12 best power amplifiers

Power amplifiers are electronic devices used to increase the amplitude of electrical signals, particularly audio signals, to drive speakers or other loads with sufficient power to produce sound. They are an essential component in audio systems, including home theater setups and professional sound reinforcement systems. Here are some key aspects related to power amplifiers:

  1. Amplification: The primary function of a power amplifier is to amplify weak audio signals from sources like preamplifiers, mixers, or audio players to a level that can drive loudspeakers with sufficient power to produce audible sound.

  2. Types of Power Amplifiers: There are various types of power amplifiers, including:

    • Class A Amplifiers: Known for their high linearity and low distortion but are inefficient and generate a lot of heat.
    • Class B Amplifiers: More efficient than Class A but have crossover distortion when transitioning between positive and negative signal halves.
    • Class AB Amplifiers: A compromise between Class A and B, offering good efficiency and sound quality.
    • Class D Amplifiers (Digital Amplifiers): Highly efficient and compact amplifiers that use pulse-width modulation to reproduce audio signals.
    • Class H Amplifiers: Combine aspects of Class A and Class AB amplifiers to improve efficiency without sacrificing audio quality.
  3. Wattage and Power Ratings: Power amplifiers are rated in watts (W), and their power output determines how loud they can drive speakers. The higher the wattage, the more power the amplifier can deliver to the speakers.

  4. Impedance Matching: It's crucial to match the amplifier's output impedance to the speaker's input impedance for optimal power transfer and sound quality.

  5. Bridgeable Amplifiers: Some power amplifiers are bridgeable, allowing you to combine two channels into one with higher output power for driving large speakers or subwoofers.

  6. Mono, Stereo, and Multichannel: Power amplifiers come in various configurations, including mono (1 channel), stereo (2 channels), and multichannel (typically 4, 5, or 7 channels). Multichannel amplifiers are commonly used in home theater systems to power multiple speakers.

  7. Input and Output Connections: Power amplifiers typically have both balanced (XLR) and unbalanced (RCA) inputs, and they connect to speakers via binding posts or speakON connectors.

  8. Heat Management: High-powered amplifiers generate heat, so many come with built-in cooling fans, heat sinks, or other cooling mechanisms to prevent overheating.

  9. Rack-Mountable: Some power amplifiers are designed for professional audio applications and can be mounted in standard 19-inch equipment racks.

  10. Protection Circuitry: Modern power amplifiers often include protection features such as overcurrent protection, thermal protection, and short-circuit protection to prevent damage to the amplifier or speakers.

  11. Use Cases: Power amplifiers are used in various audio systems, including home theaters, stereo setups, live sound reinforcement, recording studios, and concert venues, to provide the necessary power to speakers and ensure clear and loud audio reproduction.

Power amplifiers are a critical component of audio systems, ensuring that audio signals are delivered with sufficient power to create sound that can be heard and enjoyed.The choice of amplifier depends on the specific requirements of the audio system and the desired audio quality.

User questions & answers

Question: What is rms of this amp
Answer: I emailed behringer and they said to multiply the peak power rating by .7 and that gives you the rms rating. So this amp give 2,100 watts rms at 4 ohms and 1,100 watts rms at 8 ohms
Question: What is the watts rms at 8ohms per channel
Answer: 2 x 1600 watts 8 Ohms peak
Question: This amplifier can run into 240v input
Answer: No
Question: Is this amp similar to the I nuke
Answer: Hi, It is an improvement over the I-nuke. I use the 6000's and each makes full use of a 120V power source (you can not get more than that out of anything that plugs in) at high levels. The improvements lead to better speaker protection and lower distortion. -R

Answer: should work ,have almost the exact plug cord
Question: How loud is the fan? I want to use this in a home theater to drive a pair of subwoofers
Answer: They tell me there is a cooling fan ... but I certainly can't hear it.The old heavy analog Crown amps definitely had loud fans but this one is very quiet.
Question: How many watts, and at how many Ohms
Answer: http://www.crownaudio.com/en/products/xls-25021200W @ 2 Ohm775W @ 4 Ohm440W @ 8 Ohm Dual2400W @ 4 Ohm Bridged1550W @ 8 Ohm BridgedPlease consider Affinitech Inc. if you decide to purchase.Thanks!
Question: Does the cooling fan run all the time or just when pushed hard
Answer: Kurtis is correct. You will never hear this fan run unless you mute everything, furnace turns off, you silence all clocks and don't have a mini fridge running. Without the blue lights, you only know it's on if the attached speakers play. Pushed it to near clipping just to see and not a peep from the fans.

Crown XLS1502

Crown's new XLS DriveCore 2 series of power amplifiers feature an upgraded look with a larger display. Like their predecessors, the new XLS amps are equipped with Crown's patented DriveCore technology. The XLS1502 can drive your speakers with 525 watts (at 4Ω bridged) of clean power with very low distortion.

DriveCore

This new amplifier technology seamlessly integrates the amplifier drive stage into the power output stage fusing everything into a chip the size of a dime. The foundational DriveCore circuitry is based on breakthroughs by Crown's own Gerald Stanley with five patents applying to the advanced feedback, modulation and output stage technologies. DriveCore's front-end drive circuits leverage the inherent efficiency of Class D output stages while also maintaining superb sonic characteristics. The end result is an ultra-efficient one-piece audio amplifier circuit that exhibits the exemplary audio quality of a highly evolved Class AB design.

Class-1

Class-I, also known as BCA (Balanced Current Amplifier) is Crown’s patented, cutting-edge technology that gets more power out of an amplifier with less waste than was ever before possible. Class-I technology offers several key advantages. It provides unprecedented efficiency, requiring less power from the AC supply than other designs and that can add up to significant cost savings over the life of the amplifier. Class-I handles reactive loudspeaker loads easily and gracefully, by reusing energy returned from the loudspeaker rather than dissipating it as heat or forcing the amp into premature current limiting.

User questions & answers

Question: Can you gig fine with this
Answer: Yes the power cord do have a mute button
Question: could you plug it into a speaker cabinet
Answer: Yes the software can be updated very easily at home. The Max 360c can even be updated through WiFi.
Question: Can it be plugged into a PA system for live performance
Answer: The screen could be brighter. Dont think the colors of arrows can be changed.
Question: How would this do for a practice amp for a Bass
Answer: I think that the 0.6 watts each measurement, 1.2 watt total must be a mistake, off by a factor of ten. I've tested them against my portable ten watt powered stereo speaker (five watts per channel). They're slightly louder than the portable speaker. I would bet money that these are six watts each, twelve watts total. I'm sorry I don't have a more sophisticated method of testing, but, no way are they just 1.2 watts total.

User questions & answers

Question: is it safe to hook up the sony ss-b1000 5-1/4 inch book shelfspeakers to this amp
Answer: Yes, assuming you hook them up correctly!. I have some 70's vintage Technics speakers running on it just fine.
Question: I hear "static" at low volume (definitely not the speskers). Any suggestions
Answer: Disconnect your input source to the amplifier. If the noise goes away, then it's coming from the source and not the amplifier. If the noise continues, disconnect all inputs. If you hear the noise, the problem is likely the amplifier.
Question: is there a way to hook up to a new flat screen tv to run a set of external speakers
Answer: You asked this a while ago, so I'm guessing you've found out by now. This receiver does not have HDMI or Optical inputs, only RCA inputs. Most new TVs no longer come with RCA out, but many have a headphone output. If your TV has a headphone output, you can get a headphone to RCA adapter and use that to connect to this receiver.
Question: Can I run an RCA cord from my TV to this amp? The input/output schematic does not show a TV
Answer: All 3 inputs are RCA, just pick one :) Just because it says "CD" or "Aux" doesn't specifically mean you must use that device, RCA is RCA. However, I wouldn't recommend purchasing it. Mine died (non smoking house, didn't overheat or push it too far) within 1 month of use. I decided to go with the Dayton Audio APA150, which has been a workhorse since day 1 with no issues and much better consumer ratings than this Pyle of junk. Happy hunting.

User questions & answers

Question: I have 2 speaker with 150W each,can I use with this amplifier (since it is 2000 W
Answer: It's best if you use speakers that can handle the output of the amplifier. Since the manufacture states 2000 watts, I think that they are telling us the that is the output at 2 ohms. I run a Peavey IPR 1600 at 8 ohms and my amplifier will only put out 300 watts per channel at 8 ohms. My amp will put out 560 watts at 4 ohms . It will produce 1600 watts at 2 ohms, however running a power amplifier at 2 ohms is hard on the amplifier. Its best to run speakers that are 8 ohms and you'll have clean and clear sound as loud as the amplifier will produce at 8 ohms. Less wattage clear sound.
Question: Can this handle .. rockville pbg18 18" passive 2000 watt 8 ohm pro audio subwoofer sub/mdf cabinet
Answer: This amp is not that powerful enough to handle 2000 watt 8 ohm. It can handle well below that
Question: whats the with and the lenght of this amp all around
Answer: 19x13x4
Question: How much noise does the amp create? I'm looking for a PA amp that needs to be very quiet in a small room
Answer: This is a noisy(double fans) amp. Don't get this one if you are seeking a quiet unit.

    User questions & answers

    Question: Its this model you are selling here 110v or 220v
    Answer: It's a 110v not a 220v.
    Question: Can I use it with only one speaker...Mono
    Answer: The amplifier does NOT have a bridged mono mode, so it will not put 600 watts out a single channel into a single speaker. However, with its built-in 100hz crossover, it can split a single channel into two separate HI/LOW channels (20khz->100hz)/100hz->20hz). The split channels could then be used to power a bi-ampable (300W HI/300W LOW) speaker. (Please don't try this if you don't know what you are doing.)
    Question: Which country is this made in
    Answer: I am not going to pull it out of my rack, the box says it is made in China. I am using it to power my home stereo and it works.
    Question: Is that 500 watts RMS
    Answer: Hi...Not sure what you are looking for..RMS is a term used to describe an average power rating or average AC voltage that is usable..the peak to peak stuff is more a math number to me. I went to Google.com and downloaded the QSC GX5 500 watt power amp. manual, Which.. is something I would recomend for you to do as well..the GXS is rated @500 watts per channel driven into an 8-ohm load per channel..The book doesn't mention RMS or Peak to Peak power..but since RMS is your usable power..I'm assuming this will be an RMS value. In the QSC manual, there is a contact # to talk to the QSC people directly.If you are looking for a little more power out..try using 4 Ohm load speaker system. The Amp is designed to power into a 4 ohm load..I have used my GXS unit with a nice graphic equalizer in front, which bumps up the pre-amp some and the output is very nice..no heat issues or noise that I can detect.BUT..Download the manual read it over, talk to the QSC people directly..tell them what you are trying to do..but again..this is a flat response amplifier, and you will want some sort of graphic eq. device in front for the sound I think you are looking for..good Luck..Be wellMave

    User questions & answers

    Question: Is it possible to power car subwoofers with this amp
    Answer: Yes it is. I have a 2.1 stereo in my house. I've been powering a JBL W12 GTi MKII with my xli 3500 for years. Of course the amp is in my house and not in a car.
    Question: Is this amp capable of driving 4 ohms - bridged mono? The manual does not specify
    Answer: No.ill get a class h power amplifier,1100 to 1200 watts a channel.that way you wont be no strain on the amp,wont have to run its full power,,risking of burning up your amp or speakers
    Question: will these crown xli series amplifiers work well for home theater use or would the fan noise be to much
    Answer: I am using it in a home theater application. There is no fan noise at all. The Crown XLI series amplifiers are a great choice when considering a pro amp for home theater use. After finally getting one I wouldn't even think of getting anything else.
    Question: watt speakers at 8ohms each. They are 360 watt peak each. Is this amp enough for these speakers. amp to speaker then spkr to speaker on ea ch
    Answer: The output of the XLI 800 @ 8 ohms is 200 W per channel x 2 channels=400W. In my opinion this model is not the proper size for 4 100 watt speakers. Upgrading to the 1500, would be a better match.

    Question: This amp + 2 jbl arena 130s. anyone have an answer as to why the distortion is quite bad at around 45-50% volume
    Answer: Most amplifiers with a 1 volt signal coming in the input will max out around 50 % on the volume control. After the amp is maxed, the sound will be distorted. Known as clipping. The extra control on your volume is fir a weaker signal in the input.
