5.0 out of 5 stars I love it so much..., 3 Mar. 2013
Verified Purchase(What is this?)
This review is from: Behringer K1800FX Ultratone 180W 4 Channel PA System (Electronics)
...I'm buying another one. This looks quality. It has a very attractive finish, like black carpet all around the cabinet. It's feature packed with a seven band equalizer and 100 digital FX including reverberation and echo delay to name a few. It is primarily a P.A and keyboard amplifier. The four input have left and right 1/4 inch jack sockets although this is a mono amplifier, it has a stereo link socket again 1/4 inch jack which allows you to "link" this amplifier to another amplifier to attain a true stereo image. I'm using it with my Roland Juno Stage synth. The sound, to my ears is excellent and will be even better after I've purchased the second one for stereo reproduction. There has been questions raised concerning the output wattage of this amplifier. I can say for sure that the 180 watts advertised is certainly NOT a RMS rating. For the layman; RMS is a mathematical equation that stands for "root mean square". It is the only true way of evaluating an amplifiers performance power. It's like an oscillator in a keyboard playing a note like a sine wave (without any form of modulation). The waveform will have a constant pitch and volume. PMPO (Peak Music Power Output) is another way manufacturers rate their product because the wattage rating is higher and it looks good for the punters. The big but is, when music "peaks" at a high volume, it induces harmonic distortion and other nasties. If an amplifier is rated at say 100 watts RMS, the prospective purchases knows he can get 100 watts before any noticeable distortion kicks in. Also watts do not necessarily mean higher volume levels; a 4 ohm speaker on a similar amp will give a higher volume than a 8 ohm speaker will at the cost of strain on the output transistors of the amplifier.

For the price IMHO I think this amp is a bargain. It looks good, performs good and is worth 5 stars. It may not suit everyones' needs but for me, it's a gem.
