Using DJ Amplifiers in Home Theater
Does anyone here have experience using DJ amplifiers in their home
theater? Is it recommended? Many DJ amplifiers seem to offer good bang for the buck. One thing I notice is that few provide rms power ratings. Should I assume that the power rating list is max power and that the actual rms is about 1/2 of that amount? Also, if DJ amplifiers are a feasible approach, what is the best way to connect them to RCA outputs? Do adapters exist for this? Thanks, bguidry |

In my experience, they lack clarity compared to good home audio equipment. Sound reinforcement equipment is intended to sound loud. The circuits are simple. Here it's important to distinguish with studio amps. There are many studio amplifiers of exceptional quality. Since both typically have balanced inputs, and many have fans, it can be hard to tell the difference. Hafler and Crown make very high quality amps. And Crown amps are used in expensive sound reinforcement apps. |

om Does anyone here have experience using DJ amplifiers in their home theater? Definitely. Is it recommended? It's recommended if you do it right, and are willing to make suitable adaptations. One thing to watch out for is the fact that many of these amps have fans. Amps with fans generally aren't such a good idea if you keep them near your listening location. They're not much of a problem if you keep your amps in a closet or outside the listening room. Many DJ amplifiers seem to offer good bang for the buck. You still get what you pay for, but you're buying out of a more pragmatic marketplace. One thing I notice is that few provide rms power ratings. You must be looking at junk, or not finding the right ratings lists. Good brands to look at include QSC, Hafler, and Crown. If you surf the vendor web sites, you'll find very detailed RMS power specs. Should I assume that the power rating list is max power and that the actual rms is about 1/2 of that amount? Better yet, surf the web for the actual professional spec sheets. Forget what you see in flyers and on tags in dealers. Also, if DJ amplifiers are a feasible approach, what is the best way to connect them to RCA outputs? If you want to do it right, you make some custom cables or have them made. If you want expeditious, but useful results, you just pick up some mono-1/4" to RCA adaptors at Radio Shack. Do adapters exist for this? For sure. The Radio Shack adaptors are 2 for under $4, last time I looked. |

I've definitely consider QSC and Crown, however, I've not encountered Hafler very often in my searching. Other brands that caught my attention were Nady, Samson, Peavey, and Behringer. The fan noise could be a problem as suggested. Since the concensus here seems to indicate going with the more pricey Crown or Hafler amplifiers, I think I will revert my focus back to obtaining a higher powerered Carver amplifier. I'm currently using one rated at 175watts rms X 2 at 4 ohms. I love the look of the Carvers with the two analog power meters on the front. I guess I'll keep scanning Ebay for good finds on these. Thanks for all the feedback to this post and two my previous posts about my Adire Tempest project. bguidry |

Your typical Crown, QSC, or Hafler would probably bury a Carver when it comes to difficult loads. I'm currently using one rated at 175watts rms X 2 at 4 ohms. Consider the fact that your typical Crown, QSC or Hafler has 4-ohm bridged ratings. That correspond to a 2 ohm load. I love the look of the Carvers with the two analog power meters on the front. I'd trade a really sensitive, accurate clipping light for fancy meters in a heart beat. |

Hafler

If you surf the vendor web sites, you'll find very detailed RMS power specs. Take QSC off the list. It's a testament to Arny's hearing difficulties. Othewise, I concur. I've definitely consider QSC and Crown, however, I've not encountered Hafler very often in my searching. David Hafler invented the Ultralinear tube circuit, which firmly enshrines him in the audio pantheon of greats. He became chief engineer of Dynaco, and went on to start Hafler. His second product was the DH-200, the world's first MOSFET audio amplifier. At the time, this amp was regarded as a price/performance breakthrough. Unassuming in appearance, it has massive heatsinks with very plain metalwork. It was followed by some extremely good preamps, and more MOSFET amps, some of which had a new circuit, the Excelinear. MOSFET amps are the most durable of all solid state amplifiers. They can drive any load without output damage, and if you're reasonably lucky, they will survive a dead short. The MOSFET transistor is now ubiquitous in power switching applications because of it's ruggedness. The sound of the traditional MOSFET circuit has both followers and detractors, to which I add my personal observation that they complement metal dome tweeters very well, but are not as good with fabric types. Another MOSFET circuit developed by Jim Strickland, founder of Acoustat, provides a different kind of sound that compliments fabric tweeters. I use both types of amplifiers in my systems, depending upon the speakers they match. At the time of it's introduction, the Acoustat TNT-200 was featured on the cover of Audio Magazine, and it was regarded by many, at that time, as raising the bar for clarity and detail in reproduction. When Rockford bought Hafler and Acoustat, they chose -- unfortunately, in my opinion, to preserve only one amplifier technology. Strickland's original design was hardened -- the original design had vulnerabilities that had nothing to do with output load -- and launched the 9000 series, and the P series professional amps. These are astonishingly small, extremely high quality amplifiers that are far tougher than the typical professional unit. Because they use MOSFETs, they have no relays or fuses, and in my opinion, have MUCH higher fidelity than the QSC units.

Nelson Pass's Threshold amplifiers can be found in some Nakamichi receivers, and are quite a pleasant surprise. B&K amplifiers use the traditional MOSFET circuit, with exceptional build quality.

If you surf the vendor web sites, you'll find very detailed RMS power specs. Take QSC off the list. It's a testament to Arny's hearing difficulties. Othewise, I concur. I've definitely consider QSC and Crown, however, I've not encountered Hafler very often in my searching. David Hafler invented the Ultralinear tube circuit, which firmly enshrines him in the audio pantheon of greats. He became chief engineer of Dynaco, and went on to start Hafler. His second product was the DH-200, the world's first MOSFET audio amplifier. At the time, this amp was regarded as a price/performance breakthrough. Unassuming in appearance, it has massive heatsinks with very plain metalwork. It was followed by some extremely good preamps, and more MOSFET amps, some of which had a new circuit, the Excelinear. MOSFET amps are the most durable of all solid state amplifiers. They can drive any load without output damage, and if you're reasonably lucky, they will survive a dead short. The MOSFET transistor is now ubiquitous in power switching applications because of it's ruggedness. The sound of the traditional MOSFET circuit has both followers and detractors, to which I add my personal observation that they complement metal dome tweeters very well, but are not as good with fabric types. Another MOSFET circuit developed by Jim Strickland, founder of Acoustat, provides a different kind of sound that compliments fabric tweeters. I use both types of amplifiers in my systems, depending upon the speakers they match. At the time of it's introduction, the Acoustat TNT-200 was featured on the cover of Audio Magazine, and it was regarded by many, at that time, as raising the bar for clarity and detail in reproduction. When Rockford bought Hafler and Acoustat, they chose -- unfortunately, in my opinion, to preserve only one amplifier technology. Strickland's original design was hardened -- the original design had vulnerabilities that had nothing to do with output load -- and launched the 9000 series, and the P series professional amps. These are astonishingly small, extremely high quality amplifiers that are far tougher than the typical professional unit.

"Arny Krueger" wrote Since the consensus here seems to indicate going with the more pricey Crown or Hafler amplifiers, I think I will revert my focus back to obtaining a higher powerered Carver amplifier. Your typical Crown, QSC, or Hafler would probably bury a Carver when it comes to difficult loads. "would probably"... how would you know, Mr. no-empirical-experiences? Given the rather conspicious reliable evidence that I've got considerable emperical experience with these and many other amps, one is tempted to ask what the heck are you ranting about, Powell? Krell, Levinson and others could be said to "bury" your biased picks, too. True, there's no theoretical limit to how much an amp can be underrated. I'm currently using one rated at 175watts rms X 2 at 4 ohms. Consider the fact that your typical Crown, QSC or Hafler has 4-ohm bridged ratings. That correspond to a 2 ohm load. Why is that relevant (bridging) to the poster's application/needs? See former comments about "difficult loads" and comment just above about "2 ohm load". RMS load rating is not the major determinant in high fidelity reproduction. So Powell, does that mean that your main system with speakers has power amps rated at 100 milliwatts, RMS? Of course not. There's at least a loose relationship between RMS power ratings and ability to drive speakers to useful volume levels. In fact there's no other spec that is vastly different, and more relevant. It is only one factor of many to consider. Name a commonly-used amplifier spec that is vastly different and also a better predictor of an amps ability to drive speakers to satisfying levels. I love the look of the Carvers with the two analog power meters on the front. I'd trade a really sensitive, accurate clipping light for fancy meters in a heart beat. Quack, quack, quack... So Powell, does that mean that given the chance, you took the fancy meters that impress visiting-firemen and small children? |
