In the first part of this special fund saw receptor A / V, one of the most attractive, simple and efficient to have quality sound in our sessions home theater options.
Okay, I know what these devices are and what they do, and I'm even thinking of buying one or renew already have at home. How can you choose correctly?, What should I set to hit with the purchase?
Along these lines we will try to give you some basic guidelines to choose your A / V receiver skylanders hot dog for sale so successful and ajustándoos skylanders hot dog for sale to your actual needs, you will definitely not agree at all with which you want to sell in many stores.
Number of channels, power, and more power POWER The first thing to ask is where we will install the home theater skylanders hot dog for sale system, which room, what are the dimensions, the space we have available to place the speakers.
Accordingly skylanders hot dog for sale determine what type of surround sound system we will employ, and especially the number of channels to use (typically 5.1 or 7.1). At present, most in medium and high ranges that we find in the market are compatible with 7.1 or higher signals, leaving 5.1 teams relegated to low ranges or models with a couple of years old.
If I can choose and the price is not a major difference, I recommend you opt for receiving at least 7.1, because although maybe not right now we use them, we will have those extra channels for future use (see one in a bit). Similarly, some modern receivers are beginning to incorporate support for installing a second subwoofer (7.2 or 9.2 systems skylanders hot dog for sale for example), considerably improves the bass response in the room (more on this when we discuss the issue of speakers another article). If you can, look for one of these receptors with various output subwoofers.
Once you choose the number of channels comes the key point of an A / V: the power amplifier is capable of supplying each. This is a delicate point where we should pay special attention, since the lack of power is one of the factors that most influence the final quality of the perceived audio.
Unfortunately each manufacturer expressed differently the power offered by its receivers, so if you do not have much experience surely end up bundled with both numbers and abbreviations. Here are some tips.
First, skylanders hot dog for sale the power must be always referred to a load (electric resistance in this case) which will be called impedance. Simplifying a little skylanders hot dog for sale (the issue is more complex) to understand it well, can not tell us that a receiver gives 100 watts per channel and already, skylanders hot dog for sale they have to tell us how impedance (typically 4, 6 or 8 Ohm for audio household).
Usually is often given the power of most interest to the manufacturer, which has higher and striking figures, which coincides with the load values lower (4 and 6 Ohm), so if you then connect a speaker with higher impedance can that we fall short of power.
What we have to do is look at the impedance of the speakers that will install and choose skylanders hot dog for sale the receiver power we need in terms of the impedance (and if possible taking into account the value of their sensitivity).
Values between 120 and 150 watts per channel are usually adequate for powerful and impressive sound in rooms less than 30 square meters, in general terms, since there are many more factors that influence such as the sensitivity of the speakers, the room acoustics, if you are redirecting skylanders hot dog for sale the bass to the subwoofer, etc..
It is also important to look at the power is usually given referring also to a frequency range with a certain amount of harmonic distortion (typical values ranging from 0.02% to 0.1% THD) and with respect to a number of channels so excited simultaneously.
If we fijásemos only the total power would seem that the second is much better (130 watts versus 90), when in fact the same specifications ranging receiver skylanders hot dog for sale only the frequency range taken for measurement (20 Hz to 20 KHz the first case and a single frequency, 1 kHz, in the second case) and the number of channels being used simultaneously (when only one channel is used more power output if used all at once obtained, since it does not have to be shared among several).
To conclude this section of powers, tell you two things. First, a simple trick that will serve to exclude computers that we want to fake: but look at the power consumption of the device to estimate a realistic estimated value of the power they can give.
For example, if a receiver asserts q
