How to Properly Use R.F. Amplifier at Home

An RF Amplifier

One of the most popular types of amplifiers is a power amplifier. Its purpose is to supply energy to 1 or multiple speakers. It lacks the additional functions and connections often found in a home theater. These features and connections include a radio, switching input sources, and audio or video (A.V.) synthesis. On an R.F. amplifier, the main gain control is the only controller you will normally see (other than the switch for power). This may be thought of as being equivalent to the volume.

Configurations of R.F. Amplifier Channels

R.F amplifiers are available in a variety of formats, from Monoblock to stereo. Six or more channels can be found in power amplifiers used in surround sound applications. Both 7- and 2-channel R.F. amplifiers can be used when nine channels are required. There are two 2-channel amplifiers connected in series to make up the 11 channels required. It is possible to utilize a Monoblock amp for each channel, which requires heavy amps.

R.F. Amplifier Connection

To get audio signals to a power amplifier, a separate A.V. processor/preamp is necessary. Preamp/processors are used to decode or process audio signals from sources such as a CD player and transmit them to the R.F. amp, which delivers them to the speakers. RCA-type or XLR line outputs transfer analog signals between the preamp and power amplifiers, respectively.

A.V. processor /preamp is where we attach the source to the system like CD, Blu-ray, media streamer, DVD, etc.

A Home Theater Receiver and R.F. Amplifier

Speakers can be powered by built-in amplifiers in home theater receivers. The built-in amplifier power may be limited, but some receivers have preamp outputs that can be used in conjunction with external power amplifiers to increase their output. You’ll need an A.V. receiver and an A.V. processor to use this feature.

There are no amplifiers in the receiver itself in this setup. As a result, if you have a home entertainment receiver and an external power amplifier, you cannot simultaneously use both.

Assume the receiver in your home theater is multi-zone capable. While the receiver’s built-in amplifier is used for the main zone, the Zone two, three, or four preamp output signals will be connected to the speakers’ external amp of power in various locations. If the receiver has 7.1 channels and two preamp outputs, you can avail a dual-channel independent zone. As a result, you can simultaneously run the main 7.1-channel zone and the second 2-channel zone using additional amps for power linked with speakers in the second zone. 


Installing an R.F. amplifier can change your experience of home entertainment. With this article, you can easily connect an R.F. amplifier with your home theater and make the best use of the amplifier at home.
