Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable.
Maybe youve seen or even have an active speaker and there is written 1500 watts PMPO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PMPO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PMPO.

This article describes in easy terms the operation of a Basic Power Supply unit of the kind used with telecommunications instrumentality (switchboards, physics house exchange systems, plan-sets, etc).

The term power provide is a lot of normally abbreviated to PSU, this may be wont to  electronic device to be ready to work. So, the facility supply unit is  use to come up with a voltage that may be supply in associate device in accordance with the wants of the mains voltage from that device. Telecommunications instrumentality and notebook is meant to control on lower voltages than electrics domestic Mains voltage. So as to scale back this voltage a PSU (Power Supply Unit) is employed.

This is achieved by employing a device called a electrical device associate magnetic attraction device consisting of associate ferric email iron core that incorporates a sizable amount of turns of wire wound around it, called the first Winding. The ends of those turns of wire being connected to the input voltage, in this case Mains AC.

A second range of turns of wire-protected measure wound round the coil, this set being called the coil.

The distinction between the quantity of turns provides simplest way of reducing a high AC voltage to a lower one.

To convert our currently low AC voltage to DC we tend to use a Rectifier Diode connected to the coil.

This is a chemical element diode, that has operation analogous to a bicycle tyre valve (as the valve solely permits air to flow into the tyre, the diode solely permits current to flow in one direction).

As our low AC voltage are going to be functioning at a frequency of 50 - 60Hz (Mains AC frequency) its fascinating to scale back the inherent hum on this to a lower level.

This is achieved by a method called Smoothing (filtering out the bumps within the AC).

A simple thanks to scale back the hum is to use Full Wave Rectification.

Today this is often typically done by four diodes during a bridge configuration called a Bridge Rectifier. (This will be four individual diodes or an infatuated self contained package)

The capacitance could be a device capable of storing energy the quantity of energy and therefore the time it remains hold on counting on the worth. In a straightforward PSU the simplest thanks to give regulation to make amends for varied load conditions is to use a try of comparatively high price Electrolytic Capacitors.

Their values during this case being within the between of 470uF to 4700uF counting on the applying and therefore the quantity of current needed from the output of the unit. One of these capacitors and Electrolyte Capacitors is connected across the DC output of the rectifier diode(s) or bridge, this electrical device conjointly providing an additional degree of smoothing the output wave.

The second electrical device is connected via an occasional price, medium to high electric power resistance, that assists in limiting this demand.

While this 1000 Watt Power Amplifier minimal use transformer 20 Ampere. And the output of Power Amplifier DC voltage contains approximately 63 volts, with currents and voltages of this magnitude, this 1000 Watt Power Amplifier will not hesitate hesitate to destroy your woofer speakers to connect. To overcome that then before the speaker on connects to 1000 Watt Power Amplifier must be in pairs Speaker Protector.

Actually if you want to create a Power Amplifier with great power does not have to make a Power Amplifier with great power. Example: you want to create a Power Amplifier with 10 000 Watt power. You do not have to assemble a Power Amplifier with power of 10,000 watts, but you assemble the power Power Amplifier Small but many, such as you assemble the Power Amplifier with 1000 Watts of power for as many as 10 pieces, it will produce 10 000 Watt Power Amplifier helpless.

Circuit uses power transistors pair of 5 x 5 x 2SA1216 and 2SC2922 and 2SC1583 use a differential amplifier that actually contains 2 pieces of transistors that are in containers together. Why use such built-in amplifier differental tujuanya so identical / similar, could have uses 2 separate transistors but can result in amplifier so it is not symmetrical.

Tips combining speaker.

To get the speakers with great power combining techniques can be used in parallel series, combining each group of speakers should sepaker they will have the same impedance, the same type (Woofer, Mid Range or tweeter) and the same power. Number of merging these speakers should consists of 4 , 9, 16 ff, see picture

Example: The number of speakers have 4 pieces each of its 200 Watt power generated will be a speaker at = 200 x 4 = 800 Watt. If there are 9 speakers 200 W then the result = 9 x 200 W = 1800 Watt.
