Mullard Circuits for Audio Amplifiers is a famous book by the Technical Services Department of Mullard Ltd, a British valve manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur constructors as well as by manufacturers as the basis for many ...

Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...
In the early and mid-1970s, for example, Ferguson made two-channel receivers with a built-in Hafler circuit. Philips had a similar circuit in their two-channel receivers. . Many receivers from middle price brands had such circuits, but often without a volume control for the rear chan
The term balanced comes from the method of balancing the impedance of each wire in the circuit; the line and all circuits directly connected to it (such as the driver and receiver) must have identical impedances with respect to some reference point. This means that much of the electromagnetic interference will induce an equal noise voltage in ...
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems.
A wire and connector being crimped together with a crimping tool Main article: Crimp (electrical) Crimped connectors are a type of solderless connection, using mechanical friction and uniform deformation to secure a connector to a pre-stripped wire (usually stranded). [ 1 ]
