An amplifier is a special form of audio equipment that adds power and volume to a stereo system. This is accomplished by sending additional wattage to the speakers through multiple channel outputs. This is typically used for splitting music among rooms of a home or building, including both interior and exterior speakers.
8-channel amplifiers are designed to manage multiple feeds into a stereo system. This type of high-end audio equipment is often used in music editing studios. The unit provides a separate balanced stereo output for each channel. This enables music to be pulled from multiple types of audio equipment, so it can be mixed to produce a unique sound.
Outdoor speakers are good options for pools and patios. These types of speakers are typically run on multi-channel amplifiers that can play music through different zones. An 8-channel amplifier is good for buildings that require multiple audio speakers.
A detached garage can be connected to a home audio system by using a multi-channel amplifier. This enables music to be played inside the garage from a central audio receiver inside the home. Having a multi-channel amplifier adds flexibility and expandability to an audio system that is not available with a standard amplifier.
Intercom systems in schools and large commercial buildings require separate audio channels. An 8-channel amplifier is a good option for a building that requires eight distinct channels of audio. This is typically used in car dealerships and small warehouses where multi-channel intercoms are required.
A typical home theater system needs at least five to seven audio channels. These are divided into the front, rear, center, and surround speaker channels. An 8-channel amplifier is typically recommended for a home that uses a home theater in one room and a separate stereo system in another room.
Most large schools use multi-channel amplifiers for the intercom systems in the classrooms. These systems allow people in a central office to have direct voice access to each classroom. The amplifier device is connected to each classroom, which provides two-way radio communication to each teacher.
An 8-channel amplifier is also used in many department stores. This allows different types of music to be played in specific areas of the building. A multi-channel amplifier is able to play different audio equipment for each channel, which makes it extremely flexible. One channel can be connected to a radio receiver, while another channel can be connected to digital audio.
