Phone connector (audio) Phone plug mated in a phone socket. The plug's grooved tip is held firmly by the socket's spring tip contact. When not mated, this spring instead connects to the flat switch contact for detecting a plug. TS and TRS plugs of different sizes. A phone connector is a family of cylindrically -shaped electrical connectors ...
Audio only: Analog: Often unmarked on consumer audio equipment since it is so common, or labelled with headphones symbol or as "line out". Computers and other equipment sometimes use Microsoft-Intel color coding scheme, especially when there are multiple input/output plugs. 3.5 mm TRS minijack RCA connector: Balanced audio
Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles . Generally, line level signals sit in the middle of the hierarchy of signal levels in audio engineering.
Effectively, a headphone amplifier is a small power amplifier that can be connected to a standard headphone jack or the line output of an audio source. Electrically, a headphone amplifier can be thought of as an amplifier that presents a very high input impedance (ideally infinite) and presents a lower output impedance (ideally zero) and larger ...
7.1 surround sound is the common name for an eight-channel surround audio system commonly used in home theatre configurations. It adds two additional speakers to the more conventional six-channel ( 5.1) audio configuration. As with 5.1 surround sound, 7.1 surround sound positional audio uses the standard front left and right, center, and LFE ...
Inrush current. Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.
API. Audio Stream Input/Output ( ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low- latency and high fidelity interface between a software application and a computer's sound card. Whereas Microsoft 's DirectSound is commonly used as an intermediary signal path for non-professional users ...
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers, speakers, headphones, projectors, GPS ...
