Receiver vs. Amplifier vs. Preamp
| Receiver | Amplifier |
|---|
| Info | Often contains an amp and preamp, along with other functionality | You need as many channels as you have speakers, and most amps will contain up to 7 channels |
| Is it necessary in a home theater? | Yes | Yes if you don't have a receiver |
| Cost | Moderate to high | Low to moderate |
You cannot magnify the power of one amp by chaining it to another. For instance, you can put the RCA analog stereo output into another stereo amp's RCA input, and drive more speakers with that amp. Or you can connect the amps with digital connections. That's the way to do it.
A better amp will make your speakers play louder and sound better, but it won't make bad speakers sound like good speakers. Many speakers have a "maximum wattage rating" on the back. High-end amplifier companies make amps with more than 1,000 watts, and you could plug in a $50 speaker into it with no problem.
The power amplifier is what powers speakers. An integrated amplifier integrates a pre amplifier with a power amplifier. The pre amplifier handles volume control, input switching, sometimes a phono pre amplifier is included, and often includes some other controls like tone controls, balance, speaker switching.
Okay, so you have a preamp that you need to hook up to your AV receiver. Hooking up a preamp to your AV receiver is pretty simple if your receiver has the capability: Find the AV receiver's Home Theater (HT) Bypass or Direct In port. Plug the output of your preamp into the HT Bypass/Direct In input of your receiver.
For traditional speakers, a receiver is highly recommended, almost always required. For active Soundbars with wireless or satellite speakers, a receiver is not needed. Passive Soundbars will require the use of a receiver.
Any AV receiver can be utilized as an external power amplifier (via another unit's preouts) even if it does not have multichannel inputs, but only for two channels. Use any analog source input (left and right channel jacks), such as CD or auxiliary (but not phono).
An amplifier boosts the low-level audio signal generated by the head unit so that it's powerful enough to move the cones of the speakers in the system and create sound. But before the signal can be amplified, it has to be processed by a preamplifier or "preamp."
An integrated amp is the right choice if you want all to connect all of your music sources to a dedicated two-channel amplifier using one component. And most of them can accomodate wireless music streaming, too.
The answer. So when it comes to whether a preamp can be used as an amp, the short answer is no. A preamp simply doesn't work with as much power as an amp and so wouldn't be able to boost the line signal enough to be heard on the speakers. A preamp simply boosts a weak signal, whereas an amp can do so much more.
Yes. A turntable must be connected to an amplifier as the output signal is not strong enough to drive speakers. So if you have a turntable with a built-in preamp and also have speakers with a built-in amplifier, then you connect the two without the standalone amplifier.

A stereo receiver is very basic. It only handles audio signals and can come with input selection, radio tuner, volume control. It will have a built-in amplifier but usually only two channels (stereo is two left and right channels). More often than not, a stereo receiver is more than you'll need for playing music.
Power Amplifier. The basic difference is this: a preamp boosts a weaker signal to line level, while an amplifier boosts a line level signal so that it can be sent to speakers.
Subwoofers are designed to increase the bass frequencies, resulting in a deep, thumping sound. In most cases, they are paired with an amplifier to boost the sound. If you do not have the funds for both components, you can still hook up a subwoofer without an amplifier; it simply involves a little more know-how.
All you need to do is connect the AUDIO OUT to the TV's HDMI port. After that, use the amplifier's output connection to connect it to the speaker. If you think about it, the two-channel amplifier literally acts in the same way as a receiver, so there's not a lot of difference in terms of connection.

Make sure you look into the units inputs and outputs, as this will determine what you can connect to it. Also think about the power output of the amp and how you're going to be listening to your system. There's no need to invest in an amplifier with a huge power output for standard volume listening session.
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
Yes, an active preamp is an line level amplifier. You will get a lot more gain from it than just the standard componant line level. You will however NOT get any more power from your amp, so be careful not to overdrive it! Think of the preamp volume control as the throttle for an engine.
Entirely possible. A pre does two things. One, bring the voltage (and impedance) of the input source to a level where the power amp can deal with it easily.
To check if a receiver has a built-in preamp, check if the receiver has a PHONO input. A receiver with a PHONO input definitely has a built-in preamp. If your receiver has a PHONO input, you can connect a turntable without a phono preamp to that input. This way, you will use the preamp that is built into the receiver.
It switches low-level signals from audio and video sources to the audio amplifiers, which boost the preamp output sufficiently to drive the speakers. The preamp always includes the volume control. In extremely high-end systems, the preamp and amplifier are separate components (see audiophile).
A preamplifier (preamp or "pre") is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker.
