Differences between receivers, integrated amplifiers and discrete components

The components of a stereo sound system can be confusing for someone just starting out. What are the differences between receivers and amplifiers? Why would you choose to have a system made up of separate components and what does each component do? Here is an introduction to the components of sound systems so you can better understand the role each plays in your listening experience.

The receiver is a combination of three components: an amplifier, a control center and an AM/FM tuner. The receiver is the center of the system to which all audio and video components and speakers will be connected and controlled. A receiver amplifies the sound, receives AM/FM stations, selects a source for listening and/or viewing (CD, DVD, tape, etc.), and adjusts tone quality and other listening preferences. You can choose from a variety of receivers, including stereo and multi-channel home theater receivers. Your decision should depend on how you will use the receiver. For example, if you like listening to music more than watching movies, you probably don’t want an omnichannel receiver. A stereo receiver and a CD or DVD player and two speakers would be a better choice.

An integrated amplifier is like a receiver without an AM/FM tuner. A basic integrated amplifier combines a two-channel or multi-channel amplifier with a pre-amp (also known as a control amplifier) ​​to select audio components and drive tone controls. Built-in amplifiers are often accompanied by a separate AM/FM tuner.

Separate components: preamps and power amps

Many serious audiophiles and very demanding listeners prefer separate components as they provide the best audio performance and each component is optimized for its particular function. Also, because they are separate components, there is less chance of interference between the preamp of a power amplifier and the higher current stages.

Service or repair may also be important if needed. If a part of an a/v receiver needs repair, the entire component must be taken to a service center that does not require separate parts. It is also easier to update individual components. If you like the preamp/processor but want more amp power, you can buy a better amp without replacing the preamp.

Preamplifiers or Control Amplifiers

A preamp is also known as a control amplifier because it is where all components are connected and controlled. A preamplifier provides a small amount of amplification, just enough to send the signal to the power amplifier, which amplifies the signal enough to power the speakers. Receivers are great, but if you want the best performance without compromise, consider separate components.

power amplifiers

A power amplifier provides electrical current to drive the speakers, and they are available in two-channel or multi-channel configurations. Power amplifiers are the last component of the audio chain before the speakers and must match the specifications of the speakers. In general, the power output of the amplifier should match the power handling capabilities of the speakers.

Differences between receivers, integrated amplifiers and separate components

The components of a stereo audio system can be confusing for those just starting to put together a system. What are the differences between receivers and amplifiers? Why would you choose to have a system of separate components, and what do each of them do? Here is an introduction to the components of audio systems so you can better understand the role each one plays in your listening experience.

There are many receivers to choose from, including stereo and multichannel home theater receivers. Your decision should be based on how you will use the receiver. For example, if you enjoy listening to music more than watching movies, you probably won’t want a multichannel receiver. A stereo receiver and a CD or DVD player and two speakers would be a better choice.

A basic integrated amplifier combines a two-channel or multichannel amp with a pre-amplifier (also known as a control amp) for selecting audio components and operating tone controls. Integrated amplifiers are often accompanied by a separate AM/FM tuner.

Separate Components: Pre-Amplifiers and Power Amplifiers

Many serious audio enthusiasts and very discriminating listeners prefer separate components because they provide the best audio performance and each component is optimized for its specific function. In addition, because they are separate components, there is less possibility of interference between the pre-amp and the higher current stages of a power amp.

Service or repair can also be important, should it become necessary. If one part of an a/v receiver needs repair, the entire component must be taken to a service center, which is not true of separates. It is also easier to upgrade separate components. If you like the pre-amplifier/processor, but want more amplifier power you can purchase a better amp without replacing the pre-amp.

Pre-Amplifiers or Control Amplifiers

A pre-amplifier is also known as a control amplifier because it’s where all components are connected and controlled. A pre-amp provides a small amount of amplification, only enough to send the signal to the power amplifier, which amplifies the signal enough to power speakers. Receivers are excellent, but if you want the best, no-compromise performance, consider separate components.

Power Amplifiers

A power amplifier provides the electrical current to drive loudspeakers and they are available in two-channel or several multichannel configurations. Power amps are the last component in the audio chain before the loudspeakers and should be matched with the capabilities of the speakers. In general, the power output of the amp should be closely matched with the power handling capabilities of the speakers.
