1. Direct Connection: Some surround sound speakers have built-in amplifiers and can be directly connected to an audio device, such as a TV or Blu-ray player, without the need for a receiver. This is common in soundbar setups or simple 2.1 or 5.1 surround systems.
2. Integrated Amplifier: Some surround sound speaker systems come with an integrated amplifier or a powered subwoofer that includes an amplifier. In such cases, the speakers can be connected to the integrated amplifier, and the amplifier can be connected to the audio source.
3. External Amplifier: You can also use an external amplifier to power surround sound speakers. The speakers will need to be connected to the amplifier's speaker outputs, and the amplifier will need to be connected to the audio source.
4. Audio-Video Receiver (AVR): An audio-video receiver (AVR) is a central component commonly used for setting up surround sound systems. It acts as a hub, processing and amplifying the audio signals and distributing them to the appropriate speakers. While an AVR is not strictly necessary for using surround sound speakers, it offers various features and connectivity options for building a comprehensive home theater setup.
It's important to note that the specific setup may depend on the type of surround sound system you have, the features of your audio devices, and your desired configuration. Refer to the user manuals of your speakers, amplifier, or AVR for the recommended connection methods.
