comments about QSC PLX1804 Lightweight Professional Power Amplifier:

Played with the idea of getting a set of powered speakers, but couldn't bear to part with my EV SX-300's...then I found this. Amazingly lightweight and easy to transport. The sound is amazing...better than the Crown amp I had to replace (not to mention the QSC is MUCH lighter). Excellent, full sound, kicking bass. I've had this amp for 3 years now; it's taken a beating (as any mobile DJ's gear will) and it has never failed. Hell, it's never even gotten too warm! I cannot recommend this amp enough. Look no further...this is all you need.

Best Affordable Amp on the Market

By theBeeOBee

from Tobyhanna, Pa

Comments about QSC PLX1804 Lightweight Professional Power Amplifier:

I bought the plx1804 because of the price, weight, and power. You will be hard pressed to find this kind of power for this price and you also get Qsc's 6 year warranty. It also only weights like 13 pounds, and a lot of my musician friends are in shock when they pick it up...they are used to lugging around inferior amps that weigh over 40 lbs. There reason this is cheaper than some of the other plx amps is because it only does 4 ohms and 8ohms, can't be bridged, and doesn't include some of their built in filters (which are obsolete for me anyway...i use a dbx driverack). But if you aren't going to need those features, there is no reason to pay for them anyway. This amp is perfect for people that are looking for a plug and play system that has tons of power and they want the qsc reliability and sound.

PLX1804 ROCKS!!!!!

By Jerryc60504

from Chicago

Comments about QSC PLX1804 Lightweight Professional Power Amplifier:

I'm a mobile DJ and purchased the PLX1804 to power my Peavey SP5's. Let me just say that I this amp totally ROCKS!!!! I was powering my speakers with a totally sub-par Crown Amp and I'm glad I spent the extra bucks for the QSC and believe me, I won't own any other brand for as long as I'm in the business. Forget about the sound I'm getting out of this QSC, the thing is as light as a DVD player!!! Not only does this amp kick my speakers with awesome bass and headroom to spare, I'm not breaking my back carrying it back and forth to my gigs. This amp is a real winner!!!!
