Audio components include a versatile range of amplifiers, receivers and adapters that augment the listening experience. Besides enhancing the quality of sound from different source components, some sound system options provide control and accuracy between various speaker outlets. Look for audio amplifiers that power speakers. Specific adapters and cables help ensure the proper signals go from receivers to other components for improved sound. Look for stereo jack adapters that provide connections between varying size plugs, which lets you add headphones, instruments and other devices to your sound systems.
Receiver elements include an AM/FM tuner, control center and amplifier for controlling and manipulating sound quality. The control center lets you choose the source, and adjusts the quality of sound for connected audio speakers. The audio receiver picks up different AM/FM stations, selects a source component and helps adjust tone quality and other listening preferences. Stereo receivers work with two or more speakers simultaneously, and are best suited for music in multiple small rooms. Modern stereo receivers feature HD tuners with Sirius satellite (XM) capabilities to provide high-resolution audio and radio transmission. Audio/video (A/V) receivers offer surround sound, digital video and audio processing, switching, automatic speaker setup systems and network support.
Different types of audio amplifiers offer varying power ratings, types and number of channels and connections, control setups and other built-in effects. Choosing amplifiers that provide at least twice your speakers’ program power rating offers effective and consistent amplification results. Power amplifiers provide an electric current to the speakers, and come in mono, multichannel and two-channel options that handle different needs. Mono amplifiers power single-channel speakers, making them a good choice for subwoofers and other low-frequency models. Two-channel power audio amplifiers operate in default stereo mode, as each channel receives a mono signal independent of the other. This offers flexibility for use with computer speakers, bookshelf speakers and soundbars, and provides consistent audio quality. The pre-amplifier or control amplifier offers a small amount of amplification, and it is the component from which you can connect and control all other audio system components. It is available as a separate component or as part of the power amplifier, depending on the performance capabilities and user requirements.
Audio cables and connectors work with different surround sound systems, DVD players and a wide range of audio and video equipment to help ensure the correct signals move between the components. The RCA connector adapter features color-coded plugs and sockets for accurate transmission of video signals between HI-FI systems and home audio devices, like home theater in-a-box setups. The phono connector has two cables for the left and right side audio speakers. Musical Instrument Digital Interface (MIDI) cables connect a controller to an interface before it connects to the computer in an audio or music studio. The connection provides control to all the virtual instruments and some audio components within a digital audio workstation.
