They aren't that good, my friend even stopped carrying them 'cause of too many customer complaints and returns. Crown amps is the way to go, just let me know what your budget is and what kind of power(watts) are you looking for. Crown carries a full line of amps ranging in price from 249.99 for XLS series to over $4000.00 USD each for contractor or studio reference series amps. Crown amps produce clear, crisp, rich sound, that no other amps in their respective class can touch. |

its either a qsc or crown amp.... ive heard cases where ppl say qsc sounds better...
but i own a crown ce1000 my self, well built, adequate sounds, no problems yet |

The CE-Series of Crown amplifiers are professional tools designed and built for professional use. Engineered and manufactured by the same teams who built Crown’s acclaimed Macro-Tech® and KSeries amps, the CE 1000 has the rugged heart and soul that have characterized Crown’s amplifiers for over 30 years. With many of the same controls and features you’ve come to expect from Crown, CESeries amplifiers feature front-panel detented level controls, useful function indicators, proportional fan-assisted cooling, shortcircuit protection and more.
For superior flexibility, Crown CE-Series amplifiers can work with a range of Crown SST (System Solution Topologies) modules which provide true professional features like fixed-point crossover and summed bass output.
With a powerful, reliable performance, CESeries amps easily handle real 2-ohm loads and are capable of chest-thumping lows. Plus, your investment in an CE-Series amplifier is backed by Crown’s unequaled Three- Year, No-Fault, Fully Transferable Warranty that covers everything.
Features
Accurate, uncolored sound with very low distortion for the best in music and voice reproduction.
Bridge-mono/stereo mode switch allows you to set up your amps/speakers in the configuration that best suits your needs.
Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, highfrequency overloads and internal faults.
Extremely versatile, handling a wide range of speaker impedances and outputs.
Switchable input sensitivity.
Proportional speed fan optimizes cooling efficiency.
Shallow rack depth. Only 12.25 inches deep!
Choice of Speakon®, binding post, or barrier strip outputs (Speakon® comes standard).
Choice of balanced 1/4-inch (6.35-mm), XLR, or barrier strip inputs.
The best Three-Year, No-Fault, Fully Transferable Warranty in the business! It even covers round-trip ground shipping in the U.S. for all warranty work.
Specifications: Note: All measurements relate to 120-volt, 60-Hz units in Stereo mode with 8-ohm loads and an input sensitivity of 26- dB gain at 1-kHz rated power unless otherwise specified. Specifications for units supplied outside the U.S.A. may vary slightly at different AC voltages and frequencies.

| Hey most of these crown amps are pretty noisy. The qsc is only at 0.1 thd. |
|
|
| DJ Tranz |
That really doesn't mean anything! Crown amps are way clearerand cleaner,sharper sounding, more reliable, much better built, and like I said before, they are top choice in their respective classes.
Don't get me wrong, QSC amps are OK, but way too many complaints and returns and two big online stores, including my friend's online store, stopped carrying them. |
