A paralleled amplifier configuration uses multiple amplifiers in parallel, i.e., two or more amplifiers operating in-phase into a common load. In this mode the available output current is doubled but the output voltage remains the same. The output impedance of the pair is now halved.
Horizontal bi-amping has the advantage of allowing two different amplifiers that sound better than each other for bass or for treble. Vertical bi-amping uses two channels of an amplifier per loudspeaker, with a dedicated channel for the bass driver and a dedicated channel for the treble or the treble and the midrange post-amplifier together.
Simplified diagram of a 2-stage cascaded amplifier. A multistage amplifier is an electronic amplifier consisting of two or more single-stage amplifiers connected together. In this context, a single stage is an amplifier containing only a single transistor (sometimes a pair of transistors) or other active device.
Darlington Transistor (NPN-type) In electronics, a Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one.

The search for volume was taken on its next logical step with the advent of "daisy chaining" two or more amplifiers together. As most amplifier channels have two inputs, the guitar signal being present on both sockets, the cunning musician hooked the spare input of one channel to an input on another amplifier.
(Edit) The statements above fail to mention that when two amplifiers are connected in bridge mode the output impedance of the pair is DOUBLED. Thus, if "2R" is substituted for "R" in the formula given, (together with the implied "2Vsquared) it will be seen that the output power is also DOUBLED and not quadrupled as stated.
Johnny Depp is keeping his late friend Jeff Beck in mind.. More than two years after Beck died at 78 in January 2023, Depp, 61, shared a video on Instagram on Sunday, Jan. 19 in which the actor ...
The use of a cascode (sometimes verbified to cascoding) is a common technique for improving analog circuit performance, applicable to both vacuum tubes and transistors.The name "cascode" was coined in an article written by Frederick Vinton Hunt and Roger Wayne Hickman in 1939, in a discussion on the application of voltage stabilizers.
