Schematic symbol for an OTA with differential input. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op-amp, it has two additional biasing inputs, I abc and I bias.
Here especially, impedance-matching volume controls can be used to protect the amplifier from overload. This system design is otherwise the same as a single source, single zone in that all zones must listen to the same audio source, though volume control is independent in each room (and audio can be turned off in rooms, as desired).
Single-ended signaling is the simplest and most commonly used method of transmitting electrical signals over wires. One wire carries a varying voltage that represents the signal, while the other wire is connected to a reference voltage, usually ground .
A genuine Signetics NE5532N in PDIP package, made in 1990, on a modem board A Texas Instruments SA5532A in SOIC package on an audio distribution amplifier board . The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.

A stereo class A single-ended design with KT88 kinkless tetrodes which produces 15W of output power per channel, and 5W when triode-connected, is the Antique Sound Lab MG-SI15DT. [2] By comparison a pair of the same tubes in class AB push-pull claim to output about 50W at 1% distortion (higher powers at high distortion are quoted for guitar ...
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
In electronics, a common-source amplifier is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage or transconductance amplifier. The easiest way to tell if a FET is common source, common drain , or common gate is to examine where the signal enters and leaves.
