Various Types Of Power Supplies For Wireless Surround Sound Products
While setting up rear speakers for your home theater system, you have several choices. Most people will simply hard-wire the loudspeakers to the home theater receiver. However, some people choose to get rid of the speaker cable mess by making use of wireless broadcast. Next, I'm going to look at the power supplies that supply these kinds of cordless products with energy and make clear several of the most essential prerequisites that these types of power sources must meet.
Both the transmitter and also receiver that are part of the cordless kit need power and consequently have to be plugged into an outlet. Several products have an external AC adapter while some others have an integrated power supply. Both options have got advantages and drawbacks.
By using a wallwart, the cordless receiver can be significantly smaller in proportions. An additional type of wallwart is quite similar to the style used by notebooks because it attaches to a mains electric outlet by means of a short power cord. From the standpoint of a designer, combining a wallwart has numerous positive aspects over a built-in power source. First of all, based on what country the cordless system is going to be sold in, a distinct AC adapter can be included which is compatible with the native mains voltage and electric power plug. In addition, some wallwarts are already approved for safety. This will likely help save a lot of cash compared to having to safety approve the receiver. Also they are less pricey to change in the event of failure rather than exchanging the complete wireless receiver. Wireless surround amplifiers with integrated power source are less difficult to put in given that they directly plug into a mains wall socket. On the other hand, they are typically a bit more bulky.
The power supply should satisfy the regional safety regulations and a number of other requirements. The rules were made to ensure that there's enough protection in order to avoid harm to humans in case of line fault conditions. The insulation from the mains voltage should meet rigid requirements. A different aspect covered by almost all safety regulations is the behavior of the power supply while in normal operation. You can find regulations relating to how warm the power source can become and also how well it's going to safeguard itself in the event of overload or over-temperature conditions.
One other crucial prerequisite is that the power source provide sufficient current to the internal cordless signal receiver as well as power amp. The power supply should be dimensioned big enough to be able to provide the power amplifier with ample current in order to drive a connected speaker at the specified RMS power level for at least 10 minutes. More important than the continuous current rating is the maximum current rating. Music signals hardly ever have a constant energy envelope. Rather, music has a lot of spikes. So the power supply has to be ready to maintain a pretty large top current during brief time bursts. The sound performance of the cordless receiver additionally is determined by how clean the power is that is supplied by the power source. A large amount of voltage noise and also ripple can result in the music performance to degrade. Because of this voltage noise as well as ripple are some additional vital requirements. Some high-end music gear employs linear power supplies regardless of their weight plus size mainly because of the good noise performance. The majority of power sources are switch-mode power supplies. The supply voltages of the RF receive and power amplifier sections usually are different. Consequently plenty of power sources offer more than one supply voltages. Finally, the power source needs to have sufficient overload and over-temperature protection to keep everything secure in the case of a fault of the audio amplifier.
