发帖数: 16048 | 5 This is a vintage NAD 2200 power amplifier with a massive power supply and
puts out around 200 watts per channel into 8ohms. The amplifier will power
up and play music or produce very nice crystal clear sound. When the volume

is at an increased level of power, the protection circuit will come on.
Not sure why, maybe an easy repair? The unit is in good cosmetic condition

High current amplifier protection circuitry allows you to use up to 4 speaker pairs without damaging your amplifier.
High current resistors with aluminum finned heat sinks for maximum power delivery, up to 150 watts per channel.

应该就是普通的一分四，每个输出通道里面串联了一个电阻，
所谓的25W输出，指的是阻抗匹配时送到负载的功率，
考虑只有一个喇叭的情形比较容易，如果这个（8欧）喇叭串了一个（72欧）电阻，
首先，功放输出功率减少，因为有反射，然后这个喇叭拿到的功率是总输出功率的1/100.
再就是用一个输出口接四个喇叭的话，阻抗太不匹配，负载在1.5-2ohm，可能会弄坏功放。
为了保护功放，每个喇叭要串联一个15-25欧姆的电阻，这样满载时候输入阻抗就回 |

发帖数: 4285 | 12 不佳的回答有包子没？
1，1202FX是个混响，虽然可能接耳机，但它本身没有推动音箱的功率放大部分，所以
你需要一个receiver或者合并功率放大器（integrated amplifier)来放大1202FX输出
的声音信号以推动音箱，这俩东西本质没什么区别, receiver带听广播的收音头而已。
如果1202FX能控制输出音量，你可能只需要一台功率放大器（power amplifier）就够
了。
2，建议你到EBAY或者audiogon上搜搜这三样东西，先有个主管印象，就好办了。
这两

发帖数: 1334 | 13 I totally agree with your comments here. That's why we always want to buy
amplifiers with high output power ratings, even though the majority of the
time the average output power is usually on the order of a few watts, and
the 100 or 200 watt peak power might last for just a few seconds. I saw
people using 1000 w monoblocks to push speakers with 250 W rating. As long
as one is careful with the volume control, there is never too much power for
an amplifier. |

So, in this case, which one is better in term of audio quality:
(1) YAMAHA higher model rx receiver, I will only use pre-out
(2) NAKAMICHI entry level receiver
in case 1, I will put a power amplifier after front end. In case 2, can I
save the power amplifier.

发帖数: 316 | 28 Suppose the impedance of your speaker is 4 ohms, and its Continuous Power
Handling is 100 W. If you are playing light dance music, the amplifier's 4-
ohm power should be 1.6 x 100 W or 160 W continuous per channel. To handle
heavy metal/grunge, the amplifier's 4-ohm power should be 2.5 x 100 W or 250
W continuous per channel.

发帖数: 2005 | 29 In general speakers don't have "power supply". The receiver sends both the
signal and the power to the speakers through speaker cables (i.e. sending
the amplified signals to the speaker).
Sub-woofer often have their own amplifier built-in, which will have voltage
problem.
Receiver does have voltage problem. |

Polk Audio RTi12，$299 each
http://www.frys.com/product/6895346
准备就此买receiver and/or amplifier.
由于RTi12的power是50-500W，研究了网上的各种评论得到结论：要发挥RTi12的best
performance，最好买receiver + external amplifier。一个推荐组合是：Onkyo TX-
NR828 + Emotiva XPA-3. 但，太豪华了不是？
能不能简单点买个Onkyo TX-NR727 at $449? (110W each channel at 8 Ohms) 普通大

BMB配置的：
BMB DAS-300 (SE) 600W 4-Channel Karaoke Mixing Amplifier
BMB CSX-1000 700W 12" 3-Way 5-Speaker Bass Reflex System (Pair)
Acesonic UHF-A6 Commercial UHF True Diversity Wireless Microphone
DAS-300是mixer+amplifier一体的，但是只有四个channel，好处是调起来比较方便，
适合卡拉OK。不好的是以后要接个电吉他啥的就比较吃紧。
如果就是用BMB CSX-1000音箱，但是自己去配mixer和receiver，不知道会不会效果没
有这个好？比如mixer用Yamaha的MG10XU，有10个channel，然后再随便配个大功率
receiver，唱歌的效果会不会差？
