Very long wait for two months! finally reached!
Audio Design Associates MPA501 & MPS500 Former US Flagship Power Amplifier
In fact, the price can be.. but freight pits ah .. light shipping and packaging costs took 3,000 .. and then returned a tax .. how much the tax will not say
The purchase connection cannot be provided.. This gadget has been discontinued.. The official website has been replaced by two more niubility models in fact.. EBAY is not common.. There may be two or three units a year.. if you want to.. Really want to go to the point guard.. Or domestic income it.. Generally around 1.8-2W..
At that time, the seller's asking price was 1500USD, and then they could bargain. I also got a 1300 pass. But there is 150USD domestic shipping.. The machine is heavy and bulky.
Pro, this is a machine.. Some classmates thought that it was a pre-class + post-class, in fact, a class
Sexy PP, but there is no XLR, only RCA, and the speaker can only take the banana head.. In fact, the original factory has an interface, but that is too bad.. Really do not want to use, but my speaker line are banana head .. so ignore it:
In fact, after the stage used a few .. before the postings are also mentioned .. my first post is also the company's PTM-6150..150/250 watts of power, this MPA501 (this short for short It is obviously a lot higher than 6150.. However, the power is not very high (in the theater system) is also 250/450 watts.. but the material is still good .. this machine, add up to about 90 pounds It is not heavy nor light..
eBay good things sharing will Haitao second-hand home theater This posting is basic introduction to my active duty equipment, currently this ADA to PK is LEXICON's LX7 post-class.. The two are different company's former flagship product.. Inexpensive rhythm!
There is no such product on the ADA's product line.. If you have a row of words, it should be similar to the current flagship.
Let's go and say it first! First on the nude MPA-501
MPA501 (Pool Supply Section) uses a very large ring cow, 4 large capacitors, ADA's reservoir has been very adequate, the previous PTM-6150 can also use the power of the reservoir in the case of power off Reserve, work more than 10 seconds at normal volume, this station can be about 20 seconds.
You can see that: 47000uf.. used 8 such capacitors.. add up to 370,000 uf.. but I'm not good physics.. there is no concept for these .. but to play too many later stage, power amplifier According to the experience, this is the most abundant grade I have seen in the pond! Power consumption is very touching.. 3000 watts.. electricity charges ah ah
Close-up of beef cattle: I forgot to put the reference object.. But it should also be imaginable.. It's also quite big..
Buy back is 115V, PTM6150 with voltage switch .. this is not. But the original factory can be non-destructive change the voltage ..
The red rectangle is marked with 115V---230V, and then the first red circle jumps to the left.. The first red circle cuts off the two wires. It becomes 230V.. Understand voltage After testing the cow's secondary voltage, I changed it to OK. (My friends told me that he has experience. I'm a painter and I haven't studied physics.)
There seems to be an internal. Leakage switch and the like - - high current..
Next is the MPS500..
Huge cooling fins.. There are two fans.. will speed. .. but not very quiet .. a bit noisy .. some people will change this fan to replace .. but it seems that the computer voltage is not the same .. do not know whether it is 230V or 110V..
Only one photo of the circuit can only be shot by the camera. The camera is completely HOLD! Did not dare to remove it..
Two ass photos: MPA501 access to electricity.. And then through the four-port cable to the power reserve to the MPS500, this interface is relatively rare. The United States seems to have.. China is relatively small.. four feet with locking head, 30A..
EBAY has this kind of interface to sell.. Few in China.. The original factory should be the head and tail of Ho Po..
The internals are like this: What are the lines of the zero line live line?. Knowledgeable students come out and explain it..
Listening Sense: ada PTM-6150 in the impression, neutral, warm sound, a little delicate, but the medium frequency is thin, dynamic is not awesome, explosive force is also a hard injury.. B&K 200.7S2, thick, powerful, analytical can also, In fact, this is the one I've ever used. LEXICON LX7, strong sense of theater, explosive power, full IF, is the post-class I am currently in service, this MPA501, high current partial A design, delicate sound, Big dynamic performance is good, warm sound, intermediate frequency is obviously better than PTM6150, of course, this is not a level of the machine, to solve the problem of thin frequency in my system, but the sound is more delicate, it can be said that can Wennengwu, currently One of the most satisfying ones in the post.2W Yuan, this post-class price/performance ratio is also very high..
