Methods To Make Sure That Your Network Speakers Will Last

If you recently purchased a home theater system or a pair of cordless speakers, you may require some suggestions on correctly setting it up if you don’t want to contract an installer. You may think you are technically savvy and that installing your new home theater system will be a snap. I am going to offer several recommendations that will help you steer clear of some usually made errors.

After unpacking your new home theater system, you are going to generally find one central component and five or seven loudspeakers. The main component is going to deliver the signal for every one of your loudspeakers that you are going to install. This central component is also called surround sound receiver or amplifier. It is the central hub of your home theater system. Put this receiver in a place that minimizes the loudspeaker cord run to each loudspeaker. Just be sure it is in a dry and safe place. Moreover, be certain that you can easily reach the receiver from your television set or DVD/Blue-ray player because you will need to connect these. The receiver requires an audio signal in order to deliver surround sound. Normally it is going to accept an optical surround sound signal. You may connect this input to your television set by using a fiberoptical cable. This cable is usually included with your system. You can also get it a most electronics stores. After you have established the audio link to your television set, you may now proceed and attach your loudspeakers. This step requires a bit more work.

If you have cordless rear speakers you will not need as much speaker cable and the install is going to be somewhat easier. First of all, measure how much speaker cord you are going to need. Make sure to add some extra cable in order to take into account those twists and corners. If you are planning to drive a lot of output power to your speakers then make sure you choose a cord which is thick enough to handle the current flow. Your woofer normally is going to be an active woofer. This means that it is going to accept a low-level music signal. You can attach your subwoofer via an RCA cable.

Whilst attaching the speaker cord, be sure that you attach the cord with the accurate polarity. Each speaker offers a color-coded terminal, generally red and black. Choose a loudspeaker cable which is color coded to help ensure the correct polarity while attaching to the speaker terminal. In the same way, watch the correct polarity while connecting the speaker cord to your surround receiver to keep all of your loudspeakers in phase. If you are using wireless speakers, there will be a short audio delay incurred throughout the audio transmission to the speakers, also known as latency. Normally the latency ranges between one and twenty ms. For best result, it is best if all of the loudspeakers are in sync. If you have cordless rears then the audio will by to some extent out of sync with your remaining speakers. To keep all speakers in sync you are going to have to tweak the receiver to delay the signal going to your wired loudspeakers.

Check the user manual in order to find out how to set a delay on specific channels. Home theater systems that were not intended for cordless rear speakers might not come with this capability. In this case you may want to look for a wireless speaker kit which has very low latency, ideally less than one ms. This will keep all of your loudspeakers in perfect sync.


Purchasing A Couple Of Efficient Wireless Loudspeakers

I’ll take a look at the expression “power efficiency” that shows you how much wireless speakers waste so that you can select a pair of wireless speakers.

The less efficient your wireless speakers are, the more power will be squandered which results in a number of issues: A great deal of squandered power clearly implies larger operating cost which means that a more pricey set of wireless loudspeakers can in fact in the long run possibly be less costly than a less expensive model which has lower efficiency. Lower efficiency cordless speakers will dissipate a great deal of energy as heat. Cordless loudspeakers with small power efficiency routinely have a number of heat sinks to help dissipate the wasted power. Heat sinks and fans demand space and are expensive. The wireless speakers therefore is going to get fairly large and expensive. Additionally heat fans are going to create running noise. Low-efficiency wireless speakers further require a good amount of circulation around the wireless speakers. Thus they can not be placed in close spaces or within air-tight enclosures. Cordless loudspeakers that have low efficiency have to have a bigger power source in order to output the identical level of audio power as high-efficiency products. An increased amount of heat causes additional stress on components. The lifespan of the cordless loudspeakers may be decreased and dependability could be jeopardized. High-efficiency cordless loudspeakers in contrast do not suffer from these problems and can be built very small. The efficiency is shown as a percentage in the cordless speakers data sheet. Different amplifier topologies deliver different power efficiencies. Class-A amps are amongst the least efficient and Class-D the most efficient. Typical power efficiencies vary from 25% to 98%. The larger the efficiency figure, the less the level of power squandered as heat. A 100-Watt amplifier which has a 50% efficiency would have a power consumption of 200 W.

What is less known about efficiency is the fact that this value is not fixed. Actually it varies based on how much energy the amp delivers. As a result in some cases you can find efficiency values for different power levels in the data sheet. Every audio amplifier will consume a certain amount of energy irrespective of whether or not it supplies any kind of power to the speaker. That is why the lower the power the amplifier provides, the smaller the efficiency. As a result audio producers usually specify the efficiency for the highest audio power that the amplifier can deliver. To determine the power efficiency, the audio power that is consumed by a power resistor that is attached to the amp is divided by the total energy the amp uses while being fed a constant sine wave signal. Usually a complete power report is plotted to show the dependency of the efficiency on the output power. Due to this the output power is swept through different values. The efficiency at each value is measured plus a efficiency plot generated. When choosing a set of cordless loudspeakers you have got to weigh efficiency versus fidelity since wireless speakers which employ low-efficiency analog amplifiers often offer the largest audio fidelity whilst digital types will have bigger distortion. Having said that, digital amps have come a long way and are offering improved audio fidelity than ever before. Cordless speakers that employ Class-T amplifiers come close to the audio fidelity of types that have analog amps. Due to this fact picking a pair of cordless loudspeakers which use switching amplifier with great music fidelity is now possible.
