Do I need a weatherproof amp or receiver for outdoor speakers?
People who are interested in setting up an outdoor sound system often wonder and ask if they need a special type of “outdoor” or “all-weather” amp or receiver – something that’s also weatherproofed and specifically designed to sit outside – to power outdoor speakers. The answer to that is actually no.
What is a resistive power supply for audio amplifiers?
This project introduces an improved design of a power supply for audio amplifiers (see Photo 1) that behaves like a resistive load with respect to the mains network. Thus, the current drawn from the mains has the same shape as the voltage delivered by the mains and has the same phase, so that the power factor is very close to 1.
What makes a good outdoor speaker?
Power handling is arguably the most important metric of quality for outdoor speakers, particularly because sound doesn’t carry as well outdoors. And the amplifier or receiver has to be able to supply enough power to the speakers.
Does an ecological power supply appeal to audio enthusiasts?
Photo 1: I have designed an ecological power supply that should appeal to audio enthusiasts. This project introduces an improved design of a power supply for audio amplifiers (see Photo 1) that behaves like a resistive load with respect to the mains network.
How many outdoor speakers can a 2 channel amp support?
The number of open channels an amp has is the same number of outdoor speakers it can support. For example, a 2 channel amp can support two outdoor speakers, or perhaps a 7.2 receiver with a 5.1 home theater system already connected to it could additionally support two outdoor speakers and one outdoor subwoofer.

Basic Introduction to Power Amplifier
Power amplifier refers to an amplifier that can generate the maximum power output to drive a certain load (such as a speaker) under a given distortion rate. The power amplifier plays a pivotal role of "organization and coordination" in the entire audio system, and to a certain extent dominates whether the entire system can provide good sound quality output.
power supply
If you want to be able to drive the speakers at full power continuously: Total power [Watt] = number of channels × power per channel . P = 2 × 2.8 = 5.6 W. Supply current drawn for the speakers alone would be: Current [Ampère] = Power [Watt] / Voltage[Volt] I = P / V = 5.6 / 5 = 1.12 A. Accounting for efficiency, you are looking at 1.12 / 0. ...

AN-22 Single Supply Operation with Power Op Amps
The major reasons for operating a power op amp with a single supply voltage are system cost and/or weight. While providing ±15 volts for a small signal op amp may not entail much cost a second power supply that can provide 10 or 20 amps at 50 or 100 volts would be of considerable expense and weight.
Introduction to Power Amplifiers
Voltage and current amplifiers can make use of small transistors and do not draw large amounts of power from the power supply in order to amplify signals by often, very large amounts. However the small transistors they use have very tiny junction areas and so cannot handle the power needed to drive some output devices without overheating.
