Home sound equipment typically consists of a set of stereo speakers and a subwoofer connected to an amplifier within a home setting. Stereo, or stereophonic sound, refers to the ability to create directional sound from two separate speakers. From stereo, this concept has evolved into multichannel sound.

Multichannel sound, commonly known as surround sound, utilizes around 7 independent sound channels or speakers. It is often referred to as 5.1, 6.1, or 7.1 channel sound.

Home stereo systems are connected to create a 5.1 channel surround sound. In a 5.1 setup, there are five satellite speakers along with a single subwoofer. This configuration is an industry standard for TV shows and music, with five channels of audio and a sixth bass speaker or subwoofer channel used for special effects like bass sounds in pop music.

A 6.1 channel sound system adds an additional center speaker placed between the two surround sound speakers behind the listener. This setup provides a more immersive surround sound experience.

A 7.1 channel sound system is a further advancement to 5.1 channel sound, with two additional side-surround home theater speakers positioned to the sides of the listener’s seating area. 7.1 channel sound is commonly used for more precise positioning of sound effects.

Additionally, there is the standard 2.1 setup, which consists of two speakers and one subwoofer. This is commonly used for gaming applications and personal computers.

It’s worth noting that 2.1 channel systems have specialized software that can simulate more complex surround effects using only two speakers. This is known as Virtual Surround Sound (VSS). VSS creates a virtual multichannel surround sound experience using two front speakers and a subwoofer. By utilizing 5.1 channel decoders and incorporating special digital circuits that replicate the sound of back channel speakers, a 2.1 stereo system can create a simulated multichannel sound effect.
