To narrow down your choices, answer a few key questions. • Surround sound or stereo? • How many rooms or zones do you want to fill with sound? • Do you want a radio or network music sources built-in? • Do you want to Below you'll find tips on how to choose. To learn more, read our buying guides for A receiver is an amplifier that includes a radio tuner and a preamplifier section. You can connect a variety of source components and at least two speakers. There are three different categories from which to choose: Home theater receivers A home theater receiver (also known as an A/V receiver) supplies at least five channels of power for surround sound setups. It also provides video processing and at least one HDMI output for your TV. Stereo receivers A stereo receiver has two channels of amplification for left and right stereo speakers. It also has an AM/FM tuner, of course. But these days, you're likely to also see multiple analog and digital audio inputs, and Wi-Fi and Bluetooth connectivity. Most models can power a se...

By • What is an amplifier? An amplifier is an electronic device that increases the weak-signal amplifiers or power amplifiers. Types of amplifiers • Weak-signal amplifiers are used primarily in wireless receivers. They are also employed in acoustic pickups, audio tape players, and compact disc players. A weak-signal amplifier is designed to deal with exceedingly small input signals, in some cases measuring only a few nanovolts (units of 10 -9 volt). Such amplifiers must generate minimal internal noise while increasing the signal voltage by a large factor. The most effective device for this application is the sensitivity, defined as the number of microvolts (units of 10 -6 volt) of signal input that produce a certain ratio of signal output to noise output (usually 10 to 1). • Power amplifiers are used in wireless transmitters, broadcast transmitters, and hi-fi audio equipment. The most frequently-used device for power amplification is the Two important considerations in power amplification are power output and efficiency. Power output is measured in watts or kilowatts. Efficiency is the ratio of signal power output to total power input (wattage demanded of the power supply or battery). This value is always less than 1. It is typically expressed as a percentage. In audio applications, power amplifiers are 30 to 50 percent efficient. In wireless communications and broadcasting transmitters, efficiency ranges from about 50 to 70 percent. In hi-fi audio power amplifiers, distor...
