Choosing Good Amp Home Theater
If you can see today’s audio Amp Home Theater products, we can not help looking for your choice, we will be overwhelmed by the number of high technology and models. I will explain some basic terms reinforcement and help you choose the best model, no matter what the particular application that may be your choice. Audio amplifier is the basic relationship between your source such as DVD or Blu-Ray player and your speakers. An amplifier will convert the audio source signal is weak enough to be strong enough to drive your speakers. And you’ll enjoy it all the time.

Depending on your application, you may want to go with the source that already has a built-in amplifier. However, using a separate amplifier that will provide more flexibility in selecting the most complete model of your speakers. Some current models of mini amplifier small enough to hide could almost anywhere.
When you start choosing an amplifier, your first consideration is probably the wattage output of the amplifier. You will need a higher wattage if you operate the speakers with low sensitivity (in dB / W), for driving speakers in large rooms or outdoor speakers. However, be careful not to overdrive your speakers. This can damage your speakers. Furthermore, do not worry too much about watts. Amp supply 20 to 50 Watts will give a lot of strength to drive speakers in the space of any kind.
Power amplifier output is given as Watts RMS (continuous) and peak Watts. Rms or continuous value tells you how many high power amplifier capable of providing continuous, while the maximum peak power wattage figure tells that the amplifier can provide for short periods of time. You must choose the amplifier that has enough power rms, although 10 to 30 Watts should be a lot for most applications but has enough space for the peak that occurred in the music signal.
There is another measure that is important than wattage when choosing an amplifier. One important parameter called the total harmonic distortion or THD for short. No amplifier is really perfect and amplified signal components will include some errors that will change the signal to some degree. THD is well expressed in percent or dB. A number of smaller distortion is lower than the audio signal to the amplifier. Audiophile amplifiers will have a total distortion of less than 0.05%. Consumers will have a value class amplifier distortion to 10%.
Later, another specification called the ratio of signal-to-noise. This amount it determines how many components you do not want such as hum and noise amplifier which will add the audio signal. High-end amplifiers to achieve the ratio of signal-to-noise ratio of at least 100 dB, while consumer grade amplifiers will usually have a signal ratio of at least 80 dB.
You should know that the majority of the current amplifier based on a technology called Class-D that offers higher power efficiency than the amplifier based on a Class-A or Class-AB technology. Higher efficiency means that less power is wasted as heat can make the amplifier is quite small. Some mini amplifier that is being developed at this time no bigger than a deck of cards. However, when selecting a Class-D (digital) amplifier, make sure that you have an amplifier, low distortion and high ratio of signal-to-noise.
